Frank Rattray Lillie

Died 5 Nov 1947 at age 77 (born 27 Jun 1870).American zoologist and embryologist, known for his discoveries concerning the fertilization of the egg (ovum) and the role of hormones in sex determination. In 1914, Lillie hypothesized the existence of a substance, fertilizin, in the jelly coat of eggs which causes sperm cells to clump together. In 1916, he demonstrated the role of sex hormones in freemartinism. His embryological investigations reached into all aspects of cellular and embryonic development. He is best known for his dedicated efforts in shaping the Marine Biological Laboratory and the Oceanographic Institute at Woods Hole, Mass. He wrote The Development of the Chick (1908), a leading embryology text, and The Woods Hole Marine Biological Laboratory (1944).Image: 28-hour chick embryo.
