LEO - Lyons Electronic Office - the world's first business computer was built and operated near here by J Lyons & Co.
Erected by LEO Computers Society 2016
www.LEO-computers.org.uk

Here's the video of the unveiling timed to commemorate 65 years of LEO. We believe the computer work took place in Kaevener House, on the Cadby Hall site.

Site: J. Lyons and Cadby Hall (3 memorials)

W14, Hammersmith Road, Lyons Walk

At this address: Cadby Hall, Hammersmith Road, Lyons had a huge site, with its head office, several bakeries, and an ice cream factory. This was all demolished in 1983.

The Lyons Walk plaque is at the centre of a circle of trees and empty tree pits (indicating lost trees). The LEO plaque is horizontal, at the centre of the middle of the 3 new, raised, red brick flower beds.
