G. Harry Stine, co-founder of the hobby of model rocketry. (with Orville Carlisle, a hobby pyrotechnician/shoe store salesman who invented the black powder pre-fab model rocket engine) G. Harry was also instrumental in forming the NAR and was it's first president, and working with/thru NFPA to get model rocketry differentiated legally from fireworks, a large undertaking to make model rocketry 'legal' in more areas of the country. G. Harry Stine started the first commercial model rocket company, Model Missiles Inc., and sold kits and "handmade" Carlisle engines until a young man named Vern Estes invented a machine named "mabel" to produce model rocket engines with great speed and efficiency. Shortly thereafter, Vern struck out with his own company and the rest is history. G. Harry also wrote what is generally considered to be the "bible" of model rocketry, the venerable "HANDBOOK OF MODEL ROCKETRY" which is in it's seventh or eighth revision currently, IIRC, currently revised by his son, Bill Stine, who owns/runs Quest, the other big model rocket company behind Estes.

Hope this helps OL JR
