Thomas J. Watson

Thomas John Watson, Sr. (February 17, 1874 - June 19, 1956) was the American president of International Business Machines (IBM), who oversaw that company's growth into an international force from the 1920s to the 1950s. Watson developed IBM's effective management style and turned it into one of the most effective selling organizations yet seen, based largely around punched card tabulating machines. A leading self-made industrialist, he was one of the richest men of his time and was called the world's greatest salesman when he died in 1956
