First edition. DISCOVERY OF THE STRUCTURE OF DNA. First edition, in the rare offprint form, of one of the most important scientific papers of the twentieth century, which "records the discovery of the molecular structure of deoxyribonucleic acid (DNA), the main component of chromosomes and the material that transfers genetic characteristics in all life forms. Publication of this paper initiated the science of molecular biology. Forty years after Watson and Crick's discovery, so much of the basic understanding of medicine and disease has advanced to the molecular level that their paper may be considered the most significant single contribution to biology and medicine in the twentieth century" (One Hundred Books Famous in Medicine, p. 362). "The discovery in 1953 of the double helix, the twisted-ladder structure of deoxyribonucleic acid (DNA), by James Watson and Francis Crick marked a milestone in the history of science and gave rise to modern molecular biology, which is largely concerned with understanding how genes control the chemical processes within cells. In short order, their discovery yielded ground-breaking insights into the genetic code and protein synthesis. During the 1970s and 1980s, it helped to produce new and powerful scientific techniques, specifically recombinant DNA research, genetic engineering, rapid gene sequencing, and monoclonal antibodies, techniques on which today's multi-billion dollar biotechnology industry is founded. Major current advances in science, namely genetic fingerprinting and modern forensics, the mapping of the human genome, and the promise, yet unfulfilled, of gene therapy, all have their origins in Watson and Crick's inspired work. The double helix has not only reshaped biology, it has become a cultural icon, represented in sculpture, visual art, jewelry, and toys" (Francis Crick Papers, National Library of Medicine, profiles./SC/Views/Exhibit/narrative/). In 1962, Watson, Crick, and Wilkins shared the Nobel Prize in Physiology or Medicine "for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material." In 1869, the Swiss physiological chemist Friedrich Miescher (1844-95) first identified what he called 'nuclein' inside the nuclei of human white blood cells. (The term 'nuclein' was later changed to 'nucleic acid' and eventually to 'deoxyribonucleic acid,' or 'DNA.') Miescher's plan was to isolate and characterize not the nuclein (which nobody at that time realized existed) but instead the protein components of leukocytes (white blood cells). Miescher thus made arrangements for a local surgical clinic to send him used, pus-coated patient bandages; once he received the bandages, he planned to wash them, filter out the leukocytes, and extract and identify the various proteins within the white blood cells. But when he came across a substance from the cell nuclei that had chemical properties unlike any protein, including a much higher phosphorous content and resistance to proteolysis (protein digestion), Miescher realized that he had discovered a new substance. Sensing the importance of his findings, Miescher wrote, "It seems probable to me that a whole family of such slightly varying phosphorous-containing substances will appear, as a group of nucleins, equivalent to proteins". But Miescher's discovery of nucleic acids was not appreciated by the scientific community, and his name had fallen into obscurity by the 20th century. "Researchers working on DNA in the early 1950s used the term 'gene' to mean the smallest unit of genetic information, but they did not know what a gene actually looked like structurally and chemically, or how it was copied, with very few errors, generation after generation. In 1944, Oswald Avery had shown that DNA was the 'transforming principle,' the carrier of hereditary information, in pneumococcal bacteria. Nevertheless, many scientists continued to believe that DNA had a structure too uniform and simple.

First edition. DISCOVERY OF THE STRUCTURE OF DNA. SIGNED BY ALL BUT ONE OF THE AUTHORS. First edition, offprint, signed by Watson, Crick, Wilkins, Gosling, Stokes & Wilson, i.e. six of the seven authors. We know of no copy signed by Franklin, and strongly doubt that any such copy exists. Furthermore this copy is, what we believe to be, just one of three copies signed by six authors. One of the most important scientific papers of the twentieth century, which "records the discovery of the molecular structure of deoxyribonucleic acid (DNA), the main component of chromosomes and the material that transfers genetic characteristics in all life forms.

This copy is signed by all the authors except Rosalind Franklin (1920 1958) - we have never seen or heard of a copy signed by her.

A VERY FINE SET OF THE DNA PAPERS. First edition, in the form in which they first appeared, of six crucial papers documenting the discovery of the structure of DNA and the mechanism of the genetic code. The first is Watson & Crick's paper 'Molecular Structure of Nucleic Acids: A Structure for Deoxyribose Nucleic Acid', which "records the discovery of the molecular structure of deoxyribonucleic acid (DNA), the main component of chromosomes and the material that transfers genetic characteristics in all life forms. Publication of this paper initiated the science of molecular biology. Forty years after Watson and Crick's discovery, so much of the basic understanding of medicine and disease has advanced to the molecular level that their paper may be considered the most significant single contribution to biology and medicine in the twentieth century" (One Hundred Books Famous in Medicine, p. 362). Watson & Crick's paper is here accompanied by their paper published one month later, 'Genetical Implications of the Structure of Deoxyribonucleic Acid,' "in which they elaborated on their proposed DNA replication mechanism" (ibid.), together with one of the papers which provided the experimental data confirming their proposed structure, a follow up to 'Molecular Structure of Deoxypentose Nucleic Acids' by Wilkins et al. Also included is the 1961 paper 'General Nature of the Genetic Code for Proteins,' documenting Crick's team's efforts to crack the genetic code, amassing evidence suggesting that "the amino-acid sequence along the polypeptide chain of a protein is determined by the sequence of the bases along some particular part of the nucleic acid of the genetic material" (p. 1227), and that each acid was most likely coded by a group of three bases. In 1962, Watson, Crick, and Wilkins shared the Nobel Prize in Physiology or Medicine "for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material." The first three papers were issued together in offprint from, but the journal issue offered here preceded the offprint and is actually rarer on the market. DNA was first isolated by the Swiss physician Friedrich Miescher in 1869, and over the succeeding years many researchers investigated its structure and function, with some arguing that it may be involved in genetic inheritance. By the early 1950s this had become one of the most important questions in biology. Maurice Wilkins of King's College London and his colleague Rosalind Franklin were both working on DNA, with Franklin producing X-ray diffraction images of its structure. Wilkins also introduced his friend Francis Crick to the subject, and Crick and his partner James Watson began their own investigation at the Cavendish Laboratory in Cambridge, focusing on building molecular models. After one failed attempt in which they postulated a triple-helix structure, they were banned by the Cavendish from spending any additional time on the subject. But a year later, after seeing new X-ray diffraction images taken by Franklin (notably the famous 'Photo 51', which is reproduced in the third offered paper), they resumed their work and soon announced that not only had they discovered the double-helix structure of DNA, but even more importantly, that "the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material." When Watson and Crick's paper was submitted for publication in Nature, Sir Lawrence Bragg, the director of the Cavendish Laboratory at Cambridge, and Sir John Randall of King's College agreed that the paper should be published simultaneously with those of two other groups of researches who had also prepared important papers on DNA: Maurice Wilkins, A.R. Stokes, and H.R. Wilson, authors of 'Molecular Structure of Deoxypentose Nucleic Acids,' and Rosalind Franklin and Raymond Gosling, who submitted the paper 'Molecular Configuration in Sodium Thymonucleate.' The three.
