Frank Getz Ashbrook was appointed Junior Animal Husbandman, USDA, in 1914. He was placed in charge of the fur animal experiment station in Saratoga Springs in 1923 and in 1924 became in charge of the newly organized Division of Fur Resources. In 1930, Secretary of Sta te Henry L. Stimson appointed Ashbrook as commissioner general to represent the United States at the International Fur Trade Exposition and Congress held in Leipzig, Germany. In 1942 he advised the War Department on the use of furs during wartime.

First edition. The Molecule That Copies Itself. First edition, in the rare three-paper offprint issue - the author's separate that gathers the whole of the 25 April 1953 Nature announcement - of the discovery of the molecular structure of DNA, the double helix, and with it the mechanism by which living things copy their inheritance. The journal's printer reset the three papers of that issue into a single pamphlet for the authors to send to colleagues. This three-paper offprint is far scarcer than the journal itself. Watson and Crick conducted no experiments of their own. Working at the Cavendish Laboratory in Cambridge across eighteen months, they unified the scattered findings of others into a single structure - two helical sugar-phosphate chains wound about a common axis, running in opposite directions, with the four bases paired across the inside of the ladder. The pairing was the whole of it: adenine always to thymine, cytosine always to guanine, so that the sequence of one strand fixes the sequence of the other. From that single constraint followed the answer to the oldest question in biology - how a gene is copied, with near-perfect fidelity, generation upon generation. The structure the paper sets out is exact and spare. Two right-handed helical chains coil about a common axis, the sugar-phosphate backbones on the outside and the paired bases stacked flat within, perpendicular to the axis; a residue recurs every 3.4 ångström along each chain, the helix repeats after ten residues at intervals of 34 ångström, and the whole forms a cylinder some twenty ångström across. Because the phosphates face outward into the surrounding water, solvent and cations reach them freely, and the model so accounts for the high water content of the fibres that Franklin had measured. Crick's lone schematic - two ribbons winding about a vertical fibre axis, the base-pairs drawn as horizontal rods between them - expresses the entire proposal in a single figure; it is this drawing, since become one of the most reproduced diagrams in modern science, that fills the second page of the present pamphlet. Everything the structure asserts is checked against the X-ray evidence: the perpendicular bases, the regular backbones, the antiparallel chains, each a feature the diffraction pattern demanded rather than a freedom the model-builders allowed themselves. The problem they solved was eighty years in the making. In 1869 the Swiss physiological chemist Friedrich Miescher, washing the pus from used surgical bandages to isolate the proteins of white blood cells, instead struck a substance from the cell nucleus richer in phosphorus than any protein and resistant to protein digestion; he named it nuclein and guessed that a whole family of such molecules might exist. The guess was forgotten. By the early 1950s researchers spoke confidently of the gene as the unit of heredity yet could not say what one looked like or how it was copied. Oswald Avery had shown in 1944 that it was DNA, not protein, that carried hereditary character in pneumococcus, but many held the molecule too monotonous - a backbone of four repeating units - to encode the intricacy of a living thing; the genetic material, they reasoned, surely had to be protein, with its twenty amino acids and endless variety. Crick and Watson grasped early that the three-dimensional shape of the gene was the central problem of the new biology, and that without it heredity could not be understood. They seized it at their first meeting, in 1951, and held to it with a single-mindedness that required them to absorb genetics, biochemistry, physical chemistry, and X-ray crystallography at once. Several disconnected results lay waiting to be joined. Alexander Todd had established that the molecular backbone was a regular chain of alternating phosphate and deoxyribose sugar. Erwin Chargaff had found that, however widely the proportions of the four bases varied between species, adenine and thymine always occurred in equal amounts, as did cytosine and guanine. Maurice Wilkins and Rosalind Franklin, at King's College London, had obtained X-ray fibre photographs pointing to a regular helical form. And Linus Pauling, the foremost structural chemist of the age, had not only discovered the single-stranded alpha helix in proteins but pioneered the method - building scale models constrained by known bond lengths and angles - by which Watson and Crick would work. Pauling supplied the spur as well as the tool: in February 1953 he proposed his own structure for DNA, a three-stranded helix with the phosphates at the core, and Watson and Crick, who could see at once that it was electrostatically impossible, feared being overtaken by the only rival capable of beating them. The paper opens by dismissing it, and sets aside in passing a further three-chain model that Bruce Fraser had drafted at King's but never properly published. The decisive correction came from across the office. Jerry Donohue, a visiting American physical chemist sharing the room, told Watson that the textbook forms of two of the bases were wrong: thymine and guanine should be drawn in their keto, not their enol, configuration. Shifting a single hydrogen atom on each accordingly, Watson cut fresh cardboard models and, moving them about his desktop in late February 1953, saw that an adenine-thymine pair and a cytosine-guanine pair had the very same shape and could be held together by hydrogen bonds. At a stroke this accounted for Chargaff's equalities, fitted the bases neatly between the two backbones demanded by the X-ray evidence, and required the chains to run antiparallel. The published paper states its central implication with a now-celebrated restraint - it had 'not escaped our notice' that the pairing at once suggested how the molecule might be copied: part the two strands, and each serves as the template for a new partner. By the account of Watson's memoir, Crick announced to the lunchtime drinkers at The Eagle that they had found the.…
