Dorothy Crowfoot Hodgkin, and English Chemist, devoted her career to making the invisible visible. Her pioneering work in X-ray crystallography revealed the molecular structures of penicillin, vitamin B12, and after more than three decades of persistence: insulin. But the journey of Britain’s first female Nobel laureate in science began much earlier, with a simple gift that sparked a lifetime of curiosity.
It began with a spark in Sudan. At 15, during a family visit, a soil chemist gifted Dorothy a chemistry set. The teenage girl, thrilled, created a mini-lab and began experimenting with local plants. That early fascination bloomed into a passion, pushing her through Oxford’s then-unwelcoming gates for women in science. By her fourth year, she was elbow-deep in crystal structures, joining a tiny research group focused on the mysterious diffraction patterns X-rays made as they passed through molecules.
Crystallography in the 1930s was painstakingly manual—developing plates, calculating atom positions by hand. But Hodgkin believed in the method’s promise. Her quiet perseverance and bold intellect led to stunning successes: she mapped penicillin during WWII and vitamin B12 in 1956. These breakthroughs helped cement X-ray diffraction as a core tool in molecular biology. But Hodgkin had her sights on a bigger prize, insulin. She started the work in the 1930s, but the complexity of the molecule, with over 800 atoms, delayed its decoding for decades.
It wasn't until 1969, with the help of early computers, that Hodgkin’s vision crystallized. The structure of insulin, critical to diabetes treatment, was finally revealed, fulfilling her lifelong quest. Her unorthodox path, often outside academic norms and fueled by minimal funding, showed the world what unshakable scientific faith could achieve.
