Georg Simon Ohm, (March 16, 1789 - July 6, 1854) a German physicist, was born in Erlangen and educated at the university there. His most important finding was Ohm's Law, which he first published in his pamphlet Die galvanische Kette mathematisch bearbeitet, in 1827. This work, the germ of which had appeared during the two preceding years in the journals of Schweigger and Poggendorff, has exerted an important influence on the development of the theory and applications of electric current. Ohm's name was adopted as the SI unit of resistance, the ohm (symbol Ω).
