With only three months of formal education, Thomas Edison grew up to be one of the most successful inventors of all time. Applying scientific principles to practical use, he made scores of inventions and held over thirteen hundred patents, from improvements on the telegraph and phonograph to the development of the incandescent lamp and a whole system for distributing electricity. Edison's rise from humble beginnings and his unceasing struggle to overcome obstacles illustrate the spirit of America. His genius and investigative methods shaped the future and continue to influence new generations.
