At the age of 23, Eisler obtained a Diploma in Engineering from the Technical University of Vienna. Because of the growing Nazi influence in Austria, he then accepted a post with the His Master's Voice (HMV) agents in Belgrade, where he worked on the problems of radio reception and sound transmission in railway trains. However, he soon returned to Vienna to found a weekly radio journal and file patents on graphical sound recording (for which he received a doctorate) and on a system of stereoscopic television based on lenticular vertical scanning.

In 1936 he moved to England and sold the TV patent to Marconi for £250. Unable to find a job, he carried out experiments in his rooms in a Hampstead boarding-house; after making circuits using strip wires mounted on bakelite sheet, he filed his first printed-circuit patent that year. He then tried to find ways of printing the circuits, but without success. Obtaining a post with Odeon Theatres, he invented a sound-level control for films and devised a mirror-drum continuous-film projector, but with the outbreak of war in 1939, when the company was evacuated, he chose to stay in London and was interned for a while. Released in 1941, he began work with Henderson and Spalding, a firm of lithographic printers, to whom he unwittingly assigned all future patents for the paltry sum of £1. In due course he perfected a means of printing conducting circuits and on 3 February 1943 he filed three patents covering the process. The British Ministry of Defence rejected the idea, considering it of no use for military equipment, but after he had demonstrated the technique to American visitors it was enthusiastically taken up in the US for making proximity fuses, of which many millions were produced and used for the war effort. Subsequently the US Government ruled that all air-borne electronic circuits should be printed.

In the late 1940s the Instrument Department of Henderson and Spalding was split off as Technograph Printed Circuits Ltd, with Eisler as Technical Director. In 1949 he filed a further patent covering a multilayer system; this was licensed to Pye and the Telegraph Condenser Company. A further refinement, patented in the 1950s, the use of the technique for telephone exchange equipment, but this was subsequently widely infringed and although he negotiated licences in the USA he found it difficult to license his ideas in Europe. In the UK he obtained finance from the National Research and Development Corporation, but they interfered and refused money for further development, and he eventually resigned from Technograph. Faced with litigation in the USA and open infringement in the UK, he found it difficult to establish his claims, but their validity was finally agreed by the Court of Appeal (1969) and the House of Lords (1971).

As a freelance inventor he filed many other printed-circuit patents, including foil heating films and batteries. When his Patent Agents proved unwilling to fund the cost of filing and prosecuting Complete Specifications he set up his own company, Eisler Consultants Ltd, to promote food and space heating, including the use of heated cans and wallpaper! As Foil Heating Ltd he went into the production of heating films, the process subsequently being licensed to Thermal Technology Inc. in California.

Interested from childhood in anything mechanical, as a teenager Armstrong constructed a variety of wireless equipment in the attic of his parents' home, including spark-gap transmitters and receivers with iron-filing "coherer" detectors capable of producing weak Morse-code signals. In 1912, while still a student of engineering at Columbia University, he applied positive, i.e. regenerative, feedback to a Lee De Forest triode amplifier to just below the point of oscillation and obtained a gain of some 1,000 times, giving a receiver sensitivity very much greater than hitherto possible. Furthermore, by allowing the circuit to go into full oscillation he found he could generate stable continuous-waves, making possible the first reliable CW radio transmitter. Sadly, his claim to priority with this invention, for which he filed US patents in 1913, the year he graduated from Columbia, led to many years of litigation with De Forest, to whom the US Supreme Court finally, but unjustly, awarded the patent in 1934. The engineering world clearly did not agree with this decision, for the Institution of Radio Engineers did not revoke its previous award of a gold medal and he subsequently received the highest US scientific award, the Franklin Medal, for this discovery.

During the First World War, after some time as an instructor at Columbia University, he joined the US Signal Corps laboratories in Paris, where in 1918 he invented the superheterodyne, a major contribution to radio-receiver design and for which he filed a patent in 1920. The principle of this circuit, which underlies virtually all modern radio, TV and radar reception, is that by using a local oscillator to convert, or "heterodyne", a wanted signal to a lower, fixed, "intermediate" frequency it is possible to obtain high amplification and selectivity without the need to "track" the tuning of numerous variable circuits.

Returning to Columbia after the war and eventually becoming Professor of Electrical Engineering, he made a fortune from the sale of his patent rights and used part of his wealth to fund his own research into further problems in radio communication, particularly that of receiver noise. In 1933 he filed four patents covering the use of wide-band frequency modulation (FM) to achieve low-noise, high-fidelity sound broadcasting, but unable to interest RCA he eventually built a complete broadcast transmitter at his own expense in 1939 to prove the advantages of his system. Unfortunately, there followed another long battle to protect and exploit his patents, and exhausted and virtually ruined he took his own life in 1954, just as the use of FM became an established technique.

From an early age he was absorbed by phenomena of physics to the exclusion of all other subjects, including mathematics. When choosing his subjects for the final three years in Borgedydskolen in Christianshavn (Copenhagen) before university, he opted for languages and history. At the University of Copenhagen he embarked on the study of medicine in 1889, but broke it off and was apprenticed to the machine firm of A/S Frichs Eftf. in Aarhus. He was employed between 1893 and 1899 as a mechanic and assistant in the laboratory of the Copenhagen Telephone Company KTAS. Eventually he advanced to be Head of the line fault department. This suited his desire for experiment and measurement perfectly. After the invention of the telegraphone in 1898, he left the laboratory and with responsible business people he created Aktieselskabet Telegrafonen, Patent Poulsen in order to develop it further, together with Peder Oluf Pedersen (1874– 1941). Pedersen brought with him the mathematical background which eventually led to his professorship in electronic engineering in 1922.

The telegraphone was the basis for multinational industrial endeavours after it was demonstrated at the 1900 World's Exhibition in Paris. It must be said that its strength was also its weakness, because the telegraphone was unique in bringing sound recording and reproduction to the telephone field, but the lack of electronic amplifiers delayed its use outside this and the dictation fields (where headphones could be used) until the 1920s. However, commercial interest was great enough to provoke a number of court cases concerning patent infringement, in which Poulsen frequently figured as a witness.

In 1903–4 Poulsen and Pedersen developed the arc generator for continuous radio waves which was used worldwide for radio transmitters in competition with Marconi's spark-generating system. The inspiration for this work came from the research by William Duddell on the musical arc. Whereas Duddell had proposed the use of the oscillations generated in his electric arc for telegraphy in his 1901 UK patent, Poulsen contributed a chamber of hydrogen and a transverse magnetic field which increased the efficiency remarkably. He filed patent applications on these constructions from 1902 and the first publication in a scientific forum took place at the International Electrical Congress in St Louis, Missouri, in 1904.

In order to use continuous waves efficiently (the high frequency constituted a carrier), Poulsen developed both a modulator for telegraphy and a detector for the carrier wave. The modulator was such that even the more primitive spark-communication receivers could be used. Later Poulsen and Pedersen developed frequency-shift keying.

The Amalgamated Radio-Telegraph Company Ltd was launched in London in 1906, combining the developments of Poulsen and those of De Forest Wireless Telegraph Syndicate. Poulsen contributed his English and American patents. When this company was liquidated in 1908, its assets were taken over by Det Kontinentale Syndikat for Poulsen Radio Telegrafi, A/S in Copenhagen (liquidated 1930–1). Some of the patents had been sold to C.Lorenz AG in Berlin, which was very active.

The arc transmitting system was in use worldwide from about 1910 to 1925, and the power increased from 12 kW to 1,000 kW. In 1921 an exceptional transmitter rated at 1,800 kW was erected on Java for communications with the Netherlands. More than one thousand installations had been in use worldwide. The competing systems were initially spark transmitters (Marconi) and later rotary converters ( Westinghouse). Similar power was available from valve transmitters only much later.

From c. 1912 Poulsen did not contribute actively to further development. He led a life as a well-respected engineer and scientist and served on several committees. He had his private laboratory and made experiments in the composition of matter and certain resonance phenomena; however, nothing was published. It has recently been suggested that Poulsen could not have been unaware of Oberlin Smith's work and publication in 1888, but his extreme honesty in technical matters indicates that his development was indeed independent. In the case of the arc generator, Poulsen was always extremely frank about the inspiration he gained from earlier developers' work.

He received his education at Dulwich College and in 1922 graduated with a BSc from University College, London. He had an early interest in the application of valve amplifiers, and after graduating he was employed by J.E.Hough, Edison Bell Works, to develop a line of radio-receiving equipment. However, he became interested in the mechanical (and later electrical) side of recording and from 1925 developed principles and equipment. In particular he developed capacitor microphones, not only for in-house work but also commercially, until the mid-1930s. The Edison Bell company did not survive the Depression and closed in 1933. Voigt founded his own company, Voigt Patents Ltd, concentrating on loudspeakers for cinemas and developing horn loudspeakers for domestic use. During the Second World War he continued to develop loudspeaker units and gramophone pick-ups, and in 1950 he emigrated to Toronto, Canada, but his company closed. Voigt taught electronics, and from 1960 to 1969 he was employed by the Radio Regulations Laboratory in Ottawa. After retirement he worked with theoretical cosmology and fundamental interactions.

He was a very bright scholar and received a BSc in electrical technology from City and Guilds College in 1923. He joined International Western Electric (later to become Standard Telephone and Cables) in 1924 after a period as an instructor/demonstrator at City and Guilds. He was instrumental in the design of telephone measuring equipment and in international committee work for standards for long-distance telephony.

From 1929 Blumlein was employed by the Columbia Graphophone Company to develop an electric recording cutterhead that would be independent of Western Electric's patents for the system developed by Maxfield and Harrison. He attacked the problems in a most systematic fashion, and within a year he had developed a moving-coil cutterhead that was much more linear than the iron-cored systems known at the time. Eventually Blumlein designed a complete line of recording equipment, from microphone and through-power amplifiers. The design was used by Columbia; after the merger with the Gramophone Company in 1931 to form Electrical and Musical Industries Ltd (later known as EMI) it became the company standard, certainly for coarse-groove records, until c.1950.

Blumlein became interested in stereophony (binaural sound), and developed and demonstrated a complete line of equipment, from correctly placed microphones via two-channel records and stereo pick-ups to correctly placed loudspeakers. The advent of silent surfaces of vinyl records made this approach commercial from the late 1950s. His approach was independent and quite different from that of A.C. Keller.

His extreme facility for creating innovative solutions to electronic problems was used in EMI's development from 1934 to 1938 of the electronic television system, which became the BBC standard of 405 lines after the Second World War, when television broadcasting again became possible. Independent of official requirements, EMI developed a 60 MHz radar system and Blumlein was involved in the development of a centimetric radar and display system. It was during testing of this aircraft mounted equipment that he was killed in a crash.

Whilst still in high school, Farnsworth became interested in the possibility of television and conceived many of the basic features of a practicable system of TV broadcast and reception. Following two years of study at the Brigham Young University in Provo, Utah, in 1926 he cofounded the Crocker Research Laboratories in San Francisco, subsequently Farnsworth Television Inc. (1929) and Farnsworth Radio \& Television Corporation, Fort Wayne, Indiana (1938). There he began a lifetime of research, primarily in the field of television. In 1927, with the backing of the Radio Corporation of America (RCA) and the collaboration of Vladimir Zworykin, he demonstrated the first all-electronic television system, based on his early ideas for an image dissector tube, the first electronic equivalent of the Nipkow disc. With this rudimentary sixty-line system he was able to transmit a recognizable dollar sign and file the first of many TV patents. From then on he contributed to a variety of developments in the fields of vacuum tubes, radar and atomic-power generation, with patents on cathode ray tubes, amplifying and pick-up tubes, electron multipliers and photoelectric materials.

After initial education at Trinity College School, Port Hope, Ontario, Fessenden studied at Bishops University, Lennoxville, Quebec. When he graduated in 1885, he became Principal of the Whitney Institute in Bermuda, but he left the following year to go to New York in pursuit of his scientific interests. There he met Edison and eventually became Chief Chemist at the latter's Laboratory in Orange, New Jersey. In 1890 he moved to the Westinghouse Electric and Manufacturing Company, and two years later he returned to an academic career as Professor of Electrical Engineering, initially at Purdue University, Lafayette, Indiana, and then at the Western University of Pennsylvania, where he worked on wireless communication. From 1900 to 1902 he carried out experiments in wireless telegraphy at the US Weather Bureau, filing several patents relating to wire and liquid thermal detectors, or barretters. Following this he set up the National Electric Signalling Company; under his direction, Alexanderson and other engineers at the General Electric Company developed a high-frequency alternator that enabled him to build the first radiotelephony transmitter at Brant Rock, Massachusetts. This made its initial broadcast of speech and music on 24 December 1906, received by ship's wireless operators several hundred miles away. Soon after this the transmitter was successfully used for two-way wireless telegraphy communication with Scotland. Following this landmark event, Fessenden produced numerous inventions, including a radio compass, an acoustic depth-finder and several submarine signalling devices, a turboelectric drive for battleships and, notably, in 1912 the heterodyne principle used in radio receivers to convert signals to a lower (intermediate) frequency.

George B.Grant was descended from families who came from Britain in the seventeenth century and was educated at the Bridgton (Maine) Academy, the Chandler Scientific School of Dartmouth College and the Lawrence Scientific School of Harvard College, where he graduated with the degree of BS in 1873. As an undergraduate he became interested in calculating machines, and his paper "On a new difference engine" was published in the American Journal of Science in August 1871. He also took out his first patents relating to calculating machines in 1872 and 1873. A machine of his design known as "Grant's Difference Engine" was exhibited at the Centennial Exposition in Philadelphia in 1876. Similar machines were also manufactured for sale; being sturdy and reliable, they did much to break down the prejudice against the use of calculating machines in business. Grant's work on calculating machines led to a requirement for accurate gears, so he established a machine shop for gear cutting at Charlestown, Massachusetts. He later moved the business to Boston and incorporated it under the name of Grant's Gear Works Inc., and continued to control it until his death. He also established two other gear-cutting shops, the Philadelphia Gear Works Inc., which he disposed of in 1911, and the Cleveland Gear Works Inc., which he also disposed of after a few years. Grant's commercial success was in connection with gear cutting and in this field he obtained several patents and contributed articles to the American Machinist. However, he continued to take an interest in calculating machines and in his later years carried out experimental work on their development.

He graduated from the Dover Academy (Delaware) in 1882 and was apprenticed in a machine-repair firm in Philadelphia and studied in evening classes at the Spring Garden Institute. In 1888 he took employment in a small Philadelphia machine shop owned by Andrew Scull, specializing in repair and bookbinding machinery. After travels in the western part of the US, in 1891 he became a partner in Scull \& Johnson, Manufacturing Machinists, and established a further company, the New Jersey Wire Stitching Machine Company. He bought out Andrew Scull's interest in October 1894 (the last instalment being paid in 1897) and became an independent general machinist. In 1896 he had perfected a spring motor for the Berliner flat-disc gramophone, and he started experimenting with a more direct method of recording in a spiral groove: that of cutting in wax. Co-operation with Berliner eventually led to the incorporation of the Victor Talking Machine Company in 1901. The innumerable court cases stemming from the fact that so many patents for various elements in sound recording and reproduction were in very many hands were brought to an end in 1903 when Johnson was material in establishing cross-licencing agreements between Victor, Columbia Graphophone and Edison to create what is known as a patent pool. Early on, Johnson had a thorough experience in all matters concerning the development and manufacture of both gramophones and records. He made and patented many major contributions in all these fields, and his approach was very business-like in that the contribution to cost of each part or process was always a decisive factor in his designs. This attitude was material in his consulting work for the sister company, the Gramophone Company, in London before it set up its own factories in 1910. He had quickly learned the advantages of advertising and of providing customers with durable equipment and records. This motivation was so strong that Johnson set up a research programme for determining the cause of wear in records. It turned out to depend on groove profile, and from 1911 one particular profile was adhered to and processes for transforming the grooves of valuable earlier records were developed. Without precise measuring instruments, he used the durability as the determining factor. Johnson withdrew more and more to the role of manager, and the Victor Talking Machine Company gained such a position in the market that the US anti-trust legislation was used against it. However, a generation change in the Board of Directors and certain erroneous decisions as to product line started a decline, and in February 1926 Johnson withdrew on extended sick leave: these changes led to the eventual sale of Victor. However, Victor survived due to the advent of radio and the electrification of replay equipment and became a part of Radio Corporation of America. In retirement Johnson took up various activities in the arts and sciences and financially supported several projects; his private yacht was used in 1933 in work with the Smithsonian Institution on a deep-sea hydrographie and fauna-collecting expedition near Puerto Rico.

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.

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.

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.
