Join CCH and the LEO Computers Society as we celebrate the 75th anniversary of LEO (Lyons Electronic Office), the world's first business computer.
Discover why LEO transformed how businesses operated, and how it played a key role on the journey to the digital world of today.
The day will feature family-friendly activities, interactive exhibits, children's workshops, historical displays, and opportunities to meet members of the LEO Computers Society. Come and check out our special LEO@75 exhibition and learn how computing has evolved from LEO to today's AI technologies.
To bring the 1950s to life, the museum foyer will be transformed into a Lyons Tea Shop complete with tea, cakes and costumed Nippy waitresses, with two dance performances by the East Anglia Swing Troupe.
Thanks to funding from the AIT Trust, we are able to offer discounted family tickets to this event.
