today is the birthday of 'Dorothy Hodgkin', who born on 12 May 1910, and died on 29 July 1994.

was a British chemist, credited with the development of protein crystallography. 
She advanced the technique of X-ray crystallography, a method used to determine the three dimensional structures of biomolecules. Among her most influential discoveries are the confirmation of the structure of penicillin that Ernst Boris Chain had previously surmised, and then the structure of vitamin B12, for which she was awarded the Nobel Prize in Chemistry.
