Basketball was invented in December 1891 by James W. Naismith (1861-1939) of Canada, who was then an instructor at the International YMCA Training School in Springfield, Massachusetts, now Springfield College. The game was invented when Naismith was charged with developing an indoor game to keep his students in shape during the cold New England winter. Originally, basketball was played with peach baskets, and an attendant on a ladder retrieved the ball after a made basket.
