Yes, Ludwig F. Hammer established the Hammer Dry Plate Company in St. Louis, Missouri around 1890. By the 1920s the company was one of the top four plate manufacturers, along with Kodak. They made nitrate film in both sheet and roll through to the late 1930s. From 1935 onwards nitrate still negative film was progressively replaced by cellulose acetate ‘safety’ film.
