Manufacturer of photo tubes Visitron and Neotron for mechanical television in the 1920/1930s.

Advertisements in 1930 gave different addresses, apparently arbitrarily switching between numbers 180, 1802, 1807 and 1810 Grace St.

The company later went on to also produce measuring equipment, relays and (in the 1960s) servo motors.

History:

The phototube division (Visitron) was acquired by the Rauland Corporation in 1944.
See Visitron (Rauland).

This manufacturer was suggested by Wolfgang Scheida.
