 At the peak of the Lyons operations, the entire stretch of land along the Hammersmith Road between Blythe Road and Brook Green became one vast manufacturing enclosure with over 30,000 staff working 24 hours a day, 365 days a year.The name of Cadby Hall became so synonymous with the company that the three later overseas J. Lyons & Co. complexes in Toronto, Canada; Natal, South Africa, and Salisbury, Rhodesia (today Harare, Zimbabwe) were also named Cadby Hall.The original Cadby Hall site in Hammersmith also earned a place in history as the birthplace of the first ever business computer, LEO, which Lyons developed between 1949-1951 to automate its clerical and administrative tasks.
