Charles W. Bowser was an American football coach. He served as the head football coach at Grove City College from 1924 to 1926, at Bowdoin College from 1930 to 1934, and at the University of Pittsburgh from 1939 to 1942, compiling a career college football record of 40–47–6.

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.
