Scope and Content
Administrative / Biographical History
Collaborations between J. Lyons & Company, a British catering company with strong interests in new office management techniques, and Cambridge University led to the production of a series of important computers, called LEO - Lyons Electronic Office. LEO, operational in 1951, ran "the world's first regular routine office computer job". LEO Computers Ltd was formed in 1954 with Anthony Salmon, J.R.M. Simmons and T.R. Thompson as Directors. The company installed LEO computers in many British offices, including Ford Motor Company and the "clerical factory" of the Ministry of Pensions at Newcastle. LEO Computers Ltd merged with the computer interests of English Electric in 1963 to form English Electric LEO. Subsequent mergers eventually found LEO incorporated into ICL in 1968.
