William Carey Foster (April 1, 1936 – May 27, 2015) was an American college basketball coach who won over 500 games during a career that spanned 30 years. Foster, a native of Palatka, Florida, compiled an overall record of 532–325 in 30 seasons. He succeeded Tates Locke at Clemson University on April 9, 1975.[1] Foster died of Parkinson's disease in Charlotte, North Carolina on May 27, 2015.[2]
He was one of two men's basketball head coaches named Bill Foster in the Atlantic Coast Conference from 1975 to 1980. The other was at Duke University. Neither were related to each other. Nicknames were used to differentiate the two, with the Tigers coach referred to as Clem Foster and the other as Duke Foster.[3]
