Thomas Edison and his lab associates, called "Muckers," conducted thousands of experiments to develop the electric light bulb. To make it functional, each step required the invention of a new component, from vacuumed and sealed glass bulbs to switches, special types of wire and meters.

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. At age 12, he developed hearing loss—he was reportedly deaf in one ear, and nearly deaf in the other—which was variously attributed to scarlet fever...
From 1870 to 1875, Edison worked out of Newark, New Jersey, where he developed telegraph-related products for both Western Union Telegraph Company (then the industry leader) and its rivals. Edison’s mother died in 1871, and that same year he married 16-year-old Mary Stillwell. Despite his prolific telegraph work, Edison encountered financial diffic...
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 Vanderbiltfamily, Edison set up the Edison Electric Light Company and began research and development. He made...
Edison’s wife, Mary, died in August 1884, and in February 1886 he remarried Mirna Miller; they would have three children together. He built a large estate called Glenmont and a research laboratory in West Orange, New Jersey, with facilities including a machine shop, a library and buildings for metallurgy, chemistry and woodworking. Spurred on by ot...

After devising a commercially viable electric light bulb on October 21, 1879, Edison developed an electric "utility" to compete with the existing gas light utilities. [73] On December 17, 1880, he founded the Edison Illuminating Company , and during the 1880s, he patented a system for electricity distribution .
Thomas 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 glows.
The inventor Thomas Alva Edison (in the USA) experimented with thousands of different filaments to find just the right materials to glow well and be long-lasting. In 1879, Edison discovered that a carbon filament in an oxygen-free bulb glowed but did not burn up for 40 hours.
