5 Champion, Nehemiah
SUBJECT AREA: Metallurgy[br]b. 1678 probably Bristol, Englandd. 9 September 1747 probably Bristol, England[br]English merchant and brass manufacturer of Bristol.[br]Several members of Champion's Quaker family were actively engaged as merchants in Bristol during the late seventeenth and the eighteenth centuries. Port records show Nehemiah in receipt of Cornish copper ore at Bristol's Crews Hole smelting works by 1706, in association with the newly formed brassworks of the city. He later became a leading partner, managing the company some time after Abraham Darby left the Bristol works to pursue his interest at Coalbrookdale. Champion, probably in company with his father, became the largest customer for Darby's Coalbrookdale products and also acted as Agent, at least briefly, for Thomas Newcomen.A patent in 1723 related to two separate innovations introduced by the brass company.The first improved the output of brass by granulating the copper constituent and increasing its surface area. A greater proportion of zinc vapour could permeate the granules compared with the previous practice, resulting in the technique being adopted generally in the cementation process used at the time. The latter part of the same patent introduced a new type of coal-fired furnace which facilitated annealing in bulk so replacing the individual processing of pieces. The principle of batch annealing was generally adopted, although the type of furnace was later improved. A further patent, in 1739, in the name of Nehemiah, concerned overshot water-wheels possibly intended for use in conjunction with the Newcomen atmospheric pumping engine employed for recycling water by his son William.Champion's two sons, John and William, and their two sons, both named John, were all concerned with production of non-ferrous metals and responsible for patented innovations. Nehemiah, shortly before his death, is believed to have partnered William at the Warmley works to exploit his son's new patent for producing metallic zinc.[br]Bibliography1723, British patent no. 454 (granulated copper technique and coal-fired furnace). 1739, British patent no. 567 (overshot water-wheels).Further ReadingA.Raistrick, 1950, Quakers in Science and Industry, London: Bannisdale Press (for the Champion family generally).J.Day, 1973, Bristol Brass, a History of the Industry, Newton Abbot: David \& Charles (for the industrial activities of Nehemiah).JD -
6 Fizeau, Armand Hippolyte Louis
SUBJECT AREA: Photography, film and optics[br]b. 23 September 1819 Paris, Franced. 18 September 1896 Nanteuil-le-Haudouin, France[br]French physicist who introduced early improvements to the daguerreotype process.[br]Fizeau's interest in photography was comparatively brief, but during this period he was at the forefront of French attempts to explore and exploit the potential of the recently announced daguerreotype process (see Daguerre). Fizeau is best remembered for his introduction in August 1840 of the practice of gold-toning daguerreotypes. This improvement not only helped protect the delicate surface of the plate from abrasion and tarnishing, but also enhanced the quality of the image. The technique was not patented and was immediately adopted by all daguerreotypists. Between 1839 and 1841, in association with Alfred Donné, Fizeau conducted experiments with the aim of converting daguerreotypes into printing plates. Prints from two of his plates were published in 1842, but the technique was never widely practised. In association with J.B.Léon Foucault, Fizeau discovered the reciprocity failure of daguerreotypes, and the same partnership produced what were probably the first daguerreotypes of the sun. Fizeau is best known in physics for making the first accurate determination of the speed of light, in 1849.[br]Further ReadingW.H.Thornthwaite, 1843, Photographic Manipulation, London (provides details of Fizeau's gold-toning process).H.Gernsheim and A.Gernsheim, 1969, The History of Photography, rev. edn, London (a more general account of Fizeau's contributions to photography).JWBiographical history of technology > Fizeau, Armand Hippolyte Louis

10 Armstrong, Edwin Howard
[br]b. 18 December 1890 New York City, New York, USAd. 31 January 1954 New York City, New York, USA[br]American engineer who invented the regenerative and superheterodyne amplifiers and frequency modulation, all major contributions to radio communication and broadcasting.[br]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.[br]Principal Honours and DistinctionsInstitution of Radio Engineers Medal of Honour 1917.
