Howden was educated in Prestonpans. While aged only 14 or 15, he travelled across Scotland by canal to Glasgow, where he served an engineering apprenticeship with James Gray \& Co. In 1853 he completed his time and for some months served with the civil engineers Bell and Miller, and then with Robert Griffiths, a designer of screw propellers for ships. In 1854, at the age of 22, Howden set up as a consulting engineer and designer. He designed a rivet-making machine from which he realized a fair sum by the sale of patent rights, this assisting him in converting the design business into a manufacturing one. His first contract for a marine engine came in 1859 for the compound steam engine and the watertube boilers of the Anchor Liner Ailsa Craig. This ship operated at 100 psi (approximately 7 kg/cm²), well above the norm for those days. James Howden \& Co. was formed in 1862. Despite operating in the world's most competitive market, the new company remained prosperous through the flow of inventions in marine propulsion. Shipbuilding was added to the company's list of services, but such work was subcontracted. Work was obtained from all the great shipping companies building in the Glasgow region, and with such throughput Howden's could afford research and experimentation. This led to the Howden hot-air forced-draught system, whereby furnace waste gases were used to heat the air being drawn into the combustion chambers. The first installation was on the New York City, built in 1885 for West Indian service. Howden's fertile mind brought about a fully enclosed high-speed marine steam engine in the 1900s and, shortly after, the Howden-Zoelly impulse steam turbine for land operation. Until his death, Howden worked on many technical and business problems: he was involved in the St Helena Whaling Company, marble quarrying in Greece and in the design of a recoilless gun for the Admiralty.

Huygens was born into a cultured and privileged class. His father, Constantijn, was a poet and statesman who had wide interests. Constantijn exerted a strong influence on his son, who was educated at home until he reached the age of 16. Christiaan studied law and mathematics at Ley den University from 1645 to 1647, and continued his studies at the Collegium Arausiacum in Breda until 1649. He then lived at The Hague, where he had the means to devote his time entirely to study. In 1666 he became a Member of the Académie des Sciences in Paris and settled there until his return to The Hague in 1681. He also had a close relationship with the Royal Society and visited London on three occasions, meeting Newton on his last visit in 1689. Huygens had a wide range of interests and made significant contributions in mathematics, astronomy, optics and mechanics. He also made technical advances in optical instruments and horology.

Despite the efforts of Burgi there had been no significant improvement in the performance of ordinary clocks and watches from their inception to Huygens's time, as they were controlled by foliots or balances which had no natural period of oscillation. The pendulum appeared to offer a means of improvement as it had a natural period of oscillation that was almost independent of amplitude. Galileo Galilei had already pioneered the use of a freely suspended pendulum for timing events, but it was by no means obvious how it could be kept swinging and used to control a clock. Towards the end of his life Galileo described such a. mechanism to his son Vincenzio, who constructed a model after his father's death, although it was not completed when he himself died in 1642. This model appears to have been copied in Italy, but it had little influence on horology, partly because of the circumstances in which it was produced and possibly also because it differed radically from clocks of that period. The crucial event occurred on Christmas Day 1656 when Huygens, quite independently, succeeded in adapting an existing spring-driven table clock so that it was not only controlled by a pendulum but also kept it swinging. In the following year he was granted a privilege or patent for this clock, and several were made by the clockmaker Salomon Coster of The Hague. The use of the pendulum produced a dramatic improvement in timekeeping, reducing the daily error from minutes to seconds, but Huygens was aware that the pendulum was not truly isochronous. This error was magnified by the use of the existing verge escapement, which made the pendulum swing through a large arc. He overcame this defect very elegantly by fitting cheeks at the pendulum suspension point, progressively reducing the effective length of the pendulum as the amplitude increased. Initially the cheeks were shaped empirically, but he was later able to show that they should have a cycloidal shape. The cheeks were not adopted universally because they introduced other defects, and the problem was eventually solved more prosaically by way of new escapements which reduced the swing of the pendulum. Huygens's clocks had another innovatory feature: maintaining power, which kept the clock going while it was being wound.

Pendulums could not be used for portable timepieces, which continued to use balances despite their deficiencies. Robert Hooke was probably the first to apply a spring to the balance, but his efforts were not successful. From his work on the pendulum Huygens was well aware of the conditions necessary for isochronism in a vibrating system, and in January 1675, with a flash of inspiration, he realized that this could be achieved by controlling the oscillations of the balance with a spiral spring, an arrangement that is still used in mechanical watches. The first model was made for Huygens in Paris by the clockmaker Isaac Thuret, who attempted to appropriate the invention and patent it himself. Huygens had for many years been trying unsuccessfully to adapt the pendulum clock for use at sea (in order to determine longitude), and he hoped that a balance-spring timekeeper might be better suited for this purpose. However, he was disillusioned as its timekeeping proved to be much more susceptible to changes in temperature than that of the pendulum clock.

The son of the millwright James Meikle, who is credited with the introduction of the winnowing machine into Britain, Andrew Meikle followed in his father's footsteps. His inventive inclinations were first turned to developing his father's idea, and together with his own son George he built and patented a double-fan winnowing machine.

However, in the history of agricultural development Andrew Meikle is most famous for his invention of the threshing machine, patented in 1784. He had been presented with a model of a threshing mill designed by a Mr Ilderton of Northumberland, but after failing to make a full-scale machine work, he developed the concept further. He eventually built the first working threshing machine for a farmer called Stein at Kilbagio. The patent revolutionized farming practice because it displaced the back-breaking and soul-destroying labour of flailing the grain from the straw. The invention was of great value in Scotland and in northern England when the land was becoming underpopulated as a result of heavy industrialization, but it was bitterly opposed in the south of England until well into the nineteenth century. Although the introduction of the threshing machine led to the "Captain Swing" riots of the 1830s, in opposition to it, it shortly became universal.

Meikle's provisional patent in 1785 was a natural progression of earlier attempts by other millwrights to produce such a machine. The published patent is based on power provided by a horse engine, but these threshing machines were often driven by water-wheels or even by windmills. The corn stalks were introduced into the machine where they were fed between cast-iron rollers moving quite fast against each other to beat the grain out of the ears. The power source, whether animal, water or wind, had to cause the rollers to rotate at high speed to knock the grain out of the ears. While Meikle's machine was at first designed as a fixed barn machine powered by a water-wheel or by a horse wheel, later threshing machines became mobile and were part of the rig of an agricultural contractor.

In 1788 Meikle was awarded a patent for the invention of shuttered sails for windmills. This patent is part of the general description of the threshing machine, and whilst it was a practical application, it was superseded by the work of Thomas Cubitt.

At the turn of the century Meikle became a manufacturer of threshing machines, building appliances that combined the threshing and winnowing principles as well as the reciprocating "straw walkers" found in subsequent threshing machines and in conventional combine harvesters to the present day. However, he made little financial gain from his invention, and a public subscription organized by the President of the Board of Agriculture, Sir John Sinclair, raised £1,500 to support him towards the end of his life.

Mylne was the eldest son of Thomas Mylne, Surveyor to the City of Edinburgh. Little is known of his early education. In 1754, at the age of 21, he left Edinburgh by sea and journeyed to Rome, where he attended the Academy of St Luke. There he received the first prize for architecture. In 1759 he left Rome to travel back to England, where he arrived in time for the competition then going ahead for the design and building of a new bridge across the Thames at Blackfriars. Against 68 other competitors, Mylne won the competition; the work took some ten years to complete.

In 1760 he was appointed Engineer and Architect to the City of London, and in 1767 Joint Engineer to the New River Company together with Henry Mill, who died within a few years to leave Mylne to become Chief Engineer in 1770. Thus for the next forty years he was in charge of all the works for the New River Company between Clerkenwell and Ware, the opposite ends of London's main water supply. By 1767 he had also been appointed to a number of other important posts, which included Surveyor to Canterbury Cathedral and St Paul's Cathedral. In addition to undertaking his responsibilities for these great public buildings, he designed many private houses and villas all over the country, including several buildings for the Duke of Argyll on the Inverary Castle estate.

Mylne was also responsible for the design of a great number of bridges, waterworks and other civil engineering works throughout Britain. Called in to advise on the Norwich city waterworks, he fell out with Joseph Bramah in a somewhat spectacular dispute.

For much of his life Mylne lived at the Water House at the New River Head at Islington, from which he could direct much of the work on that waterway that came under his supervision. He also had residences in New Bridge Street and, as Clerk of Works, at Greenwich Hospital. Towards the end of his life he built himself a small house at Amwell, a country retreat at the outer end of the New River. He kept a diary from 1762 to 1810 which includes only brief memoranda but which shows a remarkable diligence in travelling all over the country by stagecoach and by postchaise. He was a freemason, as were many of his family; he married Mary Home on 10 September 1770, with whom he had ten children, four of whom survived into adulthood.

Although primarily an engineer, William Pole was a man of many and varied talents, being amongst other things an accomplished musician (his doctorate was in music) and an authority on whist. He served an apprenticeship at the Horsley Company in Birmingham, and moved to London in 1836, when he was employed first as Manager to a gasworks. In 1844 he published a study of the Cornish pumping engine, and he also accepted an appointment as the first Professor of Engineering in the Elphinstone College at Bombay. He spent three pioneering years in this post, and undertook the survey work for the Great Indian Peninsular Railway. Before returning to London in 1848 he married Matilda Gauntlett, the daughter of a clergyman.

Back in Britain, Pole was employed by James Simpson, J.M.Rendel and Robert Stephenson, the latter engaging him to assist with calculations on the Britannia Bridge. In 1858 he set up his own practice. He kept a very small office, choosing not to delegate work to subordinates but taking on a bewildering variety of commissions for government and private companies. In the first category, he made calculations for government officials of the main drainage of the metropolis and for its water supply. He lectured on engineering to the Royal Engineers' institution at Chatham, and served on a Select Committee to enquire into the armour of warships and fortifications. He became a member of the Royal Commission on the Railways of Great Britain and Ireland (the Devonshire Commission, 1867) and reported to the War Office on the MartiniHenry rifle. He also advised the India Office about examinations for engineering students. The drafting and writing up of reports was frequently left to Pole, who also made distinguished contributions to the official Lives of Robert Stephenson (1864), I.K. Brunel (1870) and William Fairbairn (1877). For other bodies, he acted as Consulting Engineer in England to the Japanese government, and he assisted W.H.Barlow in calculations for a bridge at Queensferry on the Firth of Forth (1873). He was consulted about many urban water supplies.

Pole joined the Institution of Civil Engineers as an Associate in 1840 and became a Member in 1856. He became a Member of Council, Honorary Secretary (succeeding Manby in 1885–96) and Honorary Member of the Institution. He was interested in astronomy and photography, he was fluent in several languages, was an expert on music, and became the world authority on whist. In 1859 he was appointed Professor of Civil Engineering at University College London, serving in this office until 1867. Pole, whose dates coincided closely with those of Queen Victoria, was one of the great Victorian engineers: he was a polymath, able to apply his great abilities to an amazing range of different tasks. In engineering history, he deserves to be remembered as an outstanding communicator and popularizer.

The son of Caleb and Sally Pratt, Thomas Pratt attended public school in Boston before going on to the Rensselaer School (now the Rensselaer Polytechnic Institute) in Troy, New York. While at school, his spare time was spent assisting his father, a well-known architect, in his practice. He is said to have drawn a complete set of plans for a substantial house when only 12 years old. At the conclusion of his studies, he was offered a teaching position at Rensselaer but turned it down as he was planning an engineering career; he became a government assistant on the construction of dry docks at Charleston, South Carolina, and Norfolk, Virginia.

After this experience of government work, he turned to railroad construction, first with the Boston and Lowell and Boston and Maine railroads, followed by many others. In this work, he became involved in bridge construction, mostly as consulting engineer. His best-known bridge was that over the Merrimack River at Newburyport, Massachusetts, which he built with six long timber spans and a metal drawspan. He also invented a new method of ship propulsion, a form of steam boiler, an equalizer for drawbridge supports and an improved form of combined timber and steel truss; he is best known, however, for the Pratt truss. This did not truly come into its own until the inception of all-metal construction for bridges, by which time it was too late for Pratt to gain much financial reward from it.

At the conclusion of his schooling in the South of England, Yarrow became an indentured apprentice to the Thames engine-builder Ravenhill. During this five-year period various incidents and meetings sharpened his interest in scientific matters and he showed the skills that in later years were to be so beneficial to shipbuilding. For two years he acted as London representative for Ravenhill before joining up with a Mr Hedley to form a shipyard on the Isle of Dogs. The company lasted from 1868 until 1875 and in that period produced 350 small launches and other craft. This massive output enabled Yarrow to gain confidence in many aspects of ship design. Within two years of setting out on his own he built his first ship for the Royal Navy: a torpedo boat, then at the cutting edge of technology.

In the early 1890s the company was building watertube boilers and producing destroyers with speeds in excess of 27 knots (50 km/h); it built the Russian destroyer Sokol, did pioneering work with aluminium and with high-tensile steels and worked on shipboard equipment to nullify vibrational effects. With the closure of most of the Thames shipyards and the run-down in skilled labour, Yarrow decided that the shipyard must move to some other part of the United Kingdom. After careful deliberation a green field site to the west of Glasgow was chosen, and in 1908 their first Clyde-built destroyer was launched. The company expanded, more building berths were arranged, boiler construction was developed and over the years they became recognized as specialists in smaller highspeed craft and in "knock down" ships for other parts of the world.

Yarrow retired in 1913, but at the commencement of the First World War he returned to help the yard produce, in four years, twenty-nine destroyers with speeds of up to 40 knots (74 km/h). At the end of hostilities he gave of his time and money to many charities, including those for ex-servicemen. He left a remarkable industrial organization which remains to this day the most prolific builder of surface craft for the Royal Navy.
