Final Secrets of the Zimmermann Telegram

Former Hoover archivist Dale Mayer will present a story of his findings in the archives- a telegram which changed the course of WWI. The story begins in 1915 when British Naval Intelligence agents managed to steal German military code manuals that enabled British Naval Intel to anticipate and frustrate German plans. Its impact on the outcome of the war, and the incredible final secrets of the Zimmermann telegram, have never been fully revealed- until now.

In the telegram, were instructions to Germany’s foreign minister to Mexico detailing a plan for Mexico to invade the southern United States while Germany battled on east coast. Mexico would be given sufficient arms and training from Germany and whatever land they could reclaim. Mayer’s research outlines the rest of the story.

The event begins with a short reception at 5:30 p.m. on Thursday, Oct. 24 in the Hoover Presidential Library and Museum lobby, followed by the talk at 6 p.m. The event, hosted by the Hoover Presidential Foundation, is free and open to the public.
Retired after 30 years' experience, Mayer was a Hoover Presidential Library principal archivist for collection management, document preservation and reference services. In retirement he taught college level courses for the Institute on Learning in Retirement on topics such as The Era of the American Revolution, Combat Experiences of Civil War Soldiers, Lost Archival Treasures from All Over, and The Importance and Impact of History.

Mayer has produced many books, journal articles and workshops. He believes Final Secrets of the Zimmermann Telegram will undoubtedly have an impact on the manner in which historians re-examine issues from both World Wars and the Cold War.
