Search engine major Google on Monday celebrated the birth anniversary of British chemist Dorothy Hodgkin with a doodle.
Born in 1919 in Egypt, Hodgkin was awarded the Nobel Prize in Chemistry for her discovery of the molecular structure of vitamin B12.
She advanced the technique of X-ray crystallography: a method used to determine the three-dimensional structures of bio-molecules. She used the technique to work out the structure of penicillin in 1946.
She won the Nobel Prize in Chemistry in 1964 “for her determinations by X-ray techniques of the structures of important biochemical substances”.
An image of the molecule, that is also represented in the doodle, is actually on display in the Science Museum in London.
She also won the Lenin Peace Prize, and was awarded the Order of Merit, only the second woman to do so, after Florence Nightingale.
She died in July 1994, aged 84.
