  • György Szigeti (29 January 1905 – 27 November 1978), 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 diodes (LEDs). (en)
