Dr. Helmut Hoelzer with Saturn booster and 7090 model
Against the flame and roar of Saturn's huge 30 million horsepower super-booster is the scientist who directed computation of the test-firing results, Dr. Helmut Hoelzer, with a model of the IBM 7090 computer that enabled his space-team associates to explore new areas of rocket engine research. At the time of this June 1960 photograph, Hoelzer was director of the Computation Division at NASA's Marshall Space Flight Center, Huntsville, Ala., where this test of Saturn's eight-engine super-booster took place that month. The IBM 7090 was to apply the most powerful computing ability in the U.S. space program of the time to analysis of rocket vibration, heat transfer and dozens of other elements.
