Johann Salomo Christoph Schweigger (born April 8, 1779 in Erlangen , † September 6, 1857 in Halle an der Saale ) was a German physicist and chemist .

Life

JSCSchweigger is the son of Friedrich Christian Lorenz Schweigger, associate professor of theology in Erlangen from 1786 until his death in 1802. He first studied philosophy in Erlangen . His dissertation dealt with the Homeric question that was raised by Friedrich August Wolf . With this he also qualified as a private lecturer , but then let Johann Tobias Mayer , Georg Friedrich Hildebrandt (1764-1816) and Karl Christian Landsdorff change his mind to switch to the natural sciences and held lectures as a private lecturer in Erlangen for three years, until 1803 from these areas

In October 1803 he was employed as a professor at the grammar school in Bayreuth and in 1811 at the polytechnic school in Nuremberg . 1816-1819 Schweigger was a full professor of philosophy and taught physics and chemistry in Erlangen.

In 1816 he was elected a member of the Leopoldina .

In 1819 he went to the University of Halle . In Bayreuth he became a member of the Masonic Lodge Zur Sonne .

Schweigger's physical work relates to electrical issues. As early as 1808 he had constructed electrometers to measure the electrical force through the magnetic. Immediately after Oersted's discovery, in 1820, Schweigger invented the electromagnetic multiplier that bears his name ( Schweigger multiplier ). This was a wire-wound galvanic current meter, also called a galvanometer . It had a magnetic needle like Oersted's, which was wrapped with wire several times. The needle was deflected by the magnetic effect of the electric current and thus indicated its strength.

In 1811 he took over the publication of the journal for chemistry and physics from Adolf Gehlen (1775-1815). As a continuation of this journal, he founded the Yearbook for Chemistry and Physics , which he later left to the adoptive son of his brother August Friedrich Schweigger , the professor of medicine Franz Wilhelm Schweigger-Seidel .

He is the father of Karl Ernst Theodor Schweigger and doctoral supervisor of Wilhelm Eduard Weber . Johann Salomo Christoph Schweigger died on September 6, 1857 in Halle an der Saale.
