Sangamo Weston
was a company that made
light meters
, among much other electrical equipment. It is particularly known for the
Weston Master
series of
selenium meters
.
Weston was founded by chemist Edward Weston, who held many patents for electrical inventions, from permanent magnets through cellulose manufacturing, dynamos, arc & filament lights and the magnetic-drag speedometer to electrical measurement instruments (and even US 895218 - a fruit box!)
[1]
Weston's son, Edward Faraday Weston, applied for a U.S. patent on the first Weston Exposure meter, granted as No.2016469 in October 1935.

This was a cylindrical case with an electrical meter at one end, and an iris at the other; an adjustable scale around the meter opened and closed the iris, and showed the exposure. Sangamo was originally "Sangamo Electric Co.", in Springfield, Illinois, and set up a British subsidiary in 1921. Sangamo acquired the Weston Electrical Instrument Co. in 1936.

Since Weston were an early player in the light meter game - before film speeds were standardised, Weston had their own
film speed scales
.
