62 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.

63 Perret, Auguste
[br]b. 12 February 1874 Ixelles, near Brussels, Belgiumd. 26 February 1954 Le Havre (?), France[br]French architect who pioneered and established building design in reinforced concrete in a style suited to the modern movement.[br]Auguste Perret belonged to the family contracting firm of A. \& G.Perret, which early specialized in the use of reinforced concrete. His eight-storey building at 25 bis Rue Franklin in Paris, built in 1902–3, was the first example of frame construction in this material and established its viability for structural design. Both ground plan and façade are uncompromisingly modern, the simplicity of the latter being relieved by unobtrusive faience decoration. The two upper floors, which are set back, and the open terrace roof garden set a pattern for future schemes. All of Perret's buildings had reinforced-concrete structures and this was clearly delineated on the façade designs. The concept was uncommon in Europe at the time, when eclecticism still largely ruled, but was derived from the late nineteenth-century skyscraper façades built by Louis Sullivan in America. In 1905–6 came Perret's Garage Ponthieu in Paris; a striking example of exposed concrete, it had a central façade window glazed in modern design in rich colours. By the 1920s ferroconcrete was in more common use, but Perret still led the field in France with his imaginative, bold use of the material. His most original structure is the Church of Notre Dame at Le Raincy on the outskirts of Paris (1922–3). The imposing exterior with its tall tower in diminishing stages is finely designed, but the interior has magnificence. It is a wide, light church, the segmented vaulted roof supported on slender columns. The whole structure is in concrete apart from the glass window panels, which extend the full height of the walls all around the church. They provide a symphony of colour culminating in deep blue behind the altar. Because of the slenderness of the columns and the richness of the glass, this church possesses a spiritual atmosphere and unimpeded sight and sound of and from the altar for everyone. It became the prototype for churches all over Europe for decades, from Moser in prewar Switzerland to Spence's postwar Coventry Cathedral.In a long working life Perret designed buildings for a wide range of purposes, adhering to his preference for ferroconcrete and adapting its use according to each building's needs. In the 1940s he was responsible for the railway station at Amiens, the Atomic Centre at Saclay and, one of his last important works, the redevelopment after wartime damage of the town centre of Le Havre. For the latter, he laid out large open squares enclosed by prefabricated units, which display a certain monotony, despite the imposing town hall and Church of St Joseph in the Place de L'Hôtel de Ville.[br]Principal Honours and DistinctionsPresident des Réunions Internationales des Architectes.

64 Sprague, Frank Julian
[br]b. 25 July 1857 Milford, Connecticut, USAd. 25 October 1934 New York, USA[br]American electrical engineer and inventor, a leading innovator in electric propulsion systems for urban transport.[br]Graduating from the United States Naval Academy, Annapolis, in 1878, Sprague served at sea and with various shore establishments. In 1883 he resigned from the Navy and obtained employment with the Edison Company; but being convinced that the use of electricity for motive power was as important as that for illumination, in 1884 he founded the Sprague Electric Railway and Motor Company. Sprague began to develop reliable and efficient motors in large sizes, marketing 15 hp (11 kW) examples by 1885. He devised the method of collecting current by using a wooden, spring-loaded rod to press a roller against the underside of an overhead wire. The installation by Sprague in 1888 of a street tramway on a large scale in Richmond, Virginia, was to become the prototype of the universally adopted trolley system with overhead conductor and the beginning of commercial electric traction. Following the success of the Richmond tramway the company equipped sixty-seven other railways before its merger with Edison General Electric in 1890. The Sprague traction motor supported on the axle of electric streetcars and flexibly mounted to the bogie set a pattern that was widely adopted for many years.Encouraged by successful experiments with multiple-sheave electric elevators, the Sprague Elevator Company was formed and installed the first set of high-speed passenger cars in 1893–4. These effectively displaced hydraulic elevators in larger buildings. From experience with control systems for these, he developed his system of multiple-unit control for electric trains, which other engineers had considered impracticable. In Sprague's system, a master controller situated in the driver's cab operated electrically at a distance the contactors and reversers which controlled the motors distributed down the train. After years of experiment, Sprague's multiple-unit control was put into use for the first time in 1898 by the Chicago South Side Elevated Railway: within fifteen years multiple-unit operation was used worldwide.[br]Principal Honours and DistinctionsPresident, American Institute of Electrical Engineers 1892–3.

65 Worsdell, Nathaniel
[br]b. 10 October 1809 London, Englandd. 24 July 1886 Birkenhead, England[br]English coachbuilder and inventor.[br]Worsdell \& Son, Coachbuilders, was set up in Liverpool by Thomas Clarke Worsdell and his son Nathaniel in 1827. They were introduced to George Stephenson and built the tender for Rocket. More importantly, they designed and built for the Liverpool \& Manchester Railway coaches of a type comprising three coach bodies, of contemporary road-coach pattern, mounted together on a rail-wagon underframe. This became the prototype for the conventional, compartment railway coach. Nathaniel Worsdell subsequently became Carriage Superintendent of the Grand Junction Railway and patented the first mail-bag-exchange apparatus early in 1838. The terms he required for its use by the Post Office were too steep, however, and the first bagexchange apparatus of the type subsequently used extensively on British railways was designed later the same year by John Ramsey, a senior Post Office clerk.[br]Further ReadingJ.Marshall, 1978, A Biographical Dictionary of Railway Engineers, Newton Abbot: David \& Charles (the article on Worsdell is derived from family records).C.Hamilton Ellis, 1958, Twenty Locomotive Men, Shepperton: Ian Allan.P.J.G.Ransom, 1990, The Victorian Railway and How It Evolved, London: Heinemann.PJGR -
