189 1 12 In Springfield, Massachusetts, USA, Dr. james naismith, a physical education teacher at the YMCA International Training School, invented basketball in order to solve the problem that rugby and baseball could not be played normally in the cold outside in winter. He borrowed the rules of basketball and tennis, and the rules of basketball were only 13. He didn't expect that the basketball game created by him has developed into the third ball game in the United States and the tenth largest in the world, and the number of participants even slightly exceeds that of ice hockey. To commemorate Dr. naismith's contribution to the invention of basketball, the james naismith Memorial Hall of the American Basketball Hall of Fame was built on the campus of Springfield College.
