1 Murdock (Murdoch), William
[br]b. 21 August 1754 Cumnock, Ayrshire, Scotlandd. 15 November 1839 Handsworth, Birmingham, England[br]Scottish engineer and inventor, pioneer in coal-gas production.[br]He was the third child and the eldest of three boys born to John Murdoch and Anna Bruce. His father, a millwright and joiner, spelled his name Murdock on moving to England. He was educated for some years at Old Cumnock Parish School and in 1777, with his father, he built a "wooden horse", supposed to have been a form of cycle. In 1777 he set out for the Soho manufactory of Boulton \& Watt, where he quickly found employment, Boulton supposedly being impressed by the lad's hat. This was oval and made of wood, and young William had turned it himself on a lathe of his own manufacture. Murdock quickly became Boulton \& Watt's representative in Cornwall, where there was a flourishing demand for steam-engines. He lived at Redruth during this period.It is said that a number of the inventions generally ascribed to James Watt are in fact as much due to Murdock as to Watt. Examples are the piston and slide valve and the sun-and-planet gearing. A number of other inventions are attributed to Murdock alone: typical of these is the oscillating cylinder engine which obviated the need for an overhead beam.In about 1784 he planned a steam-driven road carriage of which he made a working model. He also planned a high-pressure non-condensing engine. The model carriage was demonstrated before Murdock's friends and travelled at a speed of 6–8 mph (10–13 km/h). Boulton and Watt were both antagonistic to their employees' developing independent inventions, and when in 1786 Murdock set out with his model for the Patent Office, having received no reply to a letter he had sent to Watt, Boulton intercepted him on the open road near Exeter and dissuaded him from going any further.In 1785 he married Mary Painter, daughter of a mine captain. She bore him four children, two of whom died in infancy, those surviving eventually joining their father at the Soho Works. Murdock was a great believer in pneumatic power: he had a pneumatic bell-push at Sycamore House, his home near Soho. The pattern-makers lathe at the Soho Works worked for thirty-five years from an air motor. He also conceived the idea of a vacuum piston engine to exhaust a pipe, later developed by the London Pneumatic Despatch Company's railway and the forerunner of the atmospheric railway.Another field in which Murdock was a pioneer was the gas industry. In 1791, in Redruth, he was experimenting with different feedstocks in his home-cum-office in Cross Street: of wood, peat and coal, he preferred the last. He designed and built in the backyard of his house a prototype generator, washer, storage and distribution plant, and publicized the efficiency of coal gas as an illuminant by using it to light his own home. In 1794 or 1795 he informed Boulton and Watt of his experimental work and of its success, suggesting that a patent should be applied for. James Watt Junior was now in the firm and was against patenting the idea since they had had so much trouble with previous patents and had been involved in so much litigation. He refused Murdock's request and for a short time Murdock left the firm to go home to his father's mill. Boulton \& Watt soon recognized the loss of a valuable servant and, in a short time, he was again employed at Soho, now as Engineer and Superintendent at the increased salary of £300 per year plus a 1 per cent commission. From this income, he left £14,000 when he died in 1839.In 1798 the workshops of Boulton and Watt were permanently lit by gas, starting with the foundry building. The 180 ft (55 m) façade of the Soho works was illuminated by gas for the Peace of Paris in June 1814. By 1804, Murdock had brought his apparatus to a point where Boulton \& Watt were able to canvas for orders. Murdock continued with the company after the death of James Watt in 1819, but retired in 1830 and continued to live at Sycamore House, Handsworth, near Birmingham.[br]Principal Honours and DistinctionsRoyal Society Rumford Gold Medal 1808.Further ReadingS.Smiles, 1861, Lives of the Engineers, Vol. IV: Boulton and Watt, London: John Murray.H.W.Dickinson and R.Jenkins, 1927, James Watt and the Steam Engine, Oxford: Clarendon Press.J.A.McCash, 1966, "William Murdoch.

5 Buckle, William
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. 29 July 1794 Alnwick, Northumberland, Englandd. 30 September 1863 London, England[br]English mechanical engineer who introduced the first large screw-cutting lathe to Boulton, Watt \& Co.[br]William Buckle was the son of Thomas Buckle (1759–1849), a millwright who later assisted the 9th Earl of Dundonald (1749–1831) in his various inventions, principally machines for the manufacture of rope. Soon after the birth of William, the family moved from Alnwick to Hull, Yorkshire, where he received his education. The family again moved c.1808 to London, and William was apprenticed to Messrs Woolf \& Edwards, millwrights and engineers of Lambeth. During his apprenticeship he attended evening classes at a mechanical drawing school in Finsbury, which was then the only place of its kind in London.After completing his apprenticeship, he was sent by Messrs Humphrys to Memel in Prussia to establish steamboats on the rivers and lakes there under the patronage of the Prince of Hardenburg. After about four years he returned to Britain and was employed by Boulton, Watt \& Co. to install the engines in the first steam mail packet for the service between Dublin and Holyhead. He was responsible for the engines of the steamship Lightning when it was used on the visit of George IV to Ireland.About 1824 Buckle was engaged by Boulton, Watt \& Co. as Manager of the Soho Foundry, where he is credited with introducing the first large screw-cutting lathe. At Soho about 700 or 800 men were employed on a wide variety of engineering manufacture, including coining machinery for mints in many parts of the world, with some in 1826 for the Mint at the Soho Manufactory. In 1851, following the recommendations of a Royal Commission, the Royal Mint in London was reorganized and Buckle was asked to take the post of Assistant Coiner, the senior executive officer under the Deputy Master. This he accepted, retaining the post until the end of his life.At Soho, Buckle helped to establish a literary and scientific institution to provide evening classes for the apprentices and took part in the teaching. He was an original member of the Institution of Mechanical Engineers, which was founded in Birmingham in January 1847, and a member of their Council from then until 1855. He contributed a number of papers in the early years, including a memoir of William Murdock whom he had known at Soho; he resigned from the Institution in 1856 after his move to London. He was an honorary member of the London Association of Foreman Engineers.[br]Bibliography1850, "Inventions and life of William Murdock", Proceedings of the Institution of Mechanical Engineers 2 (October): 16–26.RTS -

7 Clegg, Samuel
[br]b. 2 March 1781 Manchester, Englandd. 8 January 1861 Haverstock Hill, Hampstead, London, England[br]English inventor and gas engineer.[br]Clegg received scientific instruction from John Dalton, the founder of the atomic theory, and was apprenticed to Boulton \& Watt. While at their Soho factory in Birmingham, he assisted William Murdock with his experiments on coal gas. He left the firm in 1804 and set up as a gas engineer on his own account. He designed and installed gas plant and lighting in a number of factories, including Henry Lodge's cotton mill at Sowerby Bridge and in 1811 the Jesuit College at Stoneyhurst in Lancashire, the first non-industrial establishment to be equipped with gas lighting.Clegg moved to London in 1813 and successfully installed gas lighting at the premises of Rudolf Ackermann in the Strand. His success in the manufacture of gas had earned him the Royal Society of Arts Silver Medal in 1808 for furthering "the art of gas production", and in 1813 it brought him the appointment of Chief Engineer to the first gas company, the Chartered Gas, Light \& Coke Company. He left in 1817, but remained in demand to set up gas works and advise on the formation of gas companies. Throughout this time there flowed from Clegg a series of inventions of fundamental importance in the gas industry. While at Lodge's mill he had begun purifying gas by adding lime to the gas holder, and at Stoneyhurst this had become a separate lime purifier. In 1815, and again in 1818, Clegg patented the wet-meter which proved to be the basis for future devices for measuring gas. He invented the gas governor and, favouring the horizontal retort, developed the form which was to become standard for the next forty years. But after all this, Clegg joined a concern in Liverpool which failed, taking all his possessions with it. He made a fresh start in Lisbon, where he undertook various engineering works for the Portuguese government. He returned to England to find railway construction gathering pace, but he again backed a loser by engaging in the ill-fated atmospheric-rail way project. He was finally discouraged from taking part in further enterprises, but he received a government appointment as Surveying Officer to conduct enquiries in connection with the various Bills on gas that were presented to Parliament. Clegg also contributed to his son's massive treatise on the manufacture of coal gas.[br]Principal Honours and DistinctionsRoyal Society of Arts Silver Medal 1808.Further ReadingMinutes of Proceedings of the Institution of Civil Engineers (1862) 21:552–4.S.Everard, 1949, The History of the Gas light and Coke Company, London: Ernest Benn.LRD -
8 Lebon, Philippe
SUBJECT AREA: Public utilities[br]b. 29 May 1767 Bruchey, near Joinville, Franced. 2 December 1804 Paris, France[br]French pioneer of gas lighting.[br]Lebon was the son of a court official under Louis XV. He entered the Ecole des Ponts et Chaussées and graduated in 1792, by which time he had acquired a considerable reputation as a scientific engineer. He is credited with the invention of the firetube steam boiler and of the superheater, and he also devised an engine to work by gas, but from 1792 until his untimely death he worked mainly on his experiments to produce an inflammable gas for lighting purposes. He submitted a paper on the subject in 1799 to the Institut National and received a patent in the same year. The patent covers the detailed making and application of gas for light, heat and power, and the recovery of by-products. It describes the production of the gas by the carbonization of coal, although Lebon in feet used only wood gas for his experiments and demonstrations. He began demonstrations in a private house in Paris, but these attracted little attention. He achieved wider public interest when he moved to the Hôtel Seignelay, where he started a series of public demonstrations in 1801, but he attracted little profit, and in fact lost his money in his experiments. He then set up a plant near Rouen to manufacture wood tar, but his career was brought to an end by his brutal murder in the Champs Elysées in Paris. William Murdock was working along similar lines in England, although Lebon knew nothing of his experiments. The German entrepreneur F.A. Winsor visited Lebon and managed to discover the essentials of his processes, which he turned to good account in England with the founding of the Gas, Light \& Coke Company.[br]Further ReadingS.T.McCloy, 1952, French Inventors of the Eighteenth Century.A.Fayol, 1943, Philippe Lebon et le gaz d'éclair-age.LRD -
