We hate 2020!

Just when we thought 2020 couldn't get any worse! We were about to re-open after many months of being closed but then disaster struck when a mains water pipe burst and flooded much of the ground floor of the museum.
Sadly re-opening has now been postponed. Read More >>>

No visitors, no workshops, no events, no school visits... no income. We know that things are tough for everyone right now, but if you can afford to help us through these tough times please donate what you can.

There's over 36,000 exhibits here! That should keep you occupied for a bit - get searching!

Or come and get involved on our social media channels ...

Thank you.

CMLEO/EL - Ernest Lenaerts Collection

Description: 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 sample records are available now but please be aware that cataloguing of the collection is ongoing.
