101 CPD
abbr. HRcontinuing professional development: ongoing training and education throughout a career to improve the skills and knowledge used to perform a job or succession of jobs. CPD should be a planned, structured process, involving the assessment of development needs and the tailoring of training to meet those needs. CPD is founded on the belief that the development of professionals should not finish after initial qualification, especially in a fast changing business environment in which skills are likely to obsolesce quickly. CPD requires commitment and resources from the employee, the employer, and supportive agencies such as professional bodies. Advocates of CPD argue that it can enhance employability and career development by keeping skills up to date and broadening a person’s skill base. Dominic Cadbury has said that CPD should be centered on the individual, who must take responsibility for the continuing assessment and satisfaction of his or her own development needs. Much can be found in support of the principle of CPD in the concepts of David Kolb’s experiential learning cycle, Peter Honey and Alan Mumford’s learning types, the personal development cycle, and lifelong learning. -
102 Chapman, Frederik Henrik af
SUBJECT AREA: Ports and shipping[br]b. 9 September 1721 Gothenburg, Swedend. 19 August 1808 Karlskrona, Sweden[br]Swedish naval architect and shipbuilder; one of the foremost ship designers of all time.[br]Chapman was born on the west coast of Sweden and was the son of a British naval officer serving in the Swedish Navy. In 1738 he followed in his father's footsteps by joining the naval dockyards as a shipbuilding apprentice. Subsequent experience was gained in other shipyards and by two years (1741–3) in London. His assiduous note taking and study of British shipbuilding were noticed and he was offered appointments in England, but these were refused and he returned to Sweden in 1744 and for a while operated as a ship repairer in partnership with a man called Bagge. In 1749 he started out on his own. He began with a period of study in Stockholm and in London, where he worked for a while under Thomas Simpson, and then went on to France and the Netherlands. During his time in England he learned the art of copper etching, a skill that later stood him in good stead. After some years he was appointed Deputy Master Shipwright to the Swedish Navy, and in 1760 he became Master Shipwright at Sveaborg (now Suomenlinna), the fortress island of Helsinki. There Chapman excelled by designing the coastal defence or skerry fleet that to this day is accepted as beautiful and fit for purpose. He understood the limitations of ship design and throughout his life strove to improve shipbuilding by using the advances in mathematics and science that were then being made. His contribution to the rationalization of thought in ship theory cannot be overemphasized.In 1764 he became Chief Shipbuilder to the Swedish Navy, with particular responsibility for Karlskrona and for Stockholm. He assisted in the new rules for the classification of warships and later introduced standardization to the naval dockyards. He continued to rise in rank and reputation until his retirement in 1793, but to the end his judgement was sought on many matters concerning not only ship design but also the administration of the then powerful Swedish Navy.His most important bequest to his profession is the great book Architectura Navalis Mercatoria, first published in 1768. Later editions were larger and contained additional material. This volume remains one of the most significant works on shipbuilding.[br]Principal Honours and DistinctionsKnighted 1772.

103 Mergenthaler, Ottmar
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 -
104 Smeaton, John
SUBJECT AREA: Civil engineering, Mechanical, pneumatic and hydraulic engineering, Steam and internal combustion engines[br]b. 8 June 1724 Austhorpe, near Leeds, Yorkshire, Englandd. 28 October 1792 Austhorpe, near Leeds, Yorkshire, England[br]English mechanical and civil engineer.[br]As a boy, Smeaton showed mechanical ability, making for himself a number of tools and models. This practical skill was backed by a sound education, probably at Leeds Grammar School. At the age of 16 he entered his father's office; he seemed set to follow his father's profession in the law. In 1742 he went to London to continue his legal studies, but he preferred instead, with his father's reluctant permission, to set up as a scientific instrument maker and dealer and opened a shop of his own in 1748. About this time he began attending meetings of the Royal Society and presented several papers on instruments and mechanical subjects, being elected a Fellow in 1753. His interests were turning towards engineering but were informed by scientific principles grounded in careful and accurate observation.In 1755 the second Eddystone lighthouse, on a reef some 14 miles (23 km) off the English coast at Plymouth, was destroyed by fire. The President of the Royal Society was consulted as to a suitable engineer to undertake the task of constructing a new one, and he unhesitatingly suggested Smeaton. Work began in 1756 and was completed in three years to produce the first great wave-swept stone lighthouse. It was constructed of Portland stone blocks, shaped and pegged both together and to the base rock, and bonded by hydraulic cement, scientifically developed by Smeaton. It withstood the storms of the English Channel for over a century, but by 1876 erosion of the rock had weakened the structure and a replacement had to be built. The upper portion of Smeaton's lighthouse was re-erected on a suitable base on Plymouth Hoe, leaving the original base portion on the reef as a memorial to the engineer.The Eddystone lighthouse made Smeaton's reputation and from then on he was constantly in demand as a consultant in all kinds of engineering projects. He carried out a number himself, notably the 38 mile (61 km) long Forth and Clyde canal with thirty-nine locks, begun in 1768 but for financial reasons not completed until 1790. In 1774 he took charge of the Ramsgate Harbour works.On the mechanical side, Smeaton undertook a systematic study of water-and windmills, to determine the design and construction to achieve the greatest power output. This work issued forth as the paper "An experimental enquiry concerning the natural powers of water and wind to turn mills" and exerted a considerable influence on mill design during the early part of the Industrial Revolution. Between 1753 and 1790 Smeaton constructed no fewer than forty-four mills.Meanwhile, in 1756 he had returned to Austhorpe, which continued to be his home base for the rest of his life. In 1767, as a result of the disappointing performance of an engine he had been involved with at New River Head, Islington, London, Smeaton began his important study of the steam-engine. Smeaton was the first to apply scientific principles to the steam-engine and achieved the most notable improvements in its efficiency since its invention by Newcomen, until its radical overhaul by James Watt. To compare the performance of engines quantitatively, he introduced the concept of "duty", i.e. the weight of water that could be raised 1 ft (30 cm) while burning one bushel (84 lb or 38 kg) of coal. The first engine to embody his improvements was erected at Long Benton colliery in Northumberland in 1772, with a duty of 9.45 million pounds, compared to the best figure obtained previously of 7.44 million pounds. One source of heat loss he attributed to inaccurate boring of the cylinder, which he was able to improve through his close association with Carron Ironworks near Falkirk, Scotland.[br]Principal Honours and DistinctionsFRS 1753.Bibliography1759, "An experimental enquiry concerning the natural powers of water and wind to turn mills", Philosophical Transactions of the Royal Society.Towards the end of his life, Smeaton intended to write accounts of his many works but only completed A Narrative of the Eddystone Lighthouse, 1791, London.Further ReadingS.Smiles, 1874, Lives of the Engineers: Smeaton and Rennie, London.

105 Stephenson, George
[br]b. 9 June 1781 Wylam, Northumberland, Englandd. 12 August 1848 Tapton House, Chesterfield, England[br]English engineer, "the father of railways".[br]George Stephenson was the son of the fireman of the pumping engine at Wylam colliery, and horses drew wagons of coal along the wooden rails of the Wylam wagonway past the house in which he was born and spent his earliest childhood. While still a child he worked as a cowherd, but soon moved to working at coal pits. At 17 years of age he showed sufficient mechanical talent to be placed in charge of a new pumping engine, and had already achieved a job more responsible than that of his father. Despite his position he was still illiterate, although he subsequently learned to read and write. He was largely self-educated.In 1801 he was appointed Brakesman of the winding engine at Black Callerton pit, with responsibility for lowering the miners safely to their work. Then, about two years later, he became Brakesman of a new winding engine erected by Robert Hawthorn at Willington Quay on the Tyne. Returning collier brigs discharged ballast into wagons and the engine drew the wagons up an inclined plane to the top of "Ballast Hill" for their contents to be tipped; this was one of the earliest applications of steam power to transport, other than experimentally.In 1804 Stephenson moved to West Moor pit, Killingworth, again as Brakesman. In 1811 he demonstrated his mechanical skill by successfully modifying a new and unsatisfactory atmospheric engine, a task that had defeated the efforts of others, to enable it to pump a drowned pit clear of water. The following year he was appointed Enginewright at Killingworth, in charge of the machinery in all the collieries of the "Grand Allies", the prominent coal-owning families of Wortley, Liddell and Bowes, with authorization also to work for others. He built many stationary engines and he closely examined locomotives of John Blenkinsop's type on the Kenton \& Coxlodge wagonway, as well as those of William Hedley at Wylam.It was in 1813 that Sir Thomas Liddell requested George Stephenson to build a steam locomotive for the Killingworth wagonway: Blucher made its first trial run on 25 July 1814 and was based on Blenkinsop's locomotives, although it lacked their rack-and-pinion drive. George Stephenson is credited with building the first locomotive both to run on edge rails and be driven by adhesion, an arrangement that has been the conventional one ever since. Yet Blucher was far from perfect and over the next few years, while other engineers ignored the steam locomotive, Stephenson built a succession of them, each an improvement on the last.During this period many lives were lost in coalmines from explosions of gas ignited by miners' lamps. By observation and experiment (sometimes at great personal risk) Stephenson invented a satisfactory safety lamp, working independently of the noted scientist Sir Humphry Davy who also invented such a lamp around the same time.In 1817 George Stephenson designed his first locomotive for an outside customer, the Kilmarnock \& Troon Railway, and in 1819 he laid out the Hetton Colliery Railway in County Durham, for which his brother Robert was Resident Engineer. This was the first railway to be worked entirely without animal traction: it used inclined planes with stationary engines, self-acting inclined planes powered by gravity, and locomotives.On 19 April 1821 Stephenson was introduced to Edward Pease, one of the main promoters of the Stockton \& Darlington Railway (S \& DR), which by coincidence received its Act of Parliament the same day. George Stephenson carried out a further survey, to improve the proposed line, and in this he was assisted by his 18-year-old son, Robert Stephenson, whom he had ensured received the theoretical education which he himself lacked. It is doubtful whether either could have succeeded without the other; together they were to make the steam railway practicable.At George Stephenson's instance, much of the S \& DR was laid with wrought-iron rails recently developed by John Birkinshaw at Bedlington Ironworks, Morpeth. These were longer than cast-iron rails and were not brittle: they made a track well suited for locomotives. In June 1823 George and Robert Stephenson, with other partners, founded a firm in Newcastle upon Tyne to build locomotives and rolling stock and to do general engineering work: after its Managing Partner, the firm was called Robert Stephenson \& Co.In 1824 the promoters of the Liverpool \& Manchester Railway (L \& MR) invited George Stephenson to resurvey their proposed line in order to reduce opposition to it. William James, a wealthy land agent who had become a visionary protagonist of a national railway network and had seen Stephenson's locomotives at Killingworth, had promoted the L \& MR with some merchants of Liverpool and had carried out the first survey; however, he overreached himself in business and, shortly after the invitation to Stephenson, became bankrupt. In his own survey, however, George Stephenson lacked the assistance of his son Robert, who had left for South America, and he delegated much of the detailed work to incompetent assistants. During a devastating Parliamentary examination in the spring of 1825, much of his survey was shown to be seriously inaccurate and the L \& MR's application for an Act of Parliament was refused. The railway's promoters discharged Stephenson and had their line surveyed yet again, by C.B. Vignoles.The Stockton \& Darlington Railway was, however, triumphantly opened in the presence of vast crowds in September 1825, with Stephenson himself driving the locomotive Locomotion, which had been built at Robert Stephenson \& Co.'s Newcastle works. Once the railway was at work, horse-drawn and gravity-powered traffic shared the line with locomotives: in 1828 Stephenson invented the horse dandy, a wagon at the back of a train in which a horse could travel over the gravity-operated stretches, instead of trotting behind.Meanwhile, in May 1826, the Liverpool \& Manchester Railway had successfully obtained its Act of Parliament. Stephenson was appointed Engineer in June, and since he and Vignoles proved incompatible the latter left early in 1827. The railway was built by Stephenson and his staff, using direct labour. A considerable controversy arose c. 1828 over the motive power to be used: the traffic anticipated was too great for horses, but the performance of the reciprocal system of cable haulage developed by Benjamin Thompson appeared in many respects superior to that of contemporary locomotives. The company instituted a prize competition for a better locomotive and the Rainhill Trials were held in October 1829.Robert Stephenson had been working on improved locomotive designs since his return from America in 1827, but it was the L \& MR's Treasurer, Henry Booth, who suggested the multi-tubular boiler to George Stephenson. This was incorporated into a locomotive built by Robert Stephenson for the trials: Rocket was entered by the three men in partnership. The other principal entrants were Novelty, entered by John Braithwaite and John Ericsson, and Sans Pareil, entered by Timothy Hackworth, but only Rocket, driven by George Stephenson, met all the organizers' demands; indeed, it far surpassed them and demonstrated the practicability of the long-distance steam railway. With the opening of the Liverpool \& Manchester Railway in 1830, the age of railways began.Stephenson was active in many aspects. He advised on the construction of the Belgian State Railway, of which the Brussels-Malines section, opened in 1835, was the first all-steam railway on the European continent. In England, proposals to link the L \& MR with the Midlands had culminated in an Act of Parliament for the Grand Junction Railway in 1833: this was to run from Warrington, which was already linked to the L \& MR, to Birmingham. George Stephenson had been in charge of the surveys, and for the railway's construction he and J.U. Rastrick were initially Principal Engineers, with Stephenson's former pupil Joseph Locke under them; by 1835 both Stephenson and Rastrick had withdrawn and Locke was Engineer-in-Chief. Stephenson remained much in demand elsewhere: he was particularly associated with the construction of the North Midland Railway (Derby to Leeds) and related lines. He was active in many other places and carried out, for instance, preliminary surveys for the Chester \& Holyhead and Newcastle \& Berwick Railways, which were important links in the lines of communication between London and, respectively, Dublin and Edinburgh.He eventually retired to Tapton House, Chesterfield, overlooking the North Midland. A man who was self-made (with great success) against colossal odds, he was ever reluctant, regrettably, to give others their due credit, although in retirement, immensely wealthy and full of honour, he was still able to mingle with people of all ranks.[br]Principal Honours and DistinctionsPresident, Institution of Mechanical Engineers, on its formation in 1847.
