Basketball is the only major American sport with a clearly identifiable inventor. James Naismith wrote the sport’s original 13 rules as part of a December 1891 class assignment at a Young Men’s Christian Association (YMCA) training school in Springfield, Massachusetts. Born and educated in Canada, Naismith came south to pursue his interests of physical education and Christian ministry. Naismith expanded on an assignment to create a game that could be played in YMCA gyms during the winter.
