Biography
In the time period 1907-1908 many articles appeared in the literature regarding an incandescent lamp called the "Helion". The workers who spent much time developing that lamp were physics Professor Herschel C. Parker and Electrical Engineer Walter G. Clark. Much of this work was performed in Professor Parker's laboratory at Columbia University. The lamp was called the Helion, from the Greek word "helios", because its spectrum was closer to that of the sun than was the spectrum of the carbon filament lamp.
The Helion lamp had a selective radiator filament which was made with a carbon filament core onto which silicon was deposited. The lamp was much more efficacious than the carbon filament lamp. Lamps were made for a short period of time13 - apparently by the Parker-Clark Electric Company. It is assumed that the lamp did not become a commonplace item because the metal filament lamps, such as tantalum, osmium and tungsten were being introduced at the same time.
The appearance of the 115-volt Helion lamp was very similar to that of the Edison oval anchored filament carbon lamp.
Herschel Clifford Parker was born on 9 July 1867 in Brooklyn, New York. He passed away in 193115.
