62816 Lenaerts-Cadby Hall correspondence


Photocopies of correspondence between Ernest Lenaerts and various managers at J. Lyons & Co, Cadby Hall, including a significant run of letters to and from John Simmons, T.R. Thompson and W.J. Edwards during Lenaerts' secondment to the Cambridge University Mathematical Laboratory, working as part of the EDSAC team under Maurice Wilkes.

Many of Lenaerts' original letters were written enclosing reports on the progress of the EDSAC team, but photocopies of the reports themselves were not included in this file.  Presumably the original reports are included in the archive copy held at Manchester, ref. GB 133 EHL/2 EDSAC.

Dates: 1944-1949

Archive Reference: CMLEO/EL/CW/1

Location of Originals: The original correspondence is still held in the archive collections of the University of Manchester Library, ref: GB 133 EHL/1.

Provenance: The photocopies were originally requested by Peter Bird, as part of his research for LEO - The First Business Computer, and later donated to the NAHC at Manchester, then transferred to CCH at the request of the LEO Computers Society for inclusion in their archive.
