Karl Ernst Zsigmondy (born March 27, 1867 in Vienna ; † October 14, 1925 there ) was an Austrian mathematician and university professor . He was rector of the Vienna University of Technology .

Life

Karl Zsigmondy first visited the school in Hernals , from 1886 studied at the University of Vienna mathematics, where he in 1890 with a dissertation about the properties of Binominalreihe and some impact the same to Dr. phil. PhD. His teachers included Gustav von Escherich , Emil Weyr and Josef Stefan . After completing his doctorate, he went to the University of Berlin in 1891 to study number theory with Leopold Kronecker . After Kronecker's death, he moved to Felix Klein at the University of Göttingen , and later to the Sorbonne in Paris . In 1893 he returned to Vienna, and the following year he qualified as a professor for mathematics at the University of Vienna.

From 1895 to 1901 he was an assistant to Emanuel Czuber at the chair for mathematics at the Vienna University of Technology, from 1902 he was an associate professor there. In 1905 he was appointed full professor of mathematics at the German Technical University in Prague . After Moritz Allé retired in 1906, he returned to Vienna, where he was chairman of the chair for mathematics I (until 1921) and II (from 1921) until his death in 1925. Hermann Rothe was one of his assistants . In the academic years 1916/17 and 1917/18 as well as 1920/21 he was dean of the general department, in the academic year 1918/19 he was elected rector of the Vienna University of Technology .

In 1921 he was appointed councilor . A number theory theorem was named after him.

His brother Richard Zsigmondy received the Nobel Prize in Chemistry in 1925, while his brothers Emil and Otto were mountaineers and physicians. Their common father was the dentist Adolph Zsigmondy .

Karl Zsigmondy died in 1925 at the age of 58 and was buried at the Evangelical Cemetery in Simmering .
