Wie is de uitvinder van de gloeilamp?

Nee, ik ben het niet eens met de Göbel-antwoorden. Die heeft over dit onderwerp een rechtszaak verloren.

De uitvinding van de gloeilamp wordt vaak toegeschreven aan Thomas Alva Edison. Edison was echter slechts een van de velen die bijdroegen aan de ontwikkeling van een praktisch middel om met elektriciteit licht te genereren. De reeds bestaande koolstofbooglamp was ondanks het helderwitte licht niet praktisch genoeg. In 1801 experimenteerde Humphry Davy al met een gloeiende platinadraad, die echter onmiddellijk verbrandde. In 1854 slaagde Heinrich Göbel erin de eerste echte gloeilamp te maken. Zijn gloeilamp bestond uit een verkoolde bamboevezel in een vacuümgezogen eau-de-colognefles. Hij kon de fles vacuüm trekken door deze te vullen met kwik en hem daarna leeg te laten lopen. Door het vacuüm kon de bamboevezel niet verbranden. Göbels lamp brandde 400 uur. Edison vroeg 25 jaar later octrooi aan op een zelfde soort lamp. Göbel betwistte het patent voor de rechtbank en kreeg in 1893 zijn gelijk. Hij overleed echter in hetzelfde jaar.

Toen Edison 25 jaar later de gloeilamp patenteerde, bestreed Göbel dat met succes voor de rechtbank.

In a suit filed by rivals seeking to get around Edison's lightbulb patent, German-American inventor Heinrich Göbel claimed he developed the first light bulb in 1854: a carbonized bamboo filament, in a vacuum bottle to prevent oxidation, and that in the following five years he developed what many call the first practical light bulb. Lewis Latimer demonstrated the bulbs Göbel had purportedly built in the 1850s had actually been built much later, and found the glassblower who had constructed the fraudulent exhibits. In a patent interference suit in 1893, the judge ruled Göbel's claim "extremely improbable."

A few months after a court decision established the Edison's priority, Göbel died of pneumonia. He was buried in the Green-wood Cemetery in Brooklyn. New York.

Wat was de naam van de man die samen met Peary als eerste de Noordpool betrad?

(Dat Peary's claim op het ogenblik onder vuur ligt is voor de vraag verder niet relevant)

We gaan hier vragen stellen over dat soort onweetjes. Het goede antwoord moet gestaafd worden met een betrouwbare bron, liefst een link. Degene die het goede antwoord geeft stelt tevens de volgende vraag, enzovoort.

En ik heb nog steeds niet de naam gezien die ik wens......

Sir Joseph Wilson Swan (October 31, 1828 – May 27, 1914) was an English physicist and chemist, most famous for the invention of the light bulb.

Swan received a British patent for his device in 1878, about a year before Thomas Edison. Swan had reported success to the Newcastle Chemical Society and at a lecture in Newcastle upon Tyne in February 1879 he demonstrated a working lamp. Starting that year he began installing light bulbs in homes and landmarks in England. His house Underhill on Kells Lane in Low Fell, Gateshead was the first in the in the world to have working light bulbs installed. In 1881 he had started his own company, The Swan Electric Light Company, and started commercial production.

In America Edison had been working on copies of the original Swan patent, trying to make them more efficient. Though Swan had beaten him to this goal, Edison obtained patents in America for a fairly direct copy of the Swan light{[fact}}, and started an advertising campaign which claimed that he was the real inventor[citation needed]. Swan, who was less interested in making money from the invention{[fact}}, agreed that Edison could sell the lights in America while he retained the rights in Britain[citation needed].

[edit] Ediswan

In 1883 the Edison & Swan United Electric Light Company was established. Known commonly as "Ediswan" the company sold lamps made with a cellulose filament that Swan had invented in 1881. Variations of the cellulose filament became an industry standard, except with the Edison Company. Edison continued using bamboo filaments until the 1892 merger that created General Electric, and that company then shifted to cellulose.

In 19th century Dundee, later to be dubbed the "City of Discovery", Lindsay's talents flourished. In 1835 he demonstrated constant electric light, whereby he could "read a book at a distance of one and a half foot". Regrettably, he seems to have done little to establish his claim or to develop the device, which Thomas Edison finally claimed as his own over 40 years later.
