TNMOC interviewed Captain Jerry Roberts MBE, a founder member of the codebreaking Testery at Bletchley Park during World War II, to record his memories of his work. Here he recalls Tommy Flowers, Bill Tutte and Alan Turing. The Colossus and Tunny galleries are open daily at TNMOC, the rest of the Museum is open to the general public at specific times: http://www.tnmoc.org/visit/opening-times
