Hungarian physicist and engineer (1905–1978)

György Szigeti (29 January 1905 – 27 November 1978),[1] 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.[1] The head of that laboratory was Ignácz Pfeiffer (1867–1941), whose research staff included Szigeti, along with Zoltán Bay (1900–1992), Tivadar Millner, Imre Bródy (1891–1944), Ernő Winter (1897–1971), and others.[1]

Szigeti worked together with Zoltán 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 diodes.[1]
