Their story
Why Dorothy Crowfoot Hodgkin matters
Hodgkin determined the structures of important molecules including penicillin, vitamin B12 and insulin.
Dorothy Crowfoot Hodgkin worked in Britain during the Modern era. Science was becoming a team effort carried out in universities, hospitals, observatories, industry and large research laboratories.
Studying chemistry means tracking changes that may be too small to see directly. Dorothy Crowfoot Hodgkin helped replace guesswork with observations, comparisons and explanations that other researchers could test.
Key discovery or invention
Using X-ray crystallography to solve molecular structures.
Dorothy Crowfoot Hodgkin's central contribution was using X-ray crystallography to solve molecular structures.
The work identified a pattern in matter or a reliable way to investigate chemical change. Careful measurement meant that the result could be reproduced instead of depending on appearance or tradition alone.
Why it still matters: Modern laboratories build on this approach whenever they identify substances, measure reactions or design new materials and medicines. Dorothy Crowfoot Hodgkin's work is one chapter in that continuing story rather than the final word.
She worked for decades on insulin before its detailed structure was finally solved.
