French physicist Ampere: Andr Ampre was a Professor at the cole Polytechnique from 1814 to 1828 and then at Universit de France from 1826 until his death. He worked on electromagnetism and analysis. He also made contributions to line geometry extending ideas of Binet. Ampre attempted to give a combined theory of electricity and magnetism in the early 1820's. He formulated a circuit force law and treated magnetism by postulating small closed circuits inside themagnetised substance. This approach became fundamental for the 19th Century.click to open
