who designed a shovel to handle 21 pounds of pig iron
Frederick Winslow Taylor Taylor thought that by analyzing work, the "one best way" to do it would be found. He is most remembered for developing the stopwatch time study, which combined with Frank Gilbreth's motion study methods, later became the field of time and motion study. He broke a job into its component parts and measured each to the hundredth of a minute. One of his most famous studies involved shovels. He noticed that workers used the same shovel for all materials. He determined that the most effective load was 21Â½ lb, and found or designed shovels that for each material would scoop up that amount. He was generally unsuccessful in getting his concepts applied, and was dismissed from Bethlehem Iron Company/Bethlehem Steel Company. Nevertheless, Taylor was able to convince workers who used shovels and whose compensation was tied to how much they produced to adopt his advice about the optimum way to shovel by breaking the movements down into their component elements and recommending better ways to perform these movements. It was largely through the efforts of his disciples (most notably H.L. Gantt) that industry came to implement his ideas. Moreover, the book he wrote after parting company with the Bethlehem company, Shop Management, sold well.
