Michael Faraday (1791-1867), a chemist and physicist at the Royal Institution of Great Britain, discovered electromagnetic induction at the same time as, but independently of, Joseph Henry, the first Secretary of the Smithsonian Institution. This portrait of Faraday is from the Smithsonian Institution Archives Web site “Henry’s Scientific Colleagues Gallery which features portraits of some of Henry’s most important colleagues, including Henry’s teacher, Amos Eaton, fellow scientist Alexander Dallas Bache, and protégé Alexander Graham Bell.
