Ernestine Gilbreth Carey was born on April 5, 1908, in New York City. She was one of the twelve children of Lillian Moller Gilbreth and Frank Bunker Gilbreth, both recognized pioneers in industrial efficiency studies. Her upbringing in such a dynamically experimental household, focused on efficiency and scientific management, played a significant role in shaping her worldview and, subsequently, her writing. This marked the beginning of a journey that would culminate in her becoming a celebrated author who would bring her unique childhood experiences to life in her later works, particularly in the classic memoir "Cheaper by the Dozen."
