Joseph Henry Unveils Large Galvanic Battery
At Princeton's commencement, Joseph Henry exhibits the large galvanic battery he had begun constructing in early 1833. It would become one of the most important scientific instruments in Henry's Princeton laboratory, and its completion was an essential first step for the resumption of his electrical research. It is described in Henry's "Contributions I: Battery," a paper read before the American Philosophical Society in January 1835. In 1846, Henry would become the first Secretary of the Smithsonian Institution.
