Career
Berkenstock played in just one pro league game: the game that decided the first professional baseball championship in the United States, in 1871. He was Jewish.
Exactly when Berkenstock first took up the game of baseball is unknown. The National Association of Base Ball Players, the first organized amateur league, was not founded until 1857, when he was 26.
According to Marshall Doctorate. Wright"s book The National Association of Base Ball Players, 1857-1870, Berkenstock debuted with the Athletic Club of Philadelphia (the original team of this name, and not related to the American League team that now plays in Oakland) in 1863, when he was 32.
