DuMont Laboratories was an American television equipment manufacturer. The company was founded in 1931, in Upper Montclair, New Jersey, by inventor Allen B. DuMont. Among the company's developments were long-lasting cathode ray tubes that would be used for television. Another product developed by the lab was a DuMont invention, the magic eye tube.[1]


In 1938, the company began manufacturing televisions at a factory in nearby Passaic, New Jersey.[1]:191 To sell televisions, DuMont began the DuMont Television Network in 1946, one of the earliest television networks. Later on, they manufactured cameras and transmitters for television. DuMont equipment was known for its high quality. The main CRT factory was in Clifton, NJ close by on Bloomfield Ave. It made black and white TV tubes as well as instrumentation and military fire control tubes in the early 50's

In 1956, DuMont shuttered the network and sold what remained of his television operations to John Kluge, who renamed the network Metromedia.[1]:38 DuMont's partner, Thomas T. Goldsmith, remained on Metromedia's board of directors until the stations were sold to the Fox Television Stations Group.

DuMont sold his television manufacturing division to Emerson Radio in 1958, and sold the remainder of the company to Fairchild Camera in 1960.[1]:38 Fairchild later developed semiconductor microchips. Robert Noyce, founder of Intel, originally worked for DuMont as an engineer.

DuMont televisions outside the United States were assembled under license in Montreal, Canada by Canadian Aviation Electronics, currently a manufacturer of flight simulator and pilot training equipment.
