György Szigeti
also known as Gyorgy Szigeti, was a Hungarian
physicist
and engineer
who developed tungsten
lamps.
In 1923 at Tungsram Ltd.
, a research laboratory was established for improving light sources, mainly electric bulbs. The head of that laboratory was Ignácz Pfeiffer (1867-1941), whose research staff included Szigeti, along with Zoltan Bay (1900-1992), Tivadar Millner
, Imre Bródy
(1891-1944), Ernő Winter
(1897-1971), and others.
Szigeti worked together with Zoltan Bay on metal-vapor lamps and fluorescent light sources. They received a U.S. patent on "electroluminescent light sources" that were made of silicon carbide; these light sources were the ancestors of light-emitting diode

who developed tungsten
Tungsten
Tungsten , also known as wolfram , is a chemical element with the chemical symbol W and atomic number 74.A hard, rare metal under standard conditions when uncombined, tungsten is found naturally on Earth only in chemical compounds. It was identified as a new element in 1781, and first isolated as...

Tungsram
Tungsram is a Hungarian manufacturer of light bulbs and vacuum tubes since 1896. General Electric, in 1990, acquired majority share in one of Hungary's largest, oldest, and internationally most prestigious firms, the light-source manufacturer Tungsram. Over the past six years GE has invested $600...
