Ohm, Georg Simon (1789–1854)

Born: Erlangen, Germany
Ohm is best known for his discovery of what we now call Ohm’s Law. Ohm held a variety of teaching posts at secondary schools as well as universities. In 1827 he published his greatest work, Die Galvanische Kette. Along with Andre Ampere, Ohmwas the first to publish rigorously mathematical and theoretical work on electricity. Ohm’s famous law states that current in a resistor is  proportional to the applied voltage and inversely proportional to the resistance. Ohm’s work was initially scorned because it lacked the experimental evidence.  Worldwide acclaim changed Ohm’s fortunes several years later.
He is honored by having his name used asthe unit of resistance, the ohm, and the unit of conductivity, the mho.
