87 Cinema
Portuguese cinema had its debut in June 1896 at the Royal Coliseum, Lisbon, only six months after the pioneering French cinema-makers, the brothers Lumiere, introduced the earliest motion pictures to Paris audiences. Cinema pioneers in Portugal included photographer Manuel Maria da Costa Veiga and an early enthusiast, Aurelio da Paz dos Reis. The first movie theater opened in Lisbon in 1904, and most popular were early silent shorts, including documentaries and scenes of King Carlos I swimming at Cascais beach. Beginning with the Invicta Film company in 1912 and its efforts to produce films, Portuguese cinema-makers sought technical assistance in Paris. In 1918, French film technicians from Pathé Studios of Paris came to Portugal to produce cinema. The Portuguese writer of children's books, Virginia de Castro e Almeida, hired French film and legal personnel in the 1920s under the banner of "Fortuna Film" and produced several silent films based on her compositions.In the 1930s, Portuguese cinema underwent an important advance with the work of Portuguese director-producers, including AntônioLopes Ribeiro, Manoel de Oliveira, Leitao de Barros, and Artur Duarte. They were strongly influenced by contemporary French, German, and Russian cinema, and they recruited their cinema actors from the Portuguese Theater, especially from the popular Theater of Review ( teatro de revista) of Lisbon. They included comedy radio and review stars such as Vasco Santana, Antônio Silva, Maria Matos, and Ribeirinho. As the Estado Novo regime appreciated the important potential role of film as a mode of propaganda, greater government controls and regulation followed. The first Portuguese sound film, A Severa (1928), based on a Julio Dantas book, was directed by Leitão de Barros.The next period of Portuguese cinema, the 1930s, 1940s, and much of the 1950s, has been labeled, Comédia a portuguesa, or Portuguese Comedy, as it was dominated by comedic actors from Lisbon's Theatre of Review and by such classic comedies as 1933's A Cancáo de Lisboa and similar genre such as O Pai Tirano, O Pátio das Cantigas, and A Costa do Castelo. The Portuguese film industry was extremely small and financially constrained and, until after 1970, only several films were made each year. A new era followed, the so-called "New Cinema," or Novo Cinema (ca. 1963-74), when the dictatorship collapsed. Directors of this era, influenced by France's New Wave cinema movement, were led by Fernando Lopes, Paulo Rocha, and others.After the 1974-75 Revolution, filmmakers, encouraged by new political and social freedoms, explored new themes: realism, legend, politics, and ethnography and, in the 1980s, other themes, including docufiction. Even after political liberty arrived, leaders of the cinema industry confronted familiar challenges of filmmakers everywhere: finding funds for production and audiences to purchase tickets. As the new Portugal gained more prosperity, garnered more capital, and took advantage of membership in the burgeoning European Union, Portuguese cinema benefited. Some American producers, directors, and actors, such as John Malkovich, grew enamored of residence and work in Portugal. Malkovich starred in Manoel de Oliveira's film, O Convento (The Convent), shot in Portugal, and this film gained international acclaim, if not universal critical approval. While most films viewed in the country continued to be foreign imports, especially from France, the United States, and Great Britain, recent domestic film production is larger than ever before in Portugal's cinema history: in 2005, 13 Portuguese feature films were released. One of them was coproduced with Spain, Midsummer Dream, an animated feature. That year's most acclaimed film was O Crime de Padre Amaro, based on the Eça de Queirós' novel, a film that earned a record box office return. In 2006, some 22 feature films were released. With more films made in Portugal than ever before, Portugal's cinema had entered a new era. -

SUBJECT AREA: Paper and printing[br]b. 11 May 1854 Hachtel, Germanyd. 28 October 1899 Baltimore, Maryland, USA[br]German/American inventor of the Linotype typesetting machine.[br]Mergenthaler came from a family of teachers, but following a mechanical bent he was apprenticed to a clockmaker. Having served his time, Mergenthaler emigrated to the USA in 1872 to avoid military service. He immediately secured work in Washington, DC, in the scientific instrument shop of August Hahl, the son of his former master. He steadily acquired a reputation for skill and ingenuity, and in 1876, when Hahl transferred his business to Baltimore, Mergenthaler went too. Soon after, they were commissioned to remedy the defects in a model of a writing machine devised by James O.Clephane of Washington. It produced print by typewriting, which was then multiplied by lithography. Mergenthaler soon corrected the defects and Clephane ordered a full-size version. This was completed in 1877 but did not work satisfactorily. Nevertheless, Mergenthaler was moved to engage in the long battle to mechanize the typesetting stage of the printing process. Clephane suggested substituting stereotyping for lithography in his device, but in spite of their keen efforts Mergenthaler and Hahl were again unsuccessful and they abandoned the project. In spare moments Mergenthaler continued his search for a typesetting machine. Late in 1883 it occurred to him to stamp matrices into type bars and to cast type metal into them in the same machine. From this idea, the Linotype machine developed and was completed by July 1884. It worked well and a patent was granted on 26 August that year, and Clephane and his associates set up the National Typographic Company of West Virginia to manufacture it. The New York Tribune ordered twelve Linotypes, and on 3 July 1886 the first of these set part of that day's issue. During the previous year the company had passed into the hands of a group of newspaper owners; increasing differences with the Board led to Mergenthaler's resignation in 1888, but he nevertheless continued to improve the machine, patenting over fifty modifications. The Linotype, together with the Monotype of Tolbert Lanston, rapidly supplanted earlier typesetting methods, and by the 1920s it reigned supreme, the former being used more for newspapers, the latter for book work.[br]Principal Honours and DistinctionsFranklin Institute John Scott Medal, Elliott Cresson Medal.Bibliography1898, Ottmar Mergenthaler and the Invention of Linotype, New York.Further ReadingJ.Moran, 1964, The Composition of Reading Matter, London.LRD -
89 Merica, Paul Dyer
SUBJECT AREA: Metallurgy[br]b. 17 March 1889 Warsaw, Indiana, USAd. 20 October 1957 Tarrytown, New York, USA[br]American physical metallurgist who elucidated the mechanism of the age-hardening of alloys.[br]Merica graduated from the University of Wisconsin in 1908. Before proceeding to the University of Berlin, he spent some time teaching in Wisconsin and in China. He obtained his doctorate in Berlin in 1914, and in that year he joined the US National Bureau of Standards (NBS) in Washington. During his five years there, he investigated the causes of the phenomenon of age-hardening of the important new alloy of aluminium, Duralumin.This phenomenon had been discovered not long before by Dr Alfred Wilm, a German research metallurgist. During the early years of the twentieth century, Wilm had been seeking a suitable light alloy for making cartridge cases for the Prussian government. In the autumn of 1909 he heated and quenched an aluminium alloy containing 3.5 per cent copper and 0.5 per cent magnesium and found its properties unremarkable. He happened to test it again some days later and was impressed to find its hardness and strength were much improved: Wilm had accidentally discovered age-hardening. He patented the alloy, but he made his rights over to Durener Metallwerke, who marketed it as Duralumin. This light and strong alloy was taken up by aircraft makers during the First World War, first for Zeppelins and then for other aircraft.Although age-hardened alloys found important uses, the explanation of the phenomenon eluded metallurgists until in 1919 Merica and his colleagues at the NBS gave the first rational explanation of age-hardening in light alloys. When these alloys were heated to temperatures near their melting points, the alloying constituents were taken into solution by the matrix. Quenching retained the alloying metals in supersaturated solid solution. At room temperature very small crystals of various intermetallic compounds were precipitated and, by inserting themselves in the aluminium lattice, had the effect of increasing the hardness and strength of the alloy. Merica's theory stimulated an intensive study of hardening and the mechanism that brought it about, with important consequences for the development of new alloys with special properties.In 1919 Merica joined the International Nickel Company as Director of Research, a post he held for thirty years and followed by a three-year period as President. He remained in association with the company until his death.[br]Bibliography1919, "Heat treatment and constitution of Duralumin", Sci.

90 Perkin, Sir William Henry
[br]b. 12 March 1838 London, Englandd. 14 July 1907 Sudbury, England[br]English chemist, discoverer of aniline dyes, the first synthetic dyestuffs.[br]He early showed an aptitude for chemistry and in 1853 entered the Royal College of Chemistry as a student under A.W.von Hofmann, the first Professor at the College. By the end of his first year, he had carried out his first piece of chemical research, on the action of cyanogen chloride on phenylamine, which he published in the Journal of the Chemical Society (1857). He became honorary assistant to von Hofmann in 1857; three years previously he had set up his own chemical laboratory at home, where he had discovered the first of the azo dyes, aminoazonapththalene. In 1856 Perkin began work on the synthesis of quinine by oxidizing a salt of allyl toluidine with potassium dichromate. Substituting aniline, he obtained a dark-coloured precipitate which proved to possess dyeing properties: Perkin had discovered the first aniline dye. Upon receiving favourable reports on the new material from manufacturers of dyestuffs, especially Pullars of Perth, Perkin resigned from the College and turned to the commercial exploitation of his discovery. This proved highly successful. From 1858, the dye was manufactured at his Greenford Green works as "Aniline Purple" or "Tyrian Purple". It was later to be referred to by the French as mauve. Perkin's discovery led to the development of the modern dyestuffs industry, supplanting dyes from the traditional vegetable sources. In 1869, he introduced two new methods for making the red dye alizarin, in place of the process that involved the use of the madder plant (Rubia tinctorum). In spite of German competition, he dominated the British market until the end of 1873. After eighteen years in chemical industry, Perkin retired and devoted himself entirely to the pure chemical research which he had been pursuing since the 1850s. He eventually contributed ninety papers to the Chemical Society and further papers to other bodies, including the Royal Society. For example, in 1867 he published his synthesis of unsaturated organic acids, known as "Perkin's synthesis". Other papers followed, on the structure of "Aniline Purple". In 1881 Perkin drew attention to the magnetic-rotatory power of some of the substances he had been dealing with. From then on, he devoted particular attention to the application of this phenomenon to the determination of chemical structure.Perkin won wide recognition for his discoveries and other contributions to chemistry.The half-centenary of his great discovery was celebrated in July 1906 and later that year he received a knighthood.[br]Principal Honours and DistinctionsKnighted 1906.

91 Reynolds, Richard
[br]b. 1 November 1735 Bristol, Englandd. 10 September 1816 Cheltenham, Gloucestershire, England[br]English ironmaster who invented iron rails.[br]Reynolds was born into a Quaker family, his father being an iron merchant and a considerable customer for the products of the Darbys (see Abraham Darby) of Coalbrookdale in Shropshire. After education at a Quaker boarding school in Pickwick, Wiltshire, Reynolds was apprenticed to William Fry, a grocer of Bristol, from whom he would have learned business methods. The year before the expiry of his apprenticeship in 1757, Reynolds was being sent on business errands to Coalbrookdale. In that year he met and married Hannah Darby, the daughter of Abraham Darby II. At the same time, he acquired a half-share in the Ketley ironworks, established not long before, in 1755. There he supervised not only the furnaces at Ketley and Horsehay and the foundry, but also the extension of the railway, linking this site to Coalbrookdale itself.On the death of Abraham Darby II in 1763, Reynolds took charge of the whole works during the minority of Abraham Darby III. During this period, the most notable development was the introduction by the Cranage brothers of a new way of converting pig-iron to wrought iron, a process patented in 1766 that used coal in a reverberatory furnace. This, with other processes for the same purpose, remained in use until superseded by the puddling process patented by Henry Cort in 1783 and 1784. Reynolds's most important innovation was the introduction of cast-iron rails in 1767 on the railway around Coalbrookdale. A useful network had been in operation for some time with wooden rails, but these wore out quickly and were expensive to maintain. Reynolds's iron rails were an immediate improvement, and some 20 miles (32 km) were laid within a short time. In 1768 Abraham Darby III was able to assume control of the Coalbrookdale works, but Reynolds had been extending his own interest in other ironworks and various other concerns, earning himself considerable wealth. When Darby was oppressed with loan repayments, Reynolds bought the Manor of Madely, which made him Landlord of the Coalbrookdale Company; by 1780 he was virtually banker to the company.[br]Further ReadingH.M.Rathbone, 1852, Letters of Richard Reynolds with a Memoir of his Life, London.A.Raistrick, 1989, Dynasty of Iron Founders, 2nd edn, Ironbridge Gorge Museum Trust (contains many details of Reynolds's life).LRD -
92 Sopwith, Sir Thomas (Tommy) Octave Murdoch
SUBJECT AREA: Aerospace[br]b. 18 January 1888 London, Englandd. 27 January 1989 Stockbridge, Hampshire, England[br]English aeronautical engineer and industrialist.[br]Son of a successful mining engineer, Sopwith did not shine at school and, having been turned down by the Royal Navy as a result, attended an engineering college. His first interest was motor cars and, while still in his teens, he set up a business in London with a friend in order to sell them; he also took part in races and rallies.Sopwith's interest in aviation came initially through ballooning, and in 1906 he purchased his own balloon. Four years later, inspired by the recent flights across the Channel to France and after a joy-ride at Brooklands, he bought an Avis monoplane, followed by a larger biplane, and taught himself to fly. He was awarded the Royal Aero Society's Aviator Certificate No. 31 on 21 November 1910, and he quickly distinguished himself in flying competitions on both sides of the Atlantic and started his own flying school. In his races he was ably supported by his friend Fred Sigrist, a former motor engineer. Among the people Sopwith taught to fly were an Australian, Harry Hawker, and Major Hugh Trenchard, who later became the "father" of the RAF.In 1912, depressed by the poor quality of the aircraft on trial for the British Army, Sopwith, in conjunction with Hawker and Sigrist, bought a skating rink in Kingston-upon-Thames and, assisted by Fred Sigrist, started to design and build his first aircraft, the Sopwith Hybrid. He sold this to the Royal Navy in 1913, and the following year his aviation manufacturing company became the Sopwith Aviation Company Ltd. That year a seaplane version of his Sopwith Tabloid won the Schneider Trophy in the second running of this speed competition. During 1914–18, Sopwith concentrated on producing fighters (or "scouts" as they were then called), with the Pup, the Camel, the 1½ Strutter, the Snipe and the Sopwith Triplane proving among the best in the war. He also pioneered several ideas to make flying easier for the pilot, and in 1915 he patented his adjustable tailplane and his 1 ½ Strutter was the first aircraft to be fitted with air brakes. During the four years of the First World War, Sopwith Aviation designed thirty-two different aircraft types and produced over 16,000 aircraft.The end of the First World War brought recession to the aircraft industry and in 1920 Sopwith, like many others, put his company into receivership; none the less, he immediately launched a new, smaller company with Hawker, Sigrist and V.W.Eyre, which they called the H.G. Hawker Engineering Company Ltd to avoid any confusion with the former company. He began by producing cars and motor cycles under licence, but was determined to resume aircraft production. He suffered an early blow with the death of Hawker in an air crash in 1921, but soon began supplying aircraft to the Royal Air Force again. In this he was much helped by taking on a new designer, Sydney Camm, in 1923, and during the next decade they produced a number of military aircraft types, of which the Hart light bomber and the Fury fighter, the first to exceed 200 mph (322 km/h), were the best known. In the mid-1930s Sopwith began to build a large aviation empire, acquiring first the Gloster Aircraft Company and then, in quick succession, Armstrong-Whitworth, Armstrong-Siddeley Motors Ltd and its aero-engine counterpart, and A.V.Roe, which produced Avro aircraft. Under the umbrella of the Hawker Siddeley Aircraft Company (set up in 1935) these companies produced a series of outstanding aircraft, ranging from the Hawker Hurricane, through the Avro Lancaster to the Gloster Meteor, Britain's first in-service jet aircraft, and the Hawker Typhoon, Tempest and Hunter. When Sopwith retired as Chairman of the Hawker Siddeley Group in 1963 at the age of 75, a prototype jump-jet (the P-1127) was being tested, later to become the Harrier, a for cry from the fragile biplanes of 1910.Sopwith also had a passion for yachting and came close to wresting the America's Cup from the USA in 1934 when sailing his yacht Endeavour, which incorporated a number of features years ahead of their time; his greatest regret was that he failed in his attempts to win this famous yachting trophy for Britain. After his retirement as Chairman of the Hawker Siddeley Group, he remained on the Board until 1978. The British aviation industry had been nationalized in April 1977, and Hawker Siddeley's aircraft interests merged with the British Aircraft Corporation to become British Aerospace (BAe). Nevertheless, by then the Group had built up a wide range of companies in the field of mechanical and electrical engineering, and its board conferred on Sopwith the title Founder and Life President.[br]Principal Honours and DistinctionsKnighted 1953.

97 Baxter, George
SUBJECT AREA: Paper and printing[br]b. 31 July 1804 Lewes, Sussex, Englandd. 11 January 1867 Sydenham, London, England[br]English pioneer in colour printing.[br]The son of a printer, Baxter was apprenticed to a wood engraver and there began his search for improved methods of making coloured prints, hitherto the perquisite of the rich, in order to bring them within reach of a wider public. After marriage to the daughter of Robert Harrild, founder of the printing firm of Harrild \& Co., he set up house in London, where he continued his experiments on colour while maintaining the run-of-the-mill work that kept the family.The nineteenth century saw a tremendous advance in methods of printing pictures, produced as separate prints or as book illustrations. For the first three decades colour was supplied by hand, but from the 1830s attempts were made to print in colour, using a separate plate for each one. Coloured prints were produced by chromolithography and relief printing on a small scale. Prints were first made with the latter method on a commercial scale by Baxter with a process that he patented in 1835. He generally used a key plate that was engraved, aquatinted or lithographed; the colours were then printed separately from wood or metal blocks. Baxter was a skilful printer and his work reached a high standard. An early example is the frontispiece to Robert Mudie's Summer (1837). In 1849 he began licensing his patent to other printers, and after the Great Exhibition of 1851 colour relief printing came into its own. Of the plethora of illustrated literature that appeared then, Baxter's Gems of the Great Exhibition was one of the most widely circulated souvenirs of the event.Baxter remained an active printer through the 1850s, but increasing competition from the German coloured lithographic process undermined his business and in 1860 he gave up the unequal struggle. In May of that year, all his oil pictures, engravings and blocks went up for auction, some 3,000 lots altogether. Baxter retired to Sydenham, then a country place, making occasional visits to London until injuries sustained in a mishap while he was ascending a London omnibus led to his death. Above all, he helped to initiate the change from the black and white world of pre-Victorian literature to the riotously colourful world of today.[br]Further ReadingC.T.Courtney Lewis, 1908, George Baxter, the Picture Printer, London: Sampson Lowe, Marsden (the classic account).M.E.Mitzmann, 1978, George Baxter and the Baxter Prints, Newton Abbot: David \& Charles.LRD -
98 Bessemer, Sir Henry
SUBJECT AREA: Metallurgy[br]b. 19 January 1813 Charlton (near Hitchin), Hertfordshire, Englandd. 15 January 1898 Denmark Hill, London, England[br]English inventor of the Bessemer steelmaking process.[br]The most valuable part of Bessemer's education took place in the workshop of his inventor father. At the age of only 17 he went to London to seek his fortune and set himself up in the trade of casting art works in white metal. He went on to the embossing of metals and other materials and this led to his first major invention, whereby a date was incorporated in the die for embossing seals, thus preventing the wholesale forgeries that had previously been committed. For this, a grateful Government promised Bessemer a paid position, a promise that was never kept; recognition came only in 1879 with a belated knighthood. Bessemer turned to other inventions, mainly in metalworking, including a process for making bronze powder and gold paint. After he had overcome technical problems, the process became highly profitable, earning him a considerable income during the forty years it was in use.The Crimean War presented inventors such as Bessemer with a challenge when weaknesses in the iron used to make the cannon became apparent. In 1856, at his Baxter House premises in St Paneras, London, he tried fusing cast iron with steel. Noticing the effect of an air current on the molten mixture, he constructed a reaction vessel or converter in which air was blown through molten cast iron. There was a vigorous reaction which nearly burned the house down, and Bessemer found the iron to be almost completely decarburized, without the slag threads always present in wrought iron. Bessemer had in fact invented not only a new process but a new material, mild steel. His paper "On the manufacture of malleable iron and steel without fuel" at the British Association meeting in Cheltenham later that year created a stir. Bessemer was courted by ironmasters to license the process. However, success was short-lived, for they found that phosphorus in the original iron ore passed into the metal and rendered it useless. By chance, Bessemer had used in his trials pig-iron, derived from haematite, a phosphorus-free ore. Bessemer tried hard to overcome the problem, but lacking chemical knowledge he resigned himself to limiting his process to this kind of pig-iron. This limitation was removed in 1879 by Sidney Gilchrist Thomas, who substituted a chemically basic lining in the converter in place of the acid lining used by Bessemer. This reacted with the phosphorus to form a substance that could be tapped off with the slag, leaving the steel free from this harmful element. Even so, the new material had begun to be applied in engineering, especially for railways. The open-hearth process developed by Siemens and the Martin brothers complemented rather than competed with Bessemer steel. The widespread use of the two processes had a revolutionary effect on mechanical and structural engineering and earned Bessemer around £1 million in royalties before the patents expired.[br]Principal Honours and DistinctionsKnighted 1879.

99 Fulton, Robert
SUBJECT AREA: Ports and shipping[br]b. 14 November 1765 Lancaster, Pennsylvania, USAd. 24 February 1815 New York, USA[br]American pioneer of steamships and of North American steam navigation.[br]The early life of Fulton is documented sparsely; however, it is clear that he was brought up in poor circumstances along with three sisters and one brother by a widowed mother. The War of Independence was raging around them for some years, but despite this it is believed that he spent some time learning the jeweller's trade in Philadelphia and had by then made a name for himself as a miniaturist. Throughout his life he remained skilled with his hands and well able to record technical detail on paper. He witnessed many of the early trials of American steamboats and saw the work of William Henry and John Fitch, and in 1787 he set off for the first time to Europe. For some years he examined steamships in Paris and without doubt saw the Charlotte Dundas on the Forth and Clyde Canal near Glasgow. In 1803 he built a steamship that ran on the Seine at 4 1/2 mph (7.25 km/h), and when it was lost, another to replace it. All his designs were based on principles that had been tried and proved elsewhere, and in this respect he was more of a developer than an inventor. After some time experimenting with submersibles and torpedoes for the British and French governments, in 1806 he returned to the United States. In 1807 he took delivery of the 100 ton displacement paddle steamer Clermont from the yard of Charles Browne of East River, New York. In August of that year it started the passenger services on the Hudson River and this can be claimed as the commencement of world passenger steam navigation. Again the ship was traditional in shape and the machinery was supplied by Messrs Boulton and Watt. This was followed by other ships, including Car of Neptune, Paragon and the world's first steam warship, Demolgos, launched in New York in October 1814 and designed by Fulton for coastal defence and the breaking of the British blockade. His last and finest boat was named Chancellor Livingston after his friend and patron Robert Livingston (1746–1813); the timber hull was launched in 1816, some months after Fulton's death.[br]Further ReadingH.P.Spratt, 1958, The Birth of the Steamboat, London: Griffin.

100 Merritt, William Hamilton
[br]b. 3 July 1793 Bedford, Winchester County, New York, USAd. 5 July 1862 aboard a vessel on the Cornwall Canal, Canada[br]American-born Canadian merchant, entrepreneur and promoter of the First and Second Welland Canals bypassing the Niagara Falls and linking Lakes Ontario and Erie.[br]Although he was born in the USA, his family moved to Canada in 1796. Educated in St Catharines and Niagara, he received a good training in mathematics, navigation and surveying. He served with distinction in the 1812–14 war, although he was captured by the Americans in 1814. After the war he established himself in business operating a sawmill, a flour mill, a small distillery, a potashery, a cooperage and a smithy, as well as running a general store. By 1818 he was one of the leading figures in the area and realized that for real economic progress it was essential to improve communications in the Niagara peninsula; in that year he surveyed a route for a waterway that would carry boats.In c. 1820 he began discussions with neighbouring landowners and businessmen, who, on 19 January 1824 together obtained a charter for building the first Welland Canal to link Lakes Ontario and Erie. They were greatly influenced by the realization that the completion of the Erie Canal would attract trade through the United States instead of through Canada. Construction began on 30 November 1824, largely with redundant labour from the Erie Canal. Merritt foresaw the need for financial support and for publicity to sustain interest in the project. Accordingly he started a newspaper, the Farmer's Journal and Welland Canal Intelligencer, which was published until 1835. He also visited York (now Toronto), the capital of Upper Canada, and obtained some support, but the Government was reluctant to assist financially. He was more successful in raising money in New York. Then in 1828 he visited England to see Telford and persuaded both Telford and the Duke of Wellington, among others, to purchase shares. The Canal opened on 30 November 1829. In 1832 Merritt became a member of the Legislative Assembly of Upper Canada, and after the Union of the Canadas in 1841 he was elected to the new Assembly, later serving as Minister of Public Works and then as President of the Assembly. He advocated improvements to the St Lawrence River and also promoted railways. He pioneered a bridge across the Niagara River that was opened in 1849 and later carried a railway. He was not a canal engineer, but he did pioneer communications in developing territory.[br]Further ReadingR.M.Styran and R.R.Taylor, 1988, The Welland Canals.
