Hans Falkenhagen

from Wikipedia, the free encyclopedia

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

Life

The son of a sculptor or builder had three siblings. After a childhood audition on the violin in Wernigerode Castle , the family was proposed to send Hans Falkenhagen to study at the music academy in Berlin, but from 1913 he studied physics, mathematics and chemistry at the universities of Heidelberg , Munich and Göttingen . In 1921 he received his doctorate from the later Nobel Prize winner Peter Debye in Göttingen. He then worked for a year as an assistant at the Technical University of Gdansk . In 1922 he moved to the University of Cologne , where he joined as an assistant Karl Forester compact with optics and atomic physics employed. He completed his habilitation in 1924 and then received an unscheduled teaching position at the Institute for Theoretical Physics. After he had used a research grant from 1927 to 1928 to work again with Debye at the universities in Zurich and Leipzig , he was appointed associate professor for theoretical physics in Cologne in 1930. In 1933 he joined the NSDAP .

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 period as a freelance writer in Radebeul , Falkenhagen took over a full professorship at the University of Rostock in 1949 and founded the Institute for Theoretical Physics there in 1951, of which he remained director until 1964 after his retirement in 1962. Günter Kelbg and Werner Ebeling are among his students .

power

In addition to his teacher Peter Debye and Erich Hückel and Lars Onsager, Hans Falkenhagen is one of the founders of the electrolyte theory , often referred to as the Debye-Hückel-Onsager-Falkenhagen theory (a further development of the Debye-Hückel theory ). Together with his teacher Debye, he first succeeded in interpreting the dispersion of the conductivity of strong electrolytes. He then developed a qualitative theory of the Wien effect and finally a theory of the viscosity of strong electrolytes.

Falkenhagen published numerous scientific papers, including the standard works Electrolytes and Theory of Electrolytes .

Honors

Falkenhagen had been a full member of the German Academy of Sciences in Berlin since 1955 and of the German Academy of Sciences Leopoldina since 1962 . In recognition of his services he was awarded the National Prize of the GDR III in 1955 . Class excellent.

On March 24, 2011, the city council of Wernigerode decided to name a street in the Schmatzfelder Chaussee industrial park after Hans Falkenhagen.

family

Hans Falkenhagen had two sons and a daughter with his wife Annemarie (1906–1988). The youngest son, Dieter Falkenhagen , studied physics and medicine and became a kidney specialist. He became head of the department for artificial organs at the Clinic for Internal Medicine at the University of Rostock; later he worked at Fresenius and then built up an institute for biomedical technology, which was affiliated to the Danube University in Krems an der Donau . Dieter Falkenhagen's wife Ursula Falkenhagen was appointed professor in Rostock in 1993.
