Jack Parsons (1914–1952) was an American rocket engineer and rocket
propulsion researcher, chemist, and Thelemite occultist. Associated with
the California Institute of Technology (Caltech), Parsons was one of the
principal founders of both the Jet Propulsion Laboratory (JPL) and the
Aerojet Engineering Corporation. He invented the first rocket engine
using a castable composite rocket propellant, and helped develop both
liquid-fuel and solid-fuel rockets. Inspired by science fiction
literature, he developed an interest in rocketry in his childhood and in
1928 began amateur rocket experiments with school friend Ed Forman. In
1934 he united with Forman and graduate student Frank Malina to form the
Caltech-affiliated GALCIT Rocket Research Group, supported by Guggenheim
Aeronautical Laboratory chairman Theodore von Kármán. After working on
Jet-Assisted Take Off for the U.S. military, the GALCIT Group became JPL
in 1943. For his contributions to rocket engineering, his advocacy of
space exploration and human spaceflight, and his role in the founding of
JPL and Aerojet, Parsons is regarded as one of the most important early
figures of the U.S. space program.
