Arnold Eucken (3 July 1884 – 16 June 1950) was a German chemist and physicist.


Eucken was born as a son of the philosopher and later Nobel Prize winner Rudolf Eucken in Jena. He completed his study in Kiel, Jena and Berlin. There he worked as a coworker of Walther Nernst, getting his PhD in 1906 and habilitated in 1911 [1]. Starting from 1915 Eucken held a chair at the Technische Hochschule Breslau, starting from 1930 at the University of Göttingen as a successor of Gustav Tammann. After "the seizure of power" of the National Socialists, Eucken became a member of the NSDAP in 1933 and worked further as a full professor in Göttingen.


Eucken made important contributions within physical and technical chemistry. He concentrated on specific heat at very low temperatures, the structure of liquids and electrolytic solutions, the molecular physics (rotation, oscillation), on deuterium and heavy water, on homogeneous and heterogeneous gas kinetics, catalysis, chemical engineering and chemical technology.


Eucken killed himself in Seebruck on 16 June 1950.[2]
