Hans Adolf Eduard Driesch (28 October 1867 – 17 April 1941) was a German biologist and philosopher from Bad Kreuznach. He is most noted for his early experimental work in embryology and for his neo- vitalist philosophy of entelechy.
Jan 1, 2012 · Driesch's 1891 to 1892 experiments ultimately led him to conclude that embryonic cells are totipotent in their early stages of development, each with the capacity to become a full organism. But his discovery that separated single cells could develop into whole embryos was not accepted by Roux.
Nov 1, 2007 · In 1891 Driesch performed an important experiment: the separation of developing sea urchinblastomeres. He discovered that if the sea urchin blastomeres were separated at the 2–cell stage, two complete but smaller than normal sea urchins would develop.

German biologist and master experimenter who was one of the leading practitioners of Entwicklungsmechanik. When he discovered that almost any cell had the ability to become an embryo, however, he set out to destroy Entwicklungsmechanik, challenging the mechanistic view and reviving Vitalism Theory.
