Yves Delage

Died 7 Oct 1920 at age 66 (born 13 May 1854).French zoologist known for his research and elucidation of invertebrate physiology and anatomy. He also discovered the equilibrium-stabilizing function of the semicircular canals in the inner ear (1886). Delage studied circulation in crustaceans, made important discoveries in the embryology of sponges (such as Sacculina), and investigated the nervous system of barnacles (Peltogaster) and flatworms (Convoluta). He developed a method for culturing sea urchins following artificial fertilization of the eggs with chemicals. Turning late in his career to more general problems of biology, he considered how life in individual organisms and species is manifested through cytoplasm, and he examined mechanical problems of the cell.
