Opis

Stirring accounts of four of America's greatest inventors: Robert Fulton, Eli Whitney, Samuel F. B. Morse, and Thomas Edison. Emphasis is placed on their formative years and how the skills they acquired then enabled them to meet the challenges they faced later, both in developing and manufacturing their inventions and in achieving widespread public acceptance of them.
