Gregory's father was Professor of Mathematics at the Royal Military Academy, Woolwich.C.H. Gregory himself, after working for Robert Stephenson, was appointed Engineer to the London \& Croydon Railway in 1839. On it, at New Cross in 1841, he installed a semaphore signal derived from signalling apparatus used by the Royal Navy; two hinged semaphore arms projected either side from the top of a post, signalling to drivers of trains in each direction of travel. In horizontal position each arm signified "danger", an arm inclined at 45° meant "caution" and the vertical position, in which the arms disappeared within a slot in the post, meant "all right". Gregory's signal was the forerunner of semaphore signals adopted on railways worldwide. In 1843 Gregory invented the stirrup frame: signal arms were connected to stirrups that were pushed down by the signalman's foot in order to operate them, while the points were operated by levers. The stirrups were connected together to prevent conflicting signals from being shown. This was a predecessor of interlocking. In 1846 Gregory became Engineer to the Bristol \& Exeter Railway, where in 1848 he co-operated with W.B. Adams in the development and operation of the first self-propelled railcar. He later did civil engineering work in Italy and France, was Engineer to the Somerset Central and Dorset Central railways and became Consulting Engineer for the government railways in Ceylon (now Sri Lanka), Cape of Good Hope, Straits Settlements and Trinidad.

Samuel Downing had a formative influence on the development of engineering education in Ireland. He was educated at Kilkenny College and Trinity College, Dublin, where he took a BA in 1834. He subsequently attended courses in natural philosophy at Edinburgh, before taking up work as a railway and bridge engineer. Amongst structures on which he worked were the timber viaduct connecting Portland Island to the mainland in Dorset, England, and the curved viaduct at Coed-re-Coed on the Taff Vale Railway, Wales. In 1847 he was persuaded to return to Trinity College, Dublin, as Assistant to Sir John MacNeill, who had been appointed Professor of Engineering in the School of Engineering on its establishment in 1842. MacNeill always found it difficult to give up time on his engineering practice to spend on his teaching duties, so the addition of Downing to the staff gave a great impetus to the effectiveness of the School. When MacNeill retired from the Chair in 1852, Downing was his obvious successor and held the post until his death. For thirty years Downing devoted his engineering expertise and the energy of his warm personality to the School of Engineering and its students, of whom almost four hundred passed through the School in the years when he was responsible for it.

The son of G.W.C.Sinclair, a machine tool engineer, the young Sinclair's education was disrupted by the failure of his father's business. Aged 12 he left Boxgrove preparatory school and went through twelve more schools before leaving St George's School, Weybridge, at the age of 17. His first job was as an editorial assistant on a hobbyist's magazine, Practical Wireless, and his next as an editor at Bernard Books, writing a series of technical manuals. In 1961 he registered Sinclair Radionics and in the following year announced its first product, a micro-amplifier. This was the first of a series of miniaturized radio products that he put on the market while retaining his editorial job. In 1972 he launched the Sinclair Executive calculator, selling originally at £79.95 but later at £24.95. In 1976, the Black Watch, an electronic watch with digital light-emitting diode (LED) display, was marketed, to be followed by the TV1A, a miniature television with a 2 in. (5 cm) monochrome screen. During the latter part of this period, Sinclair Radionics was supported by investment from the UK National Enterprise Board, who appointed an outside managing director; after making a considerable loss, they closed the company in 1979. However, Sinclair Electronics had already been set up and started to market the UK's first cheap computer kit, the MK 14, which was followed by the ZX 80 and later the ZX 81. Price was kept at a minimum by the extensive use of existing components, though this was a restriction on performance. The small memory was enhanced from one kilobyte to seventeen kilobytes with the addition of a separate memory unit. In January 1985 Sinclair produced the Sinclair C5, a small three-wheeled vehicle driven by a washing-machine engine, intended as a revolutionary new form of personal transport; perceived as unsafe and impractical, it did not prove popular, and the failure of this venture resulted in a contraction of Sinclair's business activities. Later in 1985, a rival electronics company, Amstrad, paid £35,000,000 for all rights to existing Sinclair computer products.

In March 1992, the irrepressible Sinclair launched his latest brainchild, the Zike electric bicycle; a price of £499 was forecast. This machine, powered by an electric motor but with pedal assistance, had a top speed of 19 km/h (12 mph) and, on full power, would run for up to one hour. Its lightweight nickel-cadmium battery could be recharged either by a generator or by free-wheeling. Although more practical than the C5, it did not bring Sinclair success on the scale of his earlier micro-electronic products.

Sperry was born into a farming community in Cortland County. He received a rudimentary education at the local school, but an interest in mechanical devices was aroused by the agricultural machinery he saw around him. His attendance at the Normal School in Cortland provided a useful theoretical background to his practical knowledge. He emerged in 1880 with an urge to pursue invention in electrical engineering, then a new and growing branch of technology. Within two years he was able to patent and demonstrate his arc lighting system, complete with its own generator, incorporating new methods of regulating its output. The Sperry Electric Light, Motor and Car Brake Company was set up to make and market the system, but it was difficult to keep pace with electric-lighting developments such as the incandescent lamp and alternating current, and the company ceased in 1887 and was replaced by the Sperry Electric Company, which itself was taken over by the General Electric Company.

In the 1890s Sperry made useful inventions in electric mining machinery and then in electric street-or tramcars, with his patent electric brake and control system. The patents for the brake were important enough to be bought by General Electric. From 1894 to 1900 he was manufacturing electric motor cars of his own design, and in 1900 he set up a laboratory in Washington, where he pursued various electrochemical processes.

In 1896 he began to work on the practical application of the principle of the gyroscope, where Sperry achieved his most notable inventions, the first of which was the gyrostabilizer for ships. The relatively narrow-hulled steamship rolled badly in heavy seas and in 1904 Ernst Otto Schuck, a German naval engineer, and Louis Brennan in England began experiments to correct this; their work stimulated Sperry to develop his own device. In 1908 he patented the active gyrostabilizer, which acted to correct a ship's roll as soon as it started. Three years later the US Navy agreed to try it on a destroyer, the USS Worden. The successful trials of the following year led to widespread adoption. Meanwhile, in 1910, Sperry set up the Sperry Gyroscope Company to extend the application to commercial shipping.

At the same time, Sperry was working to apply the gyroscope principle to the ship's compass. The magnetic compass had worked well in wooden ships, but iron hulls and electrical machinery confused it. The great powers' race to build up their navies instigated an urgent search for a solution. In Germany, Anschütz-Kämpfe (1872–1931) in 1903 tested a form of gyrocompass and was encouraged by the authorities to demonstrate the device on the German flagship, the Deutschland. Its success led Sperry to develop his own version: fortunately for him, the US Navy preferred a home-grown product to a German one and gave Sperry all the backing he needed. A successful trial on a destroyer led to widespread acceptance in the US Navy, and Sperry was soon receiving orders from the British Admiralty and the Russian Navy.

In the rapidly developing field of aeronautics, automatic stabilization was becoming an urgent need. In 1912 Sperry began work on a gyrostabilizer for aircraft. Two years later he was able to stage a spectacular demonstration of such a device at an air show near Paris.

Sperry continued research, development and promotion in military and aviation technology almost to the last. In 1926 he sold the Sperry Gyroscope Company to enable him to devote more time to invention.

Born in a remote area and with no material advantages, Brindley followed casual rural labouring occupations until 1733, when he became apprenticed to Abraham Bennett of Macclesfield, a wheelwright and millwright. Though lacking basic education in reading and writing, he demonstrated his ability, partly through his photographic memory, to solve practical problems. This established his reputation, and after Bennett's death in 1742 he set up his own business at Leek as a millwright. His skill led to an invitation to solve the problem of mine drainage at Wet Earth Colliery, Clifton, near Manchester. He tunnelled 600 ft (183 m) through rock to provide a leat for driving a water-powered pump.

Following work done on a pump on Earl Gower's estate at Trentham, Brindley's name was suggested as the engineer for the proposed canal for which the Duke of Bridge water (Francis Egerton) had obtained an Act in 1759. The Earl and the Duke were brothers-in-law, and the agents for the two estates were, in turn, the Gilbert brothers. The canal, later known as the Bridgewater Canal, was to be constructed to carry coal from the Duke's mines at Worsley into Manchester. Brindley advised on the details of its construction and recommended that it be carried across the river Irwell at Barton by means of an aqueduct. His proposals were accepted, and under his supervision the canal was constructed on a single level and opened in 1761. Brindley had also surveyed for Earl Gower a canal from the Potteries to Liverpool to carry pottery for export, and the signal success of the Bridgewater Canal ensured that the Trent and Mersey Canal would also be built. These undertakings were the start of Brindley's career as a canal engineer, and it was largely from his concepts that the canal system of the Midlands developed, following the natural contours rather than making cuttings and constructing large embankments. His canals are thus winding navigations unlike the later straight waterways, which were much easier to traverse. He also adopted the 7 ft (2.13 m) wide lock as a ruling dimension for all engineering features. For cheapness, he formed his canal tunnels without a towpath, which led to the notorious practice of legging the boats through the tunnels.

Brindley surveyed a large number of projects and such was his reputation that virtually every proposal was submitted to him for his opinion. Included among these projects were the Staffordshire and Worcestershire, the Rochdale, the Birmingham network, the Droitwich, the Coventry and the Oxford canals. Although he was nominally in charge of each contract, much of the work was carried out by his assistants while he rushed from one undertaking to another to ensure that his orders were being carried out. He was nearly 50 when he married Anne Henshall, whose brother was also a canal engineer. His fees and salaries had made him very wealthy. He died in 1772 from a chill sustained when carrying out a survey of the Caldon Canal.
