(February 11, 1847 - October 18, 1931)

Thomas Alva Edison, the youngest of seven children, did poorly in school because his mind frequently wandered during lessons. After his mother began homeschooling him, Edison began to excel at learning. Untreated ear infections and a childhood bout with scarlet fever caused complete hearing loss in his left ear and partial loss in his right ear. A youthful career as a newsboy demonstrated his ability as a businessman, but his life focused when he became a telegraph operator. Most of Edison's 1,093 are improvements to the telegraph or are based on its technology. Edison applied methods of mass production to create numerous inventions. His ability to envision design technologies which would change everyday life brought him lifelong success.

Edison saved a railroad station agent's 3-year-old son from a runaway train. The child's father taught Edison how to operate a telegraph.

Edison became a Western Union telegraph operator. On the night shift, he read books and conducted scientific experiments.

Watershed Moment

In 1876, Thomas Edison opened the first industrial research laboratory in Menlo Park, New Jersey, to apply the principles of mass production to the process of invention. Nicknamed "Wizard of Menlo Park," Edison devised some of his most famous

inventions in the laboratory, including the phonograph and the filament for the incandescent light bulb.

Edison's first famous invention was the phonograph. His earliest recordings on tin foil wore out after being played several times.

Edison's first successful test of a light bulb with a carbon-based filament lasted 13 hours and 30 minutes.

Edison patented an electrical distribution system and founded the Edison Electric Illuminating Company. In 1882, the company began providing 110 volts of direct current to 59 customers in lower Manhattan.

Edison built a kinetoscope, a peephole viewer, which displayed the first motion picture films. The device became a mainstay of penny arcades.
