The first usable model, made in 1934, was constructed, with help from his Coach and the school’s Engineering Department, out of inner-tube rubber while George was a student attending the University of Iowa. George was a champion gymnast throughout college before graduating with a Business Degree in 1937.
The sport was initially called “rebound tumbling” before George trademarked the name “trampoline” which he got from the Spanish word trampolin meaning “diving board” or “springboard.”
The trampoline slowly became a common household term, no longer being used for training purposes, but for recreational use. In 2000 Trampoline and Tumbling became an official Olympic sport. George was in the crowd that day watching his dreams come true.
