121 Darby, Abraham
SUBJECT AREA: Metallurgy[br]b. 1678 near Dudley, Worcestershire, Englandd. 5 May 1717 Madely Court, Coalbrookdale, Shropshire, England[br]English ironmaster, inventor of the coke smelting of iron ore.[br]Darby's father, John, was a farmer who also worked a small forge to produce nails and other ironware needed on the farm. He was brought up in the Society of Friends, or Quakers, and this community remained important throughout his personal and working life. Darby was apprenticed to Jonathan Freeth, a malt-mill maker in Birmingham, and on completion of his apprenticeship in 1699 he took up the trade himself in Bristol. Probably in 1704, he visited Holland to study the casting of brass pots and returned to Bristol with some Dutch workers, setting up a brassworks at Baptist Mills in partnership with others. He tried substituting cast iron for brass in his castings, without success at first, but in 1707 he was granted a patent, "A new way of casting iron pots and other pot-bellied ware in sand without loam or clay". However, his business associates were unwilling to risk further funds in the experiments, so he withdrew his share of the capital and moved to Coalbrookdale in Shropshire. There, iron ore, coal, water-power and transport lay close at hand. He took a lease on an old furnace and began experimenting. The shortage and expense of charcoal, and his knowledge of the use of coke in malting, may well have led him to try using coke to smelt iron ore. The furnace was brought into blast in 1709 and records show that in the same year it was regularly producing iron, using coke instead of charcoal. The process seems to have been operating successfully by 1711 in the production of cast-iron pots and kettles, with some pig-iron destined for Bristol. Darby prospered at Coalbrookdale, employing coke smelting with consistent success, and he sought to extend his activities in the neighbourhood and in other parts of the country. However, ill health prevented him from pursuing these ventures with his previous energy. Coke smelting spread slowly in England and the continent of Europe, but without Darby's technological breakthrough the ever-increasing demand for iron for structures and machines during the Industrial Revolution simply could not have been met; it was thus an essential component of the technological progress that was to come.Darby's eldest son, Abraham II (1711–63), entered the Coalbrookdale Company partnership in 1734 and largely assumed control of the technical side of managing the furnaces and foundry. He made a number of improvements, notably the installation of a steam engine in 1742 to pump water to an upper level in order to achieve a steady source of water-power to operate the bellows supplying the blast furnaces. When he built the Ketley and Horsehay furnaces in 1755 and 1756, these too were provided with steam engines. Abraham II's son, Abraham III (1750–89), in turn, took over the management of the Coalbrookdale works in 1768 and devoted himself to improving and extending the business. His most notable achievement was the design and construction of the famous Iron Bridge over the river Severn, the world's first iron bridge. The bridge members were cast at Coalbrookdale and the structure was erected during 1779, with a span of 100 ft (30 m) and height above the river of 40 ft (12 m). The bridge still stands, and remains a tribute to the skill and judgement of Darby and his workers.[br]Further ReadingA.Raistrick, 1989, Dynasty of Iron Founders, 2nd edn, Ironbridge Gorge Museum Trust (the best source for the lives of the Darbys and the work of the company).H.R.Schubert, 1957, History of the British Iron and Steel Industry AD 430 to AD 1775, London: Routledge \& Kegan Paul.LRD -
122 Moxon, Joseph
SUBJECT AREA: Paper and printing[br]b. 8 August 1627 Wakefield, Yorkshire, England d. 1700[br]English publisher of mathematical and technical books.[br]Moxon acquired a knowledge of mathematics, map making and many technical arts, to which, as a result of some time spent in Holland, he added a knowledge of languages. By 1657 he was established in Cornhill in London, "at the sign of Atlas", where he published and sold "all manner of mathematical books or instruments and maps whatsoever". Soon after 1660, Moxon was appointed Hydrographer to King Charles II, i.e. map and chart printer and seller. By this time his shop was on Ludgate Hill, and in 1683 it had moved to the west side of Fleet Ditch, but retained its name "at the sign of Atlas". Moxon's most important publishing venture was a series of handbooks, never completed, entitled Mechanick Exercises or the Doctrine of Handy- Works. It was begun in 1677 and was intended to be published monthly and cover the whole range of practical techniques, such as metal-turning and woodworking. However, the series was suspended after a year or so due to the effects of the Popish Plot, which "took off the minds of my few customers from buying". He resumed publication with the most important of these works, Mechanick Exercises on the Whole Art of Printing, which appeared in 1683–4. Although printing had been invented more than two centuries earlier, this is the first detailed account in any language of printing, and includes all aspects of the process: type casting, setting, and construction and operation of the press itself, together with the organization of the printing shop. It served as the basis of future handbooks throughout the age of the hand press.[br]Principal Honours and DistinctionsFRS 1678.Bibliography1683–4, Mechanick Exercises on the Whole Art of Printing, reprinted 1958, eds H.Davies and H.Carter, London: Oxford University Press (this facsimile reprint includes the most detailed account of Moxon's life and work, with full bibliographical details of the book itself).LRD -
123 Ransome, Robert
SUBJECT AREA: Agricultural and food technology[br]b. 1753 Wells, Norfolk, Englandd. 1830 England[br]English inventor of a self-sharpening ploughshare and all-metal ploughs with interchangeable pans.[br]The son of a Quaker schoolmaster, Ransome served his apprenticeship with a Norfolk iron manufacturer and then went into business on his own in the same town, setting up one of the first brass and iron foundries in East Anglia. At an early stage of his career he was selling into Norfolk and Suffolk, well beyond the boundaries to be expected from a local craftsman. He achieved this through the use of forty-seven agents acting on his behalf. In 1789, with one employee and £200 capital, he transferred to Ipswich, where the company was to remain and where there was easier access to both raw materials and his markets. It was there that he discovered that cooling one part of a metal share during its casting could result in a self-sharpening share, and he patented the process in 1785.Ransome won a number of awards at the early Bath and West shows, a fact which demonstrates the extent of his markets. In 1808 he patented an all-metal plough made up of interchangeable parts, and the following year was making complete ploughs for sale. With interchangeable parts he was able to make composite ploughs suitable for a wide variety of conditions and therefore with potential markets all over the country.In 1815 he was joined by his son James, and at about the same time by William Cubitt. With the expertise of the latter the firm moved into bridge building and millwrighting, and was therefore able to withstand the agricultural depression which began to affect other manufacturers from about 1815. In 1818, under Cubitt's direction, Ransome built the gas-supply system for the town of Ipswich. In 1830 his grandson James Ransome joined the firm, and it was under his influence that the agricultural side was developed. There was a great expansion in the business after 1835.[br]Further ReadingJ.E.Ransome, 1865, Ploughs and Ploughing at the Royal Agricultural College at Cirencester in 1865, in which he outlined the accepted theories of the day.J.B.Passmore, 1930, The English Plough, Reading: University of Reading (provides a history of plough development from the eighth century to the in ter-war period).Ransome's Royal Records 1789–1939, produced by the company; D.R.Grace and D.C.Phillips, 1975, Ransomes of Ipswich, Reading: Institute of Agricultural History, Reading University (both provide information about Ransome in a more general account about the company and its products; Reading University holds the company archives).AP -
124 Szilard, Leo
SUBJECT AREA: Weapons and armour[br]b. 11 February 1898 Budapest, Hungaryd. 30 May 1964 La Jolla, California, USA[br]Hungarian (naturalized American in 1943) nuclear-and biophysicist.[br]The son of an engineer, Szilard, after service in the Austro-Hungarian army during the First World War, studied electrical engineering at the University of Berlin. Obtaining his doctorate there in 1922, he joined the faculty and concentrated his studies on thermodynamics. He later began to develop an interest in nuclear physics, and in 1933, shortly after Hitler came to power, Szilard emigrated to Britain because of his Jewish heritage.In 1934 he conceived the idea of a nuclear chain reaction through the breakdown of beryllium into helium and took out a British patent on it, but later realized that this process would not work. In 1937 he moved to the USA and continued his research at the University of Columbia, and the following year Hahn and Meitner discovered nuclear fission with uranium; this gave Szilard the breakthrough he needed. In 1939 he realized that a nuclear chain reaction could be produced through nuclear fission and that a weapon with many times the destructive power of the conventional high-explosive bomb could be produced. Only too aware of the progress being made by German nuclear scientists, he believed that it was essential that the USA should create an atomic bomb before Hitler. Consequently he drafted a letter to President Roosevelt that summer and, with two fellow Hungarian émigrés, persuaded Albert Einstein to sign it. The result was the setting up of the Uranium Committee.It was not, however, until December 1941 that active steps began to be taken to produce such a weapon and it was a further nine months before the project was properly co-ordinated under the umbrella of the Manhattan Project. In the meantime, Szilard moved to join Enrico Fermi at the University of Chicago and it was here, at the end of 1942, in a squash court under the football stadium, that they successfully developed the world's first self-sustaining nuclear reactor. Szilard, who became an American citizen in 1943, continued to work on the Manhattan Project. In 1945, however, when the Western Allies began to believe that only the atomic bomb could bring the war against Japan to an end, Szilard and a number of other Manhattan Project scientists objected that it would be immoral to use it against populated targets.Although he would continue to campaign against nuclear warfare for the rest of his life, Szilard now abandoned nuclear research. In 1946 he became Professor of Biophysics at the University of Chicago and devoted himself to experimental work on bacterial mutations and biochemical mechanisms, as well as theoretical research on ageing and memory.[br]Principal Honours and DistinctionsAtoms for Peace award 1959.Further ReadingKosta Tsipis, 1985, Understanding Nuclear Weapons, London: Wildwood House, pp. 16–19, 26, 28, 32 (a brief account of his work on the atomic bomb).A collection of his correspondence and memories was brought out by Spencer Weart and Gertrud W.Szilard in 1978.CM -
