June 27, 2024"It was the first evidence to me that we'd changed the world." — John Shepherd-Barron ↓ ↓ ↓ ↓ ↓ ↓ Hey look, a chance to support the newsletter!
Please let me know here if you can't see the ads. Thanks! ↑ ↑ ↑ ↑ ↑ ↑ Come and see me on Monday morningDuring World War II, a teenager named John Shepherd-Barron joined the British Army, where he was eventually assigned to an elite unit called the 159th Parachute Light Regiment, and nicknamed the Chindits. These were special operations units that conducted long-range patrols during the Burma Campaign. It was dangerous work, but it made sense that Shepherd-Barron wound up there, since he'd been born and raised in India before going to England for school. There are probably some pretty amazing stories of Shepherd-Barron's time in the military, but for our purposes, we're just going to point out one thing. It's that like all soldiers, Shepherd-Barron was given a service number, and he repeated it so many times in uniform that he could rattle it off many years later. Hold onto that for a minute. After the war was over, Shepherd-Barron came home to the U.K., where he wound up in the management trainee program at a company called De La Rue Instruments. He worked hard, drew a paycheck, and formed a habit of cashing the check each Friday at the same time. Then, one Friday in 1965, he was delayed, and he arrived at the bank one minute after it closed. Stuck without cash for the weekend, he went home, drew a bath, and contemplated his dilemma. "It struck me there must be a way I could get my own money, anywhere in the world or the UK," he recalled long afterward. "I hit upon the idea of a chocolate bar dispenser, but replacing chocolate with cash." Yes, John Shepherd-Barron is the person credited with inventing the automated teller machine, or ATM, which debuted 57 years ago today in England -- long before it hit the United States, by the way. What's wild is that Shepherd-Barron wasn't in the banking industry or an accomplished inventor. But, a few months after his bathtub epiphany, he arranged to run into the chief general manager of Barclay's Bank. The Telegraph picked up the story here, after Shepherd-Barron's death in 2010: Over a pink gin, Shepherd-Barron asked him for 90 seconds to pitch his idea for a cash machine.
I told him I had an idea that if you put your standard Barclays cheque through a slot in the side of the bank, it will deliver standard amounts of money around the clock.
He said, 'Come and see me on Monday morning.'"
Barclays commissioned Shepherd-Barron to build six cash dispensers, the first of which was installed at a branch in the north London suburb of Enfield on June 27, 1967. Remember I said to hold onto the fact that he held onto his military service number? This is what gave him the idea for ATMs to use PINs -- personal identification numbers. Shepherd-Barron initially intended for every ATM user to have a 6-digit PIN, but his wife convinced him that would be too many digits. "Over the kitchen table, she said she could only remember four figures, so because of her, four figures became the world standard," he recalled. Sadly, this is apparently another instance of someone inventing something incredibly useful but never getting much in the way of financial reward as a result. However, he received all kinds of honors for his work, and he apparently lived a long and happy life. And for that reason, I think we'll end with a quote from him about when he realized the reach of what he'd created. It came years later when he was visiting Thailand, and he watched a farmer roll up to an ATM on an ox-driven cart, remove his wide-brimmed hat, and withdraw cash: "It was the first evidence to me that we'd changed the world."
The winner of our "name the debate poll?" As of 1:15 p.m. Wednesday, as I wrote this we had 418 votes, and it turns out we have a landslide victory:
Actually, I'd say "Other" was the real second-place winner. The vast majority of those email replies were suggestions that I shouldn't make fun of the debate because this is a crucial election and only [XXXXX] can save the country from ruin. The "XXXXX" was for "Trump" in many reader emails, and "Biden" in others. I'm not going to tally those; I think you all can probably guess who I support, but I try not to hit everyone over the head with it. At the least I think our polling here suggests the vast majority of Americans wish there were other choices. Folks, next week includes the Fourth of July, and I'm going to take some vacation starting tomorrow. When we return during the week of July 8, I hope we'll be revamping and reintroducing both Big Optimism and Understandably. Thanks for being with us! Know someone who might like this newsletter?
