Rolf Hosemann

Rolf Hosemann (born April 20, 1912 in Rostock ; † September 28, 1994 in Berlin ) was a German physicist who laid the mathematical foundations for the theory of the paracrystal .

He studied at the University of Marburg and the University of Freiburg . In 1936 he received his doctorate in Freiburg. He had received the topic of his dissertation The radioactivity of the samarium from his academic teacher George de Hevesy , who had to leave Germany in 1934 because of his Jewish descent. In 1939 he completed his habilitation with a thesis on small-angle X-ray scattering on cellulose . In 1951 he became a research associate with Max von Laue at the Kaiser Wilhelm Institute for Physical Chemistry and Electrochemistry in Berlin , which later became the Fritz Haber Institute. In 1960 he was appointed head of his own department at the Fritz Haber Institute , and in 1966 the Max Planck Society appointed him a scientific member. He retired in 1980.

Around 1950 he founded the theory of the paracrystal .

The Chemistry Department of the Free University of Berlin awarded him an honorary doctorate on February 18, 1974 in recognition of his services to the development of theoretical crystallography, especially the theory of the paracrystals, and his fundamental work on the structure of macromolecules . Hosemann was married to Ursula (née Siebold), with whom he had four sons.
