This photograph was distributed during the Great Depression when Gilbreth chaired the Women's Division of the President's Emergency Committee for Employment, working on how to assist needy families in buying health protection with their food money. Lillian Evelyn Moller Gilbreth (May 24, 1878 - January 2, 1972) was an American psychologist and industrial engineer. One of the first working female engineers holding a Ph.D., she is arguably the first true industrial/organizational psychologist. She and her husband Frank Bunker Gilbreth were efficiency experts who contributed to the study of industrial engineering in fields such as motion study and human factors. The books Cheaper by the Dozen and Belles on Their Toes (written by their children Ernestine and Frank Jr.) are the story of their family life with their twelve children, and describe how they applied their interest in time and motion study to the organization and daily activities of such a large family. During her career, Gilbreth received numerous awards and honors, including 23 honorary degrees from such schools as Princeton University, Brown University, and the University of Michigan. In 1965, she became the first woman elected to the National Academy of Engineering. She died in 1972 at the age of 93.
