Though remembered best for formulating an electrical principle known as Ohm's Law (wherein Current through a conductor equals Voltage divided by Resistance), this nineteenth-century scientist also developed both Ohm's Phase Law and Ohm's Acoustic Law.
After earning an advanced mathematics degree from the University of Erlangen, he taught mathematics and physics and also developed a geometry textbook.
He was an 1841 recipient of the prestigious Copley Medal.
He was born in Erlangen, Brandenburg-Bayreuth, to Maria Elizabeth Beck and Johann Wolfgang Ohm. One of his siblings, Martin Ohm, became a famous mathematician.
His formulation of Ohm's Law would not have been possible without Alessandro Volta's invention of the electrochemical cell.
