October 8 in business history: a $2 bonus, a mall without a neighbourhood, and the first bank card

Three dates on 8 October — Raytheon's microwave patent in 1945, the first enclosed shopping centre in the United States in 1956, and the largest bank failure of its time in 1974 — each separate the act of invention from the ownership of what it turned out to be worth.

Three 8 Octobers, and each one separates the act of invention from the ownership of what it turned out to be worth: a patent that paid its inventor two dollars, a mall its architect disowned, and a bank card that outlived its bank.

The oven that had to buy a shop

On 8 October 1945 Raytheon filed a patent for cooking with microwaves 1. The idea came out of radar. Percy Spencer ran Raytheon's power-tube division, where he had raised magnetron output from about 100 a day to 2,600 for the war effort, and Raytheon paid him a one-time $2 bonus for the patent — the token sum it gave every employee inventor — with no royalty attached 2.

Building the oven was the easy part. Raytheon's 1947 Radarange cost between $2,000 and $3,000 and went mostly to commercial kitchens 3. The first consumer model, $1,300 in 1955, came from the Tappan Stove Company under licence 3. What Raytheon needed next was a dealer network, so in 1965 it bought Amana Refrigerators and in 1967 reached the countertop at $495 3.

Decision mirror: Raytheon held the patent and still had to buy its way to the customer. In 1997 it sold the appliance business for $550 million and went back to defence 4. The oven carried on without the company: a quarter of American households had one by 1986, and more than 90 per cent do now 3.

A mall the architect disowned

Southdale Center opened in Edina, Minnesota, on 8 October 1956, the first fully enclosed, climate-controlled shopping centre in the United States 5. The Dayton Company paid for it and Victor Gruen, a Viennese émigré, designed it: about $20 million, 72 stores, two department-store anchors, 5,200 parking spaces 6. More than 40,000 people came on the opening morning and another 188,000 in the week that followed 6.

Gruen drew a town square with shops around it — a garden court under a skylight, with a fishpond, trees and a café — on a site meant to carry a medical centre, schools and housing as well 6. Only the retail was built, and the building became an archetype: two levels, blank outside walls, all the activity turned inward 7.

Decision mirror: Other developers copied the building and skipped the town. In a speech in London in 1978, Gruen said malls had been disfigured by "the ugliness and discomfort of the land-wasting seas of parking", and that he refused "to pay alimony for those bastard developments" 7. Southdale sold for $125 million in 1997, and Simon Property Group now owns it, adding the parts Gruen drew — apartments from 2014, a hotel in 2018 — while a public library branch planned for an empty anchor in 2019 was dropped the year after 6.

The bank card that outlived the bank

Franklin National Bank started in 1926 in Franklin Square, Long Island, and by the 1950s it was the industry's experimenter: junior savings accounts, a drive-up teller window, and, early in the decade, the first general-purpose credit card issued by a bank 8. By 1974 it was the twentieth-largest bank in the country 9.

On 8 October 1974 Franklin was declared insolvent — the largest bank failure in American banking history to that date — and taken over by the European-American Bank and Trust Company, owned by six of Europe's largest banks 10. It had lost $63 million in the first five months of the year 9. The Federal Reserve lent it as much as $1.7 billion, and the New York Fed took its foreign-exchange portfolio onto its own books 11.

Decision mirror: A controlling shareholder's currency bets, not the card, decided the bank's fate 8. The bank card it pioneered became a category that now belongs to companies Franklin had nothing to do with: Visa alone is worth about $699 billion as of October 2026 12. The branches survived better than the bank, passing to European-American Bank and then to Citigroup 8.

Three questions for the day

Who owns the step between you and the customer? Raytheon held the patent and still had to buy a dealer network to reach a kitchen 3.
Who funds the part of the plan that repays slowly? Southdale's shops opened in 1956, its apartments arrived in 2014, and its library never came 6.
If the asset you invented moves elsewhere, what are you left holding? Franklin kept a currency book; the card's value went to the networks 12.
