Hans Spemann


German embryologist who was awarded a Nobel Prize in Physiology or Medicine in 1935 for his discovery of the effect now known as embryonic induction, an influence, exercised by various parts of the embryo, that directs the development of groups of cells into particular tissues and organs. Spemann gave the Nazi salute during his Nobel Prize speech.

For his PhD thesis under Theodor Boveri, Spemann studied cell lineage in the parasitic worm Strongylus paradoxus, for his teaching diploma, the development of the middle ear in the frog. Spemann advocated a holistic approach to biology.

His theory of embryonic induction by organisers is described in his book Embryonic Development and Induction (1938). He died of heart failure on 12 September 1941 at age 72 in Freiburg, Germany.
