Rosalind Franklin was a British pioneer in science in the early 1950s, yet her groundbreaking role in the discovery of DNA’s double helix structure is still often overlooked. Based on a true story, Photograph 51 presents an intriguing portrait of a complex, courageous woman making her way in a male-dominated field. While rival teams of researchers compete for a breakthrough, Rosalind, focused and unbending, is locked in a race of her own. A hit in the West End, it was proclaimed “A triumph” by The Telegraph.
