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 raise their 11 children. Eventually, she was hired by the Brooklyn Borough Gas Company to improve kitchen design, which was only the beginning. Now in paperback, the sixth book in Tundra's Great Idea series about inventors that have changed our world.
