Patrick Robert Reid, (13 November 1910 – 22 May 1990) was a British Army officer and author of history. As a British prisoner of war during the Second World War, he was held captive at Colditz Castle when it was designated Oflag IV-C. Reid was one of the few to escape from Colditz, crossing the border into neutral Switzerland in late 1942. After the war Reid was a diplomat and administrator before eventually returning to his prewar career in civil engineering. He also wrote about his experiences in two best-selling books, which became the basis of a film, TV series and board game. Source: Wikipedia (en)
