Mike Denihan, always known as just "Mike," has died after a colorful career of 35 years as guardian of Harvard athletics. The traditions have grown around his familiar figure at Soldiers Field since the days of the late Percy Haughton. His official duties were to keep unauthorized persons from witnessing the secret practices of the varsity football team. Mike had a failed banner given to him in 1908 by Percy Haughton. Waving this flag before him he lead the snake dances and football rallies in the old days. At other times he would don a tail silk hat, and with the same banner attend the important weddings where Harvard athletes were concerned.
