Seminar on Films about LEO

Time/Date December 17th at 14:00

Speaker Dan Hayton et al

Location Via Zoom

Each year the CCS looks for a selection of films and videos relating to the History of Computing. This year, following on from the October’s lecture “The Evolution of LEO, the World’s First Business Computer” we’re taking a look at LEO on film. 

This year’s programme gives us a chance to see how others and ourselves in the computer industry view and depict our chosen work environment. We’re grateful to the Computer History Archive for permission to use two of their “reels”. We have “gleaned” other items from public sources. Thanks too to Peter Byford of the LEO Society for suggesting, encouraging (and chasing me up) on the theme of this year’s show. 

About the speaker
Dan Hayton is the CCS’s media manager and is usually to be found at the back of the room with a video camera. Once a year we release him from this duty and allow him to take centre stage – partly because he has earned a rest from his normal duties, but mostly because he is an entertaining raconteur who delights his audience. Apart from his role in the CCS he is also a leading member of the Newcomen Society and of the Greater London Industrial Archaeology Society. A man of many talents, not to be missed.
