Clark Shaughnessy
Clark Daniel Shaughnessy was an American football coach and innovator. He is sometimes called the father of the T formation and the original founder of the forward pass, although that system had previously been used as early as the 1880s. Shaughnessy did, however, modernize the obsolescent T formation to make it once again relevant in the sport, particularly for the quarterback and the receiver positions. He employed his innovations most famously on offense, but on the defensive side of the ball as well, and he earned a reputation as a ceaseless experimenter.
Shaughnessy was born on March 6, 1892 in St. Cloud, Minnesota, the second son of Lucy Ann and Edward Shaughnessy. He attended North St. Paul High School, and prior to college, had no athletic experience. When he attended the University of Minnesota, however, he played college football under head coach Henry L. Williams and alongside halfback Bernie Bierman. Shaughnessy considered Williams to be footballs greatest teacher, and Williams considered him to be the best passer from the Midwest. Shaughnessy handled both the passing and kicking duties for the team.
