6 Griffith, Alan Arnold
[br]b. 13 June 1893 London, Englandd. 13 October 1963 Farnborough, England[br]English research engineer responsible for many original ideas, including jet-lift aircraft.[br]Griffith was very much a "boffin", for he was a quiet, thoughtful man who shunned public appearances, yet he produced many revolutionary ideas. During the First World War he worked at the Royal Aircraft Factory, Farnborough, where he carried out research into structural analysis. Because of his use of soap films in solving torsion problems, he was nicknamed "Soap-bubble".During the 1920s Griffith carried out research into gas-turbine design at the Royal Aircraft Establishment (RAE; as the Royal Aircraft Factory had become). In 1929 he made proposals for a gas turbine driving a propeller (a turboprop), but the idea was shelved. In the 1930s he was head of the Engine Department of the RAE and developed multi-stage axial compressors, which were later used in jet engines. This work attracted the attention of E.W. (later Lord) Hives of Rolls-Royce who persuaded Griffith to join Rolls-Royce in 1939. His first major project was a "contra-flow" jet engine, which was a good idea but a practical failure. However, Griffith's axial-flow compressor experience played an important part in the success of Rolls-Royce jet engines from the Avon onwards. He also proposed the bypass principle used for the Conway.Griffith experimented with suction to control the boundary layer on wings, but his main interest in the 1950s centred on vertical-take-off and -landing aircraft. He developed the remarkable "flying bedstead", which consisted of a framework (the bedstead) in which two jet engines were mounted with their jets pointing downwards, thus lifting the machine vertically. It first flew in 1954 and provided much valuable data. The Short SC1 aircraft followed, with four small jets providing lift for vertical take-off and one conventional jet to provide forward propulsion. This flew successfully in the late 1950s and early 1960s. Griffith proposed an airliner with lifting engines, but the weight of the lifting engines when not in use would have been a serious handicap. He retired in 1960.[br]Principal Honours and DistinctionsCBE 1948. FRS 1941. Royal Aeronautical Society Silver Medal 1955; Blériot Medal 1962.BibliographyGriffith produced many technical papers in his early days; for example: 1926, Aerodynamic Theory of Turbine Design, Farnborough.Further ReadingD.Eyre, 1966, "Dr A.A.Griffith, CBE, FRS", Journal of the Royal Aeronautical Society (June) (a detailed obituary).F.W.Armstrong, 1976, "The aero engine and its progress: fifty years after Griffith", Aeronautical Journal (December).O.Stewart, 1966, Aviation: The Creative Ideas, London (provides brief descriptions of Griffith's many projects).JDS -
7 de Havilland, Sir Geoffrey
SUBJECT AREA: Aerospace[br]b. 27 July 1882 High Wycombe, Buckinghamshire, Englandd. 21 May 1965 Stanmore, Middlesex, England[br]English designer of some eighty aircraft from 1909 onwards.[br]Geoffrey de Havilland started experimenting with aircraft and engines of his own design in 1908. In the following year, with the help of his friend Frank Hearle, he built and flew his first aircraft; it crashed on its first flight. The second aircraft used the same engine and made its first flight on 10 September 1910, and enabled de Havilland to teach himself to fly. From 1910 to 1914 he was employed at Farnborough, where in 1912 the Royal Aircraft Factory was established. As Chief Designer and Chief Test Pilot he was responsible for the BE 2, which was the first British military aircraft to land in France in 1914.In May 1914 de Havilland went to work for George Holt Thomas, whose Aircraft Manufacturing Company Ltd (Airco) of Hendon was expanding to design and build aircraft of its own design. However, because de Havilland was a member of the Royal Flying Corps Reserve, he had to report for duty when war broke out in August. His value as a designer was recognized and he was transferred back to Airco, where he designed eight aircraft in four years. Of these, the DH 2, DH 4, DH 5, DH 6 and DH 9 were produced in large numbers, and a modified DH 4A operated the first British cross- Channel air service in 1919.On 25 September 1920 de Havilland founded his own company, the De Havilland Aircraft Company Ltd, at Stag Lane near Edgware, London. During the 1920s and 1930s de Havilland concentrated on civil aircraft and produced the very successful Moth series of small biplanes and monoplanes, as well as the Dragon, Dragon Rapide, Albatross and Flamingo airliners. In 1930 a new site was acquired at Hatfield, Hertfordshire, and by 1934 a modern factory with a large airfield had been established. His Comet racer won the England-Australia air race in 1934 using de Havilland engines. By this time the company had established very successful engine and propeller divisions. The Comet used a wooden stressed-skin construction which de Havilland developed and used for one of the outstanding aircraft of the Second World War: the Mosquito. The de Havilland Engine Company started work on jet engines in 1941 and their Goblin engine powered the Vampire jet fighter first flown by Geoffrey de Havilland Jr in 1943. Unfortunately, Geoffrey Jr and his brother John were both killed in flying accidents. The Comet jet airliner first flew in 1949 and the Trident in 1962, although by 1959 the De Havilland Company had been absorbed into Hawker Siddeley Aviation.[br]Principal Honours and DistinctionsKnight Bachelor 1944.

8 Baumann, Karl
SUBJECT AREA: Steam and internal combustion engines[br]b. 18 April 1884 Switzerlandd. 14 July 1971 Ilkley, Yorkshire[br]Swiss/British mechanical engineer, designer and developer of steam and gas turbine plant.[br]After leaving school in 1902, he went to the Ecole Polytechnique, Zurich, leaving in 1906 with an engineering diploma. He then spent a year with Professor A.Stodola, working on steam engines, turbines and internal combustion engines. He also conducted research in the strength of materials. After this, he spent two years as Research and Design Engineer at the Nuremberg works of Maschinenfabrik Augsburg-Nürnberg. He came to England in 1909 to join the British Westinghouse Co. Ltd in Manchester, and by 1912 was Chief Engineer of the Engine Department of that firm. The firm later became the Metropolitan-Vickers Electrical Co. Ltd (MV), and Baumann rose from Chief Mechanical Engineer through to, by 1929, Special Director and Member of the Executive Management Board; he remained a director until his retirement in 1949.For much of his career, Baumann was in the forefront of power station steam-cycle development, pioneering increased turbine entry pressures and temperatures, in 1916 introducing multi-stage regenerative feed-water heating and the Baumann turbine multi-exhaust. His 105 MW set for Battersea "A" station (1933) was for many years the largest single-axis unit in Europe. From 1938 on, he and his team were responsible for the first axial-flow aircraft propulsion gas turbines to fly in England, and jet engines in the 1990s owe much to the "Beryl" and "Sapphire" engines produced by MV. In particular, the design of the compressor for the Sapphire engine later became the basis for Rolls-Royce units, after an exchange of information between that company and Armstrong-Siddeley, who had previously taken over the aircraft engine work of MV.Further, the Beryl engine formed the basis of "Gatric", the first marine gas turbine propulsion engine.Baumann was elected to full membership for the Institution of Mechanical Engineers in 1929 and a year later was awarded the Thomas Hawksley Gold Medal by that body, followed by their James Clayton Prize in 1948: in the same year he became the thirty-fifth Thomas Hawksley lecturer. Many of his ideas and introductions have stood the test of time, being based on his deep and wide understanding of fundamentals.JB -

11 Ohain, Hans Joachim Pabst von
SUBJECT AREA: Aerospace[br]b. 14 December 1911 Dessau, Germany[br]German engineer who designed the first jet engine to power an aeroplane successfully.[br]Von Ohain studied engineering at the University of Göttingen, where he carried out research on gas-turbine engines, and centrifugal compressors in particular. In 1935 he patented a design for a jet engine (in Britain, Frank Whittle patented his jet-engine design in 1930). Von Ohain was recruited by the Heinkel company in 1936 to develop an engine for a jet aircraft. Ernst Heinkel was impressed by von Ohain's ideas and gave the project a high priority. The first engine was bench tested in September 1937. A more powerful version was developed and tested in air, suspended beneath a Heinkel dive-bomber, during the spring of 1939. A new airframe was designed to house the revolutionary power plant and designated the Heinkel He 178. A short flight was made on 24 August 1939 and the first recognized flight on 27 August. This important achievement received only a lukewarm response from the German authorities. Von Ohain's turbojet engine had a centrifugal compressor and developed a thrust of 380 kg (837 lb). An improved, more powerful, engine was developed and installed in a new twin-engined fighter design, the He 280. This flew on 2 April 1941 but never progressed beyond the prototype stage. By this time two other German companies, BMW and Junkers, were constructing successful turbojets with axial compressors: luckily for the Allies, Hitler was reluctant to pour his hard-pressed resources into this new breed of jet fighters. After the war, von Ohain emigrated to the United States and worked for the Air Force there.[br]Bibliography1929, "The evolution and future of aeropropulsion system", The Jet Age. 40 Years of Jet Aviation, Washington, DC: National Air \& Space Museum, Smithsonian Institution.Further ReadingVon Ohain's work is described in many books covering the history of aviation, and aero engines in particular, for example: R.Schlaifer and S.D.Heron, 1950, Development of Aircraft Engines and fuels, Boston.

12 Hornblower, Jonathan
SUBJECT AREA: Steam and internal combustion engines[br]b. 1753 Cornwall (?), Englandd. 1815 Penryn, Cornwall, England[br]English mining engineer who patented an early form of compound steam engine.[br]Jonathan came from a family with an engineering tradition: his grandfather Joseph had worked under Thomas Newcomen. Jonathan was the sixth child in a family of thirteen whose names all began with "J". In 1781 he was living at Penryn, Cornwall and described himself as a plumber, brazier and engineer. As early as 1776, when he wished to amuse himself by making a small st-eam engine, he wanted to make something new and wondered if the steam would perform more than one operation in an engine. This was the foundation for his compound engine. He worked on engines in Cornwall, and in 1778 was Engineer at the Ting Tang mine where he helped Boulton \& Watt erect one of their engines. He was granted a patent in 1781 and in that year tried a large-scale experiment by connecting together two engines at Wheal Maid. Very soon John Winwood, a partner in a firm of iron founders at Bristol, acquired a share in the patent, and in 1782 an engine was erected in a colliery at Radstock, Somerset. This was probably not very successful, but a second was erected in the same area. Hornblower claimed greater economy from his engines, but steam pressures at that time were not high enough to produce really efficient compound engines. Between 1790 and 1794 ten engines with his two-cylinder arrangement were erected in Cornwall, and this threatened Boulton \& Watt's near monopoly. At first the steam was condensed by a surface condenser in the bottom of the second, larger cylinder, but this did not prove very successful and later a water jet was used. Although Boulton \& Watt proceeded against the owners of these engines for infringement of their patent, they did not take Jonathan Hornblower to court. He tried a method of packing the piston rod by a steam gland in 1781 and his work as an engineer must have been quite successful, for he left a considerable fortune on his death.[br]Bibliography1781, British patent no. 1,298 (compound steam engine).Further ReadingR.Jenkins, 1979–80, "Jonathan Hornblower and the compound engine", Transactions of the Newcomen Society 11.J.Tann, 1979–80, "Mr Hornblower and his crew, steam engine pirates in the late 18th century", Transactions of the Newcomen Society 51.J.Farey, 1827, A Treatise on the Steam Engine, Historical, Practical and Descriptive, reprinted 1971, Newton Abbot: David \& Charles (an almost contemporary account of the compound engine).D.S.L.Cardwell, 1971, From Watt to Clausius.

13 Messerschmitt, Willi E.
SUBJECT AREA: Aerospace[br]b. 26 June 1898 Frankfurt-am-Main, Germanyd. 17 September 1978 Munich, Germany[br]German aircraft designer noted for successful fighters such as the Bf 109, one of the world's most widely produced aircraft.[br]Messerschmitt studied engineering at the Munich Institute of Tchnology and obtained his degree in 1923. By 1926 he was Chief Designer at the Bayerische Flugzeugwerke in Augsburg. Due to the ban on military aircraft in Germany following the First World War, his early designs included gliders, light aircraft, and a series of high-wing airliners. He began to make a major impact on German aircraft design once Hitler came to power and threw off the shackles of the Treaty of Versailles, which so restricted Germany's armed forces. In 1932 he bought out the now-bankrupt Bayerische Flugzeugwerke, but initially, because of enmity between himself and the German aviation minister, was not invited to compete for an air force contract for a single-engined fighter. However, in 1934 Messerschmitt designed the Bf 108 Taifun, a small civil aircraft with a fighter-like appearance. This displayed the quality of his design and the German air ministry was forced to recognize him. As a result, he unveiled the famous Bf 109 fighter which first flew in August 1935; it was used during the Spanish Civil War in 1936–9, and was to become one of the foremost combat aircraft of the Second World War. In 1938, after several name changes, the company became Messerschmitt Aktien-Gesellschaft (and hence a change of prefix from Bf to Me). During April 1939 a Messerschmitt aircraft broke the world air-speed record at 755.14 km/h (469.32 mph): it was entered in the FAI records as a Bf 109R, but was more accurately a new design designated Me 209V-1.During the Second World War, the 5/70P was progressively improved, and eventually almost 35,000 were built. Other successful fighters followed, such as the twin-engined Me 110 which also served as a bomber and night fighter. The Messerschmitt Me 262 twin-engined jet fighter, the first jet aircraft in the world to enter service, flew during the early years of the war, but it was never given a high priority by the High Command and only a small number were in service when the war ended. Another revolutionary Messerschmitt AG design was the Me 163 Komet, the concept of Professor Alexander Lippisch who had joined Messerschmitt's company in 1939; this was the first rocket-propelled fighter to enter service. It was a small tailless design capable of 880 km/hr (550 mph), but its duration under power was only about 10 minutes and it was very dangerous to fly. From late 1944 onwards it was used to intercept the United States Air Force bombers during their daylight raids. At the other end of the scale, Messerschmitt produced the Me 321 Gigant, a huge transport glider which was towed behind a flight of three Me 110s. Later it was equipped with six engines, but it was an easy target for allied fighters. This was a costly white elephant, as was his high-speed twin-engined Me 210 fighter-bomber project which nearly made his company bankrupt. Nevertheless, he was certainly an innovator and was much admired by Hitler, who declared that he had "the skull of a genius", because of the Me 163 Komet rocket-powered fighter and the Me 262.At the end of the war Messerschmitt was detained by the Americans for two years. In 1952 Messerschmitt became an aviation adviser to the Spanish government, and his Bf109 was produced in Spain as the Hispano Buchon for a number of years and was powered by Rolls-Royce Merlin engines. A factory was also constructed in Egypt to produce aircraft to Messerschmitt's designs. His German company, banned from building aircraft, produced prefabricated houses, sewing machines and, from 1953 to 1962, a series of bubble-cars: the KR 175 (1953–55) and the KR 200 (1955–62) were single-cylinder three-wheeled bubble-cars, and the Tiger (1958–62) was a twin-cylinder, 500cc four-wheeler. In 1958 Messerschmitt resumed aircraft construction in Germany and later became the Honorary Chairman of the merged Messerschmitt-Bölkow-Blohm company (now part of the Franco-German Eurocopter company).[br]Further Readingvan Ishoven, 1975, Messerschmitt.

He married Elizabeth Symons in 1814, and in 1820 moved with his wife to London. He delivered a course of lectures at the Surrey Institution on the elements of chemical science, attended by, amongst others, the young Michael Faraday. While there, Gurney made his first invention, the oxyhydrogen blowpipe. For this he received the Gold Medal of the Society of Arts. He experimented with lime and magnesia for the production of an illuminant for lighthouses with some success. He invented a musical instrument of glasses played like a piano.In 1823 he started experiments related to steam and locomotion which necessitated taking a partner in to his medical practice, from which he resigned shortly after. His objective was to produce a steam-driven vehicle to run on common roads. His invention of the steam-jet of blast greatly improved the performance of the steam engine. In 1827 he took his steam carriage to Cyfarthfa at the request of Mr Crawshaw, and while there applied his steam-jet to the blast furnaces, greatly improving their performance in the manufacture of iron. Much of the success of George Stephenson's steam engine, the Rocket was due to Gurney's steam blast.In July 1829 Gurney made a historic trip with his road locomotive. This was from London to Bath and back, which was accomplished at a speed of 18 mph (29 km/h) and was made at the instigation of the Quartermaster-General of the Army. So successful was the carriage that Sir Charles Dance started to run a regular service with it between Gloucester and Cheltenham. This ran for three months without accident, until Parliament introduced prohibitive taxation on all self-propelled vehicles. A House of Commons committee proposed that these should be abolished as inhibiting progress, but this was not done. Sir Goldsworthy petitioned Parliament on the harm being done to him, but nothing was done and the coming of the railways put the matter beyond consideration. He devoted his time to finding other uses for the steam-jet: it was used for extinguishing fires in coal-mines, some of which had been burning for many years; he developed a stove for the production of gas from oil and other fatty substances, intended for lighthouses; he was responsible for the heating and the lighting of both the old and the new Houses of Parliament. His evidence after a colliery explosion resulted in an Act of Parliament requiring all mines to have two shafts. He was knighted in 1863, the same year that he suffered a stroke which incapacitated him. He retired to his house at Reeds, near Bude, where he was looked after by his daughter, Anna.[br]Principal Honours and DistinctionsKnighted 1863.

16 Caproni, Giovanni Battista (Gianni), Conte di Taliedo
SUBJECT AREA: Aerospace[br]b. 3 June 1886 Massone, Italyd. 29 October 1957 Rome, Italy[br]Italian aircraft designer and manufacturer, well known for his early large-aircraft designs.[br]Gianni Caproni studied civil and electrical engineering in Munich and Liège before moving on to Paris, where he developed an interest in aeronautics. He built his first aircraft in 1910, a biplane with a tricycle undercarriage (which has been claimed as the world's first tricycle undercarriage). Caproni and his brother, Dr Fred Caproni, set up a factory at Malpensa in northern Italy and produced a series of monoplanes and biplanes. In 1913 Caproni astounded the aviation world with his Ca 30 three-engined biplane bomber. There followed many variations, of which the most significant were the Ca 32 of 1915, the first large bomber to enter service in significant numbers, and the Ca 42 triplane of 1917 with a wing span of almost 30 metres.After the First World War, Caproni designed an even larger aircraft with three pairs of triplane wings (i.e. nine wings each of 30 metres span) and eight engines. This Ca 60 flying boat was designed to carry 100 passengers. In 1921 it made one short flight lightly loaded; however, with a load of sandbags representing sixty passengers, it crashed soon after take-off. The project was abandoned but Caproni's company prospered and expanded to become one of the largest groups of companies in Italy. In the 1930s Caproni aircraft twice broke the world altitude record. Several Caproni types were in service when Italy entered the Second World War, and an unusual research aircraft was under development. The Caproni-Campini No. 1 (CC2) was a jet, but it did not have a gas-turbine engine. Dr Campini's engine used a piston engine to drive a compressor which forced air out through a nozzle, and by burning fuel in this airstream a jet was produced. It flew with limited success in August 1940, amid much publicity: the first German jet (1939) and the first British jet (1941) were both flown in secret. Caproni retained many of his early aircraft for his private museum, including some salvaged parts from his monstrous flying boat.[br]Principal Honours and DistinctionsCreated Conte di Taliedo 1940.Further ReadingDizionario biografico degli Italiani, 1976, Vol. XIX.The Caproni Museum has published two books on the Caproni aeroplanes: Gli Aeroplani Caproni -1909–1935 and Gli Aeroplani Caproni dal 1935 in poi.

18 Branca, Giovanni de
SUBJECT AREA: Steam and internal combustion engines[br]b. 1571 Italyd. 1640 Italy[br]Italian architect who proposed what has been suggested as an early turbine, using a jet of steam to turn a wheel.[br]Branca practised architecture at Loretto. In 1629 he published Le Machine: volume nuovo et di molto artificio, in which he described various mechanisms. One was the application of rolls for working copper, lead or the precious metals gold and silver. The rolls were powered by a form of smokejack with the gases from the fire passing up a long tube forming a chimney which, through gearing, turned the rolls. Another device used a jet of steam from a boiler issuing from a mouthpiece shaped like the head of a person to impinge upon blades around the circumference of a horizontal wheel, connected through triple reduction gearing to drop stamps, for pounding drugs. This was a form of impulse turbine and has been claimed as the first machine worked by steam to do a particular operation since Heron's temple doors.[br]Further ReadingH.W.Dickinson, 1938, A Short History of the Steam Engine, Cambridge University Press (includes a description and picture of the turbine).C.Singer (ed.), 1957, A History of Technology, Vols III and IV, Oxford University Press (provides notes on Branca).RLH -
19 Laval, Carl Gustaf Patrik de
SUBJECT AREA: Agricultural and food technology, Electricity, Mechanical, pneumatic and hydraulic engineering, Steam and internal combustion engines[br]b. 9 May 1845 Orsa, Swedend. 2 February 1913 Stockholm, Sweden[br]Swedish inventor of an advanced cream separator and a steam turbine.[br]Gustaf de Laval was educated at the Stockholm Technical Institute and Uppsala University. He proved to have an unfailing vigour and variety in his inventive talent, for his interests ranged from electric lighting and electrometallurgy to aerodynamics. In the 1890s he employed over one hundred engineers to develop his inventions, but he was best known for two: the cream separator and a steam turbine. In 1877 he invented the high-speed centrifugal cream separator, which was probably the greatest advance in butter-making up to that time. By 1880 the separators were being successfully marketed all over the world, for they were quickly adopted in larger dairies where they effected enormous savings in labour and space. He followed this with various devices for the dairy industry, including a vacuum milking machine perfected in 1913. In c. 1882, de Laval invented a turbine on the principle of Hero's engine, but he quickly turned his attention to the impulse type, which was like Branca's, with a jet of steam impinging on a set of blades around the periphery of a wheel. He applied for a British patent in 1889. The steam was expanded in a single stage from the initial to the final pressure: to secure economy with the steam issuing at high velocity, the blades also had to rotate at high velocity. An early 5 hp (3.7 kW) turbine rotated at 30,000 rpm, so reduction gearing had to be introduced. Production started in Sweden in 1893 and in other countries at about the same time. In 1892 de Laval proposed employing one of his turbines of 15 hp (11 kW) in an experimental launch, but there is no evidence that it was ever actually installed in a vessel. However, his turbines were popular for powering electric generating sets for lighting textile mills and ships, and by 1900 were available in sizes up to 300 bhp (224 kW).[br]Bibliography1889, British patent no. 7,143 (steam turbine).Further ReadingT.Althin, 1943, Life of de Laval, Stockholm (a full biography).T.I.Williams (ed.), 1969, A Biographical Dictionary of Scientists, London: A. \& C.

20 Barber, John
[br]baptized 22 October 1734 Greasley, Nottinghamshire, Englandd. 6 November 1801 Attleborough, Nuneaton, England[br]English inventor of the gas turbine and jet propulsion.[br]He was the son of Francis Barber, coalmaster of Greasley, and Elizabeth Fletcher. In his will of 1765. his uncle, John Fletcher, left the bulk of his property, including collieries and Stainsby House, Horsley Woodhouse, Derbyshire, to John Barber. Another uncle, Robert, bequeathed him property in the next village, Smalley. It is clear that at this time John Barber was a man of considerable means. On a tablet erected by John in 1767, he acknowledges his debt to his uncle John in the words "in remembrance of the man who trained him up from a youth". At this time John Barber was living at Stainsby House and had already been granted his first patent, in 1766. The contents of this patent, which included a reversible water turbine, and his subsequent patents, suggest that he was very familiar with mining equipment, including the Newcomen engine. It comes as rather a surprise that c.1784 he became bankrupt and had to leave Stainsby House, evidently moving to Attleborough. In a strange twist, a descendent of Mr Sitwell, the new owner, bought the prototype Akroyd Stuart oil engine from the Doncaster Show in 1891.The second and fifth (final) patents, in 1773 and 1792, were concerned with smelting and the third, in 1776, featured a boiler-mounted impulse steam turbine. The fourth and most important patent, in 1791, describes and engine that could be applied to the "grinding of corn, flints, etc.", "rolling, slitting, forging or battering iron and other metals", "turning of mills for spinning", "turning up coals and other minerals from mines", and "stamping of ores, raising water". Further, and importantly, the directing of the fluid stream into smelting furnaces or at the stern of ships to propel them is mentioned. The engine described comprised two retorts for heating coal or oil to produce an inflammable gas, one to operate while the other was cleansed and recharged. The resultant gas, together with the right amount of air, passed to a beam-operated pump and a water-cooled combustion chamber, and then to a water-cooled nozzle to an impulse gas turbine, which drove the pumps and provided the output. A clear description of the thermodynamic sequence known as the Joule Cycle (Brayton in the USA) is thus given. Further, the method of gas production predates Murdoch's lighting of the Soho foundry by gas.It seems unlikely that John Barber was able to get his engine to work; indeed, it was well over a hundred years before a continuous combustion chamber was achieved. However, the details of the specification, for example the use of cooling water jackets and injection, suggest that considerable experimentation had taken place.To be active in the taking out of patents over a period of 26 years is remarkable; that the best came after bankruptcy is more so. There is nothing to suggest that the cost of his experiments was the cause of his financial troubles.[br]Further ReadingA.K.Bruce, 1944, "John Barber and the gas turbine", Engineer 29 December: 506–8; 8 March (1946):216, 217.C.Lyle Cummins, 1976, Internal Fire, Carnot Press.JB
