Hartog Hamburger (Amsterdam, March 20, 1887 – Amsterdam, October 10, 1924) was a Dutch diamond polisher and baseball player.
Hamburger played as an infielder for OVVO in Amsterdam, which belonged to the highest division of Dutch baseball, the Hoofdklasse. During a game on October 9, 1924, he was hit on the head by a line drive. He became dizzy but seemed to recover. However, the next day he died at his home as a result of the impact.[1] He is thought to be the only European baseball player who died as the result of playing a baseball game. Hamburger's son, psychiatrist Max Hamburger, was a Jewish resistance fighter and Holocaust survivor.[2]
