Harold Philip "Steve" Partenheimer (August 30, 1891 – June 16, 1971) was an American baseball player and rubber industry executive and innovator.

Partenheimer played college baseball for Amherst College and then appeared in one game Major League Baseball with the Detroit Tigers on June 28, 1913.

He later spent more than 50 years working in the rubber industry and was credited with developing a "run flat" tire used on American military vehicles.

Early years

Partenheimer was born in Greenfield, Massachusetts, in 1891.^[1] He attended Amherst College for four years from 1909 to 1913 and was captain of the varsity baseball team as a senior.^[2] He was named to Amherst's all century baseball team in 1959.^[3]

Professional baseball

On June 20, 1913, Frank Navin, owner of the Detroit Tigers, announced that he had signed Amherst third baseman Partenheimer who would report shortly for a tryout.^[4] On June 28, in his one and only Major League game, Partenheimer played third base, collected three assists, and committed one error. At bat, he was hit by a pitch, but failed to register a hit, in three plate appearances.^[1]

Less than one week after his major league debut, the Tigers assigned Partenheimer to Utica in the New York State League. At the time, the Detroit Free Press wrote that he was not ready for "big time" baseball, "appears to be a good fielder, but shows poor form at bat."^[5] After his brief stint with the Tigers, Partenheimer played three years in New York State League.^[2]

After retiring from baseball, Partenheimer obtained a doctoral degree from Columbia University and worked for more than 50 years in the tire business. He held positions with the Fisk Rubber Company, B. F. Goodrich Co., and starting in 1941 Mansfield Tire & Rubber Company. He became the director of research and development for Mansfield and was credited with developing a "run flat" tire that allowed military combat vehicles to run at high speed even after being punctured by bullets or shellfire.^[6][7]

Partenheimer also remained active in baseball, having affiliations with Mansfield Little League, the Gordon Drug Aces, the Akron Jays, Sohio Athletic Club and the Killian Celtics.^[6][2]
