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.

After being educated at Sheffield Grammar School, Thompson and his elder brother established Aberdare Iron Works, South Wales, where he gained experience in mine engineering from the coal-and ironstone-mines with which the works were connected. In 1811 he moved to the North of England as Managing Partner in Bewicke's Main Colliery, County Durham, which was replaced in 1814 by a new colliery at nearby Ouston. Coal from this was carried to the Tyne over the Pelew Main Wagonway, which included a 1,992 yd (1,821 m) section where horses had to haul loaded wagons between the top of one cable-worked incline and the foot of the next. Both inclines were worked by stationary steam engines, and by installing a rope with a record length of nearly 1 1/2 miles (2.4 km), in 1821 Thompson arranged for the engine of the upper incline to haul the loaded wagons along the intervening section also. To their rear was attached the rope from the engine of the lower incline, to be used in due course to haul the empties back again.

He subsequently installed this system of "reciprocal working" elsewhere, in particular in 1826 over five miles (8 km) of the Brunton \& Shields Railroad, a colliery line north of the Tyne, where trains were hauled at an average speed of 6 mph (10 km/h) including rope changes. This performance was better than that of contemporary locomotives. The directors of the Liverpool \& Manchester Railway, which was then being built, considered installing reciprocal cable haulage on their line, and then decided to stage a competition to establish whether an improved steam locomotive could do better still. This competition became the Rainhill Trials of 1829 and was decisively won by Rocket, which had been built for the purpose.

Thompson meanwhile had become prominent in the promotion of the Newcastle \& Carlisle Railway, which, when it received its Act in 1829, was the longest railway so far authorized in Britain.

Menzies was admitted as a member of the Faculty of Advocates on 31 January 1719. It is evident from his applications for patents that he was more concerned with inventions than the law, however. He took out his first patent in 1734 for a threshing machine in which a number of flails were attached to a horizontal axis, which was moved rapidly forwards and backwards through half a revolution, essentially imitating the action of an ordinary flail. The grain to be threshed was placed on either side.

Though not a practical success, Menzies's invention seems to have been the first for the mechanical threshing of grain. His idea of imitating non-mechanized action also influenced his invention of a coal cutter, for which he took out a patent in 1761 and which copied miners' tools for obtaining coal. He proposed to carry heavy chains down the pit so that they could be used to give motion to iron picks, saws or other chains with cutting implements. The chains could be set into motion by a steam-engine, by water-or windmills, or by horses gins. Although it is quite obvious that this apparatus could not work, Menzies was the first to have thought of mechanizing coal production in the style that was in use in the late twentieth century. Subsequent to Menzies's proposal, many inventors at varying intervals followed this direction until the problem was finally solved one century later by, among others, W.E. Garforth.

Menzies had successfully used the power of a steam-engine on the Wear eight years beforehand, when he obtained a patent for raising coal. According to his device a descending bucket filled with water raised a basket of coals, while a steam-engine pumped the water back to the surface; the balance-tub system, in various forms, quickly spread to other coalfields. Menzies's patent from 1750 for improved methods of carrying the coals from the coalface to the pit-shaft had also been of considerable influence: this device employed self-acting inclined planes, whereon the descending loaded wagons hauled up the empty ones.

The Wylam wagonway passed Newburn, and Hedley, who went to school at Wylam, must have been familiar with this wagonway from childhood. It had been built c.1748 to carry coal from Wylam Colliery to the navigable limit of the Tyne at Lemington. In 1805 Hedley was appointed viewer, or manager, of Wylam Colliery by Christopher Blackett, who had inherited the colliery and wagonway in 1800. Unlike most Tyneside wagonways, the gradient of the Wylam line was insufficient for loaded wagons to run down by gravity and they had to be hauled by horses. Blackett had a locomotive, of the type designed by Richard Trevithick, built at Gateshead as early as 1804 but did not take delivery, probably because his wooden track was not strong enough. In 1808 Blackett and Hedley relaid the wagonway with plate rails of the type promoted by Benjamin Outram, and in 1812, following successful introduction of locomotives at Middleton by John Blenkinsop, Blackett asked Hedley to investigate the feasibility of locomotives at Wylam. The expense of re-laying with rack rails was unwelcome, and Hedley experimented to find out the relationship between the weight of a locomotive and the load it could move relying on its adhesion weight alone. He used first a model test carriage, which survives at the Science Museum, London, and then used a full-sized test carriage laden with weights in varying quantities and propelled by men turning handles. Having apparently satisfied himself on this point, he had a locomotive incorporating the frames and wheels of the test carriage built. The work was done at Wylam by Thomas Waters, who was familiar with the 1804 locomotive, Timothy Hackworth, foreman smith, and Jonathan Forster, enginewright. This locomotive, with cast-iron boiler and single cylinder, was unsatisfactory: Hackworth and Forster then built another locomotive to Hedley's design, with a wrought-iron return-tube boiler, two vertical external cylinders and drive via overhead beams through pinions to the two axles. This locomotive probably came into use in the spring of 1814: it performed well and further examples of the type were built. Their axle loading, however, was too great for the track and from about 1815 each locomotive was mounted on two four-wheeled bogies, the bogie having recently been invented by William Chapman. Hedley eventually left Wylam in 1827 to devote himself to other colliery interests. He supported the construction of the Clarence Railway, opened in 1833, and sent his coal over it in trains hauled by his own locomotives. Two of his Wylam locomotives survive— Puffing Billy at the Science Museum, London, and Wylam Dilly at the Royal Museum of Scotland, Edinburgh—though how much of these is original and how much dates from the period 1827–32, when the Wylam line was re-laid with edge rails and the locomotives reverted to four wheels (with flanges), is a matter of mild controversy.

Born Carl Wilhelm, he attended craft schools in Lübeck and Magdeburg, followed by an intensive course in natural science at Göttingen as a pupil of Weber. At the age of 19 Siemens travelled to England and sold an electroplating process developed by his brother Werner Siemens to Richard Elkington, who was already established in the plating business. From 1843 to 1844 he obtained practical experience in the Magdeburg works of Count Stolburg. He settled in England in 1844 and later assumed British nationality, but maintained close contact with his brother Werner, who in 1847 had co-founded the firm Siemens \& Halske in Berlin to manufacture telegraphic equipment. William began to develop his regenerative principle of waste-heat recovery and in 1856 his brother Frederick (1826–1904) took out a British patent for heat regeneration, by which hot waste gases were passed through a honeycomb of fire-bricks. When they became hot, the gases were switched to a second mass of fire-bricks and incoming air and fuel gas were led through the hot bricks. By alternating the two gas flows, high temperatures could be reached and considerable fuel economies achieved. By 1861 the two brothers had incorporated producer gas fuel, made by gasifying low-grade coal.

Heat regeneration was first applied in ironmaking by Cowper in 1857 for heating the air blast in blast furnaces. The first regenerative furnace was set up in Birmingham in 1860 for glassmaking. The first such furnace for making steel was developed in France by Pierre Martin and his father, Emile, in 1863. Siemens found British steelmakers reluctant to adopt the principle so in 1866 he rented a small works in Birmingham to develop his open-hearth steelmaking furnace, which he patented the following year. The process gradually made headway; as well as achieving high temperatures and saving fuel, it was slower than Bessemer's process, permitting greater control over the content of the steel. By 1900 the tonnage of open-hearth steel exceeded that produced by the Bessemer process.

In 1872 Siemens played a major part in founding the Society of Telegraph Engineers (from which the Institution of Electrical Engineers evolved), serving as its first President. He became President for the second time in 1878. He built a cable works at Charlton, London, where the cable could be loaded directly into the holds of ships moored on the Thames. In 1873, together with William Froude, a British shipbuilder, he designed the Faraday, the first specialized vessel for Atlantic cable laying. The successful laying of a cable from Europe to the United States was completed in 1875, and a further five transatlantic cables were laid by the Faraday over the following decade.

The Siemens factory in Charlton also supplied equipment for some of the earliest electric-lighting installations in London, including the British Museum in 1879 and the Savoy Theatre in 1882, the first theatre in Britain to be fully illuminated by electricity. The pioneer electric-tramway system of 1883 at Portrush, Northern Ireland, was an opportunity for the Siemens company to demonstrate its equipment.
