April 25 is #NationalDNADay so I’m sharing my portrait of Rosalind Franklin (1920 – 1958), #chemist & x-ray #crystallographer whose x-ray diffraction images were instrumental to discovering double-helix structure of #DNA, made important contributions to #carbon & #virus research, was 1 of the great scientists of the 20th century.
There’s a joke amongst scientists that goes, “What did Watson & Crick discover?”
