Rhamstine (often written "J. Thos. Rhamstine") was founded in Detroit 1921 by John Thomas Rhamstine (1892-1975). The company manufactured several products, mostly radio related, like rheostats and amplifiers. In 1931 Rhamstine manufactured presumably the world's first photoelectric light meter, a selenium meter called Electrophot DH, and continued making several other models before the Second World War. After the war John Rhamstine sold the company, and its name was changed to Adair-Rhamstine Company, that kept on manufacturing the model 14A until the beginning of 1950's. [1]
