82 Bond, George Meade
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. 17 July 1852 Newburyport, Massachusetts, USAd. 6 January 1935 Hartford, Connecticut, USA[br]American mechanical engineer and metrologist, co-developer of the Rogers- Bond Comparator.[br]After leaving school at the age of 17, George Bond taught in local schools for a few years before starting an apprenticeship in a machine shop in Grand Rapids, Michigan. He then worked as a machinist with Phoenix Furniture Company in that city until his savings permitted him to enter the Stevens Institute of Technology at Hoboken, New Jersey, in 1876. He graduated with the degree of Mechanical Engineer in 1880. In his final year he assisted William A.Rogers, Professor of Astronomy at Harvard College Observatory, Cambridge, Massachusetts, in the design of a comparator for checking standards of length. In 1880 he joined the Pratt \& Whitney Company, Hartford, Connecticut, and was Manager of the Standards and Gauge Department from then until 1902. During this period he developed cylindrical, calliper, snap, limit, thread and other gauges. He also designed the Bond Standard Measuring Machine. Bond was elected a member of the American Society of Mechanical Engineers in 1881 and of the American Society of Civil Engineers in 1887, and served on many of their committees relating to standards and units of measurement.[br]Principal Honours and DistinctionsVice-President, American Society of Mechanical Engineers 1908–10.

83 Chanute, Octave Alexandre
SUBJECT AREA: Aerospace[br]b. 18 February 1832 Paris, Franced. 24 November 1910 Chicago, USA[br]American engineer, developer of successful hang-gliders in the 1890s and disseminator of aeronautical information.[br]Chanute was born in Paris, but from the age of 6 he lived in the United States, where he became a prominent railway engineer. He developed an interest in aviation relatively late in life, and in fact built his first glider at the age of 64. Before that, he had collected all the information he could find on aviation, especially on the work of Otto Lilienthal in Germany. In 1894 he published an account of these researches in a classic work, Progress in Flying Machines.By 1896 Chanute was ready to carry out practical experiments of his own and designed a series of hang-gliders. He started with a Lilienthal-type monoplane and progressed to his very successful biplane glider. He used a bridge-truss method of cross-bracing to give his wings the required strength, a system used by many of his successors, including the Wright brothers. Chanute's gliders were flown on the shore of Lake Michigan by his two young assistants A.M.Herring and W.Avery. The biplane glider made some seven hundred flights without mishap, covering up to 100 m (110 yds). In 1898 Herring fitted an engine into a modified glider and claimed to have made two short hops.In 1900 the Wright brothers made contact with Chanute and sought his advice, which he readily gave, indeed, he became one of their most trusted advisors. In 1903 Chanute travelled to Paris and gave an illustrated lecture describing his own and the Wrights' gliding successes, generating much interest amongst European aviators.[br]Principal Honours and DistinctionsRoyal Aeronautical Society Gold Medal 1910.Bibliography1894, Progress in Flying Machines, New York (Chanute's classic work).Further ReadingC.H.Gibbs-Smith, 1986, Aviation, London.—1965, The Invention of the Aeroplane 1799–1909, London (both describe Chanute's place in the history of aviation).T.D.Crouch, A Dream of Wings, Americans and the Airplane 1875–1905 (includes several chapters on Chanute and a comprehensive bibliography).Chanute is also mentioned in most of the biographies of the Wright brothers.JDSBiographical history of technology > Chanute, Octave Alexandre

SUBJECT AREA: Medical technology[br]b. 28 August 1919 Newark, Nottinghamshire, England[br]English scientist, inventor and developer of computer-assisted tomography (CAT) scanning technique of radiographic examination.[br]After an education in Newark and London in radiocommunications and radar, Hounsfield volunteered and served in the RAF during 1939–45. He was a lecturer at Cranwell Radar School from c.1942 to 1945. From 1947 to 1951 he undertook further study in electrical and mechanical engineering, and in 1951 he joined Electrical and Musical Instruments (EMI) Ltd, where he led the design team for the first British all-transistor computer (EMIDEC, 1959). In 1969–72 he invented and developed the EMI computerized transverse axial tomography scanner system of X-ray examination; this, while applicable to other areas of the body, particularly permitted the elimination of difficulties presented since the earliest days of X-ray examination in the examination of the cranial contents.[br]Principal Honours and DistinctionsKnighted 1981.

85 Keller, Arthur
[br]b. 18 August 1901 New York City, New York, USA d. 1983[br]American engineer and developer of telephone switching equipment who was instrumental in the development of electromechanical recording and stereo techniques.[br]He obtained a BSc in electrical engineering at Cooper Union for the Advancement of Science and Art, New York, in 1923 and an MSc from Yale University, and he did postgraduate work at Columbia University. Most of the time he was also on the staff of the Bell Telephone Laboratories. The Bell Laboratories and its predecessors had a long tradition in research in speech and hearing, and in a team of researchers under H.C. Harrison, Keller developed a number of definite improvements in electrical pick-ups, gold-sputtering for matrix work and electrical disc recording equipment. From 1931 onwards the team at Bell Labs developed disc recording for moving pictures and entered into collaboration with Leopold Stokowski and the Philadelphia Orchestra concerning transmission and recording of high-fidelity sound over wires, and stereo techniques. Keller developed a stereo recording system for disc records independently of A.D. Blumlein that was used experimentally in the Bell Labs during the 1930s. During the Second World War Keller was in a team developing sonar (sound navigation and ranging) for the US Navy. After the war he concentrated on switching equipment for telephone exchanges and developed a miniature relay. In 1966 he retired from the Bell Laboratories, where he had been Director of several departments, ending as Director of the Switching Apparatus Laboratory. After retirement he was a consultant internationally, concerning electromechanical devices in particular. When, in 1980, the Bell Laboratories decided to issue LP re-recordings of a number of the experimental records made during the 1930s, Keller was brought in from retirement to supervise the project and decide on the selections.[br]BibliographyKeller was inventor or co-inventor of forty patents, including: US patent no. 2,114,471 (the principles of stereo disc recording); US patent no. 2,612,586 (tape guides with air lubrication); US patent no. 3,366,901 (a miniature crossbar switch).Apart from a large number of highly technical papers, Keller also wrote the article "Phonograph" in the 1950 and 1957 editions of Encyclopaedia Britannica.1986, Reflections of a Stereo Pioneer, San Francisco: San Francisco Press (an honest, personal account).GB-N -
86 Ricardo, Sir Harry Ralph
[br]b. 26 January 1885 London, Englandd. 18 May 1974 Graffham, Sussex, England[br]English mechanical engineer; researcher, designer and developer of internal combustion engines.[br]Harry Ricardo was the eldest child and only son of Halsey Ricardo (architect) and Catherine Rendel (daughter of Alexander Rendel, senior partner in the firm of consulting civil engineers that later became Rendel, Palmer and Tritton). He was educated at Rugby School and at Cambridge. While still at school, he designed and made a steam engine to drive his bicycle, and by the time he went up to Cambridge in 1903 he was a skilled craftsman. At Cambridge, he made a motor cycle powered by a petrol engine of his own design, and with this he won a fuel-consumption competition by covering almost 40 miles (64 km) on a quart (1.14 1) of petrol. This brought him to the attention of Professor Bertram Hopkinson, who invited him to help with research on turbulence and pre-ignition in internal combustion engines. After leaving Cambridge in 1907, he joined his grandfather's firm and became head of the design department for mechanical equipment used in civil engineering. In 1916 he was asked to help with the problem of loading tanks on to railway trucks. He was then given the task of designing and organizing the manufacture of engines for tanks, and the success of this enterprise encouraged him to set up his own establishment at Shoreham, devoted to research on, and design and development of, internal combustion engines.Leading on from the work with Hopkinson were his discoveries on the suppression of detonation in spark-ignition engines. He noted that the current paraffinic fuels were more prone to detonation than the aromatics, which were being discarded as they did not comply with the existing specifications because of their high specific gravity. He introduced the concepts of "highest useful compression ratio" (HUCR) and "toluene number" for fuel samples burned in a special variable compression-ratio engine. The toluene number was the proportion of toluene in heptane that gave the same HUCR as the fuel sample. Later, toluene was superseded by iso-octane to give the now familiar octane rating. He went on to improve the combustion in side-valve engines by increasing turbulence, shortening the flame path and minimizing the clearance between piston and head by concentrating the combustion space over the valves. By these means, the compression ratio could be increased to that used by overhead-valve engines before detonation intervened. The very hot poppet valve restricted the advancement of all internal combustion engines, so he turned his attention to eliminating it by use of the single sleeve-valve, this being developed with support from the Air Ministry. By the end of the Second World War some 130,000 such aero-engines had been built by Bristol, Napier and Rolls-Royce before the piston aero-engine was superseded by the gas turbine of Whittle. He even contributed to the success of the latter by developing a fuel control system for it.Concurrent with this was work on the diesel engine. He designed and developed the engine that halved the fuel consumption of London buses. He invented and perfected the "Comet" series of combustion chambers for diesel engines, and the Company was consulted by the vast majority of international internal combustion engine manufacturers. He published and lectured widely and fully deserved his many honours; he was elected FRS in 1929, was President of the Institution of Mechanical Engineers in 1944–5 and was knighted in 1948. This shy and modest, though very determined man was highly regarded by all who came into contact with him. It was said that research into internal combustion engines, his family and boats constituted all that he would wish from life.[br]Principal Honours and DistinctionsKnighted 1948. FRS 1929.

87 Tainter, Charles Sumner
SUBJECT AREA: Recording[br]b. 1854d. 1940[br]American scientific instrument maker, co-developer of practical cylinder recording.[br]He manufactured "philosophical devices" in Cambridge, Massachusetts, and was approached by Alexander Graham Bell in connection with the construction of toys using sound recordings. A more formal co-operation was agreed, and after Bell's receipt of the French Volta prize in 1880 he financed the Volta Laboratory Association in Washington, DC. He founded this in 1881 together with a cousin and Tainter to develop a practical sound-recording and -reproducing system. Another area that was developed was the transmission of sound by means of modulated light and reception via a selenium cell.The advances in sound recording and reproduction were very positive, and T.A. Edison was approached in mid-1885 in order to establish co-operation in the further development of a cylinder instrument. In early 1886 the Volta Graphophone Company was incorporated in Virginia, and an experimental laboratory was established in Washington, DC. The investors were connected with the secretarial services at the House of Representatives and needed the development for increasing efficiency in debate reporting. In mid-1887 Edison, against the advice of his collaborators, declined co-operation and went ahead on his own. There is no doubt that Tainter's skill in developing functional equipment and the speed with which he was able to work in the crucial years provoked other developments in the field, in particular the perfection of the Edison phonograph and the development of the disc record by Berliner.[br]BibliographyTainter's patents were numerous; those on sound recording were the most important, because they incorporated so many fundamental ideas, and included US patent no. 341, 214 (with C.A.Bell), and US patent no. 375, 579 (a complete dictation outfit).Further ReadingV.K.Chew, 1981, Talking Machines, London: Science Museum and HMSO, pp. 9–12 (provides a good overview, not only of Tainter's contribution, but also of early sound recording and reproduction).GB-NBiographical history of technology > Tainter, Charles Sumner

88 Türck, Ludwig
SUBJECT AREA: Medical technology[br]b. 22 July 1810 Vienna, Austriad. 25 February 1868 Vienna, Austria[br]Austrian neurologist, developer of the techniques of laryngoscopy.[br]The son of a wealthy jeweller, he attended medical school in Vienna and qualified in 1836. Until 1844 he was engaged in research into the anatomy and physiology of the nervous system. In 1844, while on a visit to Paris, he came to the attention of Baron Türckheim, Director of the General Hospital in Vienna. The consequence was the establishment of a special division of the hospital for nervous diseases, with Türck in charge.In 1857 he was appointed Chief Physician to the largest hospital in Vienna and at the same time he became aware of the invention in 1855 by Manuel García, a music teacher of Paris, of a practical laryngoscope. Türck adapted the apparatus to clinical purposes and proceeded to establish the diagnostic and therapeutic techniques required for its efficient use. Some conflict over priority ensued following a publication by Johann Nepomuk Czermak in 1858, but eventually a professional declaration asserted Türck's priority.[br]Bibliography1862, Recherches cliniques sur diverses maladies du larynx, de la trachée et du pharynx étudiées à l'aide du laryngoscope, Paris.Papers in Allgemein.
