James Watt He created a new type of workmen capable of executing his plans, working with, and educating them often with his own hands. Only thus did he triumph, laboring mentally and physically. Watt therefore must always stand among the benefactors of men, in the triple capacity of discoverer, inventor, and constructor. from "Captured by Steam"The steam engine, steel tycoon Andrew Carnegie notes here, was one of the bases upon which his own fortune was built-so why shouldn't he write a biography of its inventor, James Watt? As Carnegie explores the life and work of "one of the finest characters that ever graced the earth," we learn as much about Carnegie's philosophies of business and personal success as we do about Watt.
