Willy Ley

Born 2 Oct 1906; died 24 Jun 1969 at age 62.German-American engineer who was a founder of the German Rocket Society. The society was the first group of men (with the sole exception of Robert Goddard) to experiment with rockets. Ley introduced Wernher von Braun to the society. Ley was consultant for the science fiction film Frau im Mond in which the countdown from ten to zero was introduced. Fiercely anti-Nazi, unlike Von Braun, in 1934, he emigrated to the U.S. rather than pursuing military applications of rocketry. In the U.S., he became a popularizer of space exploration and travel, writing many popular books.
