Stefan Rozental (born August 13, 1903 in Łódź , now Poland, † August 2, 1994 in Copenhagen ) was a nuclear physicist and long-time assistant to Niels Bohr . In 1934 he had the name Rozenthal, which he changed to Rozental between 1941 and 1963.

Life

Rozental was with his family in Denmark during the First World War , where he attended school. In 1919 he returned to Poland. He received his doctorate in Kraków in 1928 and was - with interruptions - as a postdoc with Werner Heisenberg in Leipzig from 1929 to 1934 . From 1934 to 1938 Rozental was a lecturer in Krakow. In 1938 he left Poland and went to Niels Bohr in Copenhagen. After Hendrik Anthony Kramers (from 1916) and Léon Rosenfeld (from 1934) he was Niels Bohr's assistant for over fifteen years . Rozental accompanied Bohr on many trips and acted as his "right hand man". Like Bohr, he fled the German persecution of the Jews from Denmark in September 1943 and like Bohr returned to Copenhagen after the end of the Second World War , which he experienced in Sweden. From 1952 to 1957 he was a member of the CERN theory group - before the decision to locate CERN in Geneva, it was in Copenhagen - and managed its business, while Niels Bohr was the formal director. From 1957 to 1972 he was Associate Professor at NORDITA, which was founded as the theory institute of the Scandinavian countries to secure the future of the Niels Bohr Institute. From 1966 to 1972 he was Vice President of the IUPAP Executive Committee.

Rozental had been married to the German historian Hanna Kobylinski since 1949 , who had emigrated from Germany in 1933 and who fled with him to Sweden in 1943.
