Joshua Field was educated at a boarding school in Essex until the age of 16, when he obtained employment at the Royal Dockyards at Portsmouth under the Chief Mechanical Superintendent, Simon Goodrich (1773–1847), and later in the drawing office at the Admiralty in Whitehall. At this time, machinery for the manufacture of ships' blocks was being made for the Admiralty by Henry Maudslay, who was in need of a competent draughtsman, and Goodrich recommended Joshua Field. This was the beginning of Field's long association with Maudslay; he later became a partner in the firm which was for many years known as Maudslay, Sons \& Field. They undertook a variety of mechanical engineering work but were renowned for marine steam engines, with Field being responsible for much of the design work in the early years. Joshua Field was the eldest of the eight young men who in 1818 founded the Institution of Civil Engineers; he was the first Chairman of the Institution and later became a vice-president. He was the only one of the founders to be elected President and was the first mechanical engineer to hold that office. James Nasmyth in his autobiography relates that Joshua Field kept a methodical account of his technical discussions in a series of note books which were later indexed. Some of these diaries have survived, and extracts from the notes he made on a tour of the industrial areas of the Midlands and the North West in 1821 have been published.

At the age of 15 years Bright left the London Merchant Taylors' School to join the two-year-old Electric Telegraph Company. By 1851 he was in charge of the Birmingham telegraph station. After a short time as Assistant Engineer with the newly formed British Telegraph Company, he joined his brother (who was Manager) as Engineer-in-Chief of the English and Irish Magnetic Telegraph Company in Liverpool, for which he laid thousands of miles of underground cable and developed a number of innovations in telegraphy including a resistance box for locating cable faults and a two-tone bell system for signalling. In 1853 he was responsible for the first successful underwater cable between Scotland and Ireland. Three years later, with the American financier Cyrus Field and John Brett, he founded and was Engineer-in-chief of the Atlantic Telegraph Company, which aimed at laying a cable between Ireland and Newfoundland. After several unsuccessful attempts this was finally completed on 5 August 1858, Bright was knighted a month later, but the cable then failed! In 1860 Bright resigned from the Magnetic Telegraph Company to set up an independent consultancy with another engineer, Joseph Latimer Clark, with whom he invented an improved bituminous cable insulation. Two years later he supervised construction of a telegraph cable to India, and in 1865 a further attempt to lay an Atlantic cable using Brunel's new ship, the Great Eastern. This cable broke during laying, but in 1866 a new cable was at last successfully laid and the 1865 cable recovered and repaired. The year 1878 saw extension of the Atlantic cable system to the West Indies and the invention with his brother of a system of neighbourhood fire alarms and even an automatic fire alarm.

In 1861 Bright presented a paper to the British Association for the Advancement of Science on the need for electrical standards, leading to the creation of an organization that still exists in the 1990s. From 1865 until 1868 he was Liberal MP for Greenwich, and he later assisted with preparations for the 1881 Paris Exhibition.

Brinell graduated as an engineer from Boräs Technical School, and his interest in metallurgy began to develop in 1875 when he became an engineer at the ironworks of Lesjöfors and came under the influence of Gustaf Ekman. In 1882 he was appointed Chief Engineer at the Fagersta Ironworks, where he became one of Sweden's leading experts in the manufacture and heat treatment of tool steels.

His reputation in this field was established in 1885 when he published a paper on the structural changes which occurred in steels when they were heated and cooled, and he was among the first to recognize and define the critical points of steel and their importance in heat treatment. Some of these preliminary findings were first exhibited at Stockholm in 1897. His exhibit at the World Exhibition at Paris in 1900 was far more detailed and there he displayed for the first time his method of hardness determination using a steel-ball indenter. For these contributions he was awarded the French Grand Prix and also the Polhem Prize of the Swedish Technical Society.

He was later concerned with evaluating and developing the iron-ore deposits of north Sweden and was one of the pioneers of the electric blast-furnace. In 1903 he became Chief Engineer of the Jernkontoret and remained there until 1914. In this capacity and as Editor of the Jernkontorets Annaler he made significant contributions to Swedish metallurgy. His pioneer work on abrasion resistance, undertaken long before the term tribology had been invented, gained him the Rinman Medal, awarded by the Jernkontoret in 1920.

William Jessop inherited from his father a natural ability in engineering, and because of his father's association with John Smeaton in the construction of Eddystone Lighthouse he was accepted by Smeaton as a pupil in 1759 at the age of 14. Smeaton was so impressed with his ability that Jessop was retained as an assistant after completion of his pupilage in 1767. As such he carried out field-work, making surveys on his own, but in 1772 he was recommended to the Aire and Calder Committee as an independent engineer and his first personally prepared report was made on the Haddlesey Cut, Selby Canal. It was in this report that he gave his first evidence before a Parliamentary Committee. He later became Resident Engineer on the Selby Canal, and soon after he was elected to the Smeatonian Society of Engineers, of which he later became Secretary for twenty years. Meanwhile he accompanied Smeaton to Ireland to advise on the Grand Canal, ultimately becoming Consulting Engineer until 1802, and was responsible for Ringsend Docks, which connected the canal to the Liffey and were opened in 1796. From 1783 to 1787 he advised on improvements to the River Trent, and his ability was so recognized that it made his reputation. From then on he was consulted on the Cromford Canal (1789–93), the Leicester Navigation (1791–4) and the Grantham Canal (1793–7); at the same time he was Chief Engineer of the Grand Junction Canal from 1793 to 1797 and then Consulting Engineer until 1805. He also engineered the Barnsley and Rochdale Canals. In fact, there were few canals during this period on which he was not consulted. It has now been established that Jessop carried the responsibility for the Pont-Cysyllte Aqueduct in Wales and also prepared the estimates for the Caledonian Canal in 1804. In 1792 he became a partner in the Butterley ironworks and thus became interested in railways. He proposed the Surrey Iron Railway in 1799 and prepared for the estimates; the line was built and opened in 1805. He was also the Engineer for the 10 mile (16 km) long Kilmarnock \& Troon Railway, the Act for which was obtained in 1808 and was the first Act for a public railway in Scotland. Jessop's advice was sought on drainage works between 1785 and 1802 in the lowlands of the Isle of Axholme, Holderness, the Norfolk Marshlands, and the Axe and Brue area of the Somerset Levels. He was also consulted on harbour and dock improvements. These included Hull (1793), Portsmouth (1796), Folkestone (1806) and Sunderland (1807), but his greatest dock works were the West India Docks in London and the Floating Harbour at Bristol. He was Consulting Engineer to the City of London Corporation from 1796to 1799, drawing up plans for docks on the Isle of Dogs in 1796; in February 1800 he was appointed Engineer, and three years later, in September 1803, he was appointed Engineer to the Bristol Floating Harbour. Jessop was regarded as the leading civil engineer in the country from 1785 until 1806. He died following a stroke in 1814.

The son of a miller, he received a rudimentary education in the village school. At an early age he was helping his father in the mill, and in 1800 he was apprenticed to a cabinet maker. After four years he returned to work with his father, but, preferring to leave the parental home, he not long afterwards joined a firm of agricultural-machinery makers in Swanton in Norfolk. There he acquired a reputation for making accurate patterns for the iron caster and demonstrated a talent for mechanical invention, patenting a self-regulating windmill sail in 1807. He then set up on his own as a millwright, but he found he could better himself by joining the engineering works of Ransomes of Ipswich in 1812. He was soon appointed their Chief Engineer, and after nine years he became a partner in the firm until he moved to London in 1826. Around 1818 he invented the treadmill, with the aim of putting prisoners to useful work in grinding corn and other applications. It was rapidly adopted by the principal prisons, more as a means of punishment than an instrument of useful work.

From 1814 Cubitt had been gaining experience in civil engineering, and upon his removal to London his career in this field began to take off. He was engaged on many canal-building projects, including the Oxford and Liverpool Junction canals. He accomplished some notable dock works, such as the Bute docks at Cardiff, the Middlesborough docks and the coal drops on the river Tees. He improved navigation on the river Severn and compiled valuable reports on a number of other leading rivers.

The railway construction boom of the 1840s provided him with fresh opportunities. He engineered the South Eastern Railway (SER) with its daringly constructed line below the cliffs between Folkestone and Dover; the railway was completed in 1843, using massive charges of explosive to blast a way through the cliffs. Cubitt was Consulting Engineer to the Great Northern Railway and tried, with less than his usual success, to get the atmospheric system to work on the Croydon Railway.

When the SER began a steamer service between Folkestone and Boulogne, Cubitt was engaged to improve the port facilities there and went on to act as Consulting Engineer to the Boulogne and Amiens Railway. Other commissions on the European continent included surveying the line between Paris and Lyons, advising the Hanoverian government on the harbour and docks at Hamburg and directing the water-supply works for Berlin.

Cubitt was actively involved in the erection of the Crystal Palace for the Great Exhibition of 1851; in recognition of this work Queen Victoria knighted him at Windsor Castle on 23 December 1851.

Cubitt's son Joseph (1811–72) was also a notable civil engineer, with many railway and harbour works to his credit.

After a general education at Vickery's School at Southsea, Izod (who pronounced his name Izzod, not Izod) started his career as a premium apprentice at the works of Maudslay, Sons and Field at Lambeth in January 1893. When in 1995 he was engaged in the installation of machinery in HMS Renown at Pembroke, he gained some notoriety for his temerity in ordering Rear Admiral J.A.Fisher, who had no pass, out of the main engine room. He subsequently worked at Portsmouth Dockyard where the battleships Caesar and Gladiator were being engined by Maudslay's. From 1898 to 1900 Izod worked as a Demonstrator in the laboratories of University College London, and he was then engaged by Captain H. Riall Sankey as his Personal Assistant at the Rugby works of Willans and Robinson. Soon after going to Rugby, Izod was asked by Sankey to examine a failed gun barrel and try to ascertain why it burst in testing. Conventional mechanical testing did not reveal any significant differences in the properties of good and bad material. Izod found, however, that, when specimens from the burst barrel were notched, gripped in a vice, and then struck with a hammer they broke in a brittle manner, whereas sounder material merely bent plastically. From these findings his well-known notched-bar impact test emerged. His address to the British Association in September 1903 described the test and his testing machine, and was subsequently published in Engineering. Izod never claimed any priority for this method of test, and generously acknowledged his predecessors in this field, Swedenborg, Fremont, Arnold and Bent Russell. The Izod Test was rapidly adopted by the English-speaking world, although Izod himself, being a busy man, did little to publicize his work, which was introduced to the engineering world largely through the efforts of Captain Sankey. Izod became Assistant Managing Director at Willans, and in 1910 was appointed Chief Consulting Mechanical and Electrical Engineer to the Central Mining Corporation at Johannesburg. He became Managing Director of the Rand Mines in 1918, and returned to the UK in 1927 to become the Managing Director of Weymann Motor Bodies Ltd of Addlestone. As Chairman of this company he extended its activitiesconsiderably.

Kilby spent most of his childhood in Great Bend, Kansas, where he often accompanied his father, an electrical power engineer, on his maintenance rounds. Working in the blizzard of 1937, his father borrowed a "ham" radio, and this fired Jack to study for his amateur licence (W9GTY) and to construct his own equipment while still a student at Great Bend High School. In 1941 he entered the University of Illinois, but four months later, after the attack on Pearl Harbor, he was enlisted in the US Army and found himself working in a radio repair workshop in India. When the war ended he returned to his studies, obtaining his BSEE from Illinois in 1947 and his MSEE from the University of Wisconsin. He then joined Centralab, a small electronics firm in Milwaukee owned by Globe-Union. There he filed twelve patents, including some for reduced titanate capacitors and for Steatite-packing of transistors, and developed a transistorized hearing-aid. During this period he also attended a course on transistors at Bell Laboratories. In May 1958, concerned to gain experience in the field of number processing, he joined Texas Instruments in Dallas. Shortly afterwards, while working alone during the factory vacation, he conceived the idea of making monolithic, or integrated, circuits by diffusing impurities into a silicon substrate to create P-N junctions. Within less than a month he had produced a complete oscillator on a chip to prove that the technology was feasible, and the following year at the 1ERE Show he demonstrated a germanium integrated-circuit flip-flop. Initially he was granted a patent for the idea, but eventually, after protracted litigation, priority was awarded to Robert Noyce of Fairchild. In 1965 he was commissioned by Patrick Haggerty, the Chief Executive of Texas Instruments, to make a pocket calculator based on integrated circuits, and on 14 April 1971 the world's first such device, the Pocketronic, was launched onto the market. Costing $150 (and weighing some 2½ lb or 1.1 kg), it was an instant success and in 1972 some 5 million calculators were sold worldwide. He left Texas Instruments in November 1970 to become an independent consultant and inventor, working on, amongst other things, methods of deriving electricity from sunlight.

Kirk was a son of the manse, and after attending school at Arbroath he proceeded to Edinburgh University. Following graduation he served an apprenticeship at the Vulcan Foundry, Glasgow, before serving first as Chief Draughtsman with the Thames shipbuilders and engineers Maudslay Sons \& Field, and later as Engineer of Paraffin Young's Works at Bathgate and West Calder in Lothian. He was credited with the inventions of many ingenious appliances and techniques for improving production in these two establishments. About 1866 Kirk returned to Glasgow as Manager of the Cranstonhill Engine Works, then moved to Elder's Shipyard (later known as the Fairfield Company) as Engineering Manager. There he made history in producing the world's first triple-expansion engines for the single-screw steamship Propontis in 1874. That decade was to confirm the Clyde's leading role as shipbuilders to the world and to establish the iron ship with efficient reciprocating machinery as the workhorse of the British Merchant Marine. Upon the death of the great Clyde shipbuilder Robert Napier in 1876, Kirk and others took over as partners in the shipbuilding yard and engine shops of Robert Napier \& Sons. There in 1881 they built a ship that is acknowledged as one of the masterpieces of British shipbuilding: the SS Aberdeen for George Thompson's Aberdeen Line to the Far East. In this ship the fullest advantage was taken of high steam temperatures and pressures, which were expanded progressively in a three-cylinder configuration. The Aberdeen, in its many voyages from London to China and Japan, was to prove the efficiency of these engines that had been so carefully designed in Glasgow. In the following years Dr Kirk (he has always been known as Doctor, although his honorary LLD was only awarded by Glasgow University in 1888) persuaded the Admiralty and several shipping companies to accept not only triple-expansion machinery but also the use of mild steel in ship construction. The successful SS Parisian, built for the Allan Line of Glasgow, was one of these pioneer ships.

Maxim was born the son of a pioneer farmer who later became a wood turner. Young Maxim was first apprenticed to a carriage maker and then embarked on a succession of jobs before joining his uncle in his engineering firm in Massachusetts in 1864. As a young man he gained a reputation as a boxer, but it was his uncle who first identified and encouraged Hiram's latent talent for invention.

It was not, however, until 1878, when Maxim joined the first electric-light company to be established in the USA, as its Chief Engineer, that he began to make a name for himself. He developed an improved light filament and his electric pressure regulator not only won a prize at the first International Electrical Exhibition, held in Paris in 1881, but also resulted in his being made a Chevalier de la Légion d'honneur. While in Europe he was advised that weapons development was a more lucrative field than electricity; consequently, he moved to England and established a small laboratory at Hatton Garden, London. He began by investigating improvements to the Gatling gun in order to produce a weapon with a faster rate of fire and which was more accurate. In 1883, by adapting a Winchester carbine, he successfully produced a semi-automatic weapon, which used the recoil to cock the gun automatically after firing. The following year he took this concept a stage further and produced a fully automatic belt-fed weapon. The recoil drove barrel and breechblock to the vent. The barrel then halted, while the breechblock, now unlocked from the former, continued rearwards, extracting the spent case and recocking the firing mechanism. The return spring, which it had been compressing, then drove the breechblock forward again, chambering the next round, which had been fed from the belt, as it did so. Keeping the trigger pressed enabled the gun to continue firing until the belt was expended. The Maxim gun, as it became known, was adopted by almost every army within the decade, and was to remain in service for nearly fifty years. Maxim himself joined forces with the large British armaments firm of Vickers, and the Vickers machine gun, which served the British Army during two world wars, was merely a refined version of the Maxim gun.

Maxim's interests continued to occupy several fields of technology, including flight. In 1891 he took out a patent for a steam-powered aeroplane fitted with a pendulous gyroscopic stabilizer which would maintain the pitch of the aeroplane at any desired inclination (basically, a simple autopilot). Maxim decided to test the relationship between power, thrust and lift before moving on to stability and control. He designed a lightweight steam-engine which developed 180 hp (135 kW) and drove a propeller measuring 17 ft 10 in. (5.44 m) in diameter. He fitted two of these engines into his huge flying machine testrig, which needed a wing span of 104 ft (31.7 m) to generate enough lift to overcome a total weight of 4 tons. The machine was not designed for free flight, but ran on one set of rails with a second set to prevent it rising more than about 2 ft (61 cm). At Baldwyn's Park in Kent on 31 July 1894 the huge machine, carrying Maxim and his crew, reached a speed of 42 mph (67.6 km/h) and lifted off its rails. Unfortunately, one of the restraining axles broke and the machine was extensively damaged. Although it was subsequently repaired and further trials carried out, these experiments were very expensive. Maxim eventually abandoned the flying machine and did not develop his idea for a stabilizer, turning instead to other projects. At the age of almost 70 he returned to the problems of flight and designed a biplane with a petrol engine: it was built in 1910 but never left the ground.

In all, Maxim registered 122 US and 149 British patents on objects ranging from mousetraps to automatic spindles. Included among them was a 1901 patent for a foot-operated suction cleaner. In 1900 he became a British subject and he was knighted the following year. He remained a larger-than-life figure, both physically and in character, until the end of his life.

Matthew Murray was apprenticed at the age of 14 to a blacksmith who probably also did millwrighting work. He then worked as a journeyman mechanic at Stockton-on-Tees, where he had experience with machinery for a flax mill at Darlington. Trade in the Stockton area became slack in 1788 and Murray sought work in Leeds, where he was employed by John Marshall, who owned a flax mill at Adel, located about 5 miles (8 km) from Leeds. He soon became Marshall's chief mechanic, and when in 1790 a new mill was built in the Holbeck district of Leeds by Marshall and his partner Benyon, Murray was responsible for the installation of the machinery. At about this time he took out two patents relating to improvements in textile machinery.

In 1795 he left Marshall's employment and, in partnership with David Wood (1761– 1820), established a general engineering and millwrighting business at Mill Green, Holbeck. In the following year the firm moved to a larger site at Water Lane, Holbeck, and additional capital was provided by two new partners, James Fenton (1754–1834) and William Lister (1796–1811). Lister was a sleeping partner and the firm was known as Fenton, Murray \& Wood and was organized so that Fenton kept the accounts, Wood was the administrator and took charge of the workshops, while Murray provided the technical expertise. The factory was extended in 1802 by the construction of a fitting shop of circular form, after which the establishment became known as the "Round Foundry".

In addition to textile machinery, the firm soon began the manufacture of machine tools and steam-engines. In this field it became a serious rival to Boulton \& Watt, who privately acknowledged Murray's superior craftsmanship, particularly in foundry work, and resorted to some industrial espionage to discover details of his techniques. Murray obtained patents for improvements in steam engines in 1799, 1801 and 1802. These included automatic regulation of draught, a mechanical stoker and his short-D slide valve. The patent of 1801 was successfully opposed by Boulton \& Watt. An important contribution of Murray to the development of the steam engine was the use of a bedplate so that the engine became a compact, self-contained unit instead of separate components built into an en-gine-house.

Murray was one of the first, if not the very first, to build machine tools for sale. However, this was not the case with the planing machine, which he is said to have invented to produce flat surfaces for his slide valves. Rather than being patented, this machine was kept secret, although it was apparently in use before 1814.

In 1812 Murray was engaged by John Blenkinsop (1783–1831) to build locomotives for his rack railway from Middleton Colliery to Leeds (about 3 1/2 miles or 5.6 km). Murray was responsible for their design and they were fitted with two double-acting cylinders and cranks at right angles, an important step in the development of the steam locomotive. About six of these locomotives were built for the Middleton and other colliery railways and some were in use for over twenty years. Murray also supplied engines for many early steamboats. In addition, he built some hydraulic machinery and in 1814 patented a hydraulic press for baling cloth.

Murray's son-in-law, Richard Jackson, later became a partner in the firm, which was then styled Fenton, Murray \& Jackson. The firm went out of business in 1843.

Bramah was the son of a tenant farmer and was educated at the village school before being apprenticed to a local carpenter, Thomas Allot. He walked to London c.1773 and found work with a Mr Allen that included the repair of some of the comparatively rare water-closets of the period. He invented and patented one of his own, which was followed by a water cock in 1783. His next invention, a greatly improved lock, involved the devising of a number of special machine tools, for it was one of the first devices involving interchangeable components in its manufacture. In this he had the help of Henry Maudslay, then a young and unknown engineer, who became Bramah's foreman before setting up business on his own. In 1784 he moved his premises from Denmark Street, St Giles, to 124 Piccadilly, which was later used as a showroom when he set up a factory in Pimlico. He invented an engine for putting out fires in 1785 and 1793, in effect a reciprocating rotary-vane pump. He undertook the refurbishment and modernization of Norwich waterworks c.1793, but fell out with Robert Mylne, who was acting as Consultant to the Norwich Corporation and had produced a remarkably vague specification. This was Bramah's only venture into the field of civil engineering.

In 1797 he acted as an expert witness for Hornblower \& Maberley in the patent infringement case brought against them by Boulton and Watt. Having been cut short by the judge, he published his proposed evidence in "Letter to the Rt Hon. Sir James Eyre, Lord Chief Justice of the Common Pleas…etc". In 1795 he was granted his most important patent, based on Pascal's Hydrostatic Paradox, for the hydraulic press which also incorporated the concept of hydraulics for the transmission of both power and motion and was the foundation of the whole subsequent hydraulic industry. There is no truth in the oft-repeated assertion originating from Samuel Smiles's Industrial Biography (1863) that the hydraulic press could not be made to work until Henry Maudslay invented the self-sealing neck leather. Bramah used a single-acting upstroking ram, sealed only at its base with a U-leather. There was no need for a neck leather.

He also used the concept of the weight-loaded, in this case as a public-house beer-engine. He devised machinery for carbonating soda water. The first banknote-numbering machine was of his design and was bought by the Bank of England. His development of a machine to cut twelve nibs from one goose quill started a patent specification which ended with the invention of the fountain pen, patented in 1809. His coach brakes were an innovation that was followed bv a form of hydropneumatic carriage suspension that was somewhat in advance of its time, as was his patent of 1812. This foresaw the introduction of hydraulic power mains in major cities and included the telescopic ram and the air-loaded accumulator.

In all Joseph Bramah was granted eighteen patents. On 22 March 1813 he demonstrated a hydraulic machine for pulling up trees by the roots in Hyde Park before a large crowd headed by the Duke of York. Using the same machine in Alice Holt Forest in Hampshire to fell timber for ships for the Navy, he caught a chill and died soon after at his home in Pimlico.

In 1912 Donald Douglas went to the Massachusetts Institute of Technology to study aeronautical engineering. After graduating in this relatively new subject he joined the Glenn L.Martin Company as Chief Engineer. In 1920 he founded the Davis-Douglas Company in California to build an aircraft capable of flying across America non-stop: unfortunately, the Cloudster failed to achieve its target. Douglas reorganized the company in 1921 as the Douglas Company (later it became the Douglas Aircraft Company). In 1924 a team of US Army personnel made the first round-the-world flight in specially designed Douglas World Cruisers, a feat which boosted Douglas's reputation considerably. This reputation was further enhanced by his airliner, designed in 1935, that revolutionized air travel: the Douglas Commercial 3, or DC-3, of which some 13,000 were built. A series of piston-engined airliners followed, culminating in the DC-7. Meanwhile, in the military field, Douglas aircraft played a major part in the Second World War. In the jet age Douglas continued to produce a wide range of successful civil and military aircraft, and the company also moved into the rocket and guided missile business. In 1966 Donald W. Douglas was still Chairman of the company, with Donald W.Douglas Jr as President. In 1967 the company merged with the McDonnell Aircraft Company to become the giant McDonnell Douglas Corporation.

From his high-school days, Pierce showed an interest in science and in science fiction, writing under the pseudonym of J.J.Coupling. After gaining Bachelor's, Master's and PhD degrees at the California Institute of Technology (CalTech) in Pasadena in 1933, 1934 and 1936, respectively, Pierce joined the Bell Telephone Laboratories in New York City in 1936. There he worked on improvements to the travelling-wave tube, in which the passage of a beam of electrons through a helical transmission line at around 7 per cent of the speed of light was made to provide amplification at 860 MHz. He also devised a new form of electrostatically focused electron-multiplier which formed the basis of a sensitive detector of radiation. However, his main contribution to electronics at this time was the invention of the Pierce electron gun—a method of producing a high-density electron beam. In the Second World War he worked with McNally and Shepherd on the development of a low-voltage reflex klystron oscillator that was applied to military radar equipment.

In 1952 he became Director of Electronic Research at the Bell Laboratories' establishment, Murray Hill, New Jersey. Within two years he had begun work on the possibility of round-the-world relay of signals by means of communication satellites, an idea anticipated in his early science-fiction writings (and by Arthur C. Clarke in 1945), and in 1955 he published a paper in which he examined various possibilities for communications satellites, including passive and active satellites in synchronous and non-synchronous orbits. In 1960 he used the National Aeronautics and Space Administration 30 m (98 1/2 ft) diameter, aluminium-coated Echo 1 balloon satellite to reflect telephone signals back to earth. The success of this led to the launching in 1962 of the first active relay satellite (Telstar), which weighed 170 lb (77 kg) and contained solar-powered rechargeable batteries, 1,000 transistors and a travelling-wave tube capable of amplifying the signal 10,000 times. With a maximum orbital height of 3,500 miles (5,600 km), this enabled a variety of signals, including full bandwidth television, to be relayed from the USA to large receiving dishes in Europe.

From 1971 until his "retirement" in 1979, Pierce was Professor of Electrical Engineering at CalTech, after which he became Chief Technologist at the Jet Propulsion Laboratories, also in Pasadena, and Emeritus Professor of Engineering at Stanford University.
