Lenaerts Correspondence and other LEO papers (Manchester photocopies)


File of photocopies of the Ernest Lenaerts papers held at the University of Manchester Library  (formerly GB 133 NAHC/LEO/B18).

These papers were evidently selected for photocopying then sorted and numbered by Peter Bird as part of his research for his book LEO - The First Business Computer  (Wokingham: Hasler, 1994).

They contain copies of only parts of the Lenaerts papers held at Manchester (GB 133 EHL), specifically:
EHL/1  Cambridge-Cadby Correspondence. Letters written by Ernest Lenaerts to Lyons managers John Simmons, T.R. Thompson and W.J. Edwards (with replies) during Lenaerts' secondment to the Cambridge University Mathematical Laboratory, working as part of the EDSAC team under Maurice Wilkes, 1944-1949;
EHL/5  Report by Lenaerts: Possible Improvements to Mercury Delay Storage, 1953; 
EHL/9  Field report by Lenaerts on the Samastronic printer, 1962; 
EHL/14 (part)  Later correspondence between Ernest Lenaerts and Peter Bird, 1988-1992; 
EHL/16 (part)  Revolution by Numbers.  Draft of chapter 4 of a monograph on computers by Ernest Lenaerts, 1971.
