Who was the real first inventor of the light bulb?
Thomas Edison
Thomas Edison and the “first” light bulb In 1878, Thomas Edison began serious research into developing a practical incandescent lamp and on October 14, 1878, Edison filed his first patent application for “Improvement In Electric Lights”.
Did Thomas Edison invent the first light bulb?
Though Thomas Edison is credited as the man who invented the lightbulb, this revolutionary technology was in fact developed by several inventors.
Did Swan invent the lightbulb?
Joseph Swan was just one inventor who made improvements in light bulb technology. He was working as a chemist in England in the middle of the nineteenth century when he began development of a more affordable light bulb. His invention replaced the previously used platinum filaments with carbonized paper filaments.
Who invented light bulb before Edison?
Who invented the electric light? No, it wasn’t Thomas Edison. Two lesser-known inventors, Humphrey Davy and Joseph Swan (who won a patent lawsuit against Edison), both developed working electric lights well before Edison.
Who invented the lightbulb before Edison?
How Thomas Alva Edison invented bulb?
By January 1879, at his laboratory in Menlo Park, New Jersey, Edison had built his first high resistance, incandescent electric light. It worked by passing electricity through a thin platinum filament in the glass vacuum bulb, which delayed the filament from melting. Still, the lamp only burned for a few short hours.
When did Edison invent the lightbulb?
1879
Long before Thomas Edison patented — first in 1879 and then a year later in 1880 — and began commercializing his incandescent light bulb, British inventors were demonstrating that electric light was possible with the arc lamp.

What was Thomas Alva Edison first invention?
In 1869, at 22 years old, Edison moved to New York City and developed his first invention, an improved stock ticker called the Universal Stock Printer, which synchronized several stock tickers’ transactions. The Gold and Stock Telegraph Company was so impressed, they paid him $40,000 for the rights.
Who invented the lightbulb and when?
1878 – Sir Joseph Wilson Swan (1828-1914), an English physicist, was the first person to invent a practical and longer-lasting electic lightbulb (13.5 hours). Swan used a carbon fiber filament derived from cotton. 1879 – Thomas Alva Edison invented a carbon filament that burned for forty hours.
How did Swan and Edison make light bulbs?
As it happens, Swan and Edison worked from bulb designs that had been in use since the early 1800s. The general principle was, and still is, this: When electrical current flows through the bulb’s filament, the filament heats up and glows, which produces light.
Who was the first person to make electric light?
Swan, though, wasn’t the first person to make electric light. English chemist Humphry Davy connected two wires to a battery in 1809 and inserted a charcoal strip between the other ends of the wires. The strip glowed, making it the first electric lamp.
How many hours a day did Thomas Edison work on light bulbs?
He studied his competition in this endeavor which naturally included Swan, and determined that a successful light bulb needed a thinner filament that did not require a large electrical current. Edison himself worked up to 20 hours per day testing and experimenting with various designs and materials for filaments.
