Watson is a U.S. molecular biologist, geneticist and zoologist, best known as one of the co-discoverers of the structure of DNA in 1953 with Francis Crick. In 1998, the Modern Library placed The Double Helix at number 7 on its list of the 100 best nonfiction books of the 20th century.
Franklin is best known for her work on the X-ray diffraction images of DNA while at King's College, London, which led to the discovery of the DNA double helix.ccording to Francis Crick, her data were key in determining Watson and Crick's 1953 model, the correct description of the helical structure of DNA. Watson also confirmed this opinion in his own statement at the opening of the King's College London FranklinâWilkins building in 2000.
