The National Museum of Computing

694. Margaret Sale

Margaret Sale, from Milton Keynes, is a driving force behind The National Museum of Computing at Bletchley Park.

Having led efforts to save the site from demolition in 1992, Margaret and her late husband Tony then shaped the development of the National Museum of Computing.

The museum now attracts 30,000 visitors every year and Margaret gives tours with a special focus on how Colossus, the world’s first programmable electronic computer, was rebuilt by her late husband.

She is also the first-ever President of the Museum’s Members’ Club which, under her leadership, has become a thriving community of supporters who take part in regular events. 

In a personal letter to Margaret, Prime Minister Theresa May said: 

“The courageous and ground-breaking work that took place at Bletchley Park was of vital importance to the British war effort. We all owe a huge debt of gratitude to everyone involved for the freedoms we enjoy today. Your important work is ensuring their important contribution is not forgotten and is preserving their legacy for generations to come.”

Margaret said:

“To receive the Point of Light Award is a great honour and a complete surprise. To do so as we celebrate ten years since the official opening of the museum is especially pleasing. With support from private and corporate donors, volunteers, staff and fellow trustees have worked with great skill and dedication to revitalise the home of Colossus to tell the developing story of computing. We see that our exhibits inspire students and the general public – that in turn inspires us. Receiving this recognition from the Prime Minister is a great boost to our ambitions and helps spread the word.”

Andy Clark, Chair of The National Museum of Computing, said:

“Margaret Sale completely encapsulates the definition of an inspirational volunteer. She has given unfailing support and commitment in many roles to The National Museum of Computing since its foundation. In particular, her engaging manner in telling the story of the once-secret Colossus to ensure that we remember the code-breaking heroes behind its creation inspires students to consider the part they can play in improving our cybersecurity.”
