10 Praed, William
SUBJECT AREA: Canals[br]b. 24 June 1747 Trevethoe, Leland, St Ives, Cornwall, Englandd. 9 October 1833 Trevethoe, Leland, St Ives, Cornwall, England[br]English banker and Member of Parliament.[br]Born into a wealthy Cornish family, he was educated at Eton and Magdalen College, Oxford. He was elected Member of Parliament for St Ives in 1774, but it was alleged that his father, who was a banker, had acted as agent for both his son and Drummond, the other candidate for the same party, in the course of which he advanced money to voters "on their notes payable with interest to the bank of Truro (Praed's bank)" but with the understanding that repayment would not be demanded from those who had voted for Praed and Drummond. Praed's election was therefore declared void on 8 May 1775. He was re-elected in 1780, by which time St Ives was virtually a Praed family monopoly. He served in successive Parliaments until 1806 and then represented Banbury until 1808. Meanwhile, in 1779 he had become a partner in his father's Truro bank, c. 1801 founded the London bank of Praed \& Co. at 189 Fleet Street.While in Parliament, he was instrumental in obtaining and carrying into effect the Bill for the Grand Junction Canal from Braunston to London. He was elected Chairman of the company formed for constructing the canal and proved an excellent choice, serving the company faithfully for nearly thirty years until his resignation in 1821. Upon his marriage to Elizabeth Tyringham in 1778 he made his home at Tyringham Hall in Buckinghamshire and so was very much in the Grand Junction Canal Company's area. London's Praed Street, in which Paddington Station stands, is named in his honour and the canal basin is at the rear of this street. His monument in Tyringham Church bears a relief illustrating a pair of lock gates and a canal boat.[br]Further ReadingAlan H.Faulkner, 1972, The Grand Junction Canal, Newton Abbot: David \& Charles.

11 Bickford, William
SUBJECT AREA: Mining and extraction technology[br]b. 1774 Devonshire, Englandd. 1834 Tuckingmill, Cornwall, England[br]English leather merchant, inventor of the safety fuse.[br]Having tried in vain to make his living as a currier in Truro, Cornwall, he set up as a leather merchant in Tuckingmill and became aware of the high casualty rates suffered by local tin-miners in shot-firing accidents. He therefore started attempts to discover a safe means of igniting charges, and came up with a form of safety fuse that made the operation of blasting much less hazardous. It was patented in 1831 and consisted of a cable of jute and string containing a thin core of powder; it provided a dependable means for conveying the flame to the charge so that the danger of hang fires was almost eliminated. Its accurate and consistent timing allowed the firing of several holes at a time without the fusing of the last being destroyed by the blast from the first. By 1840, a gutta-percha fuse had been developed which could be used in wet conditions and was an improvement until the use of dynamite for shot-firing.Accounts of the invention, after it had been described in the Report from the Select Committee on Accidents in Mines (1835, London) were widespread in various foreign mining journals, and in the 1840s factories were set up in different mining areas on the European continent, in America and in Australia. Bickford himself founded a firm at Tuckingmill in the year that he came up with his invention which was later controlled by his descendants until it finally merged with Imperial Chemical Industries (ICI) after the First World War.[br]Further ReadingF.Heise, 1904, Sprengstoffe und Zündung der Sprengschüsse, Berlin (provides a detailed description of the development).W.J.Reader, 1970, Imperial Chemical Industries.

12 Davy, Sir Humphry
[br]b. 17 December 1778 Penzance, Cornwall, Englandd. 29 May 1829 Geneva, Switzerland[br]English chemist, discoverer of the alkali and alkaline earth metals and the halogens, inventor of the miner's safety lamp.[br]Educated at the Latin School at Penzance and from 1792 at Truro Grammar School, Davy was apprenticed to a surgeon in Penzance. In 1797 he began to teach himself chemistry by reading, among other works, Lavoisier's elementary treatise on chemistry. In 1798 Dr Thomas Beddoes of Bristol engaged him as assistant in setting up his Pneumatic Institution to pioneer the medical application of the newly discovered gases, especially oxygen.In 1799 he discovered the anaesthetic properties of nitrous oxide, discovered not long before by the chemist Joseph Priestley. He also noted its intoxicating qualities, on account of which it was dubbed "laughing-gas". Two years later Count Rumford, founder of the Royal Institution in 1800, appointed Davy Assistant Lecturer, and the following year Professor. His lecturing ability soon began to attract large audiences, making science both popular and fashionable.Davy was stimulated by Volta's invention of the voltaic pile, or electric battery, to construct one for himself in 1800. That enabled him to embark on the researches into electrochemistry by which is chiefly known. In 1807 he tried decomposing caustic soda and caustic potash, hitherto regarded as elements, by electrolysis and obtained the metals sodium and potassium. He went on to discover the metals barium, strontium, calcium and magnesium by the same means. Next, he turned his attention to chlorine, which was then regarded as an oxide in accordance with Lavoisier's theory that oxygen was the essential component of acids; Davy failed to decompose it, however, even with the aid of electricity and concluded that it was an element, thus disproving Lavoisier's view of the nature of acids. In 1812 Davy published his Elements of Chemical Philosophy, in which he presented his chemical ideas without, however, committing himself to the atomic theory, recently advanced by John Dalton.In 1813 Davy engaged Faraday as Assistant, perhaps his greatest service to science. In April 1815 Davy was asked to assist in the development of a miner's lamp which could be safely used in a firedamp (methane) laden atmosphere. The "Davy lamp", which emerged in January 1816, had its flame completely surrounded by a fine wire mesh; George Stephenson's lamp, based on a similar principle, had been introduced into the Northumberland pits several months earlier, and a bitter controversy as to priority of invention ensued, but it was Davy who was awarded the prize for inventing a successful safety lamp.In 1824 Davy was the first to suggest the possibility of conferring cathodic protection to the copper bottoms of naval vessels by the use of sacrificial electrodes. Zinc and iron were found to be equally effective in inhibiting corrosion, although the scheme was later abandoned when it was found that ships protected in this way were rapidly fouled by weeds and barnacles.[br]Principal Honours and DistinctionsKnighted 1812.

13 Edwards, Humphrey
SUBJECT AREA: Steam and internal combustion engines[br]fl. c.1808–25 London (?), Englandd. after 1825 France (?)[br]English co-developer of Woolf s compound steam engine.[br]When Arthur Woolf left the Griffin Brewery, London, in October 1808, he formed a partnership with Humphrey Edwards, described as a millwright at Mill Street, Lambeth, where they started an engine works to build Woolf's type of compound engine. A number of small engines were constructed and other ordinary engines modified with the addition of a high-pressure cylinder. Improvements were made in each succeeding engine, and by 1811 a standard form had been evolved. During this experimental period, engines were made with cylinders side by side as well as the more usual layout with one behind the other. The valve gear and other details were also improved. Steam pressure may have been around 40 psi (2.8 kg/cm2). In an advertisement of February 1811, the partners claimed that their engines had been brought to such a state of perfection that they consumed only half the quantity of coal required for engines on the plan of Messrs Boulton \& Watt. Woolf visited Cornwall, where he realized that more potential for his engines lay there than in London; in May 1811 the partnership was dissolved, with Woolf returning to his home county. Edwards struggled on alone in London for a while, but when he saw a more promising future for the engine in France he moved to Paris. On 25 May 1815 he obtained a French patent, a Brevet d'importation, for ten years. A report in 1817 shows that during the previous two years he had imported into France fifteen engines of different sizes which were at work in eight places in various parts of the country. He licensed a mining company in the north of France to make twenty-five engines for winding coal. In France there was always much more interest in rotative engines than pumping ones. Edwards may have formed a partnership with Goupil \& Cie, Dampierre, to build engines, but this is uncertain. He became a member of the firm Scipion, Perrier, Edwards \& Chappert, which took over the Chaillot Foundry of the Perrier Frères in Paris, and it seems that Edwards continued to build steam engines there for the rest of his life. In 1824 it was claimed that he had made about 100 engines in England and another 200 in France, but this is probably an exaggeration.The Woolf engine acquired its popularity in France because its compound design was more economical than the single-cylinder type. To enable it to be operated safely, Edwards first modified Woolf s cast-iron boiler in 1815 by placing two small drums over the fire, and then in 1825 replaced the cast iron with wrought iron. The modified boiler was eventually brought back to England in the 1850s as the "French" or "elephant" boiler.[br]Further ReadingMost details about Edwards are to be found in the biographies of his partner, Arthur Woolf. For example, see T.R.Harris, 1966, Arthur Woolf, 1766–1837, The Cornish Engineer, Truro: D.Bradford Barton; Rhys Jenkins, 1932–3, "A Cornish Engineer, Arthur Woolf, 1766–1837", Transactions of the Newcomen Society 13.

14 Gurney, Sir Goldsworthy
SUBJECT AREA: Automotive engineering, Land transport, Mining and extraction technology, Steam and internal combustion engines[br]b. 14 February 1793 Treator, near Padstow, Cornwall, Englandd. 28 February 1875 Reeds, near Bude, Cornwall, England[br]English pioneer of steam road transport.[br]Educated at Truro Grammar School, he then studied under Dr Avery at Wadebridge to become a doctor of medicine. He settled as a surgeon in Wadebridge, spending his leisure time in building an organ and in the study of chemistry and mechanical science. 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.

15 Hunt, Robert
SUBJECT AREA: Photography, film and optics[br]b. 6 September 1807 Devonport, Devon, Englandd. 19 March 1887 England[br]English photographic pioneer and writer.[br]A chemist by training, Hunt took an early interest in photography and during the 1840s devised several original photographic processes and techniques. The properties of iron sulphate as a developing agent, widely used by wet-collodion photographers, were first described by Hunt in 1844. He was a prolific author and it was as a writer that he was most influential. In 1841 he published the first substantial English-language photographic manual, a work that was to run to six editions. Perhaps his most important work was his Researches on Light, first published in 1844, with a second edition containing considerable additional material appearing in 1854. In 1851 Hunt was appointed Professor of Mechanical Science at the Royal School of Mines in London. He was a founder member of the London (later Royal) Photographic Society in 1853.[br]Principal Honours and DistinctionsMember of the Royal Society 1854.Further ReadingC.Thomas, 1988, Views and Likenesses, Truro: Royal Institution of Cornwall (a brief account of Hunt's life and work).H.Gernsheim and A.Gernsheim, 1969, The History of Photography, rev. edn, London.JW
