0. Manual

• Mr. Bloomingdale, an aggressive and energetic man, was named president of Diners’ Club, New York, in 1955 and chairman of the board in 1964. Although he retired from the company in 1970, he remained as a consultant. - NYT, August 24, 1982, Section B, Page 10

'’About the only asset we had when we started was $35,000 of uncollectable receivables,’’ Mr. Bloomingdale recalled. ‘‘I had 15 percent of the consolidated company’s stock.’’

• The timing of the Diners’ Club launch was perfect. During World War II expense accounts had proliferated as a way companies could use income for entertaining clients rather than hand it to the government as a tax on “excess” profits (profits greater than those before the war). Now, in 1950, the excess profits tax lifted at the end of WWII was only a few months away from reinstatement for the Korean War.

The growth of T&E credit cards went hand in hand with the growth of expense accounts. As one publication put it, credit cards were spinoffs of expense accounts. And, each time the IRS tightened up its requirements for itemizing deductions, more credit card applications came in.

Following quickly on the heels of the Diners’ Club launch came many others: Dine ’n Sign, National Credit Card, Your Host, Inc, Duncan Hines’ Signet Club, the American Hotel Association’s Universal Travelcard, Hilton’s Carte Blanche, the Esquire Club, and the Gourmet Guest Club (the last two linked to Esquire and Gourmet magazines). A smaller Diners’ Club continues today, but the only other survivor is American Express, which inaugurated its credit card in 1958, then quickly rose to the top of the T&E field.

Traveling salesmen and men (rarely women) in industries such as public relations, advertising, publishing, manufacturing, and wholesaling were fans of the convenience of charging business meals. And, of course, in the early days of T&E club cards it was a status factor to simply dash off a signature on a slip, particularly if the lunch took place in a top restaurant

Expense accounts and credit cards were a boon to restaurants. There were estimates that in the mid-1950s 50% to 80% of meals in high-priced restaurants were “on the company.” Vincent Sardi admitted that a big chunk of his NYC business was made up of men on expense accounts. Peter Canlis, of Seattle’s first-class Canlis Restaurant, said in 1953 that he decided to establish a restaurant there because “a lot of good expense account money wasn’t being spent because there was no place fancy enough to gobble it up – and I was happy to fill the gap.”

The Diners’ Club lowered its transaction fees in 1966.

• His present position with the Diners Club came out of a competing credit card on the West Coast that he started in 1950. That credit card—Dine and Sign—was organ- ized about the same time as Diners Club. Before the end of 1950 the two systems were merged. In an interview last week, Mr. Bloomingdale recalled how a friend had drawn his attention to the Diners Club here in the East, when he had just started his Dine and Sign in Los Angeles. He met with the Diners Club’s founders, Frank McNamara and the late Ralph E. Schneider, but couldn’t make a deal with them at a first meeting. “At a subsequent meeting, we made a deal,” Mr. Bloomingdale said. “About the only asset we had when we started was $35,000 of uncollectable receivables. I had 15 per cent of the consolidated company’s stock, Ralph Schneider had 15 per cent and Frank MacNamara had 70 per cent. Two years after our merger we bought Frank out for about $250,000, paying him out of earnings.”

[1954] Four years ago three men got together in New York City and founded a little organization they called the Diners Clubthe idea being that members could use a single credit card for a group of designated restaurants, hotels, auto rental, and floral establishments. The club now has more than 160,000 membersThe founders began with nine restaurants on their list. Now there are more than 3,000 restaurants, hotels, and other businesses including establishments in such far away places as Switzerland, North Africa, and Hawaii. The clubs volume is approaching 3 million dollars a month. Ralph Schneider, New York City Attorney, and Alfred Bloomingdale, Los Angeles, a member of the New York department store family, were tow of the founders and now are co-owners of the club. The third of the trip of founders, Frank McNamara, sold his interest in 1951 to the other twoSchneider and Bloomingdale said recently that the highest single bill ever run up by a club member was a $24,000 check charged to a card issued to Metro-Goldwyn-Mayer studios on the west coast. The smallest is charged almost daily by a New York banker35 cents for an ice cream soda at a Madison Av. Restaurant. Schneider said more than 85 per cent of the members pay their bills within 30 days. —Club Grows from 3 Diners to 160,000 in Four Years, Chicago Daily Tribune, October 24, 1954 (p. A13)

A compelling reason for the increase is the stricter set of rules laid down by the Internal Revenue Department requiring spenders to itemize reimbursed expenditures. Another, is the pleasant club-like feeling that derives from walking into a beanery and paying for dinner with a card instead of cash. On the other hand, it is no secretthat a charge account customer will spend up to thirty per cent more if he doesnt have to count out the greenbacks on the spot. —Just Write It on the Tab, Joe, Horace Sutton Washington Post and Times Herald, September 21, 1958 (p. C14)

The first charge card is said to have appeared in February 1950. After dining at Majors Cabin Grill in Manhattan, Frank McNamara was embarrassed to discover that he had left his wallet in another suit. His wife paid the bill, but the experience left him thinking about a better solution. At a later meal at Majors McNamara presented a small cardboard card bearing his signature, which he called a diners club card, and said he wanted to sign for the meal the way members at a private club do and be billed later. He was well known at Majors, and the restaurant decided to accept his idea. Encouraged, Mr. McNamara and his lawyer founded Diners ClubThe first card was offered to 200 people, mostly Mr. McNamara’s friends and acquaintances. Fourteen Manhattan restaurants agreed to accept it. A year later, the company estimated that 42,000 Americans were carrying the card and that more than 330 businesses were accepting it. Membership cost $3 a year. At first, all cards were charge cards, remaining that balances had to be paid in full each month. Revolving credit cards, which charge interest and allow customers to make partial payments each month, were introduced in 1951 in New York City by Franklin National Bank. —Credit Cards at 50: The Problems of Ubiquity, New York Times, March 12, 2000 (p. BU11)

1. Before Diners Club: the setting

• By the late 1940s charge accounts and installment credit were already widespread. The founders of Diners Club introduced no radically new ideas — they combined well-known credit techniques and changed the way credit was delivered: the novelty was a third party interposed between the grantor and the user of credit. — MAN pp. 10 (ch. 2 opening), 3.
• The pioneering insight: sell credit itself as a product. Store charga-plates and oil-company courtesy cards existed to sell merchandise and gasoline; Diners Club’s card existed to sell credit. — MAN p. 3.
• Restaurant charge accounts were ubiquitous in Manhattan before Diners Club: “within a mile of where they sat were all of the important restaurants of New York, every one of which offered charge accounts to its regular customers.” Bloomingdale personally had accounts at “21” and most other important restaurants. — MAN p. 3.

2. Frank McNamara and Hamilton Credit Corporation

• Francis X. McNamara was head of an unsuccessful finance company, the Hamilton Credit Corporation, which at the time had $35,000 of uncollected and probably uncollectable receivables and little more. Possibly because of his frequent involvement in litigation, he operated out of the office of his attorney, Ralph Schneider, who gave him the use of a desk. — MAN pp. 1–2.
• Before Hamilton Credit, McNamara had owned a canvas-manufacturing company. Schneider had entered private practice after years with the Office of Price Administration (price controls) during WWII. — SIM p. 23.
• Incorporation (primary source): the corporate entity that became Diners Club was incorporated in New York on 24 March 1949 as “Hamilton Credit Corporation” (NY DOS document #61961), renamed “The Diners’ Club, Inc.” on 29 September 1955, then Citicorp Diners Club Inc. (1983) and Diners Club International Ltd. (1986). So the “1949” in the blog’s current text is right for the entity, but the name dates to
  1. — DOS; filing history listed on aggregator mirrors of the NY DOS record.

3. The real origin: the Bronx charge-account middleman

• Per Bloomingdale, the actual conceptual germ: one of Hamilton Credit’s clients, a Bronx businessman, lent his store charge accounts to his poor neighbors (e.g., for a midnight prescription), collecting a markup over time. Hamilton Credit had lent him $3,000 and McNamara needed the capital back. The twist that intrigued McNamara: a middleman using his own creditworthiness to obtain credit from a store and re-extend it to someone else. — MAN pp. 1–2.
• Discussing it at lunch, the three men saw two flaws in the Bronx scheme: he was lending to the wrong people (poor people least able to repay) and had to wait for an emergency before anyone used the service. Restaurants offered the opposite: steady, predictable use by people who could pay. — MAN p. 3.

4. The Major’s Cabin Grill lunch (1949) and the 7%

• In 1949 Bloomingdale — former Broadway/film producer, grandson of the founder of the Bloomingdale’s store — was back in New York visiting his ailing father when he ran into McNamara, who invited him to lunch at Major’s Cabin Grill (next to the Empire State Building; the owner was “Major” — Compson Satz per Simmons’s account of the staff speech, SIM p. 17). Over lunch the third-party credit card was conceived. — MAN p. 1.
• The famous 7%: in their excitement they called over Major, the proprietor, and asked how much he would pay for business he would not ordinarily get. “Without flinching, Major replied, ‘7 percent’ — a number that established a major industry and persevered as the industry standard for several decades.” Asked later how he came up with it, Major answered: “A travel agent would have charged 10 percent.” — MAN p. 3.

5. Founding team and capital (accounts conflict — see §14)

• Mandell/Bloomingdale version: McNamara contributed Hamilton Credit and its $35,000 in uncollectable receivables; Bloomingdale put up $5,000 in cash — the only real money the company had. McNamara then borrowed $35,000 from the bank against it to get the enterprise off the ground. First-year ownership: McNamara 70%, Bloomingdale and Schneider 15% each. — MAN pp. 3–5.
• Simmons version: Schneider invested $10,000, McNamara $8,000; McNamara kept 90% of the stock “since he was going to run the whole thing.” Total original investment: $18,000. — SIM pp. 17, 23–24.
• First marketing was simple and cheap: leaflets slipped under office doors in the Empire State Building; the card was free and nobody’s credit was checked — applicants walked up to the office, and “if they looked trustworthy and claimed to have a job, they were given a card.” Ten or twelve restaurants around the Empire State Building signed up first. — MAN p. 4.
• First month of operation: $2,000 of business → $140 of revenue (7%). — MAN p. 4.

6. The first card and the first transaction

• The first card was a small piece of cardboard with “Diners Club” hand-drawn across one side “in roughly drawn script.” McNamara pitched: “One card. Many restaurants. One monthly bill.” — SIM p. 22.
• First transaction: lunch at Major’s Cabin Grill, February 1950 (Simmons dates the scene to 1950; the NYT ad in the blog already pins it to 8 Feb 1950). The waiter hesitated, then remembered the owner (Major Satz) had briefed the staff that morning; McNamara signed the three-part slip, added a sizable tip, and grinned: “Goddamn it! It worked!” — SIM pp. 16–17. This was, per Simmons, “the world’s first credit-card charge of its kind” — the first card issued by a third-party card company, honored at many establishments, producing a single monthly bill.
• Card numbers: #1000 McNamara, #1001 Schneider, #1002 Matty Simmons himself. — SIM p. 31.
• Schneider was six years older than McNamara, Harvard law degree, “small, dapper, deeply tanned, nose obviously broken somewhere along the way”; McNamara was 33, “pudgy with slick black hair and a pencil-thin mustache.” — SIM pp. 21–22.

7. The wallet story is a fabrication — who fabricated it

• Matty Simmons himself invented it. His actual exchange with McNamara: “When I asked McNamara how he thought of the idea, he smiled and said, ‘I just get ideas. I write them down and think about them for a while. Then I throw out the ones that don’t float. This one was never discarded.’ That wouldn’t do. I had to glamorize the creation of the credit-card plan…” So he wrote the stranded-without-cash, wife-driving- in-from-Long-Island version. “Of course, they couldn’t know until reading this that the scene never took place.” — SIM pp. 26–27.
• The legend lived on: in Life magazine’s 1990 “Most Important Americans of the Twentieth Century,” the picture of McNamara ran with “the fiction I’d created” — SIM p. 38. As Vanatta remarks, few have asked how a businessman who forgot his wallet would have remembered his Diners card — VAN p. 56.
• Earliest printed rendition E&S found: a Newsweek write-up two years after the launch (1952); one later journalist moved the credit to Bloomingdale and changed the meal to dinner. — E&S p. 54.
• By 1961 the industry already called the meal “The First Supper” — BLK p. 13.
• Earliest located NYT rendition (2 Dec 1956, Grutzner) prints the fabrication with a twist: not a Major’s dinner but a street-corner meeting — the client tells the lawyer: “‘Unfunny thing happened to me last night,’ the client remarked. ‘I had dinner at a restaurant over on the East Side and when I reached for my wallet—nothing… Waited an hour and a half while my wife drove in from Long Island to pay my check.’” Within two weeks “the pair of them launched The Diners’ Club.” The lawyer is named (Schneider, now chairman) but the businessman is given as Bloomingdale (now president) — McNamara is not mentioned at all, four years after his buyout. Post-1952 corporate memory had already started writing the founder out. — NYT, 2 Dec 1956, p. 26 (§21).
• There is even a second fabrication layer in circulation: the McNamara/Simmons encounter began with restaurant columnist Eddie Black recommending Simmons to McNamara (“this fellow had two problems: he didn’t know how to sell the plan… and had limited contacts in the restaurant industry”). — SIM pp. 20–21.

8. Launch numbers

• Recruitment: first week canvassed ten New York restaurants, all refused; by the end of the third week a dozen restaurants had joined. One hundred cardholders were gained by mailing a prospectus to 5,000 sales managers. — BLK pp. 12–13.
• Simmons’s version: a card was designed and sent unsolicited to several thousand prominent businessmen; Major’s was first (the founders ate lunch there daily); Simmons’s own PR clients — Chambord, Bagatelle, Embassy Club, Glucksterns, Jimmy Kelly’s — joined “albeit begrudgingly”; then Townley’s, the Prince George Hotel dining rooms, etc. — SIM pp. 22–23, 27.
• Schneider, a decade later: “Both MacNamara and I solicited business. It was rough sledding. Plenty of skepticism on the part of the establishments… They thought there had to be a catch.” — BLK pp. 12–13.
• Fall 1950: card honored in New York, Chicago, Boston, Philadelphia, Miami and Los Angeles; nearly 30,000 cardholders charging $250,000 a month; the company grossed $16,000+/month from its percentage — and was losing money (interest to factors + operating cost outran the discount). — SIM p. 28.
• First anniversary (Feb 1951): 42,000 cardholders; 330 restaurants, hotels and nightclubs (E&S p. 54); Vanatta puts it at “more than 40,000 members and 300 participating restaurants and nightclubs,” with offices in Boston, Hollywood and Chicago (VAN p. 56, citing LAT/WSJ pieces incl. WSJ 28 Mar 1951, “In the Red in 1st Year of Operation”).
• In March 1951 Diners Club handled $3 million of cardholder-merchant exchanges and reportedly made almost $60,000 in pretax profit — a $35.5M annual run-rate. — E&S p. 54. (Black instead recalls the second year: MacNamara and Schneider “plunged over $58,000 into debt” while charged goods and services topped $1 million — BLK p. 14.)
• Vintage NYT trajectory (primary — details in §21): ~200,000 cardholders on 150,000 accounts, >$3M/month, 4,000 establishments (Dec 1955) → 374,000 members after the Trip-Charge absorption, 9,000 establishments, $60M billings (Dec 1956) → 850,000 members, $93M a year, 20,000 establishments (Nov 1958), with the Sheraton deal set to take it to ~1.1M.

⚠️ Replaces the unsourced line at blog 944–946 (“By the end of 1950, Diners Club had 100% of the credit card business, with 20,000 customers, accepted at over 1000 restaurants”). No book in the set supports those exact figures; the “20,000 by end of 1950” figure only appears in unsourced modern writeups. Vintage alternatives: Time (1951) said 42,000 members by the first anniversary; a 1959 wire feature (Oregon Statesman, 24 May 1959) recalled “10,000 members charging at about a thousand establishments” within a year. Recommend the Time/E&S numbers (42,000 / 330) as best sourced — see §18.

9. Pricing: the discount, and why the membership fee saved the company

• Initial merchant deal: collect 100% from cardholder, reimburse restaurant at 94% → 6% discount; after the first two dozen or so establishments signed, McNamara raised the fee for all new signees to 7%. — SIM pp. 22, 28–29.
• The merchant rationale McNamara gave: someone charging food and drink spends more than with cash. Simmons’s mid-1950s survey quantified it: a Diners Club cardholder spent 18% more than a cash customer — the standing answer to the 7% complaint. — SIM pp. 22, 41.
• At first the card was free: “Nobody would pay to get a credit card,” McNamara insisted. After the 1950 losses, Simmons proposed charging; Schneider: “I have a hunch we’d lose the people who don’t use the card, but the people who do won’t mind paying a small fee.” A $3 membership fee was instituted; exactly as Schneider predicted, only the non-users dropped out. — SIM p. 29. Vanatta dates profitability from this fee: the company “lost more than $300,000 in its first year; the annual fee enabled the firm to turn a profit” — VAN p. 57.
• “The Diners Club was not to have another losing year for the next seventeen years.” — SIM p. 29. (Mandell: profitable for eighteen years until the Continental takeover, MAN pp. 6–7.)
• Fee ratchet: $5 by the late 1950s, plus $1 for the magazine; $2.50 for each “add-on” card (spouse/colleague on the same account); no penalty or interest charges for late payment within the 30-day billing cycle. — SIM p. 40; BLK p. 21 (1961: $5 join fee + $1 for the magazine).

  ⚠️ Vintage NYT pins the $5 fee earlier: already the going market rate in Aug 1953 (Rice) and explicitly Diners’ fee in Dec 1955 (McMahon), Dec 1956 and Nov 1958 (Grutzner) — see §21. So “late 1950s” is the insiders’ fuzzy memory; the fee was $5 from at least 1953. Amex entered in 1958 at $6 — a dollar above the incumbent.

10. Mechanics: billing, float, floor limits, hot lists

• The working-capital squeeze was structural: Diners had to pay merchants immediately while waiting for cardholders to settle — and unlike banks it could not fund itself with deposits; it borrowed in financial markets. — VAN p. 57. Factors were used in year one; first credit line from the small Sterling Bank, then larger banks competed to lend. — MAN p. 6.
• The float trick: with offices in NY and LA, New York bills were paid with checks drawn on the Los Angeles bank account, taking days to clear — “free credit for many years until,” per Bloomingdale, “one time a bank merged with helicopter and all my checks bounced.” — MAN p. 5.
• Restaurants gave Diners 30-day trade credit; cardholders got 30-day billing — up to a month of free float each way. — MAN pp. 5–6.
• No spending limits at first, no hot lists. With few establishments to police, they called and asked that a list of deadbeat cards be posted by the cash register; a card thief “never went to Joe’s Beanery, only to Romanoff’s,” so they’d call Romanoff’s and usually catch him. They hired their own detective. — MAN p. 6.
• By 1959–61 the controls resembled the modern ones: maximum charge without approval ~$100 (merchant phoned headquarters, collect); confidential blacklists of stolen/lost cards mailed to establishments — Diners’ typically ~200 names (Amex once 1,800, Carte Blanche 3,500 — too long to check, defeating themselves); Diners had a staff of twelve whose full-time job was physically picking up invalid cards. — BLK pp. 27–28.

11. The product: prestige first, convenience second, credit never

• McNamara’s own pitch to Simmons: receipts for reimbursement and tax deductions, no cash to carry, “but maybe most importantly, it’s prestige. It’s having a good enough credit rating to own one of these cards so that restaurants will treat you like somebody who’s somebody.” — SIM pp. 21–22.
• Company line (10th-anniversary press release, 1960): “The psychology of credit cards had a great deal to do with the success of The Diners’ Club. To charge is to attain a status and this has been an age of status… to have automatic credit wherever one goes has become a symbol of success.” — BLK p. 19.
• Black’s gloss, 1961: “only the needy carry cash… The man of means whips out a credit card, signs his name and no questions are asked.” — BLK p. 19.
• Vanatta on the sell: Diners repeated “charge it” in its advertising — “credit” never appeared. Convenience as status: “You don’t have to be a top executive to enjoy the many benefits of this man-about-town charge account privilege.” — VAN p. 57.
• Who the members were (Diners’ Club Magazine reader survey, fall 1959): >45% salesmen or corporation executives; the smallest group — clergymen and labor-union executives, 0.8% combined. Average member: married, 2.1 children, college graduate, 42½, $30,419 home, income $16,876 — three times the national average. — BLK pp. 19–20.
• Only two people ever received cards without a credit check: Harry S. Truman and U.S. Treasurer Ivy Baker Priest (given a solid-gold card as the 500,000th member; asked “What’s your bank?”, she replied: “Fort Knox.”). — BLK p. 21.
• The expense-account angle: an itemized monthly bill doubled as receipts for reimbursement and tax deduction (SIM p. 21); Time noted the “biggest advantage to business members” was a “ready-made accounting of their expenses for income-tax purposes” (VAN p. 57). By Dec 1959 the IRS was complaining publicly about blank expense allowances fueled by credit cards (Tax Commissioner Dana Latham, BLK pp. 17–18).
• Bookkeeping: 1961 fiscal-year commissions (~$9.7M) roughly covered the entire operating cost — including ~$1.4M for credit investigations and collections — so the $5 annual fee was nearly pure profit. Hence the membership treadmill. — BLK pp. 20–21.
• Customers wanted their signatures back: country-club billing — the original signed sales slips were mailed with the monthly bill. (The industry only abandoned it in 1973–76, when descriptive billing arrived.) — MAN intro p. xix & p. 62.

12. Growth, offices, magazine

• Staff: 3 besides McNamara at start of 1950 → 23 by year-end 1950; the company kept moving to bigger offices inside the Empire State Building (four moves in two years), then to two floors of the Coliseum at 10 Columbus Circle in the mid-1950s. — SIM pp. 29, 43.
• Spring 1951: membership over 100,000 — and nearly as many applicants had been rejected as poor credit risks. Credit losses ran ¼ of 1%; the largest tab any member had signed to that point: $496. — SIM p. 30.
• First non-restaurant expansion: the Henry Hudson Hotel let members charge rooms (no longer literally a “Diners” club); Budget Rent-a-Car became the first car-rental company to honor the card. — SIM pp. 30–31.
• The Diners Club Magazine: began as Simmons’s “Diners Club News” newsletter stuffed into billing envelopes; upgraded to a magazine; $1 added to the annual fee so it qualified for second-class postage (members had to check a box to opt out — over 90% “subscribed”). It became a negotiating chip (free ad pages to sign hotel chains), a shield against 7% grumbling, and for a while nearly as profitable as the card. Simmons wrote its restaurant column under the pen name “Franco Borghese”; a review would jam a restaurant for weeks. — SIM pp. 30–31,
  1. (Mandell p. 6 agrees: started because new restaurants accepting the card had to be publicized.)

13. War stories

• Blocked by the association? Start a restaurant. The Washington-state restaurant association had members agree not to accept Diners Club. Bloomingdale broke the boycott by opening his own restaurant in downtown Seattle — the only restaurant in town taking the card; card-holding businessmen flocked to it; the dependent downtown restaurants capitulated. — MAN pp. 8–9. (This sources the blog’s currently-uncited paragraph at line 991.)
• The Milwaukee/Seattle rate revolt (late 1950s): top restaurants in both cities organized to demand a discount cut, threatening mass exit. Simmons flew to Milwaukee, privately bought off leading restaurateurs with ad pages and cash advances, and at the association meeting — after a restaurateur swore he wouldn’t “pay this kind of money to make Alfred Bloomingdale even richer” — Mokey Friedman of Eugene’s Restaurant rose: “I’ve known Al Bloomingdale for years. I knew Al when he’d pay a thousand bucks just to watch two flies fuck. He doesn’t need our money. I’m not dropping out.” All but the two instigators stayed, at full rate; the Seattle revolt then “evaporated.” — SIM pp. 40–42.
• Buying the Stork Club: Sherman Billingsley refused the card for years (exclusivity). Asked what he needed — “I need money” — Simmons advanced him $50,000 against future Diners Club charges, and he signed. Toots Shor’s got the same deal. — SIM pp. 36–37.
• The bookie and the stolen card (mid-1950s): columnist Jimmy Breslin’s bookie friend “Fat Thomas” took a welshing gambler’s Diners Club card as payment of a ~$2,000 debt, ran up $6,000 in three days on dinners and chorus girls; the gambler reported the card stolen; Diners’ security men found Fat Thomas at a Long Island nightclub on his third steak, asked whether he was paying cash or card — “Charge it to my account, my man!” — and had him arrested. — SIM pp. 43–45.
• Playboy’s first national advertiser was Diners Club (mid-1950s; Victor Lownes approached Simmons; Schneider worried people would complain). — SIM pp. 42–43.
• Dine and Sign (Los Angeles): launched by Bloomingdale when his NY partners refused him a bigger stake — 25 restaurants, $150,000/month within three months. He mailed free cards to a bought list of Cadillac owners; signature on slips bore no resemblance to names, so he hired handwriting experts to match charge slips against voter-registration records. Lesson: “when a card was free, the issuer did not know who would use the card.” The two operations merged under the Diners Club name with a second billing office in LA and Bloomingdale as VP for western operations. — MAN pp. 4–6; SIM pp. 34–35.
• Other 1950s rivals: Trip-Charge of Chicago (85,000 cardholders and 9,000 merchants after a year, per a 1955 Newsweek piece; founder Sidney Rudolph’s motto: “Charge Everything Everywhere”); National Credit Card, Inc. (1951, forty-two states, bankrupt by 1954); the Esquire Club and Duncan Hines Signet Club (merged 1957); the Gourmet Guest Club; the hotel industry counter-attack, Universal Travelcard (1956, American Hotel Association; no merchant discount, $26 card fee — it skipped central billing, each hotel billed directly). — E&S pp. 54–55; SIM pp. 30–31; MAN p. 6.
• First airline signed: Western Airlines — resistance from airlines (which had their own card plan) was broken through Bloomingdale’s personal friendship with an airline officer. Bloomingdale was famously unable to sign Bloomingdale’s. Variable discount replaced Major’s flat 7%: airlines ~3% (big average ticket), later as low as 1%; restaurants stayed 7%. — MAN pp. 7–8.
• Fraud escalation, Miami Beach 1959 season: a stolen-card ring working the B-girl joints ran up $75,000–$100,000 in false bills — waiters picked pockets (sometimes with knockout drops); a pizza parlor billed $500 to a phantom customer; one nightclub billed $500 and added $400 “for a tip.” Diners absorbed merchant losses. — BLK pp. 26–27.
• Texas, May 1959: first credit-card-crime statute — up to $10,000 fine and 10 years; four states had such laws by 1961. — BLK p. 28.
• The 1957 Bortzfield publicity trip: a couple sent New York→New York around the world with no money, only a Diners Club card — 42 front-page articles in West Germany alone, met by the mayor of Paris. The campaign opened Europe. — BLK pp. 32–33.

14. McNamara’s exit (sources disagree — flag in footnote)

• By 1952 membership was 150,000; McNamara had put a personal ceiling on growth. — SIM p. 34.
• He sold out to Schneider and Bloomingdale:
  • SIM: mid-1952, his 50% for $500,000 (after an earlier cash-for-stock swap had turned the 90/10 split into 50/50). — SIM pp. 34–35.
  • MAN (from Bloomingdale’s interview): $250,000 for his 70%; the two buyers borrowed $125,000 each. — MAN p. 6.
  • BLK (1961): “for $200,000.” — BLK pp. 13–14. 👉 Recommend a footnote noting the three figures.
• His parting line to Simmons: “It’ll peter out at 250,000 members, last for a while, then disappear like the zoot suit.” — SIM p. 35.
• He put the money into a Pennsylvania housing development; the homes had inadequate water access and he lost it all. On 9 November 1957 he died of a heart attack, aged 40, broke. — SIM pp. 37–38. A year later membership passed 300,000; his original 90% would later have been worth roughly $50 million — one hundred times what he sold it for. — SIM p. 35.

15. Boom, plateau, decline

• 1953: Simmons joined full-time as EVP for sales & marketing and editor of the magazine. — SIM pp. 35–36.
• 1955: the company went public (VAN p. 56); membership 260,000 in April 1956; 560,000 by February 1958, billing $92 million a year. — VAN pp. 56–57.
• 1956: annual transaction volume >$290 million, 9,000 establishments “from Anchorage to Tahiti” (NYT). 1958: volume >$465 million, $40 million gross profit. — E&S p. 55.
• By decade’s end: 1 million+ members, NYSE-listed, ~$5M annual profit; early rivals absorbed or defunct. — SIM p. 37.
• FY ending March 31, 1960: billings $165 million, profit ~$2 million. — BLK p. 14.
• The monopoly lasted about seven years — American Express and Hilton’s Carte Blanche arrived in 1958. — MAN p. 9. (T&E monopoly-of-one framing: “Of the early major entrants, only Diners Club survived the decade” — E&S p. 56.)
• 1965: Chase Manhattan agreed to buy Diners Club for $56.6 million; the Justice Department blocked the deal on antitrust grounds (memo of intent Nov 1965; killed the following year). — MAN p. 9; VAN ch. on banks (pp. ~89–91 of ch. 4).
• Schneider died 1964; his shares passed to his family; Bloomingdale (unable to buy them himself) arranged Continental Insurance’s purchase; after boardroom war, Bloomingdale was forced to resign as head in 1969 (profits fell $2.4M in 1968 → $0.9M in 1969 under Amex and bank-card pressure); he got a “lifetime contract” so he wouldn’t join a competitor; Continental completed its takeover in 1970 (tender offer for the remaining two-thirds). — MAN pp. 9–10.
• Citibank bought Diners Club in 1981 (Mandell, writing 1990, says “1980”). — MAN p. 10; compare DOS name changes 1983/1986.
• American Express passed Diners Club to become the T&E volume leader in 1966; by 1970 Amex had twice Diners’ cardholders. — E&S pp. 58–59; MAN p. 22 (ch. 2).

16. International expansion (dates conflict across sources)

• Mandell: “in 1951 it went international,” selling franchises rather than offices (little capital); first three franchises sold outright, then the parent kept 25% of later ones. The first franchise — England — “literally came to them” (a British lecturer on the U.S. circuit asked; they only exchanged charges; eventually the U.S. parent owned “50 percent and one share”). — MAN p. 7.
• Simmons: France was first, 1955; traveling VP M. Mark Sulkes then sold franchises for every country outside the U.S. and Canada. — SIM p. 37.
• Vanatta: international ops began 1953 in Italy and France, by which time 100,000+ members and 3,000 merchants worldwide. — VAN p. 56.
• Black (1961): “Starting in 1953, Diners’ managed to set up more than forty-eight franchises covering more than one hundred countries and territories… Argentina, the Congo, Tahiti, Surinam and Zanzibar.” By spring 1960: 18,000+ foreign establishments; Sulkes claimed 100,000 members in Europe, 80,000 elsewhere; he’d cracked Yugoslavia and was negotiating with Bulgaria and Intourist. — BLK pp. 32–33. 👉 The franchise story anchors the India section later in the blog — pick one date (1953 has two sources) and note the variance if needed.

17. Good endnote material for the current section

• E&S’s framing of the two-sided pricing discovery: Diners “discovered a pricing strategy that got both merchants and cardholders on board,” kept ~70% of revenue from merchants — the template later card systems followed. — E&S pp. 54–55.
• Mandell’s obit for the founders (matches the blog’s current closing sentiment): “its relatively small place in today’s credit card marketplace gives little indication of its status as the pioneer of the modern credit card industry… their contributions have largely been forgotten.” — MAN p. 10.
• Spelling note: “Diners’ Club” is the original styling (apostrophe after the s). — VAN, note 43 (citing early ads: “Say ‘Charge It’,” NYT, Oct 10, 1950; “Indispensable New Convenience,” LAT, Dec 12, 1950). The blog header currently reads “Diner’s Club” — worth fixing.

18. Vintage press (primary) — found online

• Frank McNamara’s obituary, The New York Times, 11 Nov 1957: “Frank McNamara of Diners Club Dies; Built It Into $6 Million-a-Year Business.” Died 10 Nov 1957 of a heart attack at home in Shorehaven, Manhasset, L.I., aged 40; founded Diners Club 1950 with offices in the Empire State Building; “its president until 1952, when he left to become a sales executive for a lumber company.” The obituary already repeats the forgotten-wallet legend as fact. [nytimes.com/1957/11/11/archives]
• Ralph Schneider’s obituary, The New York Times, 3 Nov 1964: “Ralph E. Schneider Dead at 55; Diners’ Club Founder and Head; Lawyer Pursued Credit Idea With Client — Business Made Him Millionaire.”
• Time magazine, 1951 (exact issue TBD): “Unlike other mortals, the 42,000 members of the Diners’ Club need never pay the waiter when they wind up a spirited evening on the town. They simply sign the check, get billed once a month.” — quoted in Time’s own retrospective, 19 Oct 2016 (“Now You Know: What Was the First Credit Card?”). The same retro says first year: 42,000 cardholders; >$500,000 of transactions at 330 establishments in a single month; five years in, 300,000 members.
• Time, 22 Sep 1958 (“MODERN LIVING: Credit-Card Game”, Vol. LXXII No. 12): founders’ ages at founding-era — Schneider 49, Bloomingdale 42; Diners’ 750,000 members / 17,000 restaurants, hotels, motels and specialty shops; Amex had entered ~3 months earlier and mailed card applications to 8,000,000 bank depositors with President Ralph T. Reed personally writing 22,000 corporation presidents; Amex bought the Gourmet Guest Club (45,000 members); Diners retaliated by picking up the Esquire Club (100,000); Amex then bought the Universal Travelcard (160,000 members, 4,500 hotels). Costs: $7–10 to recruit a new member, $2.50–4 just to check an applicant’s credit; most of Diners’ profit came from the $5 annual fee; earned $1.29 a share in FY ended March 1958. Opening line: “Credit, which was once the sign that a person had trouble meeting his bills, has taken on a glamorous new meaning… a man with a credit card can rent a plane or boat or car, live it up in nightclubs, take a safari to Africa and even get a Kelly Girl for temporary office help.”
• The Oregon Statesman, 24 May 1959 (wire feature): “Within a year, Diners’ Club had 10,000 members charging at about a thousand establishments… The membership will pass the million mark in 1959, and participating establishments… now number about 20,000 in the United States and 76 other countries. It costs $5 a year to belong… the individual member spends an average of $20 a month. He also receives a subscription to the club’s magazine.” (Note: its year-one count — 10,000/1,000 — conflicts with Time/E&S 42,000/330. Pick one and footnote; E&S/Vanatta are the more rigorous.)

19. The Winsted “death of cash” stunt (13 March 1963)

• Matty Simmons, “The Day Cash Died,” Saturday Evening Post, 4 Apr 2016: Columbia Pictures marketing heads (Charlie Powell, Buddy Young) asked Simmons for a stunt to launch their Danny Kaye comedy “The Man From the Diners’ Club” (world premiere at the Strand Theater, Winsted). Simmons and brother Don proposed putting a whole town on credit cards for 24 hours. Cards were issued to everyone in Winsted, Connecticut — about 10,000 people; the day went off without a hitch: “groceries, taxis, clothing, everything. No problems — buy and sign.” At day’s end Schneider shook his hand: “This is it. This is the future.” — SEP, 2016.
• The town made it law for the day: the Board of Selectmen unanimously adopted an ordinance — “unlawful for any person to pay cash for any article or goods purchased and it shall be unlawful for any merchant to accept cash” — with junior cards for children, and penalties up to forfeiture of a vendor’s license or a day in the town stockade. Mayor John E. Lynch: “I am especially pleased to participate in this progressive experiment in the use of credit.” — Hartford Courant, 23 Oct 1962, quoted in David G. W. Birch’s Medium piece (4 May 2020).
• Simmons wrote a mock obituary printed on the front page of the Winsted Evening Citizen, 12 Mar 1963: “CASH DIED TODAY! … Cash, which was born several thousand years ago, the son of Barter, the adopted child of Trade, died today in Winsted, Connecticut… The Diners Club, one of cash’s most powerful adversaries since it was born in 1950, was appropriately enough the chief pallbearer at cash’s funeral today… The exact time of that death was 12:01 AM March 13th, Winsted time.” — SEP, 2016.
• Companion trivia: the 1963 feature film itself, and “The Diners’ Club Credit Card Game” — a board game by the Ideal Toy Corporation (per Diners Club’s official site).

20. Simmons obituaries & other retrospectives (secondary)

• Matty Simmons obituaries: died 29 Apr 2020, age 93 (NYT, 1 May 2020). His own précis: “The Diners Club begat Weight Watchers Magazine, which begat the National Lampoon, and that begat ‘Animal House.’” L.A. Times (2 May 2020): while EVP at Diners Club he hired blacklisted Hollywood writers for Signature, per his son Michael. Hollywood Reporter: he exited after the Continental Insurance acquisition and founded 21st Century Communications in 1967.
• L.A. Times, 12 Mar 2000 (“A Humble Start for Today’s Necessity”) / NYT “Credit Cards at 50” (same week): first card offered to 200 people, 14 Manhattan restaurants; by March 1951: 42,000 cards, 330+ businesses, membership $3 a year; Bloomingdale in a 1959 magazine interview: “Where will it end? I don’t see any limits. I think someday you’re going to be able to charge anything.”
• American Heritage, Nov 1991 (“Credit Card America”, Vol. 42/7): founded on Schneider’s $10,000; the 1958 Hollywood divorce settlement that spelled out who got custody of the couple’s Diners Club card; quotes Time 1958: “in the nation’s expense-account economy, nobody is anybody unless he can say, ‘Charge it.’”; the Bortzfields going “from New York to New York without a dime in their pockets” on TV’s The Big Program.
• Diners Club official history (dinersclub.com/about-us/history): Life’s “100 Most Influential Americans of the 20th Century” for McNamara; an AMA International panel calling the card one of the “75 greatest management decisions ever made”; a multimillion-dollar business-traveler campaign: “You can drop our name where it counts.”
• EBSCO Research Starter (“Diners Club Begins a New Industry”): “In 1952, after two full years of operation, Diners Club showed a profit of $61,222 on sales of $6.2 million.”
• ⚠️ Evans & Schmalensee cross-edition drift (their own numbers moved between the 2004 1st and 2005 2nd editions): start-up capital $1.8M → $1.5M; first-anniversary fee $21 → $18/year; March 1951 handled $3.5M → $3.0M and pretax $70k → $60k; 1957 card fee $30 → $26. And both editions conflict with Simmons and the LAT/NYT (which say $3 a year). Where they conflict, trust the insiders and the vintage press.
• ⚠️ Simmons’s 2016 SEP piece also contradicts his own 1995 memoir on early numbers (“8,000 cardholders within weeks [of the BusinessWeek piece]… by the end of the year, membership was near 100,000” vs. 1995: ~30,000 by fall 1950, 100,000 by spring 1951). Prefer the book.

21. Vintage NYT primary sources (user-provided scans, 1953–1958)

Five NYT clippings from books_papers/newspapers/diners_club. Page numbers as encoded in the scan filenames.

• 2 Aug 1953, p. 19 — “Charge-Account Vacations Gain Favor” (Diana Rice, travel column). Credit-card plans as travel tools; market fees: “$5 a year or … 50 cents for each month in which the credit card is used.” Lists Trip Charge, Go Europe ‘n’ Sign (>500 European hotels/restaurants), Tourex, and “the Diners’ Club, 350 Fifth Avenue” — i.e., the club ran out of the Empire State Building, matching the Major’s-adjacency lore.
• 4 Jun 1953, p. 50 — short business brief on a Diners’ Club study of who charges entertainment: advertising-agency executives lead average spending, then PR agents, manufacturers’ reps/distributors, theatrical booking agents, wholesalers’ reps; space salesmen 7th; retailers far down; doctors last. The ad industry alone = 21% of Diners’ Club’s total billing; PR = 9%. Club “operates nationally” as of mid-1953.
• 3 Dec 1955, p. 27 — “MODERN VEHICLE OF TRAVEL: A CARD” (J. E. McMahon). Numbers: ~200,000 cardholders on 150,000 accounts; more than $3,000,000 of business a month; 4,000 establishments (restaurants, hotels, florists, liquor shops, auto rental, airlines, gift marts) “here and abroad”; $5/yr membership. Collections behavior: about half of bills settled in the first half of the month, +35% by month-end, “the rest run for a longer period.” Competitor snapshot: Trip Charge ($5/yr), American Hotel Credit Corp., Gourmet’s Guest Club (900 restaurants), Duncan Hines Signet Club (1,500 establishments), Universal Air Travel Plan, Go Europe ‘N Sign, Rail Travel Credit Agency, Hertz (900 offices / 630 cities).
• 2 Dec 1956, p. 26 — “LIVING HIGH WITHOUT MONEY” (Charles Grutzner). Numbers: 374,000 members after absorbing Trip-Charge, Inc.; 9,000 establishments “from Anchorage to Tahiti”; $60,000,000 of billings in the last year; $5/yr member fee; 7% from hotels, restaurants and night clubs, 10% from other establishments. AHA’s Universal Travelcard (live since July 1956) already had 90,000 users at $5/yr across 4,400 hotels + the National Restaurant Association’s 60,000 eating places + Hertz/Avis/National: “a tug of war for many of the world’s eating places seems to be shaping up.” Air Travel Card: 94 airlines, 500,000+ North American users (+200,000 abroad), ~$450 deposit, ATA estimate of 25% of all U.S. air travel on credit cards. Includes the “Reluctant Spouse” anecdote (husband asks to cancel his wife’s card, then panics: “Look, lady, don’t get me in the middle!”). See §7 for this article’s origin-story retelling.
• 2 Nov 1958, pp. 1, 12 — “ALL OVER THE GLOBE—ON CREDIT” (Charles Grutzner): the Amex–Diners showdown. Diners: 850,000 members, $93,000,000 a year, 20,000 establishments; a Sheraton Central Credit Corp. agreement (~50 Sheraton hotels, incl. the Sheraton East/former Ambassador and McAlpin in NY and the Blackstone in Chicago) expected to push membership “to 1,100,000”; DC had earlier absorbed the Esquire Club, which brought it 100,000 members. American Express announced its card June 1958 “with a great fanfare of publicity” and went live 1 Oct 1958 at $6/yr; bought Gourmet Guest Club (+45,000 members) and took over the Universal Travelcard (160,000 subscribers) — the very card the AHA had built “in opposition to the Diners’ Club.” Travel-agent terms: Diners charged agents a $500 annual franchise fee + 4% discount off their commissions (letting them keep the $5 new-member fee, dangling “$100,000,000 additional travel business”); Amex: 2% on transportation only, $2 per new member. ASTA’s ad hoc committee advised agents to “refrain from entering into any credit card agreement” and mulled its own card; 100+ agents had signed with Diners anyway. The International Hotel Association had a ban on credit cards at deluxe European hotels. Airlines refused to honor either card (protecting their own Air Travel Card: $425 deposit, 95 airlines).

Takeaways for the blog:

• Fee timeline pinned from vintage press: $3/yr (Mar 1951, Time) → $5/yr by Aug 1953 (NYT), still $5 in Dec 1955, Dec 1956 and Nov 1958. So Simmons/Black’s “$5 by the late 1950s” (§9) is low — it was $5 by 1953.
• Membership trajectory, primary-sourced: 42,000 (Mar 1951) → 200,000 cardholders/150,000 accounts (Dec 1955) → 374,000 (Dec 1956, post Trip-Charge) → 850,000 (Nov 1958) → ~1.1M on the Sheraton deal → NYSE listing 1959 (company timeline).
• Volume trajectory: $3M+/month (Dec 1955) → $60M/yr (1956) → $93M/yr (1958).
• The 1956 Grutzner piece is the earliest located NYT origin retelling — and it already erases McNamara (post-buyout) while printing the Simmons-invented Long Island detail.
• Amex entry parameters (announced June 1958, live 1 Oct 1958, $6/yr) are now primary-sourced — useful for the blog’s Amex pivot.
• The June 1953 ad-exec spending study is a lovely color detail for the expense-account-economy theme (admen = 21% of all billings by 1953).

22. Provenance trace: “8 February 1950” is not primary — and the eyewitness said the 9th

The exact-day claim has no contemporaneous primary source. What the record actually shows:

• Insiders/near-contemporaries give no exact day: Simmons’s 1995 memoir says only “this February day”; Schneider (via Black, 1961): “one February night in 1950”; Time (1951) and both NYT obits: no day. The company’s own timeline said only “February 1950” — still does on the current page and in the Dec 2021 Wayback capture of dinersclub.com/about-us/history.
• The one participant who ever gave an exact day said the 9th. Simmons, in his 2016 Saturday Evening Post piece: “On February 9, 1950, there were three [cards]… Card 1000 was first used when the three of us had lunch that day.” The only eyewitness date on record is 9 Feb 1950.
• “Feb 8” is back-formed lore. Earliest print instance located: The Globe and Mail, ~25–26 Nov 2009 (“Feb. 8, 1950: The first Diners Club charge is made at Major’s Cabin Grill”). Wikipedia carried the sentence “The first credit card charge was made on February 8, 1950, by Frank McNamara, Ralph Schneider and Matty Simmons at Major’s Cabin Grill” by Feb 2012 (quoted by historyofinformation.com, accessed 28 Feb 2012) — before every book now cited for it. Quentin Skrabec’s encyclopedia The 100 Most Significant Events in American Business (ABC-CLIO, 2012), p. 186 repeats the Wikipedia sentence verbatim. Wikipedia’s current footnote points to Roberts & Berg, Walmart: Key Insights (Kogan Page, 2012), p. 8 — a retail-management book with no Diners Club provenance. A restaurant-history blog (restaurant-ingthroughhistory.com, 3 Jun 2013) and Jeffrey Robinson’s unsourced LinkedIn essay (2020: “Wednesday, February 8, 1950” — the 8th was indeed a Wednesday) round out the chain.
• The company only recently canonized the 8th: 75th-anniversary copy (2025) — e.g., the Forbes BrandVoice piece “Diners Club International Celebrates 75 Years” (14 Feb 2025) and mirrored anniversary text — asserts: “On February 8, 1950, they return to Major’s Cabin Grill…”
• Recommendation: write “early February 1950” (fully defensible), or if the exact day is wanted for color, footnote it as contested: company tradition says 8 Feb; its own long-standing timeline and every insider said only “February 1950,” and Simmons’s dated retelling says the 9th.
