Born in Cairo, Dorothy was a prominent British chemist. She advanced X-ray crystallography, protein crystallography, and confirmed the structures of cholesterol (1937), penicillin (1945) and vitamin B-12 (1954). In 1964, she was awarded the Nobel Prize for the latter of these accomplishments. Five years later, she discovered the structure of insulin. No doubt, this woman has touched the lives of thousands through the breakthroughs she made in chemistry.
A woman of indomitable spirit, she refused to let even severe arthritis call a halt to her scientific activity. Only last year, although wheelchair-bound, she flew to an international crystallography conference in Peking, to the astonishment of the other delegates who attended it.
