Usage conditions apply
The "Locatelli et C à Paris" inscription on this oil lamp is that of Louis-Melchior-Balthazar Locatelli, a French engineer who, in 1828, patented a new system of lighting. Scientists used Locatelli lamps for studying radiant heat at an early day. This example came from the Smithsonian Castle, and may have been used by Joseph Henry, the physicist who served as founding Secretary of the Institution.
