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.

William was the second son and one of eleven children of Samuel Priestman, who had moved to Hull after retiring as a corn miller in Kirkstall, Leeds, and who in retirement had become a director of the North Eastern Railway Company. The family were strict Quakers, so William was sent to the Quaker School in Bootham, York. He left school at the age of 17 to start an engineering apprenticeship at the Humber Iron Works, but this company failed so the apprenticeship was continued with the North Eastern Railway, Gateshead. In 1869 he joined the hydraulics department of Sir William Armstrong \& Company, Newcastle upon Tyne, but after a year there his father financed him in business at a small, run down works, the Holderness Foundry, Hull. He was soon joined by his brother, Samuel, their main business being the manufacture of dredging equipment (grabs), cranes and winches. In the late 1870s William became interested in internal combustion engines. He took a sublicence to manufacture petrol engines to the patents of Eugène Etève of Paris from the British licensees, Moll and Dando. These engines operated in a similar manner to the non-compression gas engines of Lenoir. Failure to make the two-stroke version of this engine work satisfactorily forced him to pay royalties to Crossley Bros, the British licensees of the Otto four-stroke patents.

Fear of the dangers of petrol as a fuel, reflected by the associated very high insurance premiums, led William to experiment with the use of lamp oil as an engine fuel. His first of many patents was for a vaporizer. This was in 1885, well before Ackroyd Stuart. What distinguished the Priestman engine was the provision of an air pump which pressurized the fuel tank, outlets at the top and bottom of which led to a fuel atomizer injecting continuously into a vaporizing chamber heated by the exhaust gases. A spring-loaded inlet valve connected the chamber to the atmosphere, with the inlet valve proper between the chamber and the working cylinder being camoperated. A plug valve in the fuel line and a butterfly valve at the inlet to the chamber were operated, via a linkage, by the speed governor; this is believed to be the first use of this method of control. It was found that vaporization was only partly achieved, the higher fractions of the fuel condensing on the cylinder walls. A virtue was made of this as it provided vital lubrication. A starting system had to be provided, this comprising a lamp for preheating the vaporizing chamber and a hand pump for pressurizing the fuel tank.

Engines of 2–10 hp (1.5–7.5 kW) were exhibited to the press in 1886; of these, a vertical engine was installed in a tram car and one of the horizontals in a motor dray. In 1888, engines were shown publicly at the Royal Agricultural Show, while in 1890 two-cylinder vertical marine engines were introduced in sizes from 2 to 10 hp (1.5–7.5 kW), and later double-acting ones up to some 60 hp (45 kW). First, clutch and gearbox reversing was used, but reversing propellers were fitted later (Priestman patent of 1892). In the same year a factory was established in Philadelphia, USA, where engines in the range 5–20 hp (3.7–15 kW) were made. Construction was radically different from that of the previous ones, the bosses of the twin flywheels acting as crank discs with the main bearings on the outside.

On independent test in 1892, a Priestman engine achieved a full-load brake thermal efficiency of some 14 per cent, a very creditable figure for a compression ratio limited to under 3:1 by detonation problems. However, efficiency at low loads fell off seriously owing to the throttle governing, and the engines were heavy, complex and expensive compared with the competition.

Decline in sales of dredging equipment and bad debts forced the firm into insolvency in 1895 and receivers took over. A new company was formed, the brothers being excluded. However, they were able to attend board meetings, but to exert no influence. Engine activities ceased in about 1904 after over 1,000 engines had been made. It is probable that the Quaker ethics of the brothers were out of place in a business that was becoming increasingly cut-throat. William spent the rest of his long life serving others.

The sixth child of James Watt, merchant and general contractor, and Agnes Muirhead, Watt was a weak and sickly child; he was one of only two to survive childhood out of a total of eight, yet, like his father, he was to live to an age of over 80. He was educated at local schools, including Greenock Grammar School where he was an uninspired pupil. At the age of 17 he was sent to live with relatives in Glasgow and then in 1755 to London to become an apprentice to a mathematical instrument maker, John Morgan of Finch Lane, Cornhill. Less than a year later he returned to Greenock and then to Glasgow, where he was appointed mathematical instrument maker to the University and was permitted in 1757 to set up a workshop within the University grounds. In this position he came to know many of the University professors and staff, and it was thus that he became involved in work on the steam engine when in 1764 he was asked to put in working order a defective Newcomen engine model. It did not take Watt long to perceive that the great inefficiency of the Newcomen engine was due to the repeated heating and cooling of the cylinder. His idea was to drive the steam out of the cylinder and to condense it in a separate vessel. The story is told of Watt's flash of inspiration as he was walking across Glasgow Green one Sunday afternoon; the idea formed perfectly in his mind and he became anxious to get back to his workshop to construct the necessary apparatus, but this was the Sabbath and work had to wait until the morrow, so Watt forced himself to wait until the Monday morning.

Watt designed a condensing engine and was lent money for its development by Joseph Black, the Glasgow University professor who had established the concept of latent heat. In 1768 Watt went into partnership with John Roebuck, who required the steam engine for the drainage of a coal-mine that he was opening up at Bo'ness, West Lothian. In 1769, Watt took out his patent for "A New Invented Method of Lessening the Consumption of Steam and Fuel in Fire Engines". When Roebuck went bankrupt in 1772, Matthew Boulton, proprietor of the Soho Engineering Works near Birmingham, bought Roebuck's share in Watt's patent. Watt had met Boulton four years earlier at the Soho works, where power was obtained at that time by means of a water-wheel and a steam engine to pump the water back up again above the wheel. Watt moved to Birmingham in 1774, and after the patent had been extended by Parliament in 1775 he and Boulton embarked on a highly profitable partnership. While Boulton endeavoured to keep the business supplied with capital, Watt continued to refine his engine, making several improvements over the years; he was also involved frequently in legal proceedings over infringements of his patent.

In 1794 Watt and Boulton founded the new company of Boulton \& Watt, with a view to their retirement; Watt's son James and Boulton's son Matthew assumed management of the company. Watt retired in 1800, but continued to spend much of his time in the workshop he had set up in the garret of his Heathfield home; principal amongst his work after retirement was the invention of a pantograph sculpturing machine.

James Watt was hard-working, ingenious and essentially practical, but it is doubtful that he would have succeeded as he did without the business sense of his partner, Matthew Boulton. Watt coined the term "horsepower" for quantifying the output of engines, and the SI unit of power, the watt, is named in his honour.

Corliss's father was a physician and surgeon. The son was educated at Greenwich, New York, but while he showed an aptitude for mathematics and mechanics he first of all became a storekeeper and then clerk, bookkeeper, salesperson and official measurer and inspector of the cloth produced at W.Mowbray \& Son. He went to the Castleton Academy, Vermont, for three years and at the age of 21 returned to a store of his own in Greenwich. Complaints about stitching in the boots he sold led him to patent a sewing machine. He approached Fairbanks, Bancroft \& Co., Providence, Rhode Island, machine and steam engine builders, about producing his machine, but they agreed to take him on as a draughtsman providing he abandoned it. Corliss moved to Providence with his family and soon revolutionized the design and construction of steam engines. Although he started working out ideas for his engine in 1846 and completed one in 1848 for the Providence Dyeing, Bleaching and Calendering Company, it was not until March 1849 that he obtained a patent. By that time he had joined John Barstow and E.J.Nightingale to form a new company, Corliss Nightingale \& Co., to build his design of steam-engines. He used paired valves, two inlet and two exhaust, placed on opposite sides of the cylinder, which gave good thermal properties in the flow of steam. His wrist-plate operating mechanism gave quick opening and his trip mechanism allowed the governor to regulate the closure of the inlet valve, giving maximum expansion for any load. It has been claimed that Corliss should rank equally with James Watt in the development of the steam-engine. The new company bought land in Providence for a factory which was completed in 1856 when the Corliss Engine Company was incorporated. Corliss directed the business activities as well as technical improvements. He took out further patents modifying his valve gear in 1851, 1852, 1859, 1867, 1875, 1880. The business grew until well over 1,000 workers were employed. The cylindrical oscillating valve normally associated with the Corliss engine did not make its appearance until 1850 and was included in the 1859 patent. The impressive beam engine designed for the 1876 Centennial Exhibition by E. Reynolds was the product of Corliss's works. Corliss also patented gear-cutting machines, boilers, condensing apparatus and a pumping engine for waterworks. While having little interest in politics, he represented North Providence in the General Assembly of Rhode Island between 1868 and 1870.

Gooch gained experience as a pupil with several successive engineering firms, including Vulcan Foundry and Robert Stephenson \& Co. In 1837 he was engaged by I.K. Brunel, who was then building the Great Western Railway (GWR) to the broad gauge of 7 ft 1/4 in. (2.14 m), to take charge of the railway's locomotive department. He was just 21 years old. The initial locomotive stock comprised several locomotives built to such extreme specifications laid down by Brunel that they were virtually unworkable, and two 2–2–2 locomotives, North Star and Morning Star, which had been built by Robert Stephenson \& Co. but left on the builder's hands. These latter were reliable and were perpetuated. An enlarged version, the "Fire Fly" class, was designed by Gooch and built in quantity: Gooch was an early proponent of standardization. His highly successful 4–2–2 Iron Duke of 1847 became the prototype of GWR express locomotives for the next forty-five years, until the railway's last broad-gauge sections were narrowed. Meanwhile Gooch had been largely responsible for establishing Swindon Works, opened in 1843. In 1862 he designed 2–4–0 condensing tank locomotives to work the first urban underground railway, the Metropolitan Railway in London. Gooch retired in 1864 but was then instrumental in arranging for Brunel's immense steamship Great Eastern to be used to lay the first transatlantic electric telegraph cable: he was on board when the cable was successfully laid in 1866. He had been elected Member of Parliament for Cricklade (which constituency included Swindon) in 1865, and the same year he had accepted an invitation to become Chairman of the Great Western Railway Company, which was in financial difficulties; he rescued it from near bankruptcy and remained Chairman until shortly before his death. The greatest engineering work undertaken during his chairmanship was the boring of the Severn Tunnel.

Educated in Dublin, Muspratt was apprenticed at the age of 14 to a wholesale chemist and druggist, with whom he remained for three or four years. Muspratt then went in search of the Napoleonic War and found it first in Spain and finally as Second Officer on a naval vessel. Finding the life unpleasantly harsh, he left his ship off Swansea and returned to Dublin around 1814. Soon afterwards, he received an inheritance, much reduced and delayed by litigation in Chancery. He began manufacturing chemicals in a small way and from 1818 set up as a manufacturer of prussiate of potash. In 1823, Muspratt took advantage of the removal of the salt tax to establish the first plant in England for the largescale manufacture of soda by the Leblanc process. His first soda works was on the outskirts of Liverpool, but when this proved inadequate, he established a larger factory at St Helens, Lancashire, where the raw materials lay close at hand. This district has remained an important centre of the British chemical industry ever since. Although the plant was successful commercially, there were environmental problems. The equipment for condensing the hydrochloric acid gas produced were inadequate and this caused extensive damage to local vegetation, so that Muspratt had to contend with legal action lasting from 1832 to 1850. Eventually Muspratt moved his alkali manufacture to Widnes, which also became a great centre for the chemical industry.
