Often known as "Hammerin' Hank," professional baseball player Hank Greenberg began his Major League career in the early '30s, playing for the Detroit Tigers. His record grew steadily more impressive over the course of his seasons with the team, and by the time the U.S. entered WWII in 1940, Greenberg had been voted to the All-Star team four times and won the MVP award twice.
After attending the Air Force's Officer Candidate School, Greenberg served as a first lieutenant in World War II, surveying locations for B-2 bases in the China-Burma-India Theater. He returned to baseball after returning home at the end of the war in 1945 and set a record that season with 11 multiple-home run games, a record that wouldn't be broken until 1998. He switched from the Tigers to the Pittsburgh Pirates for the 1947 season, and subsequently retired as a player. He would become general manager and partial owner of the Cleveland Indians and remain with them until the late '50s. Greenberg subsequently worked in investment and finance. He passed away in 1986 at the age of 75.
