Where did Joseph Swan go to school?
Swan lived at Underhill, Low Fell, Gateshead, a large house on Kells Lane North, where he conducted most of his experiments in the large conservatory. The house was later converted into Beaconsfield School, a private fee-paying, grant-aided co-educational grammar school.
Who is Sir Joseph Wilson Swan and why is he important?
Sir Joseph Wilson Swan (31 October 1828–27 May 1914) was an English physicist and chemist who was well known because he created the incandescent light bulb, about a year before Thomas Edison. His house was the first in the world to be lit by electric light bulbs.
How long did Joseph Swan’s light bulb last?
about 13½ hours
Swan’s electric lamp deposited a dark layer of soot inside its inner surface, obscuring the light. Swan experimented with a filament of carbonized paper, but it burned out quickly. The bulb lasted just about 13½ hours. Still, that was long enough to signal that there could be a real future for this invention.
What things did Joseph Swan invent?

Joseph Swan/Inventions
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.
What did Joseph Swan use to improve the lightbulb?
Why then is Edison generally credited (outside Britain) with inventing the light bulb? Like other early inventors, Swan used a carbon rod with low electrical resistance in his lamp. Due to the relationship between resistance and current, a low resistance element required lots of current in order to become hot and glow.
Why was Joseph Swan knighted?
His pioneering experiments with photography and electric lighting were revolutionary. Swan was knighted in 1904 for his work. He died on May 27, 1914, in Warlingham Surrey. With his new lightbulb Swan made a name for himself and the city of Newcastle as the home of many world firsts.
Who was first swan or Edison?
In reality, light bulbs used as electric lights existed 50 years prior to Thomas Edison’s 1879 patent date in the U.S. Additionally, Joseph Swan, a British inventor, obtained the first patent for the same light bulb in Britain one year prior to Edison’s patent date.
