After studying physics in Leipzig, Heidelberg and Berlin and obtaining his doctorate, Haber served in World War II for the German Luftwaffe as a reconnaissance aviator until 1942. He returned to the Kaiser-Wilhelm-Institut für Physik, where he headed a small Potsdam-based division constructing a diffraction spectrograph. After the end of the war, Haber — as well as several other Germans involved in military research like Wernher von Braun — was targeted by the Operation Paperclip with the aim of denying scientific expertise and knowledge to the Soviet Union and bringing researchers and scientists to the United States; Ultimately this operation resulted in a considerable contribution to the development of NASA. Haber at first stayed in the American occupied zone of Germany and lectured at Heidelberg. However, in 1946, he emigrated to the United States and joined the USAF School of Aviation Medicine at Randolph Air Force Base. Together with fellow GermanHubertus Strughold, he and his brother Dr. Fritz Haber made pioneering research into space medicine in the late 1940s. The brothers proposed parabolic flights for simulating weightlessness. In 1952, he became associate physicist at UCLA; in the 1950s, Haber eventually became the chief scientific consultant to Walt Disney productions. He later co-hosted Disney’s Man in Space with von Braun. When the Eisenhower administration asked Disney to produce a show championing the civilian use of nuclear power, Heinz Haber was given the assignment. He hosted the Disney broadcast called Our Friend the Atom and wrote a popular children’s book with the same title, both of which explained nuclear fission and fusion in simple terms. General Dynamics, a manufacturer of nuclear reactors, sponsored Our Friend the Atom and the nuclear submarine ride at Disneyland’s Tomorrowland. In the 1960s and 1970s, he was known in Germany as a popular science spokesperson and wrote magazine columns and numerous books and presented his own TV programs like Professor Haber experimentiert, Das Mathematische Kabinett, Unser blauer Planet, Stirbt unser blauer Planet?, Professor Haber berichtet, and WAS IST WAS mit Professor Haber. He was founding editor of the German science magazine Bild der Wissenschaft from 1964 to 1990. His memorable experiments included one where the onset of a nuclear chain reaction was simulated with hundreds of mousetraps, each one having been loaded with two ping pong balls. Heinz Haber had two children, Kai and Cathleen, from his first marriage, and a third child, Marc, from the second. His first wife Anneliese lives in Tucson, Arizona, his second wife Irmgard in Hamburg, Germany.
