The Forefathers of Rocketry

John Parsons began experimenting with using glue as a binding agent to keep the loose powder in his engines together at age 18. He married his high school sweetheart, Helen Northrup, and became increasingly influential in the developing science of rocketry. In 1939, Jack's interest in fantasy, kindled by those amazing stories comics he devoured as a child, led him to pick up a book by Alistair Crowley.
