Arthur Korn

Arthur Korn (born May 20, 1870 in Breslau , † December 21, 1945 in Jersey City , New Jersey) was a German physicist and mathematician.

Life

Korn studied mathematics and physics in Freiburg from 1886 and later in Leipzig , where he received his doctorate in 1890 under Eilhard Wiedemann and Carl Gottfried Neumann ( on the applicability of combinatorial methods to reduce problems in hydrodynamics, electrodynamics and magnetic induction ). He then continued to study in Berlin , Paris , London and Würzburg . In 1895 he completed his habilitation at the University of Munich ( on the movement of continuous mass systems ), where he became a private lecturer and in 1903 an associate professor. In 1914 he finally took over the chair for physics at the TU Berlin .

In 1928 he was visiting professor at the University of Madrid .

As a scientist, he dealt with elasticity theory, potential theory, theoretical mechanics, integral equations, the telegraph equation and other problems in electrical engineering and quantum mechanics.

Korn became known for his attempts at picture telegraphy . A first "reasonably acceptable" (Korn) transmission of an image over a telephone line (Munich-Nuremberg-Munich) was possible as early as 1904. He used a selenium cell as a scanning instrument and a Nernst lamp as a light source. On October 17, 1906, he was able to send a portrait by telegraph over 1,800 kilometers. At the Natural Scientists Congress in Vienna in 1913, Korn showed the first successful telegraphic transmission of a cinematographic recording.

In 1923 he succeeded in transmitting a picture of Pope Pius XI in a media-effective manner. across the Atlantic. From 1928 his system was introduced to the German police .

Since Korn was of Jewish descent, he was dismissed from his position by the National Socialists in 1933 , but did not emigrate with his family to the USA via Mexico until 1939 . There he got a chair in physics and mathematics at the Stevens Institute of Technology in Hoboken , New Jersey .

In 1907 he was elected a member of the Leopoldina , in 1930 he was awarded an honorary doctorate from the Technical University in Breslau.
