Dr. Irving Langmuir (1881-1957) holds a developmental pliotron tube used in 1914 for experimental radio telephone communication, which led to the development of commercial radio broadcasting. Langmuir pioneered work in electric lighting, developing a gas-filled incandescent lamp and coiled tungsten filament. In 1932 his surface film studies earned him the Nobel Prize in Chemistry, the first industrial scientist to receive the honor.
