(CNN)Here's a look at college football's Heisman Trophy.
The Heisman Memorial Trophy is awarded each year to the "most outstanding football player in the United States."
December 14, 2019 - Louisiana State University quarterback Joe Burrow wins the Heisman Memorial Trophy.
December 8, 2018 - University of Oklahoma quarterback Kyler Murray is named the 2018 Heisman Trophy winner. This marks the first time since the 1945-1946 season that one school has had back-to-back winners. Oklahoma quarterback Baker Mayfield won in 2017.
About the Trophy
The Heisman Memorial Trophy is named in honor of long-time college football coach John W. Heisman, who was also the athletic director of the New York Downtown Athletic Club.
The trophy is 13.5 inches tall, weighs 45 lbs, and is cast in bronze.
The model for the trophy was Ed Smith, a player for New York University in 1934.
School with the most wins: Notre Dame and the University of Oklahoma are tied with seven winners, and Ohio State with seven wins. (One player won twice - see below)
Voting and Award Process
The Heisman Trophy Trust oversees balloting.
There are 927 ballots: "Sectional representatives" choose 145 voters, usually sports journalists, in six regions across the country, for 870 ballots. Each former Heisman winner can vote (56) and there is one fan vote through a special program.
Every year, several Heisman finalists travel to the award ceremony in New York where the winner's name is revealed.
