<em>Joseph Henry (1797-1878) was Professor of Natural Philosophy at Princeton.
His interests focused on electromagnetism. A contemporary of Michael Faraday,
he discovered self-induction in current-carrying coils. The unit of induction
— the Henry — is named in his honor. He pioneered the creation of high
magnetic fields, electric motors, and the telegraph. He became Secretary of
