In the fall of 1940, British Prime Minister Winston Churchill ordered a small team of scientists on a clandestine transatlantic mission to deliver his country’s most valuable military secret—a revolutionary radar component —not to the U.S. government, but to a mysterious Wall Street tycoon, Alfred Lee Loomis. Using his connections, his money and his brilliant scientific mind, Loomis and his team of scientists developed radar technology that would arguably play a more decisive role than any other weapon in the war. The Secret of Tuxedo Park tells a long-overlooked story of an individual who helped alter the course of history in World War II.
