This picture is one of the set taken by/for Tommy Thomas (far right in the above picture) in June 1998, shown on his website. It is copied here with his kind permission.
This shows an enhanced Manchester Mark 1 team standing in front of the Replica in the 1830 Warehouse: Left to Right: G.C. (Geoff) Tootill, D.B.G. (Dai) Edwards, Tom Kilburn, Laurie Allard, A.A. (Alec) Robinson, J.C. (Cliff) West, and G.E. ("Tommy") Thomas.
This picture was taken after the official
Handover Ceremony on the actual 50th
Anniversary day, when the Computer
Conservation Society formally handed over the Replica Baby to the
Museum of Science and Industry in
Manchester. Note that although the only person missing from the original
engineering team was
Professor Freddie Williams, we did at least have his
son present, Professor Fred Williams of Cardiff University, who looks very much
like his father (and according to Tom has much of his mannerisms as well)!
