He opened a photography studio and developed a stereopticon machine that combined sound with images projected on a screen. Bernard lived to be one hundred years old. The Oscar C. Bernard photographs, PH047, consist of glass plate negatives, magic lantern slides, and sheet negatives. The collection was donated by Leon C. Metz.
