George Harry Stine attended the University of Colorado in Boulder. Upon his graduation he went to work at White Sands Proving Grounds, first as a civilian scientist and then, from 1955–1957, at the U.S. Naval Ordnance Missile Test Facility as head of the Range Operations Division.
Stine and his wife Barbara were friends of author Robert A. Heinlein, who sponsored their wedding, as Harry's parents were dead and Barbara's mother too ill to travel. Several of Heinlein's books are dedicated one or both of them, most particularly Have Space Suit - Will Travel. Stine also wrote science articles for Popular Mechanix.
I am using this book to develop content for my new university course titled "Humans in Space." The level of detail is appropriate for an undergraduate level course on the effects of the space environment on the human system.
