Hardcover. Condition: Very Good. Hartree, Douglas R. "The ENIAC, an Electronic Computing Machine." Macmillan & Co., London, 1946. In "Nature", Vol 158. July - December, 1946. (52), 956pp, illustrations throughout the text, with the Hartree on pp 500-506, illustrated with three photos including the famous one appearing on page 501showing most of the machine. First printing of the "first paper on an electronic digital computer published in a large-circulation international scientific journal ["Nature"]."--Jeremy Norman's Origins of Cyberspace, 648. [++] The volume is fresh and clean though there are two binding semi-minor issues: first, the cloth boards are a bit thin for a book this size so the front board is slightly bowed. Second, the hinges are starting to break, though it is at this point the paper of the pastedowns and free endpapers that are broken (see pic). Overall, I'd say that this was still a Very Good copy (6/10) [++] The ENIAC (Electronic Numerical Integrator and Computer built 1943-45) was the first large-scale, fully electronic, general-purpose digital computer to operate successfully. It was a decimal non-specific general purpose numerical machine, programmable by physical configuration (via plugboards, switch settings, cable routing). [++] Hartree writes a great introduction to the machine and then proceeds in explaining it to the advanced-general reader. The subheads include "two main classes f computing equipment"; "arithmetical processes, memory, and organisation"; general construction of the ENIAC"; accumulator"; "multiplier"; "divider and square rooter"; "function tables, input and output equipment"; "master programmer"; "set-up and use"; "examples". This is a very well organized and highly readable and important paper.

Hardcover. Condition: very good. first edition. First printing of this critical work in the history of computing and a foundational text that launched a circulation through an international scientific journal. In "Nature", Vol 158. October - December, 1946. Entire volume offred with ENIAC [Electronic Numerical Integrator And Computer] article Pp. 500-506. [Entire volume: Pp. 459-956]. Hartree, a British mathematician, first learned of ENIAC in 1945, when he saw the as-yetuncompleted machine during a visit to the Moore School at the University of Pennsylvania. It was here that this first general-purpose Turing complete digital electronic computer, was built between 1943 and 1946. The first computer course was given at the Moore School in Summer 1946, leading to an explosion in computer development all over the world. Hartree was a participant in the lectures, advising on nonmilitary uses of the ENIAC while being the first Englishman to work with the machine. Later, Hartree helped stimulate the development of more powerful computers like Cambridge University's EDSAC. The ENIAC was 10 feet high, and 3 deepand contained 18,000 vacuum tubes, about 70,000 resistors, 10,000 capacitors, and 6,000 switches. It consumed 140 kilowatts, so much power that when operated the lights in a nearbytown dimmed. Royal 8vo bound in contemporary cloth. Provenance: Bookplates stamps on front free end-papers of the University of Oxford. Near fine and clean. 7œ" - 10". book.

London, Macmillan & Co., 1946. 8vo. Without wrappers. Extracted from "Nature. No. 4015, Saturday, October 12, 1946, Vol. 158". A fine and clean copy. [Hartree:] Pp. 500-6. [Entire offered issue: Pp. 495-528]. First printing of this "first paper on an electronic digital computer published in a large-circulation international scientific journal." (OOC).The ENIAC was the first general-purpose electronic computer. It was a Turing-complete [computationally universal] digital computer capable of being reprogrammed to solve a full range of computing problems."Hartree, a British mathematician, first learned of ENIAC [Electronic Numerical Integrator And Computer] in 1945, when he saw the as-yet uncompleted machine during a visit to the Moore School. In 1946 he returned to the Moore School as a participant in the Moore School lectures, advising on nonmilitary uses of ENIAC" during this time he became the first Englishman to work with the machine. He was the first to bring news of ENIAC to Great Britain, publishing the above article in Nature shourtly after his return from the United States. Although he himself invented no new calculating devices, Hartree's promotion of electronic digital calculating methods in scientific computation helped to stimulate the development of more powerful computers like Cambridge University's EDSAC." (OOC).The ENIAC was compared to today's standard rather large: It was 100 feet long, 10 feet high, and 3 deep and contained 18,000 vacuum tubes, about 70,000 resistors, 10,000 capacitors, and 6,000 switches. It consumed 140 kilowatts of power, so much power that, when operated, the lights in a nearby town dimmed.See: Hook & Norman. Origins of Cyberspace 648.
