Cheaper by the Dozen (1948) and Belles on Their Toes (1950), written by two of their children (Ernestine and Frank Jr.) tell the story of their family life and describe how time-and-motion studies were applied to the organization and daily activities of their large family. Both books were later made into feature films.
