LEO Catalogue Update: 27th January 2021

28th January 2021

Since the previous update, the following has been scanned, catalogued and uploaded:

From Peter Bird's Research Collection: LEO Computers Ltd, Company Secretary's Papers, part 2

As reported in November's entry, I have now begun scanning and listing the LEO Computers administrative papers collected by Peter Bird. I have now added the following files to our online catalogue:

Foxed by foolscap..

The file continues into the mid-1960s, but unfortunately at this point Lyons evidently opted to switch to foolscap-sized office paper, and this means, as I am unable to currently access an A3 scanner (thanks to the pandemic), I will have to finish the file at a later date. Watch this space!!


Ernest Lenaerts LEO Correspondence and other papers (Manchester photocopies)

The project has been very fortunate to inherit a set of photocopies of some of the papers kept by founding LEO engineer Ernest Lenaerts, selected from original archive material donated by him to the National Archive of Historical Computing (as was) held at the University of Manchester Library. (You can see the originals catalogued by Manchester on the Archives Hub - ref. GB 133 EHL, although digital copies are not yet available there). They include a very interesting run of correspondence between Lenaerts and John Simmons (and others) at Cadby Hall while he was on secondment to the EDSAC team at Cambridge.

Apparently this set of photocopies was made at the request of LEO historian Peter Bird, whose research collection (see above) forms a significant part of the LEO Computers Society archive. The copies were sorted and numbered by Peter Bird, and I have kept the order he established while listing and scanning them. We are very grateful for the assistance of University of Manchester Archivist James Peters for facilitating the transfer of these papers to the LEO Computers Society archive.


Note: It is important to make it clear that Lenaerts' detailed reports/notes from Cambridge, often referred to as enclosures within these letters, were not actually included in the run of photocopies for some reason. The originals no doubt remain with the Lenaerts papers at Manchester, ref. GB 133 EHL/2 EDSAC.

    • 62888 Lenaerts post-war work for Lyons, 1944-1945
      • Lenaerts was recruited to return to Lyons after his time in the RAF during WWII. This file includes the first letter from Lyons Company Secretary George Booth to Lenaerts (dated 1st September 1944 - see pictured), the text of which was probably a template for inviting back ('when victory is won') many previous employees who had gained valuable experience during the war.
