At a time when women were standard fixtures in the home and barely accepted in many professions, Gilbreth excelled in both spheres, concurrently winning honors as Engineer of the Year and Mother of the Year. This accessible, engaging introduction to the life of Lillian Gilbreth examines her pivotal role in establishing the discipline of industrial psychology, her work as an engineer of domestic management and home economics, and her role as mother of twelve children- made famous by the book, and later movie, Cheaper by the Dozen . This book examines the life of an exceptional woman who was able to negotiate the divide between the public and domestic spheres and define it on her terms.
