It was also the final loss in the coaching career of Clyde Williams, a former Iowa football star.

He was also a brilliant offensive coach who guided Iowa to some of the most lopsided wins in school history.

Hawley, a Dartmouth College graduate, returned to Hanover and continued his business after leaving Iowa in 1915.

In 1923, Dartmouth's football team needed a head coach, and Hawley took the job and stayed for six years.

Successful in private enterprise, he volunteered his services and coached his alma mater for free.
