Ernst Gottfried Fischer
Ernst Gottfried Fischer (born July 17, 1754 in Hoheneiche near Saalfeld , † January 27, 1831 in Berlin ) was a German chemist, mathematician and physicist. He was a professor at the University of Berlin .
Life
Fischer was the son of a pastor and studied theology and mathematics with Johann Andreas von Segner in Halle from 1773 to 1776 . From 1782 to 1829 he taught mathematics and physics at the grammar school at the Gray Monastery in Berlin. He was also an associate professor of physics at the University of Berlin from 1810 to 1830. In the 1780s he taught the Humboldt brothers as a private teacher and from 1810 to 1816 the Prussian Crown Prince Friedrich Wilhelm in mathematics and natural sciences.
Fischer presented by Jeremias Benjamin Richter given equivalent weights of the stoichiometry of the uniform basis of sulfuric acid and made it so only known. They were taken over by Claude Louis Berthollet in 1803 in his book Essai de statique chimique .
In 1801 he translated the Recherches sur les lois de l'affinité by Claude-Louis Berthollet into German (1802) and referred to Richter's system in a note. In 1783 he discovered the abnormal regular astigmatism of the eye.
He also developed a mathematical theory of dimensional signs. His main merit is in the educational field. He wrote textbooks in mathematics and physics and designed curricula for secondary schools (1805).
He had been a member of the Berlin Academy since 1803 . Since 1819 he was a member of the Leopoldina . In 1801 he was in the Masonic lodge Zur Eintracht in the Freemasons added.
