LEO Computers commemorative plaque unveiled


Commemorative plinth unveiled in Lyons Walk in the Borough of Hammersmith and Fulham, London, a site overlooking the place once occupied by Cadby Hall, the headquarters of J. Lyons & Co and the location of the world’s first business computer LEO. 

The unveiling took place exactly 65 years after LEO carried out, on behalf of Lyons, the running of the world’s first data processing application on an electronic computer. The unveiling was carried out jointly by Dame Stephanie Shirley and Frank Land in the presence of representatives of the Borough of Hammersmith and Fulham, representatives of the local MP, Andrew Slaughter, descendants of the families which had built J. Lyons & Co., members of the LEO Computers Society and friends of LEO including representatives of the Association for Information Technology. The erection of the plinth was arranged by the Borough of Hammersmith and Fulham and much of the funding provided by Tony Morgan of the LEO Computers Society.
