Life

Karl Exner was the second son of Franz Serafin Exner and his wife Charlotte Dusensy. He had four siblings: Adolf , Sigmund , Marie and Franz-Serafin . After attending the Schottengymnasium in Vienna, Zurich and Freiburg, he studied mathematics and physics, passed the teaching examination for these subjects in 1865, and received the diploma of a Dr. phil. of the University of Freiburg i.Br. and initially worked as a supplement (assistant teacher) in Mödling , Troppau and Vienna from 1871 to 1874 . He was married to Henriette Wagner (* 1863). For a while he attended lectures at the Swiss Federal Polytechnic in Zurich . In 1892 he completed his habilitation as a private lecturer in theoretical physics at the University of Vienna. In 1894 he followed a call to the professorship for mathematical physics in Innsbruck, which he held until 1912.

meaning

Among other things, he dealt with the wave theory of light and geometric problems and was distinguished by innovative ideas and experimental skills. In this way he succeeded in interpreting Newton's color rings theoretically; he was concerned with meteorological optics and the twinkling of stars . In 1890 he received the very prestigious Baumgartner Prize of the Vienna Academy, which was later received primarily by important scientists from abroad such as Lenard, Röntgen and Einstein, and a prize from the Chemical and Physical Society in Vienna.

A serious illness forced Exner to retire in 1904.
