Wilbur and Orville designed and built bicycles in Dayton, Ohio. In the 1890s they developed an interest in flying which led them to study the experiments of gliding pioneers such as Otto Lilienthal in Germany, and their fellow American Octave Chanute. The Wrights were very methodical and tackled the many problems stage by stage. First, they developed a method of controlling a glider using movable control surfaces, instead of weight-shifting as used in the early hand-gliders. They built a wind tunnel to test their wing sections and by 1902 they had produced a controllable glider. Next they needed a petrol engine, and when they could not find one to suit their needs they designed and built one themselves.

On 17 December 1903 their Flyer was ready and Orville made the first short flight of 12 seconds; Wilbur followed with a 59-second flight covering 853 ft (260 m). An improved design, Flyer II, followed in 1904 and made about eighty flights, including circuits and simple ma-noeuvres. In 1905 Flyer III made several long flights, including one of 38 minutes covering 24½ miles (39 km). Most of the Wrights' flying was carried out in secret to protect their patents, so their achievements received little publicity. For a period of two and a half years they did not fly, but they worked to improve their Flyer and to negotiate terms for the sale of their invention to various governments and commercial syndi-cates.

In 1908 the Wright Model A appeared, and when Wilbur demonstrated it in France he astounded the European aviators by making several flights lasting more than one hour and one of 2 hours 20 minutes. Considerable numbers of the Model A were built, but the European designers rapidly caught up and overtook the Wrights. The Wright brothers became involved in several legal battles to protect their patents: one of these, with Glenn Curtiss, went on for many years. Wilbur died of typhoid fever in 1912. Orville sold his interest in the Wright Company in 1915, but retained an interest in aeronautical research and lived on to see an aeroplane fly faster than the speed of sound.

Oswald Short trained as an engineer; he was largely self-taught but was assisted by his brothers Eustace and Horace. In 1898 Eustace and the young Oswald set up a balloon business, building their first balloon in 1901. Two years later they sold observation balloons to the Government of India, and further orders followed. Meanwhile, in 1906 Horace designed a high-altitude balloon with a spherical pressurized gondola, an idea later used by Auguste Piccard, in 1931. Horace, a strange genius with a dominating character, joined his younger brothers in 1908 to found Short Brothers. Their first design, based on the Wright Flyer, was a limited success, but No. 2 won a Daily Mail prize of £1,000. In the same year, 1909, the Wright brothers chose Shorts to build six of their new Model A biplanes. Still using the basic Wright layout, Horace designed the world's first twin-engined aeroplane to fly successfully: it had one engine forward of the pilot, and one aft. During the years before the First World War the Shorts turned to tractor biplanes and specialized in floatplanes for the Admiralty.

Oswald established a seaplane factory at Rochester, Kent, during 1913–14, and an airship works at Cardington, Bedfordshire, in 1916. Short Brothers went on to build the rigid airship R 32, which was completed in 1919. Unfortunately, Horace died in 1917, which threw a greater responsibility onto Oswald, who became the main innovator. He introduced the use of aluminium alloys combined with a smooth "stressed-skin" construction (unlike Junkers, who used corrugated skins). His sleek biplane the Silver Streak flew in 1920, well ahead of its time, but official support was not forthcoming. Oswald Short struggled on, trying to introduce his all-metal construction, especially for flying boats. He eventually succeeded with the biplane Singapore, of 1926, which had an all-metal hull. The prototype was used by Sir Alan Cobham for his flight round Africa. Several successful all-metal flying boats followed, including the Empire flying boats (1936) and the ubiquitous Sunderland (1937). The Stirling bomber (1939) was derived from the Sunderland. The company was nationalized in 1942 and Oswald Short retired the following year.

Gabriel Voisin was one of a group of aviation pioneers working in France c. 1905. One of the leaders of this group was a rich lawyer-sportsman, Ernest Archdeacon. For a number of years they had been building gliders based on those of the Wright brothers. Archdeacon's glider of 1904 was flown by Voisin, who went on to assist in the design and manufacture of gliders for Archdeacon and Louis Blériot, including successful float-gliders. Gabriel Voisin was joined by his brother Charles in 1905 and they set up the first commercial aircraft factory. As the Voisins had limited funds, they had to seek customers who could afford to indulge in the fashionable hobby of flying. One was Santos- Dumont, who commissioned Voisin to build his "14 bis" aeroplane in 1906.

Early in 1907 the Voisins built their first powered aeroplane, but it was not a success.

Later that year they completed a biplane for a Paris sculptor, Léon Delagrange, and another for Henri Farman. The basic Voisin was a biplane with the engine behind the pilot and a "pusher" propeller. Pitching was controlled by biplane elevators forward of the pilot and rudders were fitted to the box kite tail, but there was no control of roll.

Improvements were gradually introduced by the Voisins and their customers, such as Farman. Incidentally, to flatter their clients the Voisins often named the aircraft after them, thus causing some confusion to historians. Many Voisins were built up until 1910, when the company's fortunes sank. Competition was growing, the factory was flooded, and Charles left. Gabriel started again, building robust biplanes of steel construction. Voisin bombers were widely used during the First World War, and a subsidiary factory was built in Russia.

In August 1917, Voisin sold his business when the French Air Ministry decided that Voisin aeroplanes were obsolete and that the factory should be turned over to the building of engines. After the war he started another business making prefabricated houses, and then turned to manufacturing motor cars. From 1919 to 1939 his company produced various models, mainly for the luxury end of the market but also including a few sports and racing cars. In the early 1950s he designed a small two-seater, which was built by the Biscuter company in Spain. The Voisin company finally closed in 1958.

He was the son of an Irish immigrant farmer, William Ford, and the oldest son to survive of Mary Litogot; his mother died in 1876 with the birth of her sixth child. He went to the village school, and at the age of 16 he was apprenticed to Flower brothers' machine shop and then at the Drydock \& Engineering Works in Detroit. In 1882 he left to return to the family farm and spent some time working with a 1 1/2 hp steam engine doing odd jobs for the farming community at $3 per day. He was then employed as a demonstrator for Westinghouse steam engines. He met Clara Jane Bryant at New Year 1885 and they were married on 11 April 1888. Their only child, Edsel Bryant Ford, was born on 6 November 1893.

At that time Henry worked on steam engine repairs for the Edison Illuminating Company, where he became Chief Engineer. He became one of a group working to develop a "horseless carriage" in 1896 and in June completed his first vehicle, a "quadri cycle" with a two-cylinder engine. It was built in a brick shed, which had to be partially demolished to get the carriage out.

Ford became involved in motor racing, at which he was more successful than he was in starting a car-manufacturing company. Several early ventures failed, until the Ford Motor Company of 1903. By October 1908 they had started with production of the Model T. The first, of which over 15 million were built up to the end of its production in May 1927, came out with bought-out steel stampings and a planetary gearbox, and had a one-piece four-cylinder block with a bolt-on head. This was one of the most successful models built by Ford or any other motor manufacturer in the life of the motor car.

Interchangeability of components was an important element in Ford's philosophy. Ford was a pioneer in the use of vanadium steel for engine components. He adopted the principles of Frederick Taylor, the pioneer of time-and-motion study, and installed the world's first moving assembly line for the production of magnetos, started in 1913. He installed blast furnaces at the factory to make his own steel, and he also promoted research and the cultivation of the soya bean, from which a plastic was derived.

In October 1913 he introduced the "Five Dollar Day", almost doubling the normal rate of pay. This was a profit-sharing scheme for his employees and contained an element of a reward for good behaviour. About this time he initiated work on an agricultural tractor, the "Fordson" made by a separate company, the directors of which were Henry and his son Edsel.

In 1915 he chartered the Oscar II, a "peace ship", and with fifty-five delegates sailed for Europe a week before Christmas, docking at Oslo. Their objective was to appeal to all European Heads of State to stop the war. He had hoped to persuade manufacturers to replace armaments with tractors in their production programmes. In the event, Ford took to his bed in the hotel with a chill, stayed there for five days and then sailed for New York and home. He did, however, continue to finance the peace activists who remained in Europe. Back in America, he stood for election to the US Senate but was defeated. He was probably the father of John Dahlinger, illegitimate son of Evangeline Dahlinger, a stenographer employed by the firm and on whom he lavished gifts of cars, clothes and properties. He became the owner of a weekly newspaper, the Dearborn Independent, which became the medium for the expression of many of his more unorthodox ideas. He was involved in a lawsuit with the Chicago Tribune in 1919, during which he was cross-examined on his knowledge of American history: he is reputed to have said "History is bunk". What he actually said was, "History is bunk as it is taught in schools", a very different comment. The lawyers who thus made a fool of him would have been surprised if they could have foreseen the force and energy that their actions were to release. For years Ford employed a team of specialists to scour America and Europe for furniture, artefacts and relics of all kinds, illustrating various aspects of history. Starting with the Wayside Inn from South Sudbury, Massachusetts, buildings were bought, dismantled and moved, to be reconstructed in Greenfield Village, near Dearborn. The courthouse where Abraham Lincoln had practised law and the Ohio bicycle shop where the Wright brothers built their first primitive aeroplane were added to the farmhouse where the proprietor, Henry Ford, had been born. Replicas were made of Independence Hall, Congress Hall and the old City Hall in Philadelphia, and even a reconstruction of Edison's Menlo Park laboratory was installed. The Henry Ford museum was officially opened on 21 October 1929, on the fiftieth anniversary of Edison's invention of the incandescent bulb, but it continued to be a primary preoccupation of the great American car maker until his death.

Henry Ford was also responsible for a number of aeronautical developments at the Ford Airport at Dearborn. He introduced the first use of radio to guide a commercial aircraft, the first regular airmail service in the United States. He also manufactured the country's first all-metal multi-engined plane, the Ford Tri-Motor.

Edsel became President of the Ford Motor Company on his father's resignation from that position on 30 December 1918. Following the end of production in May 1927 of the Model T, the replacement Model A was not in production for another six months. During this period Henry Ford, though officially retired from the presidency of the company, repeatedly interfered and countermanded the orders of his son, ostensibly the man in charge. Edsel, who died of stomach cancer at his home at Grosse Point, Detroit, on 26 May 1943, was the father of Henry Ford II. Henry Ford died at his home, "Fair Lane", four years after his son's death.

The Breguet family had been manufacturing fine clocks since before the French Revolution, but Louis Breguet and his brother Jacques used their mechanical skills to produce a helicopter, or "gyroplane" as they named it. It was a complex machine with four biplane rotors (i.e. thirty-two lifting surfaces). Louis Breguet had carried out many tests to determine the most suitable rotor design. The Breguet brothers were assisted by Professor Charles Richet and the Breguet-Richet No. 1 was tested in September 1907 when it succeeded in lifting itself, and its pilot, to a height of 1.5 metres. Unfortunately, the gyroplane was rather unstable and four helpers had to steady it; consequently, the flight did not qualify as a "free" flight. This was achieved two months later, also in France, by Paul Cornu who made a 20-second free flight.

Louis Breguet turned his attention to aeroplane design and produced a tractor biplane when most other biplanes followed the Wright brothers' layout with a forward elevator and pusher propeller. The Breguet I made quite an impression at the 1909 Reims meeting, but the Breguet IV created a world record the following year by carrying six people. During the First World War the Breguet Type 14 bomber was widely used by French and American squadrons. Between the First and Second World Wars a wide variety of designs were produced, including flying boats and another helicopter, the Breguet- Dorand Gyroplane which flew for over one hour in 1936. The Breguet company survived World War II and in the late 1940s developed a successful four-engined airliner/transport, the Deux-Ponts, which had a bulbous double-deck fuselage.

Breguet was an innovative designer, although his designs were functional rather than elegant. He was an early advocate of metal construction and developed an oleo- (oil-spring) undercarriage leg.

Curtiss started his career in the bicycle business, then became a designer of motor-cycle engines, and in 1904 he designed and built an airship engine. The success of his engine led to him joining the Aerial Experimental Association (AEA), founded by the inventor Alexander Graham Bell. Working with the AEA, Curtiss built several engines and designed a biplane, June Bug, in which he won a prize for the first recorded flight of over 1 km (1,100yd) in the USA. In 1909 Curtiss joined forces with Augustus M.Herring, who had earlier flown Octave Chanute's gliders, to form the Herring-Curtiss Company. Their Gold Bug was a success and led to the Golden Flyer, in which Glenn Curtiss won the Gordon Bennett Cup at Rheims in France with a speed of 75.7 km/h (47 mph). At this time the Wright brothers accused Curtiss and the new Curtiss Aeroplane Company of infringing their patent rights, and a bitter lawsuit ensued. The acrimony subsided during the First World War and in 1929 the two companies merged to form the Curtiss-Wright Corporation.

Curtiss had started experimenting with water-based aircraft in 1908, but it was not until 1911 that he managed to produce a successful float-plane. He then co-operated with the US Navy in developing catapults to launch aircraft from ships at sea. During the First World War, Curtiss produced the JN-4 Jenny trainer, which became probably his best-known design. This sturdy bi-plane continued in service long after the war and was extensively used by "barnstorming" pilots at air shows and for early mail flights. In 1919 a Navy-Curtiss NC-4 flying boat achieved the first flight across the Atlantic, having made the crossing in stages, refuelling en route. Curtiss himself, however, had little interest in aviation in his later years and turned his attention to real-estate development in Florida.

A.V.Roe served an apprenticeship at a railway works, studied marine engineering at Kings College London, served at sea as an engineer, and then took a job in the motor-car industry. His hobby was flying: after studying bird-flight, he built several flying models and in 1907 one of these won a prize offered by the Daily Mail. With the prize money he built a full-size aeroplane loosely based on the Flyer of the Wright brothers, with whom he had corresponded. In September, Roe took his biplane to the motorracing circuit at Brooklands, in Surrey, but it made only a few hops and his activities were not welcomed. Roe then moved to Essex, where he assembled his new aeroplane under the arch of a railway bridge. This was a triplane design with the engine at the front (a "tractor"), and during 1909 it made several flights (this triplane is preserved by the Science Museum in London).

In 1910 Roe and his brother Humphrey founded A.V.Roe \& Co. in Manchester, they described it the "Aviator's Storehouse". During the next three years Roe designed and built aeroplanes in Manchester, then transported them to Brooklands to fly (the authorities now made him more welcome). One of the most significant of these was his Type D tractor biplane of 1911, which led to the Avro 504 two-seater trainer of 1913. This was one of the most successful trainers of all time, as around 10,000 were built. In November 1914 a flight of Avro 504s carried out the first-ever bombing raid when they attacked German airship sheds as Friedrichshafen. A.V.Roe produced the first aeroplanes with enclosed cabins during 1912: the Type F monoplane and Type G biplane. After the war, his Avian was used for several record-breaking flights. In 1928 he sold his interest in the company bearing his name and joined forces with Saunders Ltd of Cowes, on the Isle of Wight, to found Saunders-Roe Ltd. "Saro" produced a series of flying boats, from the four-seat Cutty Sark of 1929 to the large, and ill-fated, Princess of 1952.
