1945 – Electron Density Map and Molecular Model of Penicillin

Electron density map and model of Penicillin created by Dorothy Crowfoot Hodgkin in 1945 based on her work on X-ray crystallography. The Penicillin molecule was the first molecule whose structure was derived entirely from X-ray data. Dorothy Hodgkin later received the Nobel price for applying the same technique to determine the structure of the B12 molecule. Dorothy Hodgkin (1910-94) was awarded the prestigious and exclusive Order of Merit in 1965 to add to her 1964 Nobel Prize for ”her […]



1947 – Dorothy Hodgkin's Electron Density Contours

Nobel prize winning crystallographer Dorothy Crowfoot Hodgkin created another physical visualization in the mid 1940's, showing part of the structure of penicillin. An original of this artifact is in the Oxford Museum of the History of Science. This technique recently inspired artist Angela Palmer for her glass portraits.
