Passage: The first commercial business computer was developed in the United Kingdom in 1951, by the J. Lyons and Co. catering organization. This was known as the 'Lyons Electronic Office' – or LEO for short. It was developed further and used widely during the 1960s and early 1970s. (Lyons formed a separate company to develop the LEO computers and this subsequently merged to form English Electric Leo Marconi and then International Computers Limited.)
