LEO

British company J. Lyons and Co. builds and operates the world's first business computer, the Lyons Electronic Office (LEO), in the early 1950s. Lyons works with a team of engineers at Cambridge University to develop and deploy LEO. In 1953, LEO begins processing payroll for J. Lyons. The company will eventually produce the LEO II and LEO III and sell the computers commercially through the 1960s.
