On this date sixty years ago, September 5 1951, the world's first business computing program was first tested on the world's first business computer, the Lyons Electronic Office (link).
LEO was inspired by wartime computers that calculated things like artillery aiming tables for the military. Lyons was a massive restaurant chain in the UK, and realized that the new digital computers could simplify its human-driven accounting operations. So it built its own computer, consisting of 21 racks with 6,000 vacuum tubes and occupying about 5,000 square feet. The company's first use of LEO was to calculate the cost of all the baked goods produced by its 12 bakeries (link).
From that humble beginning...wait, that wasn't a humble beginning at all, it was a very cool beginning. The first use of a business computer was to solve a real-world problem faster and more accurately than people could do it on their own. That's exactly what you're supposed to do with computers. LEO was quickly adapted to other tasks, where it achieved impressive results. For example, it cut the time needed to calculate an employee paycheck from eight minutes to 1.5 seconds.
It's hard to believe that many people believed for years that computers didn't increase business productivity (link).
From that very auspicious start grew most of the computing industry we know today (link). So take a moment to contemplate that dinner roll or slice of pie you eat today, and say a quiet thank-you to David Caminer, John Pinkerton (link), and the other pioneers who got it all started sixty years ago today.
