Did Nikola Tesla invent the light bulb?
No, Tesla did not invent the light bulb. The first electric light was made in 1800 by Humphry Davy, an English scientist. Much later, in 1860, the English physicist Sir Joseph Wilson Swan (1828-1914) was determined to devise a practical, long-lasting electric light. In 1877, the American Charles Francis Brush manufactured some carbon arcs to light a public square in Cleveland, Ohio, USA. Thomas Alva Edison experimented with thousands of different filaments to find just the right materials to glow well and be long-lasting. Lewis Howard Latimer (1848-1928) improved the bulb by inventing a carbon filament (patented in 1881); Latimer was a member of Edison's research team, which was called "Edison's Pioneers." In 1903, Willis R. Whitney invented a treatment for the filament so that it wouldn't darken the inside of the bulb as it glowed. In 1910, William David Coolidge (1873-1975) invented a tungsten filament which lasted even longer than the older filaments.
