Mother of Modern Management and America’s First Lady of Engineering
Eleven years before receiving her Ph.D., Lillian married Frank Gilbreth. Together, they had 12 children. Two of the children went on to write two books, “Cheaper by the Dozen” and “Belles on Their Toes,” about their life in the Gilbreth household. Frank and Lillian devoted themselves to finding the “one best way” to perform any task in order to increase efficiency and productivity in industry. These studies are called time and motion studies.
In June 1924, Frank died suddenly of a heart attack. Lillian continued the work they had begun, writing four books and teaching industrial engineering courses at various schools, including Purdue, Bryn Mawr, and Rutgers. She was the first person to integrate psychology into concepts of industrial management.
During the Great Depression, President Hoover asked her to join the Emergency Committee for Unemployment. While on this committee, she created a successful nationwide program, “Share the Work,” that created many new jobs. During World War II, Lillian worked as a consultant for the government. She oversaw the conversion of factories to military bases and war plants. Lillian is credited with many inventions. These inventions include the foot-pedal trash can and refrigerator door shelves.
