The museum is governed by its board of trustees. There are currently six trustees, who are also directors of the museum company.
Andy specialises in cryptography and hi-tech aspects.
Matt focuses on finance and fund raising.
Jon looks after legal and contractual issues.
Kevin specialises in post-1945 computer history and is also Secretary of the Computer Conservation Society (a specialist group of the British Computer Society).
Tim focuses on strategic planning and finance. Tim is also the founder and Chairman of Bletchley Park Capital Partners Ltd.
Margaret, who has been involved with TNMOC from its founding, provides all-round support and an important historical perspective.
Tony Sale (pictured above), who led the team that rebuilt Colossus, was a co-founding trustee of TNMOC. He died unexpectedly in August 2011, but his legacy lives on. Without Tony, TNMOC probably would not exist today.
