Richard Cresson Harlow (October 19, 1889 – February 19, 1962) was an American football player and coach, as well as an oologist. Harlow served as the head coach at Pennsylvania State University (1915–1917), Colgate University (1922–1925), Western Maryland College (1926–1934), and Harvard University (1935–1942, 1945–1947). He is credited with pioneering modern defensive schemes. Often fielding undersized teams, Harlow coordinated stunts to avoid blockers, rather than trying to overpower them. His offensive style utilized shifts, reverses, and lateral passes. Harlow was inducted into the College Football Hall of Fame as a coach in 1954.
