About This Book
A historical survey and collection of biographies that traces the technical and personal development of machine-tool making in England and the United States. It profiles pioneering craftsmen and engineers—Maudslay, Wilkinson, Bramah, Nasmyth, Whitworth, Eli Whitney and American firms such as Colt, Pratt & Whitney, Robbins & Lawrence and Brown & Sharpe—while explaining key inventions (lathe, planer, gearing, interchangeability) and regional centers of manufacture. Chapters combine technical description, industrial context, and firm histories to show how toolmaking practices enabled mass production and shaped later engineering, concluding with appendices and a partial bibliography.
