Born into a life of privilege in 1878, Lillian Moller Gilbreth put her pampered life aside for one of adventure and challenge. She and her husband, Frank, became efficiency experts by studying the actions of factory workers. They ran their home efficiently, too. When Frank suddenly died, Lillian was left to her own devices to raise their eleven children. Eventually, she was hired by the Brooklyn Borough Gas Company to improve kitchen design, which was only the beginning.

Lillian Gilbreth was the subject of two movies (Cheaper by the Dozen and Belles on Their Toes), the first woman elected to the National Academy of Engineering, and the first female psychologist to have a U.S. postage stamp issued in her honor. A leading efficiency expert, she was also an industrial engineer, a psychologist, an author, a professor, and an inventor.
