About the speaker

Jerry McCarthy

Jerry McCarthy’s day job used to be to write software, in areas such as retail systems, cryptography and internationalisation, for a global computing company.

Since his retirement, he now volunteers at The National Museum of Computing (TNMOC), which is situated within the Bletchley Park Campus. There, he talks to visitors about, inter alia, Tunny, Colossus, and the Museum’s slide rule collection. He also volunteers at the Instytut Józefa Piłsudskiego, Hammersmith, where he gives the occasional talk on matters cryptological, such as Enigma and early Polish systems for breaking it.

Jerry is not rich enough to be a full-time cryptocollector, but is interested in crypto simulation techniques which allow virtual acquisition of crypto hardware without needing to find the space to store it. Jerry’s house is definitely not big enough for a Colossus!

Our events are for adults aged 16 years and over.

For overseas delegates who wish to attend the event, please note that BCS does not issue invitation letters.
