William H. Koll (August 12, 1923 – September 27, 2003) was an American wrestler and coach.
Born in Fort Dodge, Iowa in 1923, Koll was a wrestler at Iowa State Teachers College (now the University of Northern Iowa) and later became a wrestling coach, most notably at his alma mater and for the Penn State Nittany Lions wrestling team. As a wrestler, Koll was undefeated (72–0) and won three straight NCAA Championships (1946–1948). He was twice voted most outstanding wrestler at the national tournament, the first wrestler to achieve this honor.
Koll's college career was interrupted by World War II, during which he participated in the Normandy landings and earned a Bronze Star. Koll competed for the U.S. at the 1948 Summer Olympics in London[1] and placed fifth in the freestyle competition. As a professor of Health and Physical Education and coach, Koll led Penn State for 14 seasons (1965–1979), which included unbeaten dual meet campaigns in 1967, 1970, 1971, 1972 and 1974.
Koll is a member of the National Wrestling Hall of Fame[2] and the father of Rob Koll, a collegiate wrestling head coach and NCAA champion at the University of North Carolina at Chapel Hill.[3] Koll died in 2003 in State College, Pennsylvania at the age of 80.
