He became known as one of the fathers of photography.
Lewis Howard Latimer (September 4, 1848 – December 11, 1928) was an American inventor and patent draftsman. His inventions included an evaporative air conditioner, an improved process for manufacturing carbon filaments for electric light bulbs, and an improved toilet system for railroad cars.
In the 1960s, US inventor Robert (Bob) Kyp patented a similar in appearance but flickering "electric flame" light bulb under the name Balafire [6] as well as radiometers. His flicker bulb was used in a 7-Up commercial, [ 7 ] and the company he ran since 1964, Kyp-Go, is currently the only US manufacturer of carbon-filament bulbs.

Invented by Louis Daguerre and introduced worldwide in 1839, [2] [3] [4] the daguerreotype was almost completely superseded by 1856 with new, less expensive processes, such as ambrotype (collodion process), that yield more readily viewable images. There has been a revival of the daguerreotype since the late 20th century by a small number of ...
Official portrait of Queen Victoria, 1859. The first electronics appeared in the 19th century, with the introduction of the electric relay in 1835, the telegraph and its Morse code protocol in 1837, the first telephone call in 1876, [2] and the first functional light bulb in 1878.
Its continuous operation has largely eliminated the stresses associated with turning a light bulb on and off, the act of which causes the temperature of the bulb to increase and decrease. The bulb was made by hand, using a carbon filament (of greater thickness and strength than the tungsten filaments used in most modern lightbulbs) along with ...
The inventions were those of Albon Man and William E. Sawyer. They gave the patent rights to the company, which they had formed with a group of businessmen. It was the first company in the world formally established to provided electric lighting and was the first company organized specifically to manufacture and sell incandescent electric light ...
