Oliver Marsten Sansen (March 6, 1908 – March 21, 1987) was an American football player.
Sansen was born in Alta, Iowa, in 1908. He played college football for the Iowa Hawkeyes from 1929 to 1931.[1] He was selected as the most valuable player on the 1930 Iowa Hawkeyes football team. He also competed in the shot put and hammer throw for the Iowa track team.[2]
He then played professional football in the National Football League (NFL) as a fullback for the Brooklyn Dodgers. He appeared in 41 NFL games, 22 as a starter, from 1932 to 1935.[3]
In January 1936, Sansen accepted a job as a salesman for Bankers Trust Co. in New York City, deciding then to end his football career.[4] He later lived in San Lorenzo, California, and sold automobiles in Alameda, California. In 1961, he was honored as one of the nation's top 100 salesmen by the American Motors Corporation.[5] He died in 1987.[6]
