Bertram is a German manufacturer of photographic products, best known for its Bewi light meters.
Leiner & Bertram was started in 1919 by Ludwig Leiner and Ernst Bertram, as a workshop making camera shutters. Leiner left in 1928, and Paul Will took over the company in the same year, adding the manufacture of light meters. The first model sold (in 1930), the Bewi, was designed by Ernst Bertram (1886–1974); the Elektro-Bewi of 1935 was designed by Ernst's brother Wilhelm Bertram (1903–1990).
At some time in the mid-century, Paul Will left and Wilhelm Bertram moved in, thereby forming E. & W. Bertram.
