who was the scientist that invented electric bulb
Thomas Alva Edison
title: Henry Woodward (inventor) text: necessary components to make the first practical electric light bulb. What is known about Woodward's discovery is that it was patented in Canada and the United States prior to a patent being granted to Edison and it is known that the patent for the Canadian discovery was purchased by Edison when he was making his original investigations and before he obtained his patent. Ricketts, Bruce. The First Electric Light Bulb Henry Woodward (inventor) Henry Woodward was a Canadian inventor and a major pioneer in the development of the incandescent lamp. On July 24, 1874, Woodward and his partner, Mathew Evans, title: Franjo Hanaman text: Franjo Hanaman Franjo Hanaman (June 30, 1878 in Drenovci, Slavonia, Kingdom of Croatia-Slavonia, Austria-Hungary – January 23, 1941 in Zagreb, Kingdom of Yugoslavia - Croatia today) was a Croatian inventor, engineer, and chemist, who gained world recognition for inventing the world's first applied electric light-bulb with a metal filament (tungsten) with his assistant Alexander Just, independently of his contemporaries. They were granted the Hungarian Patent #34541 on December 13, 1904 in Budapest. His invention of tungsten filament was also applied in improving early diodes and triodes. Franjo Hanaman was born to a Croatian family as a second child of father title: Technology brokering text: class behind the Sam Adams brand. The Light Bulb On December 31, 1879, Edison first displayed his most popular invention. It was the first "practical incandescent, electric lamp. This is a perfect example of Thomas Edison leveraging technology brokering. Edison was not the first person to invent electric light. J.W. Starr filed a patent for an incandescent bulb in 1854. That was 30 years before Edison began working on the light bulb we know today. When Edison first started testing incandescent lamps, the arc light was being used for lighting streets and also for various other applications. When Edison began title: Franjo Hanaman text: Gjuro Hanaman and Emilija Mandušić.

Franjo Hanaman was born to a Croatian family as title: Incandescent light bulb text: involving the use of carbon filaments. He died shortly after obtaining the patent, and his invention was never produced commercially. Little else is known about him. In 1851, Jean Eugène Robert-Houdin publicly demonstrated incandescent light bulbs on his estate in Blois, France. His light bulbs are on display in the museum of the Château de Blois. In 1859, Moses G. Farmer built an electric incandescent light bulb using a platinum filament. He later patented a light bulb which was purchased by Thomas Edison. In 1872, Russian Alexander Lodygin invented an incandescent light bulb and obtained a Russian patent in 1874.
