She is credited with writing the first book discussing both differential and integral calculus and was an honorary member of the faculty at the University of Bologna.
She devoted the last four decades of her life to studying theology (especially patristics) and to charitable work and serving the poor. This extended to helping the sick by allowing them entrance in to her home where she set up a hospital.

Dorothy Hodgkin's 104th Birthday



Dorothy Mary HodgkinOM, FRS (12 May 1910 – 29 July 1994), née Crowfoot, was a British biochemist, 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 and Edward Abraham had previously surmised, and then the structure of vitamin B, for which she was awarded the Nobel Prize in Chemistry. She was the third woman to win the prestigious Nobel Prize in Chemistry.
In 1969, after 35 years of work and five years after winning the Nobel Prize, Hodgkin was able to decipher the structure of insulin. X-ray crystallography became a widely used tool and was critical in later determining the structures of many biological molecules where knowledge of structure is critical to an understanding of function. She is regarded as one of the pioneer scientists in the field of X-ray crystallography studies of biomolecules. Hodgkin published as Dorothy Crowfoot until 1949, when she was persuaded by Hans Clarke’s secretary to use her married name on her chapter in The Chemistry of Penicillin. Thereafter she always published as Dorothy Crowfoot Hodgkin.
