'''Odd Hassel''' ([[May 17]] [[1897]] — [[May 11]] <!--sometimes given as 1991--> [[1981]]) was a [[Norway|Norwegian]] [[physical chemistry|physical chemist]] and [[Nobel Laureate]]. 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]].
