Michael Faraday ( 1791 – 1867) was a British scientist who contributed to the study of electromagnetism and electrochemistry. His main discoveries include the principles underlying electromagnetic induction, diamagnetism and electrolysis. He was arguably the best experimentalist in the history of science. In 1824, he became a member of the Royal Society. In 1833, he was appointed to the Fullerian Professorship of Chemistry, a position he held until the end of his life.
