Frank Bunker Gilbreth was an American engineer, consultant, and author known as an early advocate of scientific management and a pioneer of time and motion study, and is perhaps best known as the father and central figure of Cheaper by the Dozen.

Scientific management is a theory of management that analyzes and synthesizes workflows. Its main objective is improving economic efficiency, especially labor productivity. It was one of the earliest attempts to apply science to the engineering of processes to management. Scientific management is sometimes known as Taylorism after its pioneer, Frederick Winslow Taylor.
