The correct answer to this question is James Naismith, and he created the sport of basketball. His creation came in 1891 when he was 30 years old. Not only did he create the sport, but he wrote the rules of basketball. James Naismith also was the founder of the basketball program at the University of Kansas.
13 years later, Naismath was able to see his sport become demonstrated at the Olympics and see it become an official event at the Berlin Summer Olympics in 1936. He created basketball after his difficulties with combating a rowdy class and the urge from his boss to create something to keep them in shape.
