Rosalind Franklin - Credit: By MRC Laboratory of Molecular Biology - From the personal collection of Jenifer Glynn A sculpted portrait of pioneering scientist Rosalind Franklin is to be unveiled in Hampstead. The biophysicist's X-ray Photo 51 helped Watson and Crick discover the double helix structure of DNA – but she didn't share their 1962 Nobel Prize because she died of ovarian cancer four years earlier. To mark International Women's Month, the property firm redeveloping the former Westfield College site in Kidderpore Avenue into luxury apartments, will install a tondo sculpture of Franklin framed by DNA formations. Franklin took the photograph in May 1952 while working as a research fellow at King's College London, before going on to work on the molecular structure of viruses at Birkbeck. When King's later took over the Westfield site, it named a student building after her.
