Henry Benjamin "Hank" Greenberg (January 1, 1911, New York, New York – September 4, 1986), nicknamed "Hammerin' Hank," was an American professional baseball player in the 1930s and 1940s.

A first baseman primarily for the Detroit Tigers, Greenberg was one of the premier power hitters of his generation. He hit 58 home runs in 1938, the most in one season by any player between 1927, when Babe Ruth set a record of 60, and 1961 when Roger Maris surpassed it. He was a five-time All-Star, was twice named the American League's Most Valuable Player, and was elected to the Hall of Fame in 1956.

Greenberg was also one of the first Jewish superstars in American professional sports.[1] He garnered national attention in 1934 when he refused to play baseball on Yom Kippur, the Jewish day of atonement, even though the Tigers were in the middle of a pennant race.
