CMLEO/EL - Ernest Lenaerts Collection
Digital and hard copy surrogates of material created by Lyons engineer Ernest Lenaerts
(1910-1997) during his work on the LEO computer.
The notebooks he kept during his engineering work on LEO I are believed to be the only surviving contemporary written account of the installation and development of the computer at Cadby Hall in the early 1950s.
Provenance: Materials have been collected by the Centre for Computing History from multiple sources, and added to the LEO Archive.
Some records are available now but please be aware that scanning and cataloguing of the collection is ongoing.
