on 12 March, and allegedly informed Gosling on his return to King's. It is uncertain how long it took for Gosling to inform Franklin at Birkbeck, but her original 17 March B-DNA manuscript does not reflect any knowledge of the Cambridge model. Franklin did modify this draft later before publishing it as the third in the trio of 25 April 1953 Nature articles. On 18 March, in response to receiving a copy of their preliminary manuscript, Wilkins penned the following: "I think you're a couple of old rogues, but you may well have something". Crick and Watson then published their model in Nature on 25 April 1953 in an article describing the double-helical structure of DNA with only a footnote acknowledging "having been stimulated by a general knowledge of" Franklin and Wilkins' "unpublished" contribution. Actually, although it was the bare minimum, they had just enough specific knowledge of Franklin and Gosling's data upon which to base their model. As a result of a deal struck by the two laboratory directors, articles by Wilkins and Franklin, which included their X-ray diffraction data, were modified and then published second and third in the same issue of Nature, seemingly only in support of the Crick and Watson theoretical paper which proposed a model for the B form of DNA. Weeks later, on 10 April, Franklin wrote to Crick for permission to see their model. Franklin retained her scepticism for premature model building even after seeing the Watson–Crick model, and remained unimpressed. She is reported to have commented, "It's very pretty, but how are they going to prove it?" As an experimental scientist, Franklin seems to have been interested in producing far greater evidence before publishing-as-proven a proposed model. As such, her response to the Watson–Crick model was in keeping with her cautious approach to science. Most of the scientific community hesitated several years before accepting the double helix proposal. At first mainly geneticists embraced the model because of its obvious genetic implications. Birkbeck College Franklin left King's College London in mid-March 1953 for Birkbeck College, in a move that had been planned for some time and that she described (in a letter to Adrienne Weill in Paris) as "moving from a palace to the slums ... but pleasanter all the same." She was recruited by physics department chair John Desmond Bernal, a crystallographer who was a communist, known for promoting women crystallographers. Her new laboratories were housed in 21 Torrington Square, one of a pair of dilapidated and cramped Georgian houses containing several different departments; Franklin frequently took Bernal to task over the careless attitudes of some of the other laboratory staff, notably after workers in the pharmacy department flooded her first-floor laboratory with water on one occasion. Despite the parting words of Bernal to stop her interest in nucleic acids, she helped Gosling to finish his thesis, although she was no longer his official supervisor. Together they published the first evidence of double helix in the A form of DNA in the 25 July issue of Nature. At the end of 1954, Bernal secured funding for Franklin from the Agricultural Research Council (ARC), which enabled her to work as a senior scientist supervising her own research group. John Finch, a physics student from King's College London, subsequently joined Franklin's group, followed by Kenneth Holmes, a Cambridge graduate, in July 1955. Despite the ARC funding, Franklin wrote to Bernal that the existing facilities remained highly unsuited for conducting research "...my desk and lab are on the fourth floor, my X-ray tube in the basement, and I am responsible for the work of four
