The Feast of Sir Marvel “Jack” Parsons

Jack Parsons

Sunday, June 17, is the Feast of Sir Marvel “Jack” Parsons, American rocket engineer and rocket propulsion researcher, chemist, and Thelemic occultist. Born Marvel Whiteside Parsons October 2, 1914 e.v., he was Master of Agape Lodge, O.T.O., in Oakland, California, from 1942 until his death in 1952.

Wikipedia says: “Parsons’ occult and libertarian writings were published posthumously, with Western esoteric and countercultural circles citing him as one of the most significant figures in propagating Thelema across North America. Although academic interest in his scientific career was negligible, historians came to recognize Parsons’ contributions to rocket engineering. For these innovations, his advocacy of space exploration and human spaceflight, and his role in the founding of JPL and Aerojet, Parsons is regarded as among the most important figures in the history of the U.S. space program. He has been the subject of several biographies and fictionalized portrayals, including the television drama Strange Angel.”

In honor of Jack Parsons and his contributions to scientific innovations, why not enjoy this delicious frozen cocktail?
