First edition. TURING AND THE SECRET OF LIFE. First edition of the extremely rare true offprint (without price to front wrapper), of Turing's last major published work, which was "in every respect ahead of its time" (Copeland, p. 510). Taking his cue from the zoologist D'Arcy Thompson, who held that the forms of living things are to be explained in terms of the operation of physical forces and mathematical laws, Turing presents here the first mathematical theory of embryology. "At a time when Crick and Watson were using X-ray diffraction to establish the structure of DNA, Turing was grappling with a theoretical understanding of how information might be spread and diffused at a chemical level. In a classic statement of the scientific method Turing wrote: 'a mathematical model of the growing embryo will be described. This model will be a simplification and an idealisation, and consequently a falsification. It is to be hoped that the features retained for discussion are those of greatest importance in the present state of knowledge'. The result was applied mathematics par excellence. Just as the simple idea of the Turing machine had sent him into fields beyond the boundaries of Cambridge mathematics, so now this simple idea in physical chemistry took him into a region of new mathematical problems" (Hodges, p. 434). "Alan Turing's paper, 'The chemical basis of morphogenesis,' has been hugely influential in a number of areas. In this paper, Turing proposed that biological pattern formation arises in response to a chemical pre-pattern which, in turn, is set up by a process now known as diffusion-driven instability. The genius of this work was that he considered a system which was stable in the absence of diffusion and then showed that the addition of diffusion, which is naturally stabilising, actually caused an instability. Thus, it was the integration of the parts that was as crucial to the understanding of embryological development as the parts themselves patterns emerged or self-organised as a result of the individual parts interacting. To see how far ahead of his time he was, one has to note that it is only now in the post-genomic era of systems biology that the majority of the scientific community has arrived at the conclusion he came to 60 years ago Applications of Turing's work to developmental biology are too numerous to list but include limb development, pigmentation patterning, hair and feather germ formation, tooth morphogenesis, phyllotaxis, hydra patterning and regeneration. Moreover, ideas of self-organization now abound in biology, chemistry and ecology. The stimulus for a lot of this work stems from Turing's original ideas. Although still very controversial, Turing's theory for morphogenesis provided a paradigm shift in our way of thinking" (Maini, in Alan Turing: his work and impact, p. 684). There are two separate issues of 'The chemical basis of morphogenesis', the genuine author's presentation offprint offered here, and a commercially produced reprint; the latter differs from the former only in the presence of a price (eight shillings) at the foot of the front wrapper. ABPC/RBH records the sale of only one copy of this offprint (Christie's, June 12, 2013, lot 136, £13,125) Provenance: Owner's name written in ink to upper right corner of front wrapper; botanist Otto L. Stein (1925-2014). The offprint is accompanied with a signed typed letter from 1956 by R.A. Brooker at the Computing Machine Laboratory Manchester in reply to Stein's request to Turing for a copy of the offprint. "Alan had thought about embryology all the time, fascinated by the fact that how such growth was determined was something 'nobody has yet made the smallest beginnings at finding out.' There had been little advance since Growth and Form [by D'Arcy Thomspon], the 1927 classic that he had read before the war. "The greatest puzzle was that of how biological matter could assemble itself into patterns which were so enormous compared to the size of the cells.

First edition. ALAN TURING'S HANDBOOK FOR THE FERRANTI MARK I THE WORLD'S FIRST COMPUTER PROGRAMMING MANUAL. First edition, extremely rare, of "the world's first computer programming manual" (Jack Copeland & Jason Long, 'Alan Turing: How his Universal Machine became a Musical Instrument,' IEEE Spectrum, 2017), written by Turing for the Ferranti Mark I, the first commercially available electronic digital computer. "In May 1948 Turing resigned from the [National Physical Laboratory]. Work on the ACE [Automatic Computing Engine] had drawn almost to a standstill. [M. H. A.] Newman lured a 'very fed up' Turing to Manchester, where in May 1948 he was appointed Deputy Director of the Computing Machine Laboratory (there being no Director). Turing designed the input mechanism and programming system of, and wrote a programming manual for, the full-scale Manchester computer" (Copeland (ed.), p. 121). The Handbookinstructs users on the programming of the Ferranti Mark I, which was completed in February 1951 and which Turing referred to as the Manchester Electronic Computer Mark II. (The first US commercial machine, the Eckert-Mauchly UNIVAC, appeared a few months later.) The Handbook was written "presumably mostly in the half year gap between the dismantling of the Manchester Mark 1 and the delivery of the Ferranti Mark 1 in February 1951" (University of Manchester, Mark I Documents, online, 2005). Written "mainly for the benefit of those who will actually do programming for the Mark II machine", Turing notes in this introduction that "Electronic computers are intended to carry out any definite rule of thumb process which could have been done by a human operator working in a disciplined but unintelligent manner. The electronic computer should however obtain its results very much more quickly". From 6-15 July 1951 Manchester University hosted an international conference, attended by some 170 delegates, celebrating the installation of the Ferranti Mark 1, at which time the Handbook was probably distributed. The present document is the first of at least three editions of the Handbook, and was apparently written before the machine was fully installed and operating (the library input routines, for instance, are described in the future tense). Turing made little contribution to the later editions because by 1951 his interests had turned back to morphogenesis (in connection with which he used the Mark I for the solution of partial differential equations). This complimentary copy of the first edition is stamped "with the compliments / of A. M. Turing" (the former printed, the latter handwritten in ink, not in Turing's hand). It is accompanied by 9 mimeographed items relating to the Handbook, including a letter from Turing stating the Computing Machine Laboratory at the University of Manchester is willing to "send copies of our library sub-routines to holders of handbooks", and four such subroutines: 'Input. Purpose. To Read from Tape' (1 July 1951); 'English. Purpose. To Print Any Fixed Material with Page Printing' (1 July 1951); 'Roughwrite. Purpose. To Write from Rough Tapes' (1 July 1951); 'Reciproot. Purpose. To Calculate Square Roots and Reciprocal Square Roots' (9 July 1951). The extraordinary rarity of the Handbook might be explained by the fact that only two units of the Ferranti Mark I were actually built. It has been suggested that only "several tens of these manuals were printed" (in all editions) (Lavington). Not on OCLC or Library Hub. RBH lists only one other copy (without the Turing letter and added subroutines). Provenance: Donald Bayley (1921-2020), electronic engineer and collaborator of Alan Turing on 'Delilah,' a functioning portable speech-encryption system, at the MI6 base at Hanslope Park, Buckinghamshire, in 1944. Andrew Hodges writes that Turing spoke to Bayley in 1944 of "building a brain" (uk/publications/); thence by descent to the previous owner. "It was in the Manchester lab, in June 1948, that the first electronic all-purpose, sto.
