The “Atelier Ruhmkorff J. Carpentier, Ingr Constr à PARIS” inscription on the brass bar of this large and handsome Melloni bench refers to Jules Carpentier, a French instrument maker who bought the Ruhmkorff firm in 1877, and arranged with James W. Queen & Co. to handle the American market. At the International Electrical Exhibition held in Philadelphia in 1884, Queen showed a “Melloni’s Apparatus” that was described as a “finely constructed piece of apparatus for delicate experiments in heat, with between thirty and forty accessories” that “was manufactured by Carpentier, of Paris, and was contained in a very neat and compact case for safe keeping and transportation.”
This example came from the Packer College Institute, a school that was established as the Brooklyn Female Academy, in Brooklyn Heights, New York, in 1845.
