Hans Falkenhagen

Hans Eduard Wilhelm Falk Hagen ( born May 13, 1895 in Wernigerode, † June 26, 1971 in Rostock ) was a German physicist and co-founder of electrolyte theory.

Life

The son of a sculptor studied from 1913 physics, mathematics and chemistry at the Universities of Heidelberg, Munich and Göttingen. In 1921 he received his doctorate in the later Nobel laureate Peter Debye in Göttingen. He then worked for a year as an assistant at the Technical University of Gdansk. In 1922, he joined the University of Cologne, where he worked as an assistant to Karl Forester compact with optics and atomic physics. He habilitated in 1924 and then received at the Institute for Theoretical Physics an unscheduled teaching. After he had from 1927 to 1928 used a research grant to to work again with Debye at the Universities of Zurich and Leipzig, he was appointed in 1930 in Cologne, associate professor of theoretical physics. In 1933 he joined the Nazi Party.

In 1936 he followed a call to Dresden, where he was director of the Institute for Theoretical Physics at the Technical University until 1945. After a mean time as a freelance writer in Radebeul Falk Hagen took over in 1949 a full professorship at the University of Rostock in 1951 and founded the Institute for Theoretical Physics, whose director he remained even after his retirement in 1962 to 1964.

Performance

In addition to his teacher Peter Debye and Erich Hückel and Onsager Lars Falk Hans Hagen is one of the founders of the electrolytic theory, often referred to as the Debye- Hückel - Onsager theory called Falk Hagen ( an evolution of the Debye- Hückel theory). Together with his teacher Debye succeeded him first an interpretation of the dispersion of the conductivity of strong electrolytes. Subsequently, he developed a qualitative theory of the Wien effect and eventually a theory of the viscosity of strong electrolytes.

Falk Hagen has published numerous scientific papers, including the standard works electrolytes and theory of electrolytes.

Honors

Falk Hagen was a regular member of the German Academy of Sciences in Berlin, and since 1962 the German Academy of Sciences Leopoldina since 1955. In recognition of his services he was in 1955 with the National Prize of the GDR III. Class excellent.

On 24 March 2011 the City Council of Wernigerode, a street in the commercial district decided " on smatvelde " by Hans Falk Hagen named.
