Leopold von Ubisch (1886–1965)^[1] was a German paleontologist who in 1954 surgically removed the nucleus from sea urchin eggs, to confirm an 1899 experiment by Theodor Boveri.^[2]

He was an early supporter of the theory of continental drift.^{[3] [4]}

Von Ubisch was a professor of zoology at the University of Münster from 1927 to 1935, when he was fired because his mother was Jewish.^[5] In 1945 he declined an offer to return to his chair.^[5]
