103 Berry, George
SUBJECT AREA: Agricultural and food technology[br]b. Missouri, USA fl. 1880s[br]American farmer who developed the first steam-powered, self-propelled combine harvester.[br]Born in Missouri, George Berry moved to a 4,000 acre (1,600 hectare) farm at Lindsay in California, and between 1881 and 1886 built himself a steam-driven combine harvester. Berry's machine was the first self-propelled harvester and the first to use straw as a fuel. A single boiler powered two engines: a 26 hp (19 kW) Mitchell Fisher engine provided the forward drive, whilst a 6 hp (4 kW) Westinghouse engine drove the threshing mechanism. Cleaned straw was passed by conveyor back to the firebox, where it provided the main fuel. The original machine had a 22 ft cut, but a later machine extended this to 40 ft and harvested 50 acres a day, although on one occasion it achieved the distinction of being the first harvester to cut over 100 acres in one day. The traction engine used for motive power was removable and was used after harvest for ploughing. It was the first engine to be capable of forward and reverse motion.In later life Berry moved into politics, becoming a member of the California Senate for Inyo and Tulare in the 1890s.[br]Further ReadingG.Quick and W.Buchele, 1978, The Grain Harvesters, American Society of Agricultural Engineers (gives an account of combine-harvester development).AP -
104 Bloch, Jacob
SUBJECT AREA: Textiles[br]fl. 1888[br]European inventor of a machine for cutting layers of cloth.[br]In mass production of garments, layers of cloth are laid out on top of each other and multiples of each different part are cut out at the same time. The first portable cutting machine was invented by Joseph Bloch in 1888. It was operated from a DC electricity supply and had a circular knife, which was difficult to use when cutting round curves. Therefore the cloth had to be raised on curves so that it would reach the furthest part of the circular blade. In the same year in the USA, G.P.Eastman produced a vertically reciprocating cutting machine with a straight blade.[br]Further ReadingC.Singer (ed.), 1978, A History of Technology, Vol. VI, Oxford: Clarendon Press (describes Bloch's invention).I.McNeil (ed.), 1990, An Encyclopaedia of the History of Technology, London: Routledge, pp. 850–2 (provides a brief description of the making-up trade).D.Sinclair, "The current climate for research and development in the European-clothing industry with particular reference to single ply cutting", unpublished MSc thesis, Salford University (discusses developments in garment production).RLH -
105 Budding, Edwin Beard
SUBJECT AREA: Domestic appliances and interiors[br]b. c.1796 Bisley (?), Gloucestershire, Englandd. 1846 Dursley, Gloucestershire, England[br]English inventor of the lawn mower.[br]Budding was an engineer who described himself as a mechanic on his first patent papers and as a manager in later applications.A rotary machine had been developed at Brimscombe Mill in Stroud for cutting the pile on certain clothes and Budding saw the potential of this principle for a machine for cutting grass on lawns. It is not clear whether Budding worked for the Lewis family, who owned the mill, or whether he saw the machines during their manufacture at the Phoenix Foundry. At the age of 35 Budding entered into partnership with John Ferrabee, who had taken out a lease on Thrupp Mill. They reached an agreement in which Ferrabee would pay to obtain letter patent on the mower and would cover all the development costs, after which they would have an equal share in the profits. The agreement also allowed Ferrabee to license the manufacture of the machine and in 1832 he negotiated with the agricultural manufacturer Ransomes, allowing them to manufacture the mower.Budding invented a screw-shifting spanner at a time when he might have been working as a mechanic at Thrupp Mill. He later rented a workshop in which he produced Pepperbox pistols. In the late 1830s he moved to Dursley, where he became Manager for Mr G.Lister, who made clothing machinery. Together they patented an improved method of making cylinders for carding engines, but Budding required police protection from those who saw their jobs threatened by the device. He made no fortune from his inventions and died at the age of 50.[br]Further ReadingH.A.Randall, 1965–6 "Some mid-Gloucestershire engineers and inventors", Transactions of the Newcomen Society 38:89–96 (looks at the careers of both Budding and Ferrabee).AP -
106 Charpy, Augustin Georges Albert
SUBJECT AREA: Metallurgy[br]b. 1 September 1865 Ouillins, Rhône, Franced. 25 November 1945 Paris, France[br]French metallurgist, originator of the Charpy pendulum impact method of testing metals.[br]After graduating in chemistry from the Ecole Polytechnique in 1887, Charpy continued to work there on the physical chemistry of solutions for his doctorate. He joined the Laboratoire d'Artillerie de la Marine in 1892 and began to study the structure and mechanical properties of various steels in relation to their previous heat treatment. His first memoir, on the mechanical properties of steels quenched from various temperatures, was published in 1892 on the advice of Henri Le Chatelier. He joined the Compagnie de Chatillon Commentry Fourchamboult et Decazeville at their steelworks in Imphy in 1898, shortly after the discovery of Invar by G.E. Guillaume. Most of the alloys required for this investigation had been prepared at Imphy, and their laboratories were therefore well equipped with sensitive and refined dilatometric facilities. Charpy and his colleague L.Grenet utilized this technique in many of their earlier investigations, which were largely concerned with the transformation points of steel. He began to study the magnetic characteristics of silicon steels in 1902, shortly after their use as transformer laminations had first been proposed by Hadfield and his colleagues in 1900. Charpy was the first to show that the magnetic hysteresis of these alloys decreased rapidly as their grain size increased.The first details of Charpy's pendulum impact testing machine were published in 1901, about two years before Izod read his paper to the British Association. As with Izod's machine, the energy of fracture was measured by the retardation of the pendulum. Charpy's test pieces, however, unlike those of Izod, were in the form of centrally notched beams, freely supported at each end against rigid anvils. This arrangement, it was believed, transmitted less energy to the frame of the machine and allowed the energy of fracture to be more accurately measured. In practice, however, the blow of the pendulum in the Charpy test caused visible distortion in the specimen as a whole. Both tests were still widely used in the 1990s.In 1920 Charpy left Imphy to become Director-General of the Compagnie des Aciéries de la Marine et Homecourt. After his election to the Académie des Sciences in 1918, he came to be associated with Floris Osmond and Henri Le Chatelier as one of the founders of the "French School of Physical Metallurgy". Around the turn of the century he had contributed much to the development of the metallurgical microscope and had helped to introduce the Chatelier thermocouple into the laboratory and to industry. He also popularized the use of platinum-wound resistance furnaces for laboratory purposes. After 1920 his industrial responsibilities increased greatly, although he continued to devote much of his time to teaching at the Ecole Supérieure des Mines in Paris, and at the Ecole Polytechnique. His first book, Leçons de Chimie (1892, Paris), was written at the beginning of his career, in association with H.Gautier. His last, Notions élémentaires de sidérurgie (1946, Paris), with P.Pingault as co-author, was published posthumously.[br]BibliographyCharpy published important metallurgical papers in Comptes rendus… Académie des Sciences, Paris.Further ReadingR.Barthélémy, 1947, "Notice sur la vie et l'oeuvre de Georges Charpy", Notices et discours, Académie des Sciences, Paris (June).M.Caullery, 1945, "Annonce du décès de M.G.

107 Goulding, John
SUBJECT AREA: Textiles[br]b. 1791 Massachusetts, USA d. 1877[br]American inventor of an early form of condenser carding machine.[br]The condenser method of spinning was developed chiefly by manufacturers and machine makers in eastern Massachusetts between 1824 and 1826. John Goulding, a machinist from Dedham in Massachusetts, combined the ring doffer, patented by Ezekiel Hale in 1825, and the revolving twist tube, patented by George Danforth in 1824; with the addition of twisting keys in the tubes, the carded woollen sliver could be divided and then completely and continuously twisted. He divided the carded web longitudinally with the ring doffer and twisted these strips to consolidate them into slubbings. The dividing was carried out by covering the periphery of the doffer cylinder with separate rings of card clothing and spacing these rings apart by rings of leather, so that instead of width-way detached strips leaving the card, the strips were continuous and did not require piecing. The strips were passed through rotating tubes and wound on bobbins, and although the twist was false it sufficed to compress the fibres together ready for spinning. Goulding patented his invention in both Britain and the USA in 1826, but while his condensers were very successful and within twenty years had been adopted by a high proportion of woollen mills in America, they were not adopted in Britain until much later. Goulding also worked on other improvements to woollen machinery: he developed friction drums, on which the spools of roving from the condenser cards were placed to help transform the woollen jenny into the woollen mule or jack.[br]Bibliography1826, British patent no. 5,355 (condenser carding machine).Further ReadingD.J.Jeremy, 1981, Transatlantic Industrial Revolution.

108 Macmillan, Kirkpatrick
SUBJECT AREA: Land transport[br]b. 1810d. 1878[br]Scottish inventor and builder of the first pedal-operated bicycle.[br]Macmillan was the blacksmith at the village of Courthill, Dumfriesshire, Scotland. Before 1839, bicycles were of the draisienne or hobby-horse type, which were propelled by the rider's feet pushing alternately on the ground. Macmillan was the first to appreciate that two wheels placed in line could be balanced while being propelled by means of treadles and cranks fitted to one of the axles. His machine, completed in 1839, had wooden wheels shod with iron tyres, and a curved wooden frame which was forked to take the rear axle; the front, steering wheel was carried in an iron fork. The axles ran in brass bearings. Cranks were keyed to the rear axle which was driven by rods connected to two swinging arms; these were pivotted from the frame near the pivot of the front fork, and had foot treadles at their lower ends. Macmillan frequently rode this machine the 22.5 km (14 miles) from Courthill to Dumfries. In 1842 he was fined five shillings at the Gorbals Police Court for knocking over a child at the end of a 64 km (40 mile) ride from Courthill to Glasgow.Although several people copied Macmillan's machine over the next twenty years and it anticipated the rear-driven safety bicycle by some forty years, it did not prove popular.[br]Further ReadingC.F.Caunter, 1955, The History and Development of Cycles, London: HMSO.IMcN -
109 McKay, Hugh Victor
SUBJECT AREA: Agricultural and food technology[br]b. c. 1866 Drummartin, Victoria, Australiad. 21 May 1926 Australia[br]Australian inventor and manufacturer of harvesting and other agricultural equipment.[br]A farmer's son, at the age of 17 McKay developed modifications to the existing stripper harvester and created a machine that would not only strip the seed from standing corn, but was able to produce a threshed, winnowed and clean sample in one operation. The prototype was produced in 1884 and worked well on the two acres of wheat that had been set aside on the family farm. By arrangement with a Melbourne plough maker, five machines were made and sold for the 1885 season. In 1886 the McKay Harvester Company was formed, with offices at Ballarat, from which the machines, built by various companies, were sold. The business expanded quickly, selling sixty machines in 1888, and eventually rising to the production of nearly 2,000 harvesters in 1905. The name "Sunshine" was given to the harvester, and the "Sun" prefix was to appear on all other implements produced by the company as it diversified its production interests. In 1902 severe drought reduced machinery sales and left 2,000 harvesters unsold. McKay was forced to look to export markets to dispose of his surplus machines. By 1914 a total of 10,000 machines were being exported annually. During the First World War McKay was appointed to the Business Board of the Defence Department. Increases in the scale of production resulted in the company moving to Melbourne, where it was close to the port of entry of raw materials and was able to export the finished article more readily. In 1909 McKay produced one of the first gas-engined harvesters, but its cost prevented it from being more than an experimental prototype. By this time McKay was the largest agricultural machinery manufacturer in the Southern hemisphere, producing a wide range of implements, including binders. In 1916 McKay hired Headlie Taylor, who had developed a machine capable of harvesting fallen crops. The jointly developed machine was a major success, coming as it did in what would otherwise have been a disastrous Australian harvest. Further developments included the "Sun Auto-header" in 1923, the first of the harvesting machines to adopt the "T" configuration to be seen on modern harvesters. The Australian market was expanding fast and a keen rivalry developed between McKay and Massey Harris. Confronted by the tariff regulations with which the Australian Government had protected its indigenous machinery industry since 1906, Massey Harris sold all its Australian assets to the H.V. McKay company in 1930. Twenty-three years later Massey Ferguson acquired the old Sunshine works and was still operating from there in the 1990s.Despite a long-running history of wage disputes with his workforce, McKay established a retiring fund as well as a self-help fund for distressed cases. Before his death he created a charitable trust and requested that some funds should be made available for the "aerial experiments" which were to lead to the establishment of the Flying Doctor Service.[br]Principal Honours and DistinctionsCBE.Further ReadingGraeme Quick and Wesley Buchele, 1978, The Grain Harvesters, American Society of Agricultural Engineers (devotes a chapter to the unique development of harvesting machinery which took place in Australia).AP -
110 Pennington, William
SUBJECT AREA: Textiles[br]ft. 1750 England[br]English patentee of a machine for making holes in the leather backing used for card clothing.[br]Prior to the spinning process, the raw cotton or wool must be prepared. One stage of the preparation is carding, in which the mass of fibres is drawn out and disentangled before being rolled up into a sliver or rollrag. At first natural teazels were mounted on boards. The wool was caught round their hooks and pulled out as the hand cards were drawn across each other. It is not known when iron wire hooks inserted through a leather backing were substituted for teazels, but in 1750 William Pennington took out a patent, for a machine to make the holes in the leather backing so that the bent wires could be inserted more easily and more regularly. Soon after this a machine for making the complete card clothing was made by Robert Kay.[br]Bibliography1750, British patent no. 657.Further ReadingR.L.Hills, 1970, Power in the Industrial Revolution, Manchester (includes a brief account of the development of card-clothing machines).RLH -
111 Ridley, John
SUBJECT AREA: Agricultural and food technology[br]b. 1806 West Boldon, Co. Durham, Englandd. 1887 Malvern, England[br]English developer of the stripper harvester which led to a machine suited to the conditions of Australia and South America.[br]John Ridley was a preacher in his youth, and then became a mill owner before migrating to Australia with his wife and daughters in 1839. Intending to continue his business in the new colony, he took with him a "Grasshopper" overbeam steam-engine made by James Watt, together with milling equipment. Cereal acreages were insufficient for the steam power he had available, and he expanded into saw milling as well as farming 300 acres. Aware of the Adelaide trials of reaping machines, he eventually built a prototype using the same principles as those developed by Wrathall Bull. After a successful trial in 1843 Ridley began the patent procedure in England, although he never completed the project. The agricultural press was highly enthusiastic about his machine, but when trials took place in 1855 the award went to a rival. The development of the stripper enabled a spectacular increase in the cereal acreage planted over the next decade. Ridley left Australia in 1853 and returned to England. He built a number of machines to his design in Leeds; however, these failed to perform in the much damper English climate. All of the machines were exported to South America, anticipating a substantial market to be exploited by Australian manufacturers.[br]Principal Honours and DistinctionsIn 1913 a Ridley scholarship was established by the faculty of Agriculture at Adelaide University.Further ReadingG.Quick and W.Buchele, 1978, The Grain Harvesters, American Society of Agricultural Engineers (includes a chapter devoted to the Australian developments).A.E.Ridley, 1904, A Backward Glance (describes Ridley's own story).G.L.Sutton, 1937, The Invention of the Stripper (a review of the disputed claims between Ridley and Bull).L.J.Jones, 1980, "John Ridley and the South Australian stripper", The History ofTechnology, pp. 55–103 (a more detailed study).——1979, "The early history of mechanical harvesting", The History of Technology, pp. 4,101–48 (discusses the various claims to the first invention of a machine for mechanical harvesting).AP -
112 Smith, J.
SUBJECT AREA: Textiles[br]fl. 1830s Scotland[br]Scottish inventor of the first endless chain of flats for carding.[br]Carding by hand required a pair of hand cards. The lump of tangled fibres was teased out by pulling one card across the other to even out the fibres and transfer them onto one of the cards from which they could be rolled up into a rollag or slubbing. When Arkwright began to use cylinder cards, the fibres were teased out as they passed from one cylinder to the next. In order to obtain a greater carding area, he soon introduced smaller cylinders and placed strips of flat card above the periphery of the main cylinder. These became clogged with short fibres and dirt, so they had to be lifted off and cleaned or "stripped" at intervals. The first to invent a self-stripping card was Archibald Buchanan, at the Catrine mills in Ayrshire, with his patent in 1823. In his arrangement each flat was turned upside down and stripped by a rotary brush. This was improved by Smith in 1834 and patented in the same year. Smith fixed the flats on an endless chain so that they travelled around the periphery of the top of the main cylinder. Just after the point where they left the cylinder, Smith placed a rotary brush and a comb to clear the brush. In this way each flat in turn was properly and regularly cleaned.Smith was an able mechanic and Managing Partner of the Deanston mills in Scotland. He visited Manchester, where he was warmly received on the introduction of his machine there at about the same time as he patented it in Scotland. The carding engine he designed was complex, for he arranged a double feed to obtain greater production. While this part of his patent was not developed, his chain or endless flats became the basis used in later cotton carding engines. He took out at least half a dozen other patents for textile machinery. These included two in 1834, the first for a self-acting mule and the second with J.C. Dyer for improvements to winding on to spools. There were further spinning patents in 1839 and 1844 and more for preparatory machinery including carding in 1841 and 1842. He was also interested in agriculture and invented a subsoil plough and other useful things.[br]Bibliography1834, British patent no. 6,560 (self-stripping card). 1834, British patent no. 656 (self-acting mule). 1839, British patent no. 8,054.1841, British patent no. 8,796 (carding machine). 1842, British patent no. 9,313 (carding machine).1844, British patent no. 10,080.Further ReadingE.Leigh, 1875, The Science of Modern Cotton Spinning Manchester (provides a good account of Smith's carding engine).W.English, 1969, The Textile Industry, London (covers the development of the carding engine).RLH -
113 Snodgrass, Neil
SUBJECT AREA: Textiles[br]fl. late 1790s Scotland[br]Scottish inventor of the scutcher for opening and cleaning raw cotton.[br]Raw cotton arrived in Britain in tightly packed bales. Before spinning, the fibres had to be opened out, and dirt, seeds and bits of plant had to be removed. This was an unpleasant and fatiguing job usually carried out by women and children. By 1800 it could be done by two machines. The first stage in opening was the "willow" and then the cotton was passed through the "scutcher" to open it further and give it a more effective cleaning. These machines reduced the labour of the operation to about one-twentieth of what it had been. The scutching machine was constructed by Snodgrass and first used at Houston's mill in Johnstone, near Paisley, in 1797. It was derived from the threshing machine invented by Andrew Meikle of Phantassie in 1786. In the scutcher, revolving bars beat the cotton to separate the fibres from the trash. As the dirt fell out, the cotton was blown forward by a fan and was rolled up into a lap at the end of the machine. Scutchers were not introduced to Manchester until 1808 or 1809 and further improvements were soon made to them.[br]Further ReadingR.L.Hills, 1970, Power in the Industrial Revolution, Manchester (covers the development of the scutcher).W.English, 1970, The Textile Industry, London (provides a brief account).RLH -
114 Wood, Henry Alexander Wise
SUBJECT AREA: Paper and printing[br]b. 1 March 1866 New York, USAd. 9 April 1939 USA[br]American manufacturer and inventor of printing machinery, including a stereotype casting machine.[br]The son of a Congressman and mayor of New York, Wood was educated at Media Academy in Pennsylvania, specializing in scientific subjects. The death of his father in 1881 prevented his going on to college and he went to work at the Campbell Printing and Manufacturing Company, of which he became President in 1896. In the meantime, he had married the daughter of J.L.Brower, the previous head of the company. Later business consolidations brought into being the Wood Newspaper Machine Corporation.Wood was responsible for a series of inventions that brought great benefit to the newspaperprinting processes. Most notable was the Autoplate, patented first in 1900 and finally in 1903. This enabled a whole page of newspaper type to be cast in metal at once, saving much time and effort in the forming of stereotypes; this invention earned him the Elliott Cresson gold medal of the Franklin Institute in 1909. Other inventions were the Autoreel, a high-speed press-feeder device, and the Autopaster, which automatically replaced a spent paper roll with a new one in a newspaper press, without the need to stop the press. Wood's improved presses and inventions increased the speed of newspaper production from 24,000 to 60,000 copies per hour, printed and folded.He was also much interested in aviation and was an early member of the Aero Club of America, becoming its Vice-President for six years. He helped to found the magazine Flying and was its Editor from 1911 to 1919. He had predicted the part played by aircraft and submarines during the Second World War and was invited to join a panel of consulting inventors and engineers to assist the development of the US Navy. He was soon at odds with the authorities, however, and he resigned in 1915. After the war, he spent time in vigorous campaigning against immigration, America's entry into the League of Nations and on many other issues, in all of which he was highly controversial. Nevertheless, he retained his interest in the newspaper-machinery business, remaining President of his company until 1935 and Chairman of the Board thereafter. In 1934 he became Chairman of the NRA Code Authority of the newspaper-machine industry.[br]Further ReadingObituary, 1939, New York Times (10 April).

118 Goldstine, Herman H.
SUBJECT AREA: Electronics and information technology[br]b. 13 September 1913 USA[br]American mathematician largely responsible for the development of ENIAC, an early electronic computer.[br]Goldstine studied mathematics at the University of Chicago, Illinois, gaining his PhD in 1936. After teaching mathematics there, he moved to a similar position at the University of Michigan in 1939, becoming an assistant professor. After the USA entered the Second World War, in 1942 he joined the army as a lieutenant in the Ballistic Missile Research Laboratory at the Aberdeen Proving Ground in Maryland. He was then assigned to the Moore School of Engineering at the University of Pennsylvania, where he was involved with Arthur Burks in building the valve-based Electronic Numerical Integrator and Computer (ENIAC) to compute ballistic tables. The machine was completed in 1946, but prior to this Goldstine had met John von Neumann of the Institute for Advanced Studies (IAS) at Princeton, New Jersey, and active collaboration between them had already begun. After the war he joined von Neumann as Assistant Director of the Computer Project at the Institute of Advanced Studies, Princeton, becoming its Director in 1954. There he developed the idea of computer-flow diagrams and, with von Neumann, built the first computer to use a magnetic drum for data storage. In 1958 he joined IBM as Director of the Mathematical Sciences Department, becoming Director of Development at the IBM Data Processing Headquarters in 1965. Two years later he became a Research Consultant, and in 1969 he became an IBM Research Fellow.[br]Principal Honours and DistinctionsGoldstine's many awards include three honorary degrees for his contributions to the development of computers.Bibliography1946, with A.Goldstine, "The Electronic Numerical Integrator and Computer (ENIAC)", Mathematical Tables and Other Aids to Computation 2:97 (describes the work on ENIAC).1946, with A.W.Burks and J.von Neumann, "Preliminary discussions of the logical design of an electronic computing instrument", Princeton Institute for Advanced Studies.1972, The Computer from Pascal to von Neumann, Princeton University Press.1977, "A brief history of the computer", Proceedings of the American Physical Society 121:339.Further ReadingM.Campbell-Kelly \& M.R.Williams (eds), 1985, The Moore School Lectures (1946), Charles Babbage Institute Report Series for the History of Computing, Vol 9.

119 Kurtz, Thomas E.
SUBJECT AREA: Electronics and information technology[br]b. USA[br]American mathematician who, with Kemeny developed BASIC, a high-level computer language.[br]Kurtz took his first degree in mathematics at the University of California in Los Angeles (UCLA), where he also gained experience in numerical methods as a result of working in the National Bureau of Standards Institute for Numerical Analysis located on the campus. In 1956 he obtained a PhD in statistics at Princeton, after which he took up a post as an instructor at Dartmouth College in Hanover, New Hampshire. There he found a considerable interest in computing was already in existence, and he was soon acting as the Dartmouth contact with the New England Regional Computer Center at Massachusetts Institute of Technology, an initiative partly supported by IBM. With Kemeny, he learned the Share Assembly Language then in use, but they were concerned about the difficulty of programming computers in assembly language and of teaching it to students and colleagues at Dartmouth. In 1959 the college obtained an LGP-30 computer and Kurtz became the first Director of the Dartmouth Computer Center. However, the small memory (4 k) of this 30-bit machine precluded its use with the recently available high-level language Algol 58. Therefore, with Kemeny, he set about developing a simple language and operating system that would use simple English commands and be easy to learn and use. This they called the Beginners All-purpose Symbolic Instruction Code (BASIC). At the same time they jointly supervised the design and development of a time-sharing system suitable for college use, so that by 1964, when Kurtz became an associate professor of mathematics, they had a fully operational BASIC system; by 1969 a sixth version was already in existence. In 1966 Kurtz left Dartmouth to become a Director of the Kiewit Computer Center, and then, in 1975, he became a Director of the Office of Academic Computing; in 1978 he returned to Dartmouth as Professor of Mathematics. He also served on various national committees.[br]Bibliography1964, with J.G.Kemeny, BASIC Instruction Manual: Dartmouth College (for details of the development of BASIC etc.).1968, with J.G.Kemeny "Dartmouth time-sharing", Science 223.Further ReadingR.L.Wexelblat, 1981, History of Programming Languages, London: Academic Press (a more general view of the development of computer languages).KF -
