Alvin Lawrence "Moose" Wistert (June 26, 1916 – October 3, 2005) was an American football player. A native of Chicago, Illinois, he played college football at the tackle position for Boston University in 1946 and at the University of Michigan from 1947 to 1949. He began his collegiate football career at age 30 following 12 years of working in a factory and serving in the United States Marine Corps during World War II. He played at the defensive tackle position for the undefeated 1947 and 1948 Michigan Wolverines football teams, both of which finished the season ranked No. 1 in the final Associated Press poll. He also holds the distinction of being the oldest college football player ever selected as a College Football All-American, having been selected to the 1948 College Football All-America Team at age 32 and the 1949 Team at age 33.
He was the last of the three Wistert brothers (along with older brother Francis "Whitey" Wistert and younger brother Albert "Ox" Wistert) to play for the Michigan Wolverines football team. All three Wistert brothers played at the tackle position, were selected as consensus All-Americans, and were later inducted into the College Football Hall of Fame. Alvin was the last of the three brothers to be inducted into the College Football Hall of Fame, receiving the honor in 1973. The Wistert brothers all wore jersey No. 11 at Michigan and are among the seven players who have had their numbers retired by the Michigan Wolverines football program. Their number will be put back into circulation starting on November 10, 2012 before a Michigan home game against Northwestern as part of the Michigan Football Legend program.
