The son of a "coal viewer", Curr was brought up in the West Durham colliery district. In 1777 he went to the Duke of Norfolk's collieries at Sheffield, where in 1880 he was appointed Superintendent. There coal was conveyed underground in baskets on sledges: Curr replaced the wicker sledges with wheeled corves, i.e. small four-wheeled wooden wagons, running on "rail-roads" with cast-iron rails and hauled from the coal-face to the shaft bottom by horses. The rails employed hitherto had usually consisted of plates of iron, the flange being on the wheels of the wagon. Curr's new design involved flanges on the rails which guided the vehicles, the wheels of which were unflanged and could run on any hard surface. He appears to have left no precise record of the date that he did this, and surviving records have been interpreted as implying various dates between 1776 and 1787. In 1787 John Buddle paid tribute to the efficiency of the rails of Curr's type, which were first used for surface transport by Joseph Butler in 1788 at his iron furnace at Wingerworth near Chesterfield: their use was then promoted widely by Benjamin Outram, and they were adopted in many other English mines. They proved serviceable until the advent of locomotives demanded different rails.

In 1788 Curr also developed a system for drawing a full corve up a mine shaft while lowering an empty one, with guides to separate them. At the surface the corves were automatically emptied by tipplers. Four years later he was awarded a patent for using double ropes for lifting heavier loads. As the weight of the rope itself became a considerable problem with the increasing depth of the shafts, Curr invented the flat hemp rope, patented in 1798, which consisted of several small round ropes stitched together and lapped upon itself in winding. It acted as a counterbalance and led to a reduction in the time and cost of hoisting: at the beginning of a run the loaded rope began to coil upon a small diameter, gradually increasing, while the unloaded rope began to coil off a large diameter, gradually decreasing.

Curr's book The Coal Viewer (1797) is the earliest-known engineering work on railway track and it also contains the most elaborate description of a Newcomen pumping engine, at the highest state of its development. He became an acknowledged expert on construction of Newcomen-type atmospheric engines, and in 1792 he established a foundry to make parts for railways and engines.

Because of the poor financial results of the Duke of Norfolk's collieries at the end of the century, Curr was dismissed in 1801 despite numerous inventions and improvements which he had introduced. After his dismissal, six more of his patents were concerned with rope-making: the one he gained in 1813 referred to the application of flat ropes to horse-gins and perpendicular drum-shafts of steam engines. Curr also introduced the use of inclined planes, where a descending train of full corves pulled up an empty one, and he was one of the pioneers employing fixed steam engines for hauling. He may have resided in France for some time before his death.

Robert, the son of Thomas and Ada (Crooks) Stanley, helped to finance his early training at the Stevens Institute of Technology, Hoboken, New Jersey, by working as a manual training instructor at Montclair High School. After graduating in mechanical engineering from Stevens in 1899, and as a mining engineer from the Columbia School of Mines in 1901, he accepted a two-year assignment from the S.S.White Dental Company to investigate platinum-bearing alluvial deposits in British Columbia. This introduced him to the International Nickel Company (Inco), which had been established on 29 March 1902 to amalgamate the major mining companies working the newly discovered cupro-nickel deposits at Sudbury, Ontario. Ambrose Monell, President of Inco, appointed Stanley as Assistant Superintendent of its American Nickel Works at Camden, near Philadelphia, in 1903. At the beginning of 1904 Stanley was General Superintendent of the Orford Refinery at Bayonne, New Jersey, where most of the output of the Sudbury mines was treated.

Copper and nickel were separated there from the bessemerized matte by the celebrated "tops and bottoms" process introduced thirteen years previously by R.M.Thompson. It soon occurred to Stanley that such a separation was not invariably required and that, by reducing directly the mixed matte, he could obtain a natural cupronickel alloy which would be ductile, corrosion resistant, and no more expensive to produce than pure copper or nickel. His first experiment, on 30 December 1904, was completely successful. A railway wagon full of bessemerized matte, low in iron, was calcined to oxide, reduced to metal with carbon, and finally desulphurized with magnesium. Ingots cast from this alloy were successfully forged to bars which contained 68 per cent nickel, 23 per cent copper and about 1 per cent iron. The new alloy, originally named after Ambrose Monell, was soon renamed Monel to satisfy trademark requirements. A total of 300,000 ft2 (27,870 m²) of this white, corrosion-resistant alloy was used to roof the Pennsylvania Railway Station in New York, and it also found extensive applications in marine work and chemical plant. Stanley greatly increased the output of the Orford Refinery during the First World War, and shortly after becoming President of the company in 1922, he established a new Research and Development Division headed initially by A.J.Wadham and then by Paul D. Merica, who at the US Bureau of Standards had first elucidated the mechanism of age-hardening in alloys. In the mid- 1920s a nickel-ore body of unprecedented size was identified at levels between 2,000 and 3,000 ft (600 and 900 m) below the Frood Mine in Ontario. This property was owned partially by Inco and partially by the Mond Nickel Company. Efficient exploitation required the combined economic resources of both companies. They merged on 1 January 1929, when Mond became part of International Nickel. Stanley remained President of the new company until February 1949 and was Chairman from 1937 until his death.

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.

Symington was the son of the Superintendent of the Mines Company in Lanarkshire, and attended the local school. When he was 22 years old he was sent by Gilbert Meason, Manager of the Wanlockhead mines, to Edinburgh University. In 1779 he was working on the assembly of a Watt engine as an apprentice to his brother, George, and in 1786 he started experiments to modify a Watt engine in order to avoid infringing the separate condenser patent. He sought a patent for his alternative, which was paid for by Meason. He constructed a model steam road carriage which was completed in 1786; it was shown in Edinburgh by Meason, attracting interest but inadequate financial support. It had a horizontal cylinder and was non-condensing. No full-sized engine was ever built but the model secured the interest of Patrick Miller, an Edinburgh banker, who ordered an engine from Symington to drive an experimental boat, 25 ft (7.6 m) long with a dual hull, which performed satisfactorily on Dalswinton Loch in 1788. In the following year Miller ordered a larger engine for a bigger boat which was tried on the Forth \& Clyde Canal in December 1789, the component parts having been made by the Carron Company. The engine worked perfectly but had the effect of breaking the paddle wheels. These were repaired and further trials were successful but Miller lost interest and his experiments lapsed. Symington devoted himself thereafter to building stationary engines. He built other engines for mine pumping at Sanquhar and Leadhills before going further afield. In all, he built over thirty engines, about half of them being rotary. In 1800–1 he designed the engine for a boat for Lord Dundas, the Charlotte Dundas; this was apparently the first boat of that name and sailed on both the Forth and Clyde rivers. A second Charlotte Dundas with a horizontal cylinder was to follow and first sailed in January 1803 for the Forth \& Clyde Canal Company. The speed of the boat was only 2 mph (3 km/h) and much was made by its detractors of the damage said to be caused to the canal banks by its wash. Lord Dundas declined to authorize payment of outstanding accounts; Symington received little reward for his efforts. He died in the house of his son-in-law, Dr Robert Bowie, in Wapping, amidst heated controversy about the true inventor of steam navigation.
