biography

eatly life:

Thomas Alva Edison was born on February 11, 1847, in Milan, Ohio. He was the seventh and last child born to Samuel Edison Jr and Nancy Elliott Edison, and would be one of four to survive to adulthood. Thomas Edison received little formal education, and left school in 1859 to being working on the railroad between Detroit and Port Huron, Michigan, where his family then lived. During the Civil War, Edison learned the emerging technology of telegraphy, and travelled around the country working as a telegrapher. He had developed serious hearing problems

With the development of auditory signals for the telegraph, Edison was at a disadvantage, and he began to work on inventing devices that would help make things possible for him despite his deafness (including a printer that would convert the electrical signals to letters). In early 1869, he quit telegraphy to pursue invention full time.

Edison’s Innovations with Electric Light:

In 1878, Edison focused on inventing a safe, inexpensive electric light to replace the gaslight–a challenge that scientists had been grappling with for the last 50 years. With the help of prominent financial backers like J.P. Morgan and the Vanderbilt family, Edison set up the Edison Electric Light Company and began research and development. He made a breakthrough in October 1879 with a bulb that used a platinum filament, and in the summer of 1880 hit on carbonized bamboo as a viable alternative for the filament, which proved to be the key to a long-lasting and affordable light bulb.

pictures of his inventions

the bulb

iThomas Edison used this carbon-filament bulb in the first public demonstration of his most famous invention—the light bulb, the first practical electric incandescent lamp. The light bulb creates light when electrical current passes through the metal filament wire, heating it to a high temperature until it glowsth

His first invention was an electric vote recorder.

“our greatest weakness lies in giving up..."

“Just because something doesn't do what you planned it to do, doesn't mean it's useless.”

“If we did all the things we are capable of, we would literally astound ourself”
