[edit] Personal life
Born in Kristiania, his parents were gynaecologist Ernst Hassel (1848–1905) and Mathilde Klaveness (1860–1955).[1] Through his sister Ella, he was a brother-in-law of architect August Nielsen.[2] Hassel himself did not marry.[1]
[edit] Career
In 1915, he entered the University of Oslo where he studied mathematics, physics and chemistry, and graduated in 1920. After taking a year off from studying, he went to Munich, Germany to work in the laboratory of Professor Kasimir Fajans.[3] His work there led to the detection of absorption indicators. After moving to Berlin, he worked at the Kaiser Wilhelm Institute, where he began to research X-ray crystallography.[4] He furthered his research with a Rockefeller Fellowship, obtained with the help of Fritz Haber. In 1924, he obtained his PhD from the Berlin University, before moving to the University of Oslo, where he worked from 1925 through 1964, as a professor from 1934.[5]
Back in Oslo, Hassel originally focused on inorganic chemistry, but beginning in 1930 his work concentrated on problems connected with molecular structure, particularly the structure of cyclohexane and its derivatives. He introduced the Norwegian scientific community to the concepts of the electric dipole moments and electron diffraction. After publishing a paper on the conformations of cyclohexane,[citation needed] Hassel was arrested by the occupation authorities on 15 Octobe 1943. After a time in Bredtveit concentration camp until 22 November 1943, he was sent to Berg concentration camp, and on 9 December 1943 further to Grini concentration camp. He remained here until 6 November 1944.[6]
[edit] Nobel Prize
Beginning in 1950, Hassel investigated the structure of charge-transfer compounds, and was eventually able to set up rules for the geometry of this kind of compound. He was awarded the Nobel Prize for chemistry in 1969, alongside Derek Barton.
