Gravestone of Zoltán Bay (Gyulavári, Hungary)Bust and plaque commemorating Zoltán Bay in Újpest, Hungary. The plaque on the right lists his achievements.
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, whose research staff included Zoltán Bay, along with Tivadar Millner, Imre Bródy, György Szigeti, Ernő Winter, and many others.[1]
György Szigeti worked together with Zoltán Bay on metal-vapor lamps and fluorescent light sources. They received a U.S. patent on "Electroluminescent light sources" which were made of silicon carbide; these light sources were the ancestors of light-emitting diodes (LEDs).[1]
In 1955, Zoltán Bay became head of the Department of Nuclear Physics in the National Bureau of Standards (NBS, called today NIST), where he measured the velocity and frequency of light by a previously unknown measurement method.[2][failed verification] As a result of Bay's research, the 1983 conference of the International Weights and Measures Bureau accepted, as a standard, the definition of a meter (metre)[3] as recommended by Zoltán Bay.
