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.
