60495 Ernest Lenaerts looking at a LEO I teleprinter

Description of Photograph

Photograph of Ernest Lenaerts at work on LEO I at Cadby Hall.
(Kept with a second copy of the same photograph, slightly cropped at the bottom).


Research comments: Ernest Lenaerts was one of the key members of the LEO I team. In this photograph he is looking at a teleprinter adapted for 5 wire operations. Lenaerts, initially based at Cambridge with the EDSAC machine, worked with John Pinkerton on plans for building LEO and they, together with Ernest Kaye and Ray Shaw, were responsible for most of the circuit development for the calculator. This is an early photo, likely taken c1950. The valve racks in front of Lenaerts are quite undeveloped. (CM/LM)

Collected by Peter Bird as part of his research for his book LEO - The First Business Computer (1994).
