Hollywood star Hedy Lamarr has long had a place of honour in Bletchley Park, at the National Museum of Computing. It’s a fascinating place, just a short walk away from Hut 8, where Alan Turing and his colleagues were codebreaking in the early 1940s. Lamarr’s work is presented next to luminaries such as Ada Lovelace, the 18th century mathematician and author of the first computer algorithm.
