"Optical industry in Rochester (N.Y.)"
Gassner and Marx was founded by Benjamin Marx, James Rothschild and Henry Gassner. They manufactured the Day Plate Camera on which they had received a patent in 1898. It had to be loaded with a set of 3¼ x 4¼-inch glass plates which were packaged in a strip of black paper, thus allowing daylight loading of the camera.
