Georg (e) Friedrich Bärmann , also Latinized as Baermann , born as Behrmann , (born October 12, 1717 in Leipzig , † February 6, 1769 in Wittenberg ) was a German mathematician .

Life

Georg Friedrich Bärmann is the eldest son of the doctorate royal-Polish and electoral-Saxon high court and consistory advocate Georg Adam Behrmann in Leipzig († November 30, 1741) and his wife Christiana Sophia born. Paul. He had three younger brothers. At the time of the father's death, his two eldest sons had already chosen the spelling “Bärmann” for the family name (Latinized form: Baermann ), while the birth name of Behrmann is still recorded for the two younger brothers in the years 1725 and 1732 in Leipzig's baptismal registers.

After attending grammar school in Schulpforta , he studied in Leipzig from 1730 , including with Johann August Ernesti , mathematics and theology, and on November 29, 1732 earned the lowest academic degree of a baccalaureate . During his studies he switched to the University of Marburg , where he heard lectures from Christian Wolff . On February 17, 1735, when he returned to Leipzig, he acquired the degree of Master of Philosophy.

In 1745 he took over the chair of Johann Matthias Hase in lower mathematics in Wittenberg . As a member of the German Society in Leipzig, he promoted the same endeavors at the Leucorea and wrote a “Brief Guide to German Language Art” himself, which was published in 1776 from his estate. In 1755 he succeeded Johann Friedrich Weidler in the higher mathematics professorship. One would have liked to see him combine both professorships, but the state government refused.

Bärmann's merit lies particularly in the field of algebra. It was from him that the first general proof of the formulas for the power sums of the roots of equations established by Isaac Newton comes .
