Background: Art Donovan, born June 5, 1924, was the son of Arthur Donovan, Sr., a boxing referee, and the grandson of Professor Mike Donovan, the world middleweight boxing champion in the 1870s. Art attended Mount Saint Michael Academy in the Bronx. He received a scholarship to the University of Notre Dame in 1942 but left after one semester to join the United States Marine Corps, enlisting in April 1943. He served four years, to include service in the Pacific Theatre during World War II.
Context: In each of his first three seasons, Donovan played for a team which went out of business. He started out with the first Baltimore Colts, who folded after his rookie season in 1950, followed by the New York Yanks in 1951, and their successor, the Dallas Texans, in 1952. After the Texans franchise was moved to Baltimore in 1953 and became the second Baltimore Colts, Donovan played with that team. He became one of the stars in an outstanding defense and was selected to five straight Pro Bowls, from 1953 through 1957. The Colts won back-to-back championships in 1958 and 1959. He was selected to the Pro Football Hall of Fame in 1968.  During his career, Donovan played in what many believe was one of the most important games in NFL history, the 1958 title game between the Colts and the New York Giants. The contest between the two teams took place on December 28, 1958 and ended in a 17-17 tie. Because it was the championship game, it went into overtime, the first NFL game to do so. Donovan made an important tackle during the overtime, stopping the Giants and allowing Johnny Unitas to lead the Colts on an 80-yard scoring drive to win the game.  "The NFL's first overtime game, witnessed by 40 million viewers on nationwide television, captured the public imagination and became known as the "greatest game ever played." Donovan was one of 12 Hall of Fame players to take part - six of them Colts - but at the time he was not aware of the game's significance"
