Georg Simon Ohm was born in Erlangen, the son of a locksmith. He received home education, then studied at the University of Erlangen, but did not complete the course due to financial difficulties. He worked as a mathematics and physics teacher in various schools. In 1826 he published his main work, “Determination of the Law According to which Metals Conduct Contact Electricity,” in which he formulated Ohm's law. His discovery was not immediately recognized; it was only in 1841 that the Royal Society of London awarded him the Copley Medal. From 1849 he was a professor at the University of Munich.
