Frank Rattray Lillie

Frank Rattray Lillie was an American zoologist and an early pioneer of the study of embryology. Born in Toronto, Ontario, Canada, Lillie moved to the United States in 1891 to study for a summer at the Marine Biological Laboratory (MBL) in Woods Hole, Massachusetts. Lillie formed a lifelong association with the laboratory, eventually rising to become its director in 1908. His efforts developed the MBL into a full-time institution.
