"In 1947, frustrated when a failure in one of Bell Lab's relay computers had spoiled a run of data, Hamming began developing the first error-correction codes (now known as Hamming codes), which enabled computers to find and correct single errors in a stretch of data, as well as to discover double errors. Error correction has since been developed into a scientific discipline used in everything from extracting data transmitted from space probes, to recovering jammed communications, to guaranteeing high-quality music from a compact disk (Lee 1995, 361)." [OOC 646] Hamming's paper defined a method for correcting errors in block packages of transmitted data. "He further showed that, in a mathematical sense, these error correcting codes are the best possible codes [known also as 'perfect codes'; there are none shorter" (A. M. Turing Award Portal). Hamming was awarded the A. M. Turing Award in 1968. Before working at Bell, Hamming had been part of the Manhattan Project. "Hamming was the first coding theorist to attract widespread interest in his work" [OOC 646]. "It was an event in 1947 that prompted Hamming to undertake his most famous piece of work. One Friday, while working for Bell Laboratories, he set their pre-computer calculating machines to solving a complex problem and expected the result to be waiting for him when he began work on the following Monday. But when he arrived on Monday, he found that an error had occurred early on in the calculations and the relay-based calculators had been unable to proceed" [Turing Award Portal]. "Hamming began developing the first error-correction codes (now known as Hamming codes), which enabled computers to find and correct single errors.

Cloth. Condición: Near Fine. First Edition. First Edition. 675 pages. 8vo. Blue cloth with previous owner name (C. K. Birdsall) printed at base of spine panel and signature on front wrapper of January issue. Bound privately from separate issues, this copy does not have a volume title page. The entire Volume XXIX offered, containing 4 quarterly issues of the Bell System Technical Journal (only the January issue still retains it's original wrappers as often the case). The article by Hamming is found on pp. 147-160 in the April 1950 issue. Sound and clean, noting a taped tear on page 496. Cloth. Volume XXIX contains work by some of Bell Lab's great minds. It contains work by Hamming in coding theory, Pierce on traveling wave tubes, Shannon on Memory sizing, 2 articles by Hartley and Bardeen on Germanium Point Contacts. It also includes articles on the transistor and triode as they were being developed. A few of the highlights follow.

Error correction has since been developed into a scientific discipline." (Origins of Cyberspace 646) Pierce's massive four installment article on Traveling-Wave Tubes is found in the January, April, July and October issues. Pierce "invented the electron-multiplier tube and electron gun (the basis of television computer monitors, and other visual display equipment), and was instrumental in developing NASA's first communications satellites" (Origins of Cyberspace 836). Issue 3 in this volume includes Shannon's Memory Requirements in a Telephone Exchange. (Origins of Cyberspace 883). "Charles Kennedy ("Ned") Birdsall, Professor Emeritus at the University of California, Berkeley, and a pioneering inventor and educator in microwave tubes and plasma physics.Among numerous awards and honors for his contributions, Ned was selected as the inaugural recipient for the IEEE Marie Sklodowska-Curie Award in 2011. This Technical Field Award is one of the highest awards in the IEEE hierarchy, and recognizes outstanding contributions to the field of Nuclear and Plasma Sciences and Engineering. His citation is "for theoretical investigations and fundamental discoveries involving microwave tubes, electron beam physics and particle-in-cell simulation of plasma physics."

Hamming, Richard Wesley (1915-98). Error detecting and error codes. Bell System Technical Publications, Monograph 1757. 14pp. New York: Bell Telephone Laboratories, October 1950. 277 x 214 mm. Original printed wrappers, perforated for ring binder as issued. Near fine. Library stamp on front wrapper. First Separate Edition. Hamming was the first coding theorist to attract widespread interest in his work. He received his Ph.D. in mathematics from the University of Illinois in 1942, and after a stint at Los Alamos, where his job was to keep the Manhattan Project's IBM relay computers functioning, he went to work at Bell Telephone Laboratories, joining the recently hired Claude Shannon in the mathematics department. In 1947, frustrated when a failure in one of Bell Lab's relay computers had spoiled a run of data, Hamming began developing the first error-correction codes (now known as Hamming codes), which enabled computers to find and correct single errors in a stretch of data, as well as to discover double errors. Error correction has since been developed into a scientific discipline. Hammond's paper first appeared in Vol. 29 of the Bell System Technical Journal, issued in April 1950; the separate monograph version was published six months later. Origins of Cyberspace 646. .
