86 Generation of 1870
A generation of Portuguese writers and intellectuals and a postregeneration phase of the country's intellectual history in the last third of the 19th century. Many of them graduates of Coimbra University, these writers, whose work challenged conventional wisdom of their day, included J. Oliveira Martins, economist and social scientist; Eça de Queirós, novelist; Antero de Quental, poet; Ramalho Ortigão, editor and essayist; Teófilo Braga, literary historian; and the geographer and diplomat abroad, Jaime Batalha Reis. Coming of political age at the time of the Franco-Prussian War, the French Commune, and the French Third Republic (1870-71), these Portuguese intellectuals believed that economically weak Portugal had a polity and society in the grip of a pervasive decadence and inertia. They called for reform and renewal.Critical of romanticism, they were realists and neorealists and espoused the ideas of Karl Marx, Pierre Proudhon, and Auguste Comte. They called for revolution through the establishment of republicanism and socialism, and they were convinced that Portugal's backwardness and poverty were due primarily to the ancient influences of a weakened monarchy and the Catholic Church. This group of like-minded but also distinctive thinkers had an important impact on Portuguese letters and elite culture, but only a minor effect on contemporary politics and government.Like so many other movements in modern Portugal, the Generation of 1870's initiatives began as essentially a protest by university students of Coimbra, who confronted the status quo and sought to change their world by means of change and innovation in action and ideas. In certain respects, Portugal's Generation of 1870 resembled neighboring Spain's Generation of 1898, which began its "rebellion" in ideas following a disastrous foreign war (the Spanish-American War, 1898). -
87 Jerónimos, Monastery of
(Mosteiro do Jerónimos)Located at Belém, west of Lisbon, the Monastery and Cathedral of Jerônimos is the most magnificent of the Age of Discoveries monuments. Ordered built as a gift to the monastic Order of Hieronymites by King Manuel I ( 1469- 1521), following the return of Vasco da Gama from India in 1499, Jerónimos was constructed between 1502 and 1525. The purpose of this massive building was to commemorate the Portuguese discovery of the sea route to India. Its location, at the time of its building very close to the water, was near the Restelo beach, the departure point for da Gama's voyage.One of Portugal's premier tourist attractions, Jerónimos consists of a church and claustrum and a portion of the convent, partially destroyed in the 1755 Lisbon earthquake. The Manueline architectural style was an innovation (named for King Manuel I, who helped finance constructions from the new imperial wealth from Africa and Asia; more recently, students employ the term Atlantic Baroque), with columns, pillars, and door frames decorated elaborately with stone sculpted in the form of maritime objects such as ship ropes, coral, sea life, sailors, and seaweeds.Jerónimos is inland from the Monument of the Discoveries, in an open square once the main site of the 1940 Double Centenary Exposition of the Portuguese World, a kind of Lisbon world's fair. -

SUBJECT AREA: Photography, film and optics[br]b. 24 July 1843 Englandd. 2 December 1920 England[br]English photographic scientist, inventor and author.[br]Abney began his career as an officer in the Army and was an instructor in chemistry in the Royal Engineers at Chatham, where he made substantial use of photography as a working tool. He retired from the Army in 1877 and joined the Science and Art Department at South Kensington. It was at Abney's suggestion that a collection of photographic equipment and processes was established in the South Kensington Museum (later to become the Science Museum Photography Collection).Abney undertook significant researches into the nature of gelatine silver halide emulsions at a time when they were being widely adopted by photographers. Perhaps his most important practical innovations were the introduction of hydroquinone as a developing agent in 1880 and silver gelatine citrochloride emulsions for printing-out paper (POP) in 1882. However, Abney was at the forefront of many aspects of photographic research during a period of great innovation and change in photography. He devised new techniques of photomechanical printing and conducted significant researches in the fields of photochemistry and spectral analysis. Abney published throughout his career for both the specialist scientist and the more general photographic practitioner.[br]Principal Honours and DistinctionsKCB 1900. FRS 1877.

92 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.

93 Bedson, George
SUBJECT AREA: Metallurgy[br]b. 3 November 1820 Sutton Coldfield, Warwickshire, Englandd. 12 December 1884 Manchester (?), England[br]English metallurgist, inventor of the continuous rolling mill.[br]He acquired a considerable knowledge of wire-making in his father's works before he took a position in 1839 at the works of James Edleston at Warrington. From there, in 1851, he went to Manchester as Manager of Richard Johnson \& Sons' wire mill, where he remained for the rest of his life. It was there that he initiated several important improvements in the manufacture of wire. These included a system of circulating puddling furnace water bottoms and sides, and a galvanizing process. His most important innovation, however, was the continuous mill for producing iron rod for wiredrawing. Previously the red-hot iron billets had to be handled repeatedly through a stand or set of rolls to reduce the billet to the required shape, with time and heat being lost at each handling. In Bedson's continuous mill, the billet entered the first of a succession of stands placed as closely to each other as possible and emerged from the final one as rod suitable for wiredrawing, without any intermediate handling. A second novel feature was that alternate rolls were arranged vertically to save turning the piece manually through a right angle. That improved the quality as well as the speed of production. Bedson's first continuous mill was erected in Manchester in 1862 and had sixteen stands in tandem. A mill on this principle had been patented the previous year by Charles While of Pontypridd, South Wales, but it was Bedson who made it work and brought it into use commercially. A difficult problem to overcome was that as the piece being rolled lengthened, its speed increased, so that each pair of rolls had to increase correspondingly. The only source of power was a steam engine working a single drive shaft, but Bedson achieved the greater speeds by using successively larger gear-wheels at each stand.Bedson's first mill was highly successful, and a second one was erected at the Manchester works; however, its application was limited to the production of small bars, rods and sections. Nevertheless, Bedson's mill established an important principle of rolling-mill design that was to have wider applications in later years.[br]Further ReadingObituary, 1884, Journal of the Iron and Steel Institute 27:539–40.

94 Bramah, Joseph
SUBJECT AREA: Civil engineering, Domestic appliances and interiors, Land transport, Mechanical, pneumatic and hydraulic engineering, Public utilities[br]b. 2 April 1749 Stainborough, Yorkshire, Englandd. 9 December 1814 Pimlico, London, England[br]English inventor of the second patented water-closet, the beer-engine, the Bramah lock and, most important, the hydraulic press.[br]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.[br]Bibliography1778, British patent no. 1177 (water-closet). 1784, British patent no. 1430 (Bramah Lock). 1795, British patent no. 2045 (hydraulic press). 1809, British patent no. 3260 (fountain pen). 1812, British patent no. 3611.Further ReadingI.McNeil, 1968, Joseph Bramah, a Century of Invention.S.Smiles, 1863, Industrial Biography.H.W.Dickinson, 1942, "Joseph Bramah and his inventions", Transactions of the Newcomen Society 22:169–86.IMcN -

SUBJECT AREA: Agricultural and food technology[br]b. 1861 USAd. 1943 USA[br]African-American agriculturalist.[br]In 1896 Carver was invited by Booker T.Washington, noted for his efforts to improve the education of African American craftspeople after the Civil War, to join the teaching staff at the Tuskegee Institute, Alabama. Carver became renowned for his innovative work in developing agricultural products, particularly from the peanut, sweet potato and cowpea. He was one of the first agriculturalists of that time to promote the use of organic fertilizers, and he was noted for his work in the hybridization of local plants. In spite of these achievements, his immediate impact on the African American farming community lay in promoting agricultural education and extension work. In 1897 Carver was appointed the first director of the Tuskegee agricultural experiment station. Here, he developed teaching techniques in agricultural education, such as issuing a series of clearly-written information bulletins. He also devised the first mobile school in the American South, which consisted of a farm wagon equipped with educational material and travelled from farm to farm, demonstrating the latest agricultural techniques.Carver was granted only three patents: one in 1923 for a cosmetic and two, in 1925 and 1927, for processes for making pigments.[br]Further ReadingP.P.James, 1989, The Real McCoy: African American Invention and Innovation 2619– 1930, Washington, DC: Smithsonian Institution Press, 69–70.LRDBiographical history of technology > Carver, George Washington

96 Clerke, Sir Clement
SUBJECT AREA: Metallurgy[br]d. 1693[br]English entrepreneur responsible, with others, for attempts to introduce coal-fired smelting of lead and, later, of copper.[br]Clerke, from Launde Abbey in Leicestershire, was involved in early experiments to smelt lead using coal fuel, which was believed to have been located on the Leicestershire-Derbyshire border. Concurrently, Lord Grandison was financing experiments at Bristol for similar purposes, causing the downfall of an earlier unsuccessful patented method before securing his own patent in 1678. In that same year Clerke took over management of the Bristol works, claiming the ability to secure financial return from Grandison's methods. Financial success proved elusive, although the technical problems of adapting the reverberatory furnace to coal fuel appear to have been solved when Clerke was found to have established another lead works nearby on his own account. He was forced to cease work on lead in 1684 in respect of Grandison's patent rights. Clerke then turned to investigations into the coal-fired smelting of other metals and started to smelt copper in coal-fired reverberatory furnaces. By 1688–9 small supplied of merchantable copper were offered for sale in London in order to pay his workers, possibly because of further financial troubles. The practical success of his smelting innovation is widely acknowledged to have been the responsibility of John Coster and, to a smaller extent, Gabriel Wayne, both of whom left Clerke and set up separate works elsewhere. Clerke's son Talbot took over administration of his father's works, which declined still further and closed c. 1693, at about the time of Sir Clement's death. Both Coster and Wayne continued to develop smelting techniques, establishing a new British industry in the smelting of copper with coal.[br]Principal Honours and DistinctionsCreated baronet 1661.Further ReadingRhys Jenkins, 1934, "The reverberatory furnace with coal fuel", Transactions of the Newcomen Society 34:67–81.—1943–4, "Copper smelting in England: Revival at the end of the seventeenth century", Transactions of the Newcomen Society 24:78–80.J.Morton, 1985, The Rise of the Modern Copper and Brass Industry: 1690 to 1750, unpublished PhD thesis, University of Birmingham, 87–106.JD -
97 Issigonis, Sir Alexander Arnold Constantine (Alec)
[br]b. 18 November 1906 Smyrna (now Izmir), Turkeyd. 2 October 1988 Birmingham, England[br]British automobile designer whose work included the Morris Minor and the Mini series.[br]His father was of Greek descent but was a naturalized British subject in Turkey who ran a marine engineering business. After the First World War, the British in Turkey were evacuated by the Royal Navy, the Issigonis family among them. His father died en route in Malta, but the rest of the family arrived in England in 1922. Alec studied engineering at Battersea Polytechnic for three years and in 1928 was employed as a draughtsman by a firm of consulting engineers in Victoria Street who were working on a form of automatic transmission. He had occasion to travel frequently in the Midlands at this time and visited many factories in the automobile industry. He was offered a job in the drawing office at Humber and lived for a couple of years in Kenilworth. While there he met Robert Boyle, Chief Engineer of Morris Motors (see Morris, William Richard), who offered him a job at Cowley. There he worked at first on the design of independent front suspension. At Morris Motors, he designed the Morris Minor, which entered production in 1948 and continued to be manufactured until 1971. Issigonis disliked mergers, and after the merger of Morris with Austin to form the British Motor Corporation (BMC) he left to join Alvis in 1952. The car he designed there, a V8 saloon, was built as a prototype but was never put into production. Following his return to BMC to become Technical Director in 1955, his most celebrated design was the Mini series, which entered production in 1959. This was a radically new concept: it was unique for its combination of a transversely mounted engine in unit with the gearbox, front wheel drive and rubber suspension system. This suspension system, designed in cooperation with Alex Moulton, was also a fundamental innovation, developed from the system designed by Moulton for the earlier Alvis prototype. Issigonis remained as Technical Director of BMC until his retirement.[br]Further ReadingPeter King, 1989, The Motor Men.

98 Le Gray, Gustave
SUBJECT AREA: Photography, film and optics[br]b. 1820 Villiers-le-Bel, Franced. 1882 Cairo, Egypt[br]French painter and photographic innovator.[br]Le Gray studied painting, and to supplement his income as an artist he took up photography in the mid-1840s. He showed remarkable aptitude, and for a time he was at the forefront of innovation in France and pioneered a number of minor improvements. In 1847 he began gold-toning positive-paper prints, a practice widely adopted later. In 1850 independently of Archer in England, he experimented with collodion on glass as a carrying medium for silver salts. It was also in 1850 that Le Gray introduced his waxed-paper process, an improvement of Talbot's calotype process which was favoured by many travelling photographers in the 1850s and 1860s. Le Gray published instruction manuals in photography that were well received. He travelled to Egypt to teach drawing in 1865, but his health deteriorated after a riding accident and he made no further significant contributions to photography.[br]Bibliography1850, Traité pratique de photographier sur papier et sur verre, Paris 1851, 2nd edn, London: T. \& R.Willats (his most significant publication).Further ReadingJ.M.Eder, 1945, History of Photography, trans.

99 Matzeliger, Jan
SUBJECT AREA: Domestic appliances and interiors[br]b. 1852 Surinamd. 1889 Lynn, Massachusetts, (?) USA[br]African-American inventor of the shoe-lasting machine.[br]He served an apprenticeship as a machinist in his native country, Surinam. As a young man he emigrated to New England in the USA, but he was unable to secure employment in his trade. To survive, he took various odd jobs, including sewing soles on to shoes in a factory at Lynn, Massachusetts, a centre of the shoemaking industry. Much of the shoemaking process had already been mechanized, but lasting remained laborious, painstaking hand work. Matzeliger turned his undoubted inventive powers to mechanizing this operation. It took him four years to achieve a working model of a mechanical last that could be patented. By this time his health and finances had been undermined by the struggle to reach this stage; to raise funds he had to dispose of two-thirds of his rights in his patent to two local investors. Eventually he demonstrated a trial model of his lasting machine and successfully lasted seventy-five pairs of shoes. Not satisfied with that, Matzeliger went on to produce two improved machines, protected by further patents. Finally, the United Shoe Machine Company bought up his patents, but that relief came too late to prevent Matzeliger from dying in poor circumstances. The mechanization of shoe lasting made a significant contribution to the manufacture of shoes, raising production and reducing costs. It also effectively extinguished the final element of skilled hand work required in shoemaking, earning him considerable unpopularity among the workers who were about to be displaced, and resulting in the machine being derogatorily nicknamed "Niggerhead".[br]Further ReadingP.P.James, 1989, The Real McCoy: African-American Invention and Innovation 1619– 1930, Washington, DC: Smithsonian Institution, pp. 70–2.LRD -
100 Monro, Philip Peter
SUBJECT AREA: Chemical technology[br]b. 27 May 1946 London, England[br]English biologist, inventor of a water-purification process by osmosis.[br]Monro's whole family background is engineering, an interest he did not share. Instead, he preferred biology, an enthusiasm aroused by reading the celebrated Science of Life by H.G. and G.P.Wells and Julian Huxley. Educated at a London comprehensive school, Monro found it necessary to attend evening classes while at school to take his advanced level science examinations. Lacking parental support, he could not pursue a degree course until he was 21 years old, and so he gained valuable practical experience as a research technician. He resumed his studies and took a zoology degree at Portsmouth Polytechnic. He then worked in a range of zoology and medical laboratories, culminating after twelve years as a Senior Experimental Officer at Southampton Medical School. In 1989 he relinquished his post to devote himself fall time to developing his inventions as Managing Director of Hampshire Advisory and Technical Services Ltd (HATS). Also in 1988 he obtained his PhD from Southampton University, in the field of embryology.Monro had meanwhile been demonstrating a talent for invention, mainly in microscopy. His most important invention, however, is of a water-purification system. The idea for it came from Michael Wilson of the Institute of Dental Surgery in London, who evolved a technique for osmotic production of sterile oral rehydration solutions, of particular use in treating infants suffering from diarrhoea in third-world countries. Monro broadened the original concept to include dried food, intravenous solutions and even dried blood. The process uses simple equipment and no external power and works as follows: a dry sugar/salts mixture is sealed in one compartment of a double bag, the common wall of which is a semipermeable membrane. Impure water is placed in the empty compartment and the water transfers across the membrane by the osmotic force of the sugar/salts. As the pores in the membrane exclude all viruses, bacteria and their toxins, a sterile solution is produced.With the help of a research fellowship granted for humanitarian reasons at King Alfred College, Winchester, the invention was developed to functional prototype stage in 1993, with worldwide patent protection. Commercial production was expected to follow, if sufficient financial backing were forthcoming. The process is not intended to replace large installations, but will revolutionize the small-scale production of sterile water in scattered third-world communities and in disaster areas where normal services have been disrupted.HATS was awarded First Prize in the small business category and was overall prize winner in the Toshiba Year of Invention, received a NatWest/BP award for technology and a Prince of Wales Award for Innovation.[br]Bibliography1993, with M.Wilson and W.A.M.Cutting, "Osmotic production of sterile oral rehydration solutions", Tropical Doctor 23:69–72.LRD
