Theodore Roosevelt Signed Program 1899 Joseph Henry Centennial

Description: A scarce four-page program for the Joseph Henry Centennial Celebration with two original tipped-on photographs. Many of the participants have signed including Governor Theodore Roosevelt, Verplanck Colvin (Adirondack topographical engineer & author), Albany Episcopal Bishop Wm. Croswell Doane and Albany historian/author Cuyler Reynolds. Overall 8 1/2" x 11". Henry (1797-1898) was born in Albany, NY in 1797, attended the Albany Academy where the Centennial Celebration was held, and was appointed Professor of Mathermatics. Joseph Henry was an American scientist who served as the first Secretary of the Smithsonian Institution and invented electromagnets. 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 make the discovery and publish his results. Henry developed the electromagnet into a practical device. He invented a precursor to the electric doorbell (specifically a bell that could be rung at a distance via an electric wire, 1831) and electric relay (1835). The SI unit of inductance, the henry, is named in his honor. Henry's work on the electromagnetic relay was the basis of the practical electrical telegraph, invented by Samuel F. B. Morse and Sir Charles Wheatstone separately. Condition: Reinforced fold & corners, light soil, otherwise very good with strong signatures.
