Oskar Heinroth (1 March 1871 31 May 1945) was a German biologist who was one of the first to apply the methods of comparative morphology to animal behavior, and was thus one of the founders of ethology. He worked, largely isolated from most other scientists of the period, at the Berlin Aquarium where he took care of fishes, reptiles and birds, especially waterfowl before he was murdered by Soviet occupying police agents shortly after WW2.
