Invention of basketball
In 1891, while working as a physical education teacher at the YMCA International Training School in Springfield, Massachusetts, Naismith was asked to make a game that would not take up much room, was not too rough, and at the same time, could be played indoors. He had no idea he would invent what would become the most popular indoor sport in the United States.

Inspired by a Canadian game he played as a child in Canada called "Duck on a Rock," Naismith's game started December 15, 1891 with thirteen rules (modified versions of twelve of those are still used today), a peach basket nailed to either end of the school's gymnasium, and two teams of nine players. On January 15, 1892 Naismith published the rules for basketball. The original rules did not include what is known today as the dribble. They initially only allowed the ball to be moved up the court via a pass. Following each "goal" a jump ball was taken in the middle of the court. Although it was not a rule, players would commonly use the dust of coal to cover the palms of their hands, allowing them to get a better grip on the ball. The coal palm was used up until the early 1930s. Also interesting was the rule concerning balls out of bounds - the first player to retrieve the ball received possession.

Basketball became a popular men's sport in the United States and Canada very quickly, and spread to other countries as well. Additionally, there were several efforts to establish (under modified rules) a women's version. Naismith himself was impressed with how quickly women caught onto the game and remarked that they were quick to understand the nature of the teamwork involved. He observed some women playing at a college in Springfield, MA, and was instrumental in promoting the sport for women in New England. This met with great resistance in some circles and was consequently far slower to become truly widespread.

Naismith felt that it was appropriate to modify the rules somewhat to account for his perception of women. The men's sport was officially added to the Olympic Games program at the 1936 Summer Olympics in Berlin. There, Naismith handed out the medals to three North American teams; United States, for the Gold Medal, Canada, for the Silver Medal, and Mexico, for their Bronze medal win. Women's basketball finally became an Olympic event in Montreal during the 1976 Summer Olympics. Previously, there had been a men's basketball competition, in connection with the 1904 Games at St. Louis, USA.

Coaching career
Naismith moved to the University of Kansas, in 1898, following his studies in Denver, becoming a professor and the school's first basketball coach. The University of Kansas went on to develop one of the nation's most storied college basketball programs.

Naismith is the only Kansas coach to have a losing record (55-60) during his tenure at the school. Nevertheless, Naismith has one of the greatest coaching legacies in basketball history. Naismith coached Forrest "Phog" Allen, his eventual successor at Kansas, who went on to become one of the winningest coaches in U.S. college basketball history. The actual playing surface of Allen Fieldhouse in Lawrence, Kansas is named the James Naismith Court. Phog Allen was the college basketball coach of Dean Smith and Adolph Rupp, who are two of the winningest men's college basketball coaches, and won a combined total of six NCAA championships.

Adolph Rupp was the college basketball coach of Pat Riley who is one of the winningest coaches in NBA history and has won six NBA championships. Dean Smith went on to be the college basketball coach of hall of fame coach Larry Brown (who also coached at the University of Kansas), current North Carolina coach Roy Williams (who also coached for 15 seasons at the University of Kansas previous to that), and basketball great Michael Jordan. In the late 1930s Naismith played a role in the formation of the National Association of Intercollegiate Basketball, which later became the National Association of Intercollegiate Athletics.

In August 1936, while attending the Berlin Olympics, he was named honorary President of the International Basketball Federation.

Athletic career
Naismith was a star gymnast, lacrosse player and football player at McGill University, where he graduated among the top 10 in his class with a B.A. Honours in 1887. In 1885-86 he won the Wicksteed Silver Medal as the gymnastics champion of the school's junior class. In his graduating year, he won the prestigious Wicksteed Gold Medal as the top athlete of the university's senior class.

Personal life
Naismith married Maude Sherman in 1894 and they had five children. Naismith was also a Presbyterian Minister and became a naturalized American citizen on May 4, 1925. In 1939 he was awarded his Doctor of Divinity from The Presbyterian College, Montreal. After Maude's death in 1937, he married Florence Kincade on June 11 1939, less than six months before his own death, in Lawrence, Kansas, of a cerebral hemorrhage.

He has been honored extensively in his native country Canada and also in other nations. He was the founding inductee when on February 17, 1968 the Naismith Memorial Basketball Hall of Fame, named in his honor, opened in Springfield, Massachusetts. He was also an inaugural inductee to the McGill University Sports Hall of Fame in 1996.

In 2005 James Naismith's grandson, Ian Naismith, planned on selling the original copy of the thirteen rules. The rules were passed down on Naismith's death to his youngest son, James Naismith, who was Ian's father. James lived in Corpus Christi, Texas.

Naismith was a Freemason and a member of Sigma Phi Epsilon fraternity.
