In 1955, at the age of 28, she achieved the status of Chartered Electrical Engineer. She spent much of her life at the Science Museum in London, starting in 1955 and rising to Director at the end of her career from 1973-86, succeeding Sir David Follett. She oversaw a significant expansion of what is now known as the Science Museum Group.
On her first day as Director, Weston was in York, announcing the city as the home of the National Railway Museum (NRM opened in 1975) She oversaw the acquisition of Concorde 002 for the Science Museum, which is now housed at the Fleet Air Arm Museum Yeovilton. She described how the Museum acquired Concorde, saying, "I had a telephone call – it was all telephone calls in those earlier days, not e-mails – and the man didn’t give his name or his department. But he just said, do you want Concorde 002? It's coming to the end of its test service. And I said, well I want to preserve it but I have no place to put it. But yes I'll take it."
Concorde 002 was the second prototype of this Anglo-French aircraft. It was assembled in Britain and made its maiden flight from the British Aircraft Corporation's plant at Filton, Bristol on 9 April 1969. Its last flight was made to the Fleet Air Arm Museum Yeovilton in July 1976.
Dame Margaret was instrumental in establishing the National Museum of Photography, Film and Television (now the National Media Museum) in Bradford, which opened in 16 June 1983. In 1984 she was invited to deliver the MacMillan Memorial Lecture to the Institution of Engineers and Shipbuilders in Scotland. She chose the subject "The Science Museum and Change - Over the last Thirty Years".
Dame Margaret is the Patron of the Heritage Railways Association and the Stroudwater Textile Trust.
