Denny Galehouse was a former professional baseball player who played in the Major League Baseball (MLB) from 1934 to 1941. Born in Marshallville, Ohio, in 1905, Galehouse began his career as a pitcher for the Cleveland Indians in 1934, and he played for the team until 1940. He then played for the Boston Red Sox in 1941 before retiring from professional baseball.

Throughout his career, Galehouse had a reputation as a solid pitcher, known for his consistency and his ability to pitch complete games. He was particularly effective in 1936, when he had a 2.61 earned run average (ERA) and won 14 games for the Indians. In 1938, he won a career-high 16 games for the team.

One of Galehouse's most notable moments in the MLB occurred on August 31, 1940, when he was pitching for the Indians against the Detroit Tigers. In the ninth inning, he was ahead in the game 4-2 with two outs and the bases loaded. However, he threw a pitch that hit the Tigers' slugger, Hank Greenberg, in the head, knocking him unconscious. Greenberg had to be hospitalized, and the incident sparked outrage from fans and players alike.

After retiring from baseball, Galehouse returned to Ohio and worked as a farmer. He later became involved in politics and served as the mayor of Marshallville from 1952 to 1956. He also served as a member of the Wayne County Board of Commissioners.
