Professor Dorothy Crowfoot Hodgkin, winner of the 1964 Nobel Prize for Chemistry, is photographed in her laboratory at the Department of Chemical Crystallography at University of Oxford in Oxford, England, on Dec. 4, 1964. Hodgkin determined the three-dimensional structure of a complex bio-organic molecule by X-ray diffraction. She also determined the structure of penicillin and vitamin B12. Headlines at the time read "Oxford housewife wins Nobel" and "British woman wins Nobel Prize - £18,750 prize to mother of three." AP Photo
