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: He published an autobiography, Fatso, in 1987. He was noted as a jovial and humorous person during his playing career and capitalized on that with television and speaking appearances after retiring as a player. He owned and managed a country club near Baltimore. Donovan also appeared ten times on the Late Show with David Letterman, telling humorous stories about his old playing days and about other "old school" footballers he played with and against. He relayed a story that he played without a helmet and in fact is shown on football cards without a helmet. Letterman wore Donovan's No. 70 Colts jersey in the famous Super Bowl XLI commercial with Oprah Winfrey and Jay Leno.  Donovan guest-starred in the Nickelodeon show The Adventures of Pete & Pete in the episode "Space, Geeks, and Johnny Unitas". He also appeared as a guest commentator at the WWF King of the Ring tournament in 1994. Donovan's appearance at the 1994 King of the Ring event would become infamous among wrestling fans for being seemingly uninformed about the product as well as generally befuddled behavior such as repeatedly asking how much certain wrestlers weighed. He was joined by Gorilla Monsoon on play-by-play, who inadvertently referred to Donovan several times as "Art O'Donnell", and Randy Savage.  He was co-host of the popular 1990s program Braase, Donovan, Davis and Fans on WJZ-TV in Baltimore with Colt teammate Ordell Braase. The trio talked more about Art Donovan's fabled stories than contemporary NFL football, but the show held high ratings in its time slot. He was also a pitchman for the Maryland State Lottery and ESPN.
