Breakaway rim While several men claim to have created the breakaway rim, Arthur Ehrat is recognized as the inventor by the Smithsonian Institution's Lemelson Center for the Study of Invention & Innovation.[1][2] A resident of Lowder, Illinois, Ehrat worked at a grain elevator for most of his life and barely knew anything about basketball. In 1975, his nephew, an assistant basketball coach at Saint Louis University, asked him to help design a rim that could support slam dunks. Using a spring from a John Deere cultivator, Ehrat designed a rim that could bend and spring back after 125 pounds of force were applied to it. He called his device "The Rebounder". In 1982, he was awarded a patent for his invention, which was officially called a "deformation-preventing swingable mount for basketball goals".[3]
History of basketball The game of basketball as it is known today was created by Dr. James Naismith in December 1891 in Springfield, Massachusetts, to condition young athletes during cold months. It consisted of peach baskets and a soccer style ball. He published 13 rules for the new game. He divided his class of eighteen into two teams of nine players each and set about to teach them the basics of his new game. The objective of the game was to throw the basketball into the fruit baskets nailed to the lower railing of the gym balcony. Every time a point was scored, the game was halted so the janitor could bring out a ladder and retrieve the ball. After a while, the bottoms of the fruit baskets were removed. The first public basketball game was played in Springfield, Massachusetts, on March 11, 1892.[1]
