Happy birthday to x-ray #crystallographer Dorothy Mary Crowfoot Hodgkin (née Crowfoot, 1910-1994), Nobel laureate in #chemistry for her models of biomolecules like penicillin, vitamin B12 & insulin.

She was “captured for life by chemistry and crystals,” in childhood, 1 of 2 girls allowed to study chemistry rather than domestic science at her school with a small lab in her attic. On her 16th birthday her mother gave her 🧵1/

W.H. Bragg’s ‘Concerning the Nature of Things’ about x-ray crystallography, which used scatter pattern of x-rays through crystals at different angles to image & deduce their structure. She graduated Oxford in chemistry in ‘32.

During her PhD at Cambridge (‘37) she became interested in use of x-ray crystallography to study the structure of proteins & worked with Bernal on the 1st application of the method to image a biomolecule, pepsin. She returned to Oxford in ’34 to teach with her own lab. 🧵2

She missed the day Bernal made the 1st photo of an x-ray of a protein crystal for health reasons, diagnosed with chronic rheumatoid arthritis at only 24. She was appointed the college’s first fellow & chemistry tutor in ’36. During secret wartime work on penicillin she had to send her husband in Newcastle a telegram to alert him of the arrival of their 2nd of 3 kids. When publishing penicillin results in ’49 she bowed to social pressure & added Hodgkin to her name, though she previously 🧵3/

published as Dorothy Crowfoot.

Her 1954 published vitamin B12 study was described by Nobel Laureate Lawrence Bragg as “breaking the sound barrier.” She published the final structure in 1955 & 56.

One of her most important and celebrated studies was the longest lasting. From 1934-1969 she & team revealed the structure of insulin which contains 788 atoms! This work was instrumental in our ability to mass-produce insulin & create even better drug options.

Concerned about social inequities and preventing war in ’76 she became the longest-serving president of the international Pugwash Conference on Science and World Affairs, which brings scientists & public figures to work together to reduce the risk of armed conflict & seek solutions to global security threats. 5/5
