joseph henry in Science
Henry, Joseph 1797-1878.  
American physicist who studied electromagnetic phenomena. He discovered electrical induction independently of Michael Faraday, and constructed a small electromagnetic motor in 1829. He also developed a system of weather forecasting based on meteorological observations. The henry unit of inductance is named for him.
A SI derived unit of electrical inductance, especially of transformers and inductance coils. A current changing at the rate of one ampere per second in a circuit with an inductance of one henry induces an electromotive force of one volt.
