Steve Belichick, American football player, coach and scout (d. 2005)
Stephen Nickolas Belichick (January 7, 1919 – November 19, 2005) was an American football player, coach, and scout. He played college football at Western Reserve University, now known as Case Western Reserve University, from 1938 to 1940 and then in the National Football League (NFL) with the Detroit Lions in 1941. After serving in World War II, Belichick began his coaching career. From 1946 to 1949, he was the head football coach and the head basketball coach at Hiram College. He continued on as an assistant coach in college football with stints at Vanderbilt University (1949–1952), the University of North Carolina at Chapel Hill (1953–1955), and then for 34 years at the United States Naval Academy (1956–1989).

Belichick's son, Bill, is the current head coach of the NFL's New England Patriots. His grandsons, Stephen and Brian, serve as position coaches for the Patriots — outside linebackers and safeties, respectively.
