The Zimmermann Telegram tells the story of how the US became embroiled in World War One. The threat from Germany came home to the United States 100 years ago this month, courtesy of an intercepted telegram sent by the German Foreign Secretary, Arthur Zimmermann. The tricky thing was, British intelligence didn’t want the US finding out they were reading what was coming over those cables. That made it rather difficult to warn the US, without giving the game away and thereby doing enormous diplomatic damage.
We hear from the grandsons of two key figures in this story; Nigel de Grey played his part in decrypting this all-important message in Room 40, and went on to be crucial to codebreaking during World War Two. The other, Thomas Hohler, was our man in Mexico at the time. Last summer their grandsons met up at Bletchley Park, reflecting on the significance of the telegram and their ancestors’ involvement in bringing it to light.
Also in this episode, you really never do know who you might meet at Bletchley Park. Eagle-eyed listeners may have spotted the TV historian, Dan Snow, waxing lyrical on social media recently, about the wonders of the Home of the Codebreakers. He came to visit and - like most people when they first see how brilliantly the story is now told - was moved and amazed. He stopped for a chat with Bletchley Park’s very own broadcast-friendly historian, Dr David Kenyon.
Throughout this year, we’ll bring you more never-heard-before interviews with veterans of Bletchley Park and its outstations, celebrating the ongoing Oral History project, as well as freshly researched stories about what the Codebreakers achieved and the difference it made to the outcome of the war, in the Bletchley Park Podcast’s exclusive It Happened Here series.
