Born in [[Kristiania]] ([[Oslo]]), his parents were Ernst Hassel, a [[gynaecology|gynaecologist]], and Mathilde. ==Biography== 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]].<ref>''[http://books.google.com/books?id=BJbJw2TQVqwC&pg=PA65&lpg=PA65&dq=%22odd+hassel%22+%22kasimir+fajans%22&source=web&ots=RiuQVI8tE6&sig=XpzlMw4yFpi_3xvYEJXowNvL5yw&hl=en Candid Science III: More Conversations with Famous Chemists]'', Istvan Hargittai, Magdolna Hargittai, Imperial College Press, 2003.</ref> His work there lead to the detection of [[absorption]] indicators. After moving to [[Berlin]], he worked at the [[Kaiser Wilhelm Institute]], where he began to reasearch [[X-ray crystallography]].<ref>[http://www.bookrags.com/biography/odd-hassel-wsd/ Odd Hassel biography] bookrags.com</ref> 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.<ref>[http://nobelprize.org/nobel_prizes/chemistry/laureates/1969/hassel-bio.html Odd Hassel - The Novel Prize in Chemistry 1969], nobelprize.org</ref> ==Career== Back in Oslo, Hassel originally focussed 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 moment]]s and [[electron diffraction]]. After publishing a paper on the conformations of cyclohexane, Hassel was arrested by Norwegian [[Nazis]] and sent to the [[Grini]] [[concentration camp]] until 1944. ==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]]. ==References== {{reflist}} ==External links== * Hassel's [http://nobelprize.org/nobel_prizes/chemistry/laureates/1969/hassel-bio.html Nobel Foundation biography] * Hassel's Nobel Lecture [http://nobelprize.org/nobel_prizes/chemistry/laureates/1969/hassel-lecture.pdf Structural Aspects of Interatomic Charge-Transfer Bonding] {{Nobel Prize in Chemistry Laureates 1951-1975}} {{Lifetime|1897|1981|Hassel, Odd}} [[Category:Physical chemists]] [[Category:Nobel laureates in Chemistry]] [[Category:People from Oslo]] [[Category:Nazi concentration camp survivors]] [[ar:أود هاسل]] [[ca:Odd Hassel]] [[da:Odd Hassel]] [[de:Odd Hassel]] [[es:Odd Hassel]] [[fr:Odd Hassel]] [[id:Odd Hassel]] [[it:Odd Hassel]] [[sw:Odd Hassel]] [[nl:Odd Hassel]] [[ja:オッド・ハッセル]] [[no:Odd Hassel]] [[pl:Odd Hassel]] [[pt:Odd Hassel]] [[ro:Odd Hassel]] [[ru:Хассель, Одд]] [[fi:Odd Hassel]] [[sv:Odd Hassel]] [[zh:奥德·哈塞尔]]
