Dorothy Hodgkin

Biography

Dorothy Mary Crowfoot Hodgkin, born on 12 May 1910 in Cairo, Egypt, was a British chemist and crystallographer. Her groundbreaking use of X-ray crystallography opened up new understanding of complex biological molecules. She is considered one of the leading scientists of the twentieth century and remains the only British woman to have won the Nobel Prize in Chemistry, which she received in 1964 for determining the structures of key biochemical substances. Her work spanned chemistry, physics, and biology, laying the foundation for modern structural biology and drug development.

Hodgkin studied at Somerville College, Oxford, and completed her doctoral research at Newnham College, Cambridge, before returning to Oxford, where she spent most of her academic career. Early on, she focused on using X-ray diffraction to uncover atomic arrangements within crystallized molecules. This work required great patience and mathematical skill, and Hodgkin continually advanced the technique, especially as computational tools became available for analyzing diffraction data.

One of her most notable achievements was determining the structure of penicillin in the 1940s, which confirmed a proposed molecular arrangement. This work was crucial for synthesizing and improving antibiotics during and after World War II. Her determination of the structure of vitamin B12 in 1955 was considered a monumental scientific accomplishment due to its complexity. The Nobel Committee specifically cited this work when she won the prize in 1964, making her the third woman ever to win the Nobel Prize in Chemistry. She later solved the structure of insulin in 1969, completing a project she started in the 1930s.

Hodgkin married historian Thomas Lionel Hodgkin in 1937 and initially continued using the name Dorothy Crowfoot professionally before adopting Dorothy Crowfoot Hodgkin. Besides her scientific contributions, she was known for her humanitarian efforts, including her strong support for international scientific cooperation during the Cold War and her advocacy for peace. She received the Lenin Peace Prize and several notable scientific honors, including the Royal Medal in 1956, the Copley Medal in 1976, the Lomonosov Gold Medal in 1986, and the Order of Merit in 1965. She was elected a Fellow of the Royal Society in 1947, one of the first women to achieve this.

Dorothy Hodgkin died on 29 July 1994 in Ilmington, Warwickshire. Her impact on science lives on through the structural data she gathered, the methods she improved, and the institutions and fellowships named after her.
