Lillian Moller Gilbreth

Born in Oakland, California, Lillian Moller Gilbreth studied literature and psychology at the University of California and went on to earn a doctorate in psychology. She became one of the most influential figures in industrial engineering by combining scientific management with a strong interest in how people actually think, feel, and work.

Working closely with her husband, Frank B. Gilbreth, she helped develop motion-study methods that aimed to reduce wasted effort and improve productivity. After his death, she continued the work on her own, building a remarkable career as a consultant, teacher, and inventor while raising a large family.

Gilbreth is often remembered both as a serious scholar and as the real-life mother behind the family story that inspired Cheaper by the Dozen. She also designed practical household improvements and became widely recognized as a trailblazer for women in engineering and management.
