Frank B Gilbreth was one of the very first efficiency experts — he helped companies minimize the number of steps (and, therefore, the amount of time) required to get a given task done. His twelve kids were his first guinea pigs, and experienced firsthand how to become more efficient at doing everything from showering to having a tonsillectomy. Two of his children worked together to write a family memoir, Cheaper by the Dozen.
Below is a highlight reel of some of Gilbreth’s work analysis films, based on footage shot between 1910 and 1924. From this, his motion study technique was developed.
