Dorothy Hodgkin was a British scientist born in Cairo. She had serious health problems but she worked continuously despite them. In 1928, she started to study chemistry in Oxford and 20 years later, in 1948, she discovered the structure of vitamin B-12 and later, she presented the structure of penicillin. She won the Nobel Prize in Chemistry for these discoveries. She worked for decades on insulin and finally she discovered its structure. It was a very important discovery for the development of medicine, which helped people with diabetes. Dorothy Hodgkin urodziła się w Kairze, ale studiowała w Oxfordzie.     1.
