Thursday's Google Doodle celebrates the birthday of Rosalind Franklin, the first photographer of DNA.
Photographs document the stations of human life: the snapshot of a young child tossing a ball, the image of a young bride coming down the aisle, the portrait of an old man lined with age and wrinkles.
But when Rosalind Franklin took an x-ray diffraction image of DNA in 1952, the scientist had captured more than a second of humanity. She created an image of the building block of humans. This photo of DNA was referred to as Photo 51. In her lifetime, Ms. Franklin received only token recognition of her contributions to the study of DNA, while James Watson and Francis Crick were widely hailed as the scientists that discovered the molecule's double-helix structure.
Thursday’s Google Doodle celebrates what would have been Rosalind Franklin’s 93rd birthday with an image of Mr. Watson and Mr. Crick’s double helix – and Franklin’s Photo 51.
