In 1969, Aaron Klug discovered among the papers Rosalind left at her death a manuscript in draft, dated March 17, 1953, which clearly is what Wilkins was referring to as the paper "all written," and which, though a precursor of the Nature paper, is not identical to it. This also proposes that the B form is helical, that the diameter of the helix is about 20 A, and that "a [crystallographically] very important part of the molecule lies on a helix of this diameter. This can only be the phosphate groups.... Thus, if the structure is helical, we find that the phosphate groups lie on a helix of a diameter about 20 A, and the sugar and base groups must accordingly be turned inwards towards the helical axis."

That she and Gosling had a paper all written in advance of March 17 is in itself interesting. Clearly her own work had reached a point, quite independently of anything that might be going on at Cambridge, where she felt that something worth publishing had been achieved. It has been natural to assume that the paper by her and Gosling which appeared in the April 25 issue of Nature—"Molecular configuration in sodium Thymonucleate"—is the same as the one prepared before the news from Cambridge arrived. This paper discusses both the A and B forms of DNA—including the X-ray photograph of the B form with its helical cross—and, in addition to affirming in published form the location of the phosphate groups on the outside of the molecule, opts for a two-chain helix in the B form, and probably in the A form as well.

…She was close; she was very close; the pieces were beginning to come together in the right way, and it should be remembered that when the pieces begin to fall in place, they often fall quite fast. It should also be emphasized that Rosalind was working essentially alone. The contrast between what was available to Crick and Watson in Cambridge and what Rosalind had for stimulation and support at King's is a staggering one. The perception of the significance of Chargaff's work in providing the 1 : 1 ratio was a splendid one, but it was assisted by a useful conversation with a mathematician.

How long would Watson have wrestled with the problem of the bases had Donohue not been present to suggest the keto instead of the enol forms? Watson had Crick, and Crick had Watson. Rosalind's available source for conversation, advice, helpful speculation was Luzzati, in Paris. Because she had done all her previous crystallographic work in France, she was not even acquainted at the time with the people in England who were working in the field. At King's she had Gosling to talk to, and—to a limited degree—Randall. In view of all this, the pace at which she was moving was, indeed, comparable to that of Watson and Crick, and to see it so is not a case of special pleading.

The notion that accurate statements made by a woman scientist are first to be regarded as likely outpourings of feminism, and only under the strong pressure of irrefutable demonstration as science is Watson's own contribution. So is the fictional "Rosy." Unfortunately these Watsonisms have been widely believed. From scientific publications to discussions in the popular press, both Rosalind's views and her contributions to the solution of the structure of DNA, and sometimes her personality as well, have been either misrepresented or overlooked, and in all cases the source for this treatment appears to have been Watson.

Yet the facts are not all that difficult to ascertain or to grasp. If one thinks of the structure of DNA as a prize awarded at the end of a race, then Rosalind lost the race; by how much is debatable, but by rather less of a margin, it is safe to say, than the one which would have occurred in the opposite direction if Crick and Watson had been required to develop from their own experimentation the data provided, never mind how, from King's. Her contribution to the successful pair who proposed the successful structure was, as Klug has put it, "crucial." And he is worth quoting at length…

It is also worth noting that Rosalind herself had no idea, ever, how crucial her contributions were to the Watson-Crick structure, because she never knew the extent to which her data had passed into their hands or had been talked over with Wilkins. All that she was aware of having provided was what went into her seminar in November 1951, and what she had to say in criticism of the early Watson-Crick model. It is rather interesting to reflect that, if Watson had understood what Rosalind had been saying in that seminar—had taken notes, remembered correctly, or asked modestly for an explanation— he might have brought back to Crick information which would have enabled them, had they put it all together as brilliantly as they later did, to solve the problem much sooner.

But then, it is not really feasible to come home from a lecture, utilize the new learning, and produce a fresh and insightful perception without acknowledging the source of inspiration. In order to make exclusive claims, it is necessary to gather information more indirectly; and as Watson frankly admitted in The Double Helix, this is exactly what he did. There are matters raised by this method of proceeding that offer endless opportunity for scrutiny and debate. They are worthy of scrutiny and debate. The opportunity has been lost in the clouds of glory which surround the Watson-Crick triumph, and the moral of the story, as it has unremittingly been presented, has been a crude and simple one. Winner take all.

After the war the present Institute for Psychosomatic and Psychiatric Research and Training (with 80 beds) was planned, ultimately to be finished and occupied in 1951. In the meantime the psychiatric clinic, with its full-time psychiatrists, social workers, and psychologists, was expanded to occupy a newly completed psychiatric floor in the clinic building. By the time the new building was completed, the Institute had become a multidisciplinary training and research facility. Since its beginnings in 1922, clinical psychiatry at Michael Reese has progressively emphasized psychodynamic principles and since the late 1930's has had an almost exclusively psychoanalytic staff.
Example of Comparative Essay
Although we have considerable responsibility to the community and to other departments of the hospital and clinic, our attempts to maintain quality of service outweigh our concern for quantity. We accept only those patients who we believe can be adequately treated by the available staff of psychiatrists, residents, social workers, and psychologists. For this task we impose no time limitations, although we expect all disciplines to present their patients for staffing and recommendation after therapy has continued for six months to a year. Sometimes this results in termination, reassignment, or altered procedures. Undue prolongation of therapy (a natural tendency in all practice) is also decreased because the psychiatric residents' supervisors are shifted every six months, student social workers leave after a nine-month academic year, and residents eventually terminate their training.
