Ernő Winter (15 March 1897 – 2 June 1971)[1] was a Hungarian engineer who developed barium lamps.[2] Working at Tungsram, Ernő Winter, along with others, co-developed tungsten technology for the production of more reliable and longer-lasting coiled-filament lamps.[2]
In 1923 at Tungsram Ltd., a research laboratory was established for improving light sources, mainly electric bulbs.[1] The head of that laboratory was Ignác Pfeifer (1867 - 1941), whose research staff included Ernő Winter, along with Tivadar Millner (1899 - 1988), Zoltán Bay (1900 - 1992), Imre Bródy (1891 - 1944), György Szigeti (1905 - 1978), and many others.[1]
