Leo Nomellini established himself as one of the NFL's first great two-way linemen, dominating at both offensive and defensive tackle while setting durability records that defined ironman toughness across fourteen seasons. Born on June 19, 1924, in Lucca, Italy, Nomellini immigrated to America as an infant, settling in Chicago, where he dropped out of Crane High School to work in a foundry supporting his family. He enlisted in the Marine Corps in 1942, first playing football with the Cherry Point team before seeing combat at Saipan and Okinawa. After his military service, he earned a scholarship to the University of Minnesota, where, despite never seeing a football game before playing in one, he became a two-time All-American (1948, 1949) and finished seventh in the hammer throw at the 1948 NCAA track and field championships.
