This is a documentary about unsung heroes of World War II. In 1943, a 24-year-old maths student and a GPO engineer combined to hack into Hitler's personal super-code machine - not Enigma but an even tougher system, which he called his 'secrets writer'. Their break turned the Battle of Kursk, powered the D-day landings and orchestrated the end of the conflict in Europe. But it was also to be used during the Cold War - which meant both men's achievements were hushed up and never officially recognized.
Gordon Welchman was one of the original elite codebreakers crucial to the allies defeating the Nazis in World War II. He is the forgotten genius of Bletchley Park. Filmed extensively at Bletchley Park, the centre for codebreaking operations during World War II, this documentary features the abandoned buildings where thousands of people worked tirelessly to crack the codes. Post-war, Welchman moved to the US to be at the centre of the computer revolution. Recently released top secret documents reveal that the case of Gordon Welchman reached the desk of the British prime minister, Margaret Thatcher, and then led to questions being asked in the House of Commons after Welchman's untimely death. Welchman's legacy continues to this day. Welchman's pioneering work in the field of traffic analysis led directly to the modern secret surveillance state, and particularly the use of metadata - as revealed by whistleblower Edward Snowden.
This film tells the incredible story of Bletchley Park and the Ultra Secret. Filmed at Bletchley in collaboration with the Bletchley Trust and with interviews with Bletchley Veterans the BHTV team explain the importance of Bletchley to the Allied War effort. As Sir Harold Hinsley a Bletchley Veteran and Official Historian of British Intelligence during WW2 said, Ultra shortened the war by two to four year's and that the outcome would have been uncertain without it. The film also shows how the allies used the intelligence on land, sea and air. This film shows that the success at Bletchley was not just the result of a few brilliant men and women but the result of the efforts of thousands of unsung heroes.
The Bletchley Circle follows the journey of four ordinary women with extraordinary skills that helped to end World War II. Set in 1952, Susan, Millie, Lucy and Jean have returned to their normal lives, modestly setting aside the part they played in producing crucial intelligence, which helped the Allies to victory and shortened the war. When Susan discovers a hidden code behind an unsolved murder she is met by skepticism from the police. She quickly realises she can only begin to crack the murders and bring the culprit to justice with her former friends. The Bletchley Circle paints a vivid portrait of post-war Britain in this fictional tale of unsung heroes.
During the thrilling social change of the mid-1950s, four remarkable women who previously served secretly during WWII as code-breakers, turn their skills to solving murders overlooked by police. In the process they are plunged into fascinating corners of the city, forge powerful relationships, and rediscover their own powers and potential.
