Dorothy Hodgkin

Dorothy Mary Crowfoot Hodgkin (May 12, 1910 – July 29, 1994) was a British chemist who became the only British woman to have won a Nobel Prize in her own right and one of only four women to have won the Nobel Prize in Chemistry. Born in Cairo, Egypt, to a British family, Hodgkin developed an early fascination with chemistry and crystallography while studying at Oxford University. She pioneered the use of X-ray crystallography to determine the three-dimensional structures of important biological molecules, a revolutionary approach that fundamentally advanced biochemistry and medicine. Her most famous achievement was determining the structure of vitamin B12 in 1956, an extraordinarily complex molecule whose structure had eluded scientists for years. She received the Nobel Prize in Chemistry in 1964 for this achievement and her other groundbreaking structural determinations. Beyond her scientific contributions, Hodgkin was also a passionate peace activist and advocate for international scientific cooperation during the Cold War, serving as president of the Pugwash Conferences on Science and World Affairs. Her work laid the foundation for modern structural biology and drug design, influencing countless subsequent scientific advances. Hodgkin remained active in research and activism until her death, embodying both scientific excellence and moral commitment.
