In his book "The Double Helix," Watson provides his first-person account of the search for and discovery of DNA. He paints a sympathetic but sometimes critical portrait of Franklin. He praises her intellect and scientific acumen, but portrays her as difficult to work with and careless with her appearance. After introducing her in the book as "Rosalind", he writes that he and his male colleagues usually referred to her as "Rosy", the name people at King's College London used behind her back. She did not want to be called by that name because she had a great-aunt Rosy. In the family, she was called "Ros". To others, she was simply "Rosalind". She made it clear to an American visiting friend Dorothea Raacke, while sitting with her at Crick's table in The Eagle pub in Cambridge: Raacke asked her how she was to be called and she replied "I'm afraid it will have to be Rosalind", adding "Most definitely not "Rosy"."
