Voltameter

notes: label: Description
content: This volatameter (or electrolysis apparatus) came from the Smithsonian Instrument Room, and was probably purchased by Joseph Henry, the physicist who served as the founding Secretary of the Institution. It is often termed a Hofmann Voltameter, in reference to the German chemist, August Wilhelm von Hofmann (1818-1892). Hofmann probably did not invent or design the apparatus, but he did make it popular. Visitors to the Special Loan Collection of Scientific Apparatus, held in London in 1876, could see 16 pieces of Hoffman’s apparatus—many of which were used for electrolysis demonstrations—that were manufactured by Warmbrunn, Quilitz & Co., in Berlin. The inscription on this example reads "Casella, London".
