William Dennison "Denny" Clark (October 21, 1885 – May 30, 1932) was an American football player. He played for the University of Michigan from 1903 to 1905. He was blamed for Michigan's 1905 loss to the University of Chicago, which ended the Wolverines' 56-game unbeaten streak. He committed suicide at a hotel in Salem, Oregon, in 1932. Early years and lineage A native of Detroit, Michigan, Clark was the son of the Rev. Rufus Wheelwright Clark (1844–1909), who served for many years as the rector at St. Paul's Episcopal Church in Detroit, and Lucy (Dennison) Clark (1854–1928). His maternal grandfather was William Dennison, Jr. (1815–1882), who served as the 24th Governor of Ohio and as U.S. Postmaster General in the Cabinet of President Abraham Lincoln during the American Civil War. University of Michigan Clark played football for Fielding H. Yost's "Point-a-Minute" teams at the University of Michigan from 1903 to 1905. Clark was a versatile player who played at the halfback, fullback, and end positions. He was the fourth-leading scorer on the 1904 Michigan team with 10 touchdowns. 1905 Chicago game In the final game of the 1905 season, Clark was blamed for Michigan's 2–0 loss to the University of Chicago, ending a 56-game unbeaten streak dating back to the first game of the 1901 season. Going into the final game of the season, the Wolverines were unbeaten, untied, and unscored upon. The two teams played to a scoreless tie for more than 50 minutes, when Clark was tackled for a safety as he attempted to return a punt from behind the goal line. The Detroit Free Press described the play as follows: Eckersall, through failure of his team mates to advance it, was called upon to punt. Chicago at the time was on Michigan's 43-yard line. Barlow and Clark were playing back to take the kick, but the ball, low and well driven, went between them. Clark went behind the line after the ball, with two Chicago players down on him. there was hardly a chance to get away, and he could have played it safe and avoided a score by merely touching the ball down behind the line. He shook off the two tacklers, however, and tried to run the ball back. He was a yard or so over the line on the field when Carlin reached him, and threw him back, forcing him over his own goal
