The museum is governed by its board of trustees. There are currently eight trustees, who are also directors of the museum company.

Tony Sale (pictured above), who led the team that rebuilt Colossus, was a co-founding trustee of The National Museum of Computing. He died unexpectedly in August 2011, but his legacy lives on. Without Tony, The National Museum of Computing probably would not exist today.

Professor Martin Campbell-Kelly

Professor Martin Campbell-Kelly joined the Board in 2016. Martin is a computer historian and an emeritus professor in the Department of Computer Science at the University of Warwick. He became fascinated by computing in the mid-1960s and enrolled for a computer science degree at the University of Manchester where he was taught by some of the pioneers of early computing.

Martin has authored several books including histories of ICL, software, and international computing. He is a Fellow of the British Computer Society, a member of the ACM History Committee and a committee member of the BCS Computer Conservation Society. He also sits on a number of editorial boards including the IEEE Annals of the History of Computing.

Over the past few years, Martin has become increasingly involved with the museum through his work on the EDSAC reconstruction project and in acting as a source of knowledge and advice about computing history for the museum.
