It was 1930 and 16-year-old George Nissen, a member of his high school gymnastics and diving teams, was goofing off in his parents’ garage when he decided to stretch canvas over a rectangular steel frame, using materials he found in a local junkyard, according to MIT . Seven years later when he was in business school at the University of Iowa, he and his gymnastics coach refined the invention with nylon and started a traveling acrobatics troupe called the Three Leonardos.
They initially called it a “bouncing rig,” but after traveling through the Midwest and Southwest, they learned the Spanish word for diving board, “el trampolin” and changed the name to Trampoline and got a patent.
