Try getting a hold of a copy of "Legends of Terror" by Richard Munch. It describes the life and acheivements of Harry G. Traver. It's published by Amusement Park Books. Another good book is "Roller Coasters,Flumes and Flying Saucers" by Robert R. Reynolds. It's the story of Ed Morgan and Karl Bacon, the founders of Arrow Development.
