Henry Clifford "Doc" Carlson (July 4, 1894 – November 1, 1964) was an American basketball coach and football player. He is a Naismith Basketball Hall of Fame inductee as the men's college basketball coach of his alma mater, the University of Pittsburgh, from 1922 to 1953. At Pitt he compiled a record of 367–247 record (.595). His 1927–28 team finished the season with a 21–0 record and was retroactively named the national champion by the Helms Athletic Foundation and the Premo-Porretta Power Poll; Carlson's Panthers would receive retroactive recognition as the Helms national champion for the 1929–30 season as well. Carlson also led Pitt to the Final Four in 1941. As a student at the university, Carlson was also a First Team All-American end on Pitt's football team under coach "Pop" Warner. Carlson also lettered in basketball and baseball. Biography Carlson was born in Murray City, Ohio. He played high school football, basketball, and baseball (1910–1914) at Bellefonte Academy in Bellefonte, Pennsylvania. During his undergraduate years at the University of Pittsburgh (1914–1918) he earned three letters in basketball, two in baseball, four in football. He played on the 1916 Pitt football team that is widely regarded as that season's national champion and was selected as an All-American football player while playing for Pitt's undefeated 1917 team. After graduation in 1918, Carlson completed his medical degree at Pitt in 1920, but then joined the Cleveland Indians professional football team for one season. When in 1922 Andrew Kerr, who was Pitt's basketball coach and assistant football coach, left to become football head coach at Stanford University, Pitt hired "Doc" Carlson as its new basketball coach. Simultaneously he practiced as a physician for the Carnegie Steel Company. Carlson was famous for his Figure 8 offense, an innovation that many coaches copied. In 1928 Pittsburgh went a perfect 21–0 and the national championship. His Panthers won another national title in 1930. (Both were selected as national champions, prior to the advent of NCAA Tournament, by the Helms Athletic Foundation.) He also led the Panthers to Eastern Intercollegiate Conference championships in four out of the seven years of the conference's existence. In 1931 Carlson became the first Eastern coach to take a collegiate team westward, going on the road to beat the University of Kansas, the University of Colorado, Stanford, and the University of Southern California. He also wrote the book You and Basketball. Legend
