41 Clark, Edwin
SUBJECT AREA: Civil engineering[br]b. 7 January 1814 Marlow, Buckinghamshire, Englandd. 22 October 1894 Marlow, Buckinghamshire, England[br]English civil engineer.[br]After a basic education in mathematics, latin, French and geometry, Clark was articled to a solicitor, but he left after two years because he did not like the work. He had no permanent training otherwise, and for four years he led an idle life, becoming self-taught in the subjects that interested him. He eventually became a teacher at his old school before entering Cambridge, although he returned home after two years without taking a degree. He then toured the European continent extensively, supporting himself as best he could. He returned to England in 1839 and obtained further teaching posts. With the railway boom in progress he decided to become a surveyor and did some work on a proposed line between Oxford and Brighton.After being promised an interview with Robert Stephenson, he managed to see him in March 1846. Stephenson took a liking to Clark and asked him to investigate the strains on the Britannia Bridge tubes under various given conditions. This work so gained Stephenson's full approval that, after being entrusted with experiments and designs, Clark was appointed Resident Engineer for the Britannia Bridge across the Menai Straits. He not only completed the bridge, which was opened on 19 October 1850, but also wrote the history of its construction. After the completion of the bridge—and again without any professional experience—he was appointed Engineer-in-Chief to the Electric and International Telegraph Company. He was consulted by Captain Mark Huish of the London \& North Western Railway on a telegraphic system for the railway, and in 1853 he introduced the Block Telegraph System.Clark was engaged on the Crystal Palace and was responsible for many railway bridges in Britain and abroad. He was Engineer and part constructor of the harbour at Callao, Peru, and also of harbour works at Colón, Panama. On canal works he was contractor for the marine canal, the Morskoy Canal, in 1875 between Kronstadt and St Petersburg. His great work on canals, however, was the concept with Edward Leader Williams of the hydraulically operated barge lift at Anderton, Cheshire, linking the Weaver Navigation to the Trent \& Mersey Canal, whose water levels have a vertical separation of 50 ft (15 m). This was opened on 26 July 1875. The structure so impressed the French engineers who were faced with a bottleneck of five locks on the Neuffossée Canal south of Saint-Omer that they commissioned Clark to design a lift there. This was completed in 1878 and survives as a historic monument. The design was also adopted for four lifts on the Canal du Centre at La Louvière in Belgium, but these were not completed until after Clark's death.JHB -

43 Glacier studies
Gen Mgtresearch experiments conducted at the Glacier Metal Company in London from 1948 to 1965 to investigate the development of group relations, the effects of change, and employee roles and responsibilities. The Glacier studies were conducted by the Tavistock Institute of Human Relations with the research being headed by Elliot Jaques and Fred Emery. Findings from the initial study came from a methodology called “working-through,” which examined possible social and personal factors at play in any potential dispute. From this arose an early form of works council where employees could participate in setting policy for their department. It was also discovered that employees felt the need to have their role and status defined in a way acceptable to both themselves and their colleagues. This research into job roles led Jaques to come up with the notion of the time span of discretion, according to which all jobs, no matter how strictly defined, have some level of content that requires judgment and therefore discretion by the jobholder. Jaques then examined this phenomenon in bureaucratic organizations. In defining a bureaucracy as a hierarchical system in which employees are accountable to their bosses for the work they do, he took a different stance from Max Weber. Much like the Hawthorne experiments, the Glacier studies had far-reaching implications for the way organizations were managed. The initial findings were written up by Jaques in The Changing Culture of a Factory (1951). In 1965, Jaques published the Glacier Project Papers with Wilfred Brown, the managing director of Glacier. -
44 Leonardo da Vinci
[br]b. 15 April 1452 Vinci, near Florence, Italy,d. 2 May 1519 St Cloux, near Amboise, France.[br]Italian scientist, engineer, inventor and artist.[br]Leonardo was the illegitimate son of a Florentine lawyer. His first sixteen years were spent with the lawyer's family in the rural surroundings of Vinci, which aroused in him a lifelong love of nature and an insatiable curiosity in it. He received little formal education but extended his knowledge through private reading. That gave him only a smattering of Latin, a deficiency that was to be a hindrance throughout his active life. At sixteen he was apprenticed in the studio of Andrea del Verrochio in Florence, where he received a training not only in art but in a wide variety of crafts and technical arts.In 1482 Leonardo went to Milan, where he sought and obtained employment with Ludovico Sforza, later Duke of Milan, partly to sculpt a massive equestrian statue of Ludovico but the work never progressed beyond the full-scale model stage. He did, however, complete the painting which became known as the Virgin of the Rocks and in 1497 his greatest artistic achievement, The Last Supper, commissioned jointly by Ludovico and the friars of Santa Maria della Grazie and painted on the wall of the monastery's refectory. Leonardo was responsible for the court pageants and also devised a system of irrigation to supply water to the plains of Lombardy. In 1499 the French army entered Milan and deposed Leonardo's employer. Leonardo departed and, after a brief visit to Mantua, returned to Florence, where for a time he was employed as architect and engineer to Cesare Borgia, Duke of Romagna. Around 1504 he completed another celebrated work, the Mona Lisa.In 1506 Leonardo began his second sojourn in Milan, this time in the service of King Louis XII of France, who appointed him "painter and engineer". In 1513 Leonardo left for Rome in the company of his pupil Francesco Melzi, but his time there was unproductive and he found himself out of touch with the younger artists active there, Michelangelo above all. In 1516 he accepted with relief an invitation from King François I of France to reside at the small château of St Cloux in the royal domain of Amboise. With the pension granted by François, Leonardo lived out his remaining years in tranquility at St Cloux.Leonardo's career can hardly be regarded as a success or worthy of such a towering genius. For centuries he was known only for the handful of artistic works that he managed to complete and have survived more or less intact. His main activity remained hidden until the nineteenth and twentieth centuries, during which the contents of his notebooks were gradually revealed. It became evident that Leonardo was one of the greatest scientific investigators and inventors in the history of civilization. Throughout his working life he extended a searching curiosity over an extraordinarily wide range of subjects. The notes show careful investigation of questions of mechanical and civil engineering, such as power transmission by means of pulleys and also a form of chain belting. The notebooks record many devices, such as machines for grinding and polishing lenses, a lathe operated by treadle-crank, a rolling mill with conical rollers and a spinning machine with pinion and yard divider. Leonardo made an exhaustive study of the flight of birds, with a view to designing a flying machine, which obsessed him for many years.Leonardo recorded his observations and conclusions, together with many ingenious inventions, on thousands of pages of manuscript notes, sketches and drawings. There are occasional indications that he had in mind the publication of portions of the notes in a coherent form, but he never diverted his energy into putting them in order; instead, he went on making notes. As a result, Leonardo's impact on the development of science and technology was virtually nil. Even if his notebooks had been copied and circulated, there were daunting impediments to their understanding. Leonardo was left-handed and wrote in mirror-writing: that is, in reverse from right to left. He also used his own abbreviations and no punctuation.At his death Leonardo bequeathed his entire output of notes to his friend and companion Francesco Melzi, who kept them safe until his own death in 1570. Melzi left the collection in turn to his son Orazio, whose lack of interest in the arts and sciences resulted in a sad period of dispersal which endangered their survival, but in 1636 the bulk of them, in thirteen volumes, were assembled and donated to the Ambrosian Library in Milan. These include a large volume of notes and drawings compiled from the various portions of the notebooks and is now known as the Codex Atlanticus. There they stayed, forgotten and ignored, until 1796, when Napoleon's marauding army overran Italy and art and literary works, including the thirteen volumes of Leonardo's notebooks, were pillaged and taken to Paris. After the war in 1815, the French government agreed to return them but only the Codex Atlanticus found its way back to Milan; the rest remained in Paris. The appendix to one notebook, dealing with the flight of birds, was later regarded as of sufficient importance to stand on its own. Four small collections reached Britain at various times during the seventeenth and eighteenth centuries; of these, the volume in the Royal Collection at Windsor Castle is notable for its magnificent series of anatomical drawings. Other collections include the Codex Leicester and Codex Arundel in the British Museum in London, and the Madrid Codices in Spain.Towards the end of the nineteenth century, Leonardo's true stature as scientist, engineer and inventor began to emerge, particularly with the publication of transcriptions and translations of his notebooks. The volumes in Paris appeared in 1881–97 and the Codex Atlanticus was published in Milan between 1894 and 1904.[br]Principal Honours and Distinctions"Premier peintre, architecte et mécanicien du Roi" to King François I of France, 1516.Further ReadingE.MacCurdy, 1939, The Notebooks of Leonardo da Vinci, 2 vols, London; 2nd edn, 1956, London (the most extensive selection of the notes, with an English translation).G.Vasari (trans.
