Brooke played seven years of college football at Swarthmore College and then at the University of Pennsylvania. He was selected as an All-American in 1894 and 1895 while playing for the University of Pennsylvania. Penn was undefeated and won the national championship of football in the two seasons that Brooke was named an All-American. All-American selector, Caspar Whitney called Brooke a "very hard man to stop. He strikes the line with almost irresistible force."
