Birth of Georg Simon Ohm

16 March 1789

Georg Simon Ohm was born on 16 March 1789 in Erlangen. A German physicist and mathematician, Ohm discovered the law that bears his name, which states that the current through a conductor is proportional to the voltage across it. He published the result in 1827 in a mathematical treatment of electric circuits, but it was at first poorly received by his contemporaries, and he resigned from a teaching post in Cologne. His work was later recognized by the Royal Society in London, which awarded him the Copley Medal in 1841. He became a professor in Munich, and the unit of electrical resistance, the ohm, is named in his honor.
