Gresley was the son of the Rector of Netherseale, Derbyshire; he was educated at Marlborough and by the age of 13 was skilled at making sketches of locomotives. In 1893 he became a pupil of F.W. Webb at Crewe works, London \& North Western Railway, and in 1898 he moved to Horwich works, Lancashire \& Yorkshire Railway, to gain drawing-office experience under J.A.F.Aspinall, subsequently becoming Foreman of the locomotive running sheds at Blackpool. In 1900 he transferred to the carriage and wagon department, and in 1904 he had risen to become its Assistant Superintendent. In 1905 he moved to the Great Northern Railway, becoming Superintendent of its carriage and wagon department at Doncaster under H.A. Ivatt. In 1906 he designed and produced a bogie luggage van with steel underframe, teak body, elliptical roof, bowed ends and buckeye couplings: this became the prototype for East Coast main-line coaches built over the next thirty-five years. In 1911 Gresley succeeded Ivatt as Locomotive, Carriage \& Wagon Superintendent. His first locomotive was a mixed-traffic 2–6–0, his next a 2–8–0 for freight. From 1915 he worked on the design of a 4–6–2 locomotive for express passenger traffic: as with Ivatt's 4 4 2s, the trailing axle would allow the wide firebox needed for Yorkshire coal. He also devised a means by which two sets of valve gear could operate the valves on a three-cylinder locomotive and applied it for the first time on a 2–8–0 built in 1918. The system was complex, but a later simplified form was used on all subsequent Gresley three-cylinder locomotives, including his first 4–6–2 which appeared in 1922. In 1921, Gresley introduced the first British restaurant car with electric cooking facilities.

With the grouping of 1923, the Great Northern Railway was absorbed into the London \& North Eastern Railway and Gresley was appointed Chief Mechanical Engineer. More 4–6– 2s were built, the first British class of such wheel arrangement. Modifications to their valve gear, along lines developed by G.J. Churchward, reduced their coal consumption sufficiently to enable them to run non-stop between London and Edinburgh. So that enginemen might change over en route, some of the locomotives were equipped with corridor tenders from 1928. The design was steadily improved in detail, and by comparison an experimental 4–6–4 with a watertube boiler that Gresley produced in 1929 showed no overall benefit. A successful high-powered 2–8–2 was built in 1934, following the introduction of third-class sleeping cars, to haul 500-ton passenger trains between Edinburgh and Aberdeen.

In 1932 the need to meet increasing road competition had resulted in the end of a long-standing agreement between East Coast and West Coast railways, that train journeys between London and Edinburgh by either route should be scheduled to take 8 1/4 hours. Seeking to accelerate train services, Gresley studied high-speed, diesel-electric railcars in Germany and petrol-electric railcars in France. He considered them for the London \& North Eastern Railway, but a test run by a train hauled by one of his 4–6–2s in 1934, which reached 108 mph (174 km/h), suggested that a steam train could better the railcar proposals while its accommodation would be more comfortable. To celebrate the Silver Jubilee of King George V, a high-speed, streamlined train between London and Newcastle upon Tyne was proposed, the first such train in Britain. An improved 4–6–2, the A4 class, was designed with modifications to ensure free running and an ample reserve of power up hill. Its streamlined outline included a wedge-shaped front which reduced wind resistance and helped to lift the exhaust dear of the cab windows at speed. The first locomotive of the class, named Silver Link, ran at an average speed of 100 mph (161 km/h) for 43 miles (69 km), with a maximum speed of 112 1/2 mph (181 km/h), on a seven-coach test train on 27 September 1935: the locomotive went into service hauling the Silver Jubilee express single-handed (since others of the class had still to be completed) for the first three weeks, a round trip of 536 miles (863 km) daily, much of it at 90 mph (145 km/h), without any mechanical troubles at all. Coaches for the Silver Jubilee had teak-framed, steel-panelled bodies on all-steel, welded underframes; windows were double glazed; and there was a pressure ventilation/heating system. Comparable trains were introduced between London Kings Cross and Edinburgh in 1937 and to Leeds in 1938.

Gresley did not hesitate to incorporate outstanding features from elsewhere into his locomotive designs and was well aware of the work of André Chapelon in France. Four A4s built in 1938 were equipped with Kylchap twin blast-pipes and double chimneys to improve performance still further. The first of these to be completed, no. 4468, Mallard, on 3 July 1938 ran a test train at over 120 mph (193 km/h) for 2 miles (3.2 km) and momentarily achieved 126 mph (203 km/h), the world speed record for steam traction. J.Duddington was the driver and T.Bray the fireman. The use of high-speed trains came to an end with the Second World War. The A4s were then demonstrated to be powerful as well as fast: one was noted hauling a 730-ton, 22-coach train at an average speed exceeding 75 mph (120 km/h) over 30 miles (48 km). The war also halted electrification of the Manchester-Sheffield line, on the 1,500 volt DC overhead system; however, anticipating eventual resumption, Gresley had a prototype main-line Bo-Bo electric locomotive built in 1941. Sadly, Gresley died from a heart attack while still in office.

Between 1911 and 1914 Heinrich Focke and Georg Wulf built a monoplane and some years later, in 1924, they founded the Focke-Wulf company. They designed and built a variety of civil and military aircraft including the F 19Ente, a tail-first design of 1927. This canard layout was thought to be safer than conventional designs but, unfortunately, it crashed, killing Wulf. Around 1930 Focke became interested in rotary-wing aircraft, and in 1931 he set up a company with Gerd Achgelis to conduct research in this field. The Focke-Wulf company took out a licence to build Cierva autogiros. Focke designed an improved autogiro, the Fw 186, which flew in 1938; it was entered for a military competition, but it was beaten by a fixed-wing aircraft, the Fieseler Storch. In May 1935 Focke resigned from Focke-Wulf to concentrate on helicopter development with the Focke-Achgelis company. His first design was the Fa 61 helicopter, which utilized the fuselage and engine of a conventional aeroplane but instead of wings had two out-riggers, each carrying a rotor. The engine drove these rotors in opposite directions to counteract the adverse torque effect (with a single rotor the fuselage tends to rotate in the opposite direction to the rotor). Following its first flight on 26 June 1936, the Fa 61 went on to break several world records. However, it attracted more public attention when it was flown inside the huge Deutschlandhalle in Berlin by the famous female test pilot Hanna Reitsch in February 1938. Focke continued to develop his helicopter projects for the Focke-Achgelis company and produced the Fa 223 Drache in 1940. This used twin contra-rotating rotors, like the Fa 61, but could carry six people. Its production was hampered by allied bombing of the factory. During the Second World War Focke- Achgelis also produced a rotor kite which could be towed behind a U-boat to provide a flying "crow's nest", as well as designs for an advanced convertiplane (part aeroplane, part helicopter). After the war, Focke worked in France, the Netherlands and Brazil, then in 1954 he became Professor of Aeroplane and Helicopter Design at the University of Stuttgart.

After obtaining a degree in engineering, Fabre specialized in hydrodynamics. Around 1904 he developed an interest in flying and followed the progress of early French aviators such as Archdeacon, Voisin and Blériot who were experimenting with float-gliders. Fabre carried out many experiments during the following years, including airflow tests on various surfaces and hydrodynamic tests on different designs for floats. He also built a propeller-driven motor car to develop the most efficient design for a propeller. In 1909 he built his first "hydro-aeroplane", but it failed to fly. By March 1910 he built a new float plane which was very different from contemporary French aeroplanes. It was a tail-first (canard) monoplane and had unusual Warren girder spars exposed to the airstream. The engine was a conventional Gnome rotary mounted at the rear of the machine. On 28 March 1910 Fabre, who had no previous experience of flying, decided he was ready to test his hydro-aeroplane. First he made several straight runs to test the planing properties of his three floats, then he made several short hops. In the afternoon Fabre took off from the harbour at La Mède near Marseille before official witnesses: he was able to claim the first flight by a powered seaplane. His hydro-aeroplane is preserved in the Musée de l'Air et de l'Espace in Paris.

Despite several accidents, Fabre continued to improve his design and in October of 1910 Glenn Curtiss, the American designer, visited Fabre to compare notes. A year later Curtiss built the first of his many successful seaplanes. Fabre did not continue as an aircraft designer, but he went on to design and manufacture floats for other people.

Orphaned as a child, Hamilton went to work for Southern Pacific Railroad in his teens, and then worked for several other companies. In his spare time he learned mathematics and physics from a retired professor. In 1911 he joined the White Motor Company, makers of road motor vehicles in Denver, Colorado, where he had gone to recuperate from malaria. He remained there until 1922, apart from an eighteenth-month break for war service.

Upon his return from war service, Hamilton found White selling petrol-engined railbuses with mechanical transmission, based on road vehicles, to railways. He noted that they were not robust enough and that the success of petrol railcars with electric transmission, built by General Electric since 1906, was limited as they were complex to drive and maintain. In 1922 Hamilton formed, and became President of, the Electro- Motive Engineering Corporation (later Electro-Motive Corporation) to design and produce petrol-electric rail cars. Needing an engine larger than those used in road vehicles, yet lighter and faster than marine engines, he approached the Win ton Engine Company to develop a suitable engine; in addition, General Electric provided electric transmission with a simplified control system. Using these components, Hamilton arranged for his petrol-electric railcars to be built by the St Louis Car Company, with the first being completed in 1924. It was the beginning of a highly successful series. Fuel costs were lower than for steam trains and initial costs were kept down by using standardized vehicles instead of designing for individual railways. Maintenance costs were minimized because Electro-Motive kept stocks of spare parts and supplied replacement units when necessary. As more powerful, 800 hp (600 kW) railcars were produced, railways tended to use them to haul trailer vehicles, although that practice reduced the fuel saving. By the end of the decade Electro-Motive needed engines more powerful still and therefore had to use cheap fuel. Diesel engines of the period, such as those that Winton had made for some years, were too heavy in relation to their power, and too slow and sluggish for rail use. Their fuel-injection system was erratic and insufficiently robust and Hamilton concluded that a separate injector was needed for each cylinder.

In 1930 Electro-Motive Corporation and Winton were acquired by General Motors in pursuance of their aim to develop a diesel engine suitable for rail traction, with the use of unit fuel injectors; Hamilton retained his position as President. At this time, industrial depression had combined with road and air competition to undermine railway-passenger business, and Ralph Budd, President of the Chicago, Burlington \& Quincy Railroad, thought that traffic could be recovered by way of high-speed, luxury motor trains; hence the Pioneer Zephyr was built for the Burlington. This comprised a 600 hp (450 kW), lightweight, two-stroke, diesel engine developed by General Motors (model 201 A), with electric transmission, that powered a streamlined train of three articulated coaches. This train demonstrated its powers on 26 May 1934 by running non-stop from Denver to Chicago, a distance of 1,015 miles (1,635 km), in 13 hours and 6 minutes, when the fastest steam schedule was 26 hours. Hamilton and Budd were among those on board the train, and it ushered in an era of high-speed diesel trains in the USA. By then Hamilton, with General Motors backing, was planning to use the lightweight engine to power diesel-electric locomotives. Their layout was derived not from steam locomotives, but from the standard American boxcar. The power plant was mounted within the body and powered the bogies, and driver's cabs were at each end. Two 900 hp (670 kW) engines were mounted in a single car to become an 1,800 hp (l,340 kW) locomotive, which could be operated in multiple by a single driver to form a 3,600 hp (2,680 kW) locomotive. To keep costs down, standard locomotives could be mass-produced rather than needing individual designs for each railway, as with steam locomotives. Two units of this type were completed in 1935 and sent on trial throughout much of the USA. They were able to match steam locomotive performance, with considerable economies: fuel costs alone were halved and there was much less wear on the track. In the same year, Electro-Motive began manufacturing diesel-electrie locomotives at La Grange, Illinois, with design modifications: the driver was placed high up above a projecting nose, which improved visibility and provided protection in the event of collision on unguarded level crossings; six-wheeled bogies were introduced, to reduce axle loading and improve stability. The first production passenger locomotives emerged from La Grange in 1937, and by early 1939 seventy units were in service. Meanwhile, improved engines had been developed and were being made at La Grange, and late in 1939 a prototype, four-unit, 5,400 hp (4,000 kW) diesel-electric locomotive for freight trains was produced and sent out on test from coast to coast; production versions appeared late in 1940. After an interval from 1941 to 1943, when Electro-Motive produced diesel engines for military and naval use, locomotive production resumed in quantity in 1944, and within a few years diesel power replaced steam on most railways in the USA.

Hal Hamilton remained President of Electro-Motive Corporation until 1942, when it became a division of General Motors, of which he became Vice-President.

Professor Langley was a distinguished mathematician and astronomer who became Secretary of the Smithsonian Institution (US National Museum) in 1887. He was also interested in aviation and embarked on a programme of experiments with a whirling arm to test wings and with a series of free-flying models. In 1896 one of his steam-powered models made a flight of 4,199 ft (1,280 m): this led to a grant from the Government to subsidize the construction of a manned aeroplane. Langley commissioned Stephen M. Balzer, an automobile engine designer, to build a lightweight aero-engine and appointed his assistant, Charles M.Manly, to oversee the project. After many variations, including rotary and radical designs, two versions of the Balzer-Manly engine were produced, one quarter size and one full size. In August 1903 the small engine powered a model which thus became the first petrol-engined aeroplane to fly. Langley designed his full-size aeroplane (which he called an Aerodrome) with tandem wings and a cruciform tail unit. The Balzer-Manly engine drove two pusher propellers. Manly was to be the pilot as Langley was now almost 70 years old. Most early aviators tested their machines by making tentative hops, but Langley decided to launch his Aerodrome by catapult from the roof of a houseboat on the Potomac river. Two attempts were made and on both occasions the Aerodrome crashed into the river: catapult problems and perhaps a structural weakness were to blame. The second crash occurred on 8 December 1903 and it is ironic that the Wright brothers, with limited funds and no Government support, successfully achieved a manned flight just nine days later. Langley was heartbroken. After his death there followed a strange affair in 1914 when Glenn Curtiss took Langley's Aerodrome, modified it, and tried to prove that but for the faulty catapult it would have flown before the Wrights' Flyer. A brief flight was made with floats instead of the catapult, and it flew rather better after more extensive modifications and a new engine.

Otto Lilienthal and his brother Gustav developed an interest in flying as boys, when they studied birds in flight, built models and even tried to fit wings to their arms. Gustav went on to become a successful architect while Otto, after a brilliant scholastic career, became a mechanical engineer. Otto was able to devote his spare time to the problems of flight, and Gustav helped when his work allowed. They considered manpowered and mechanically powered projects, but neither looked hopeful so they turned to gliding. Otto published his research work in a book, Bird Flight as a Basis for Aviation. By 1889 Otto Lilienthal was ready to test his first full-size gliders. No. 1 and No. 2 were not successful, but No. 3, built in 1891, showed promise. He gradually improved his designs and his launching sites as he gained experience. To take off he ran downhill carrying his hang-glider until it became airborne, then he controlled it by swinging his body weight in the appropriate direction. He even built an artificial mound near Berlin so that he could take off into the wind whichever way it was blowing.

In all, Lilienthal built some eighteen gliders with various wing shapes, including biplanes. By 1895 he was planning movable control surfaces (operated by head movement) and a powered version using a carbonic acid gas motor. Unfortunately, Lilienthal crashed and died of his injuries before these ideas could be tested. In all, he made over two thousand flights covering distances up to 300 m (300 yds. Many of these flights were recorded on photographs and so generated an interest in flying. Lilienthal's achievements also encouraged other pioneers, such as Percy Pilcher in Britain, and Octave Chanute and the Wright brothers in the United States.

At the age of fifteen, Porsche built a complete electrical installation for his home. In 1894 he went to technical school in Vienna. Four years later he became Manager of the test department of the Bela Egger concern, which later became part of the Brown Boveri organization where he became the first Assistant in the calculating section. In 1899 he joined the long-established coachbuilders Jacob Lohner, and in 1902 a car of his design with mixed drive won the 1,000 kg (2,200 lb) class in the Exelberg races. In 1905 he joined the Austro-Daimler Company as Technical Director; his subsequent designs included an 85 hp mixed-drive racing car in 1907 and in 1912 an air-cooled aircraft engine which came to be known in later years as the "great-grandfather" of the Volkswagen engine. In 1916, he became Managing Director of Austro-Daimler.

In 1921 he designed his first small car, which, appearing under the name of Sasch, won its class in the 1922 Targa Florio, a gruelling road-race in Italy. In 1923 Porsche left Austro-Daimler and joined the Daimler Company in Untertürk-heim, near Stuttgart, Germany. In 1929 he joined the firm of Steyr in Austria as a director and chief engineer, and in 1930 he set up his own independent design office in Stuttgart. In 1932 he visited Russia, and in the same year completed the design calculations for the Auto-Union racing car.

In 1934, with his son Ferry (b. 1909), he prepared a plan for the construction of the German "people's car", a project initiated by Adolf Hitler and his Nazi regime; in June of that year he signed a contract for the design work on the Volkswagen. Racing cars of his design were also successful in 1934: the rear-engined Auto-Union won the German Grand Prix, and another Au to-Union car took the Flying Kilometre speed record at 327 km/h (203.2 mph). In 1935 Daimler-Benz started preproduction on the Volkswagen. The first trials of the cars took place in the autumn of 1936, and the following year thirty experimental cars were built by Daimler-Benz. In that year, Porsche visited the United States, where he met Henry Ford; in October an Auto-Union took the Flying Five Kilometre record at 404.3 km/h (251.2 mph). On 26 May 1938, the foundation stone of the Volkswagen factory was laid in Wolfsburg, near Braunschweig, Germany.

In October 1945 Ferdinand Porsche was arrested by a unit of the United States Army and taken to Hessen; the French army removed him to Baden-Baden, then to Paris and later to Dijon. During this time he was consulted by Renault engineers regarding the design of their 4CV and designed a diesel-engined tractor. He was finally released on 5 August 1947. His last major work before his death was the approval of the design for the Cisitalia Grand Prix car.

After serving an apprenticeship in the lace industry, Stringfellow left Nottingham in about 1820 and moved to Chard in Somerset, where he set up his own business. He had wide interests such as photography, politics, and the use of electricity for medical treatment. Stringfellow met William Samuel Henson, who also lived in Chard and was involved in lacemaking, and became interested in his "aerial steam carriage" of 1842–3. When support for this project foundered, Henson and Stringfellow drew up an agreement "Whereas it is intended to construct a model of an Aerial Machine". They built a large model with a wing span of 20 ft (6 m) and powered by a steam engine, which was probably the work of Stringfellow. The model was tested on a hillside near Chard, often at night to avoid publicity, but despite many attempts it never made a successful flight. At this point Henson emigrated to the United States. From 1848 Stringfellow continued to experiment with models of his own design, starting with one with a wing span of 10 ft (3m). He decided to test it in a disused lace factory, rather than in the open air. Stringfellow fitted a horizontal wire which supported the model as it gained speed prior to free flight. Unfortunately, neither this nor later models made a sustained flight, despite Stringfellow's efficient lightweight steam engine. For many years Stringfellow abandoned his aeronautical experiments, then in 1866 when the (Royal) Aeronautical Society was founded, his interest was revived. He built a steam-powered triplane, which was demonstrated "flying" along a wire at the world's first Aeronautical Exhibition, held at Crystal Palace, London, in 1868. Stringfellow also received a cash prize for one of his engines, which was the lightest practical power unit at the Exhibition. Although Stringfellow's models never achieved a really successful flight, his designs showed the way for others to follow. Several of his models are preserved in the Science Museum in London.
