Overview
Frederick Robert Williamson (born March 5, 1938), also known as "the Hammer", is an American actor and former professional football defensive back who played mainly in the American Football League (AFL) during the 1960s. Williamson has had a busy film career, starring as Tommy Gibbs in the 1973 crime drama film Black Caesar and its sequel Hell Up in Harlem. Williamson also had roles in other 1970s blaxploitation films such as Hammer (1972), That Man Bolt (1973) and Three the Hard Way (1974).
Early life and education
Born in Gary, Indiana, Williamson was the only child born to Frank, a welder and Lydia Williamson. Williamson attended DuSable High School in Chicago, where he ran track and played football. He graduated in 1956. After high school, Williamson left Chicago for the United Stated Marines before heading to Evanston, Illinois to attend Northwestern University on a track and field scholarship.
Career
Football
After playing college football for Northwestern in the late 1950s, Williamson was signed as an undrafted free agent by the San Francisco 49ers. When during training camp he was switched to their defense, his attitude over the switch prompted him to play his position with too much aggression, and the coach of the 49ers asked him to quit "hammering" his players. Thus, "The Hammer" quickly stuck and became his nickname.
