Lillian Evelyn Gilbreth

Trained as a psychologist, she collaborated with her husband, Frank Gilbreth, to study the movements required to accomplish particular tasks. They applied these studies to industrial settings, becoming pioneers in ergonomics and consultants to corporations across the nation and around the world. She later taught at several universities, and wrote books on applying ergonomics in the home. Besides this, she and Frank raised 12 children. The family was the subject of the book and subsequent movies, Cheaper by the Dozen.
