It was exactly 100 years ago today that Frederick Winslow Taylor died. He is considered the father of modern scientific management, the first management consultant, president of the ASME, and the first management guru. He invented and patented the first modern tool steel, designed new golf clubs, and optimized the growing of grass. He could swear like few others, but he also won the US Open tennis championships.
His work was already controversial when he died, but nobody doubts the enormous legacy he has left for industry. Without his achievements, there would be no modern manufacturing.
