An American college and professional football defensive end. A graduate of Chaminade High School in Mineola, New York, the Boston College standout was one of several Boston-area athletes to join the American Football League's Boston Patriots. He was nicknamed "Wildman" by his Patriot teammates because of his unpredictable antics, such as running out onto Kansas City's snow-covered Municipal Stadium field clad in only his helmet and athletic supporter, hitting his head on metal locker doors or ramming his forearms through locker room walls to motivate himself. Eisenhauer was an AFL All-Star in 1962, 1963, 1964 and 1966, and is a member of the Patriots All-1960s (AFL) Team.
