More about this marker. The bronze sculpture depicts Joseph Henry as a young man standing and holding an electromagnetic device in his proper left hand. He appears to be conducting an experiment. He stands next to a bench with a coat and hat thrown over it. Henry wears a buttoned vest and open jacket. The sculpture is mounted on a concave-shaped, tiered base. The sculpture is placed on the central, pedestal-like section which is flanked on either side by two lower panels that end in benches.
Regarding Joseph Henry. Joseph Henry (December 17, 1797 – May 13, 1878) was an American scientist who served as the first Secretary of the Smithsonian Institution. During his lifetime, he was considered one of the greatest American scientists since Benjamin Franklin. While building electromagnets, Henry discovered the electromagnetic phenomenon of self-inductance. He also discovered mutual inductance independently of Michael Faraday, though Faraday was the first to publish his results. Henry's work on the electromagnetic relay was the basis of the electrical telegraph, jointly invented by Samuel Morse and Charles Wheatstone.
In the International System of Units, the unit of inductance, the henry, is named after Joseph Henry. |
