Johann Salamo Christoph Schweigger

Died 6 Sep 1857 at age 78 (born 8 Apr 1779).German physicist who invented the galvanometer (1820), a device to measure the strength of an electric current. He developed the principle from Oersted's experiment (1819) which showed that current in a wire will deflect a compass needle. Schweigger realized that suggested a basic measuring instrument, since a stronger current would produce a larger deflection, and he increased the effect by winding the wire many times in a coil around the magnetic needle. He named this instrument a “galvanometer”in honour of Luigi Galvani, the professor who gave Volta the idea for the first battery. Thomas Seebeck (1770-1831) named the innovative coil, Schweigger's multiplier. It became the basis of moving coil instruments and loudspeakers.
