Lyons Electronic Office: The Story of the World’s First Business Computer
To mark the 70th anniversary of LEO, the world’s first business computer, the LEO Computers Society and the Centre for Computing History (CCH) are launching a new specially commissioned short film. Funded by the National Lottery Heritage Fund as part of efforts to preserve and promote the history of this remarkable British invention, the film will be released on the 30th November – the day in 1951 that LEO ran its first program. The film will introduce a whole new generation, from secondary school age upwards, to the remarkable story of the birth of computing technology that, today, we take for granted.
The film will premiere on YouTube at 7pm on 30th November 2021 at https://youtu.be/Rzu68nRVwtE.

September 1951 – At J. Lyons & Co on Wednesday, 5th September 1951 the Bakery Valuations programme was run to completion on real data as an experiment to test the hardware. As noted in Ernest Lenaerts notebook for that date it ran from 3:50 to 5:35 without a fault and was the longest run of any programme at that time.

We are organizing a new series of Zoom Meetings.
See Below
Wednesday Online celebrations!
During the past year we have discovered that online forums and presentations have been a great way to get our members together. Zoom has allowed former colleagues, now living in different continents to reminisce together and for, 22nd September 17.00 BST AGM including updates on all our activities and a vote for Trustees. This will be followed by a discussion among members on ideas for the future.
Tuesday, 19th October 10.30 BST We hope to bring you a tour of The National Museum of Computing at Bletchley Park. As many of you will know, TNMoC has a reconstruction of EDSAC, the computer built at Cambridge which Lyons helped to fund so that they could develop a commercial computer for themselves.
Wednesday, 17th November 15.00 GMT Our new LEO Film! By this date in 1951, LEO was almost ready to run its first regular clerical run working on the Lyons Bakery Valuations Job. As part of our National Lottery Heritage Fund programme, we have had a 15 minute film made about LEO. This will be given its press launch in late November to chime with the actual anniversary itself, but we have managed to arrange for our members to be given an exclusive pre-launch viewing. The film will be followed by an opportunity for members to comment and for a discussion with the filmmakers.
