First Edition. WATSON, James; CRICK, Francis; WILKINS, M.H.F; FRANKLIN, Rosalind; et al. "A Structure for Deoxyribose Nucleic Acid" (171: 737-38); WITH: "Molecular Structure of Deoxypentose Nucleic Acids" (171:738-40); WITH: "Molecular Configuration in Sodium Thymonucleate" (171: 740-41); WITH: "Genetical Implications of the Structure of Deoxyribonucleic Acid" (171: 964-67); WITH: "Evidence for 2-Chain Helix in Crystalline Structure of Sodium Deoxyribonucleate" (172: 156-57); WITH: "Heterogeneity of Deoxyribonucleic Acids" (172: 339-42). FROM: Nature: A Weekly Journal of Science, Volumes 171 and 172, January 3, 1953 to December 26, 1953. London: Macmillan and Co., (1953). Thin octavo, disbound, modern stiff paper wrappers. $8800.Six articles extracted from Volumes 171 and 172 of Nature, including the first appearance of the article announcing the most important biological discovery of the 20th century, as well as five follow-up articles further establishing the structure and function of DNA. In these articles in the journal Nature, the most important biological discovery of the 20th century is calmly announced and concisely elucidated in a paper little more than a page long: the key to the deciphering of the genetic code. "It has not escaped our notice," write Watson and Crick near the end of the first paper, "that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material." Neither did it escape the notice of the Nobel Prize committee. In 1962 Crick, Watson and Wilkins received the Nobel Prize in Medicine "for their discoveries concerning the molecular structure of nuclear acids and its significance for information transfer in living material" (Garrison & Morton 256.3; 256.4). Rosalind Franklin mayÑand surely shouldÑhave been included in the award as well were it not for her early death in 1958. These papers document the birth of a new science, Molecular Biology, whose benefits for humanity we are only now beginning to realize. Dibner 200.

First Edition. Offprint, 8vo (210 x 140mm), pp. 14, with two diagrams (including the double helix) and two illustrations from photographs. The three-paper offprint issue, of the primary record of the co-discovery of the molecular structure of DNA, the most transformative moment in twentieth-century biology. Stapled in self-wrappers as issued. Signed by Maurice Wilkins on the first page. Very lightly toned and a coulpe soft creases, near fine. Grolier Club, One Hundred Books Famous in Medicine, 99; Dibner, Heralds of Science, 200. Garrison-Morton 256.3; Judson, Eighth Day of Creation, pp. 145-56. Ex-Dr. Myron Printzmetal. The discovery of DNA's double helix structure emerged from an intense period of competitive collaboration between research teams at Cambridge and King's College London. Watson and Crick's theoretical breakthrough synthesized crucial experimental evidence from multiple sources: Erwin Chargaff's base composition rules demonstrating the 1:1 ratio of adenine to thymine and guanine to cytosine, X-ray crystallographic data revealing DNA's helical structure, and most critically, the precise measurements of backbone positioning and molecular dimensions. Their elegant model proposed complementary base pairing (A-T and C-G) held together by hydrogen bonds, immediately suggesting a mechanism for genetic replication where each strand could serve as a template for its complement. The accompanying papers by Wilkins, Stokes, and Wilson, and by Franklin and Gosling, provided essential experimental validation through X-ray diffraction analysis, creating a unified presentation of both theoretical insight and empirical evidence that established the foundation of molecular biology. The contentious history surrounding this discovery has generated enduring scholarly debate, particularly regarding the systematic marginalization of Rosalind Franklin's contributions. Franklin's meticulous X-ray crystallographic work, conducted with her graduate student Raymond Gosling, had independently determined many key structural features including the antiparallel orientation of DNA strands, the external positioning of phosphate groups, and precise helical parameters. Her famous "Photograph 51" provided definitive evidence of DNA's helical structure, while her systematic analysis of A-form and B-form DNA revealed critical dimensions that enabled Watson and Crick's model construction. As Brenda Maddox documents in "Rosalind Franklin: The Dark Lady of DNA," Franklin's data was shown to Watson and Crick without her knowledge through Maurice Wilkins, creating an ethical controversy that persists in discussions of scientific collaboration and gender bias. Franklin's death from ovarian cancer in 1958, four years before the Nobel Prize was awarded to Watson, Crick, and Wilkins, has intensified debates about recognition and the complex dynamics of mid-twentieth century scientific discovery, with many scholars arguing that her rigorous experimental approach was as fundamental to the breakthrough as the theoretical modeling that received greater acclaim. This publication represents the founding document of modern molecular biology, establishing the conceptual framework for understanding heredity, genetic replication, and the molecular basis of life itself. The discovery immediately suggested mechanisms for protein synthesis and genetic information transfer, creating the theoretical foundation for subsequent developments in genetic engineering, biotechnology, and genomic medicine. As Francis Crick later observed, the structure's elegant simplicitywith its complementary base pairing and antiparallel strandsprovided not merely a static model but a dynamic mechanism explaining how genetic information could be accurately copied and transmitted across generations. The offprint's scientific significance extends far beyond its immediate discovery, representing the moment when biology transformed from a primarily descriptive science into a molecular discipline capable of manipu.…
