Ludwig Kiepert
Friedrich Wilhelm August Ludwig Kiepert (born October 6, 1846 in Breslau , Lower Silesia , † September 5, 1934 in Hanover , Lower Saxony ) was a German mathematician and university professor .
Life
His father Ludwig Kiepert (1811–1847) was a Protestant pastor in Breslau. He died a year after the birth of his son Ludwig, who grew up without any siblings. His mother was Wilhelmine Friederike Müller (1814–1886), a pastor's daughter. Ludwig attended the Maria-Magdalenen-Gymnasium in Breslau from 1856 , which he left with the Abitur in 1865. In the same year he began studying mathematics at the University of Wroclaw . After moving to Berlin's Humboldt University , it was mainly Karl Weierstrass who had a strong influence on him and from whom Kiepert obtained his doctorate in 1870 . At the age of 29 he married Anna Betz , with whom he had two children. His house, built in 1898 on the Herrenhäuser Kirchweg / corner of Rühlmannstrasse, was the first of numerous professors who later also built in the area.
On the mediation of Weierstrass, Kiepert received a private lectureship at the University of Freiburg in 1871 . A year later he became an associate professor here. In 1877 Kiepert went to the Technical University of Darmstadt as a full professor of mathematics for two years . In 1879 he moved to the Technical University of Hanover as a full professor of higher mathematics , where he also took over the post of rector from 1901 to 1904 .
In 1890 Ludwig Kiepert was one of the founding members of the German Mathematicians Association (DMV) together with Rudolf Sturm . From 1893 Kiepert was also the mathematical director of the Prussian civil servants' association . He has made a particularly good contribution in the field of insurance. It is thanks to him that mathematics has become a defining element of insurance.
With his college friend Felix Klein , he founded the first institute in Germany in 1895 at the Georg-August University in Göttingen , where all areas of insurance were taught: actuarial mathematics , insurance law and insurance management . In addition to a large number of specialist publications, Kiepert also wrote numerous textbooks on differential calculus and integral calculus , which were used at universities for decades. He stayed in Hanover until his retirement (1921), but continued to work in science. Associated with his name are terms such as the "Kiepertian parabola" or the Kiepertian hyperbola , which he had already discovered while studying in Berlin.
Kiepert retired on April 1, 1921 , but held a few lectures thereafter. He died in 1934 at the age of 88.
A portrait of Kiepert in oil is in the Hanover University Archives.
family
In 1875 he married Anna Betz (1857–1941), the daughter of Colonel Ludwig Emil Betz (1828–1895). The couple had a son and a daughter. The son Max (1879–1963) became the district president and ministerial councilor.
