Franklin Pierce Mount Pleasant Jr., called Frank, was born into the nation on the Tuscarora Indian Reservation in New York; it is the Sixth Nation of the Iroquois Confederacy. He was the son of Chief John and Rachael. At a time when federal Indian policy emphasized assimilation, Mount Pleasant was sent as a child to be educated at Indian boarding schools. He eventually attended the Carlisle Indian Industrial School in Pennsylvania from 1905 to 1909, where he competed as both a long jumperon the track team and as a quarterback and halfback on the football team. The 1907 Carlisle Indian team, coached by Glenn Scobey Warner went 10–1 with a 26–6 victory over the perennial powerhouse, Harvard. The team's only loss of the season came against Princeton, in a game in which Mount Pleasant did not play. His teammates included Jim Thorpe, future Pro Football Hall of Famer, and Albert Exendine, future College Football Hall of Fame inductee. Despite being a second-team All-American, Mount Pleasant never played professional football; the National Football League was not started until 1920. He did play semi-pro football in Buffalo. It is said that Mount Pleasant invented the spiral pass. During college, Mount Pleasant tried out for the Olympics and became the first Carlisle student to qualify; he made both the 1904 and 1908 U.S. Olympic track teams. At the 1908 Olympics in London, Mount Pleasant finished sixth in both the triple jump and the long jump competitions. This ended his track and field career, leaving him with career bests of for the long jump and for the triple jump.
Coaching career
After the Olympics, Mount Pleasant completed his studies at Dickinson College, becoming its first Native American graduate. He worked as the head football coach at Franklin & Marshall College for the 1910 season. His coaching record at Franklin & Marshall was 4–3–2. For the following three years he was the head football coach at the Indiana Normal School, now Indiana University of Pennsylvania. His last two teams won state championships. Mount Pleasant moved to the University of Buffalo in 1915, where he coached the football team to a 3–4 season. Mount Pleasant's coaching career was cut short by World War I. He was commissioned and served as an officer, a first lieutenant.
After the war, Mount Pleasant settled in Buffalo, New York, not far from the Tuscarora reservation. He played several years of semi-pro football with the Buffalo All-Stars. The team included many former college stars, including Tall Chief, a teammate at Carlisle Indian School. Mount Pleasant worked odd jobs throughout the remainder of his life. He enjoyed playing the piano. His death in 1937 is a mystery, as two policemen found him unconscious on a Buffalo sidewalk. He died three days later at Emergency Hospital. Initial reports indicated that Mount Pleasant sustained a fractured skull, "possibly by violence." But the next day, Francis M. Kujawa, the Buffalo medical examiner, ruled the death the result of an accidental fall.
