Joseph Henry (1797-1878, APS 1835), a physicist, was the first secretary and director of the Smithsonian Institution, a post he retained for over three decades. Henry was a leading experimental scientist whose contributions include several discoveries in the field of electromagnetics. He has been credited with the invention of the electromagnet and the telegraph, among other things.

Henry was born in 1797 in Albany, New York, the son of William Henry, a teamster, and his wife Ann Alexander. Around 1804 he was sent to live with his maternal grandmother and his uncle in the nearby village of Galway, where he attended a country school. Henry’s father died when he was thirteen. He subsequently returned to Albany, where he was apprenticed to John F. Doty, a watchmaker and silversmith. However, when his master’s business failed he did not complete the apprenticeship and instead contemplated a career in theater, his true passion at the time. From around 1813 to 1816 he was involved with the Green Street Theater in Albany.
