Photograph 51 is a play by Anna Ziegler. Photograph 51 opened in the West End of London in September 2015. The play focuses on the often-overlooked role of X-ray crystallographer Rosalind Franklin in the discovery of the double helix structure of DNA while working at King's College London. This play won the third STAGE International Script Competition in 2008. The title comes from Photo 51, the nickname given to an X-ray diffraction image taken by Raymond Gosling in May, 1952, under the supervision of Rosalind Franklin. The one-act play runs for 95-minutes with no intermission.
