1 Bentham, Sir Samuel
SUBJECT AREA: Ports and shipping[br]b. 11 January 1757 Englandd. 31 May 1831 London, England[br]English naval architect and engineer.[br]He was the son of Jeremiah Bentham, a lawyer. His mother died when he was an infant and his early education was at Westminster. At the age of 14 he was apprenticed to a master shipwright at Woolwich and later at Chatham Dockyard, where he made some small improvements in the fittings of ships. In 1778 he completed his apprenticeship and sailed on the Bienfaisant on a summer cruise of the Channel Fleet where he suggested and supervised several improvements to the steering gear and gun fittings.Unable to find suitable employment at home, he sailed for Russia to study naval architecture and shipbuilding, arriving at St Petersburg in 1780, whence he travelled throughout Russia as far as the frontier of China, examining mines and methods of working metals. He settled in Kritchev in 1782 and there established a small shipyard with a motley work-force. In 1784 he was appointed to command a battalion. He set up a yard on the "Panopticon" principle, with all workshops radiating from his own central office. He increased the armament of his ships greatly by strengthening the hulls and fitting guns without recoil, which resulted in a great victory over the Turks at Liman in 1788. For this he was awarded the Cross of St George and promoted to Brigadier- General. Soon after, he was appointed to a command in Siberia, where he was responsible for opening up the resources of the country greatly by developing river navigation.In 1791 he returned to England, where he was at first involved in the development of the Panopticon for his brother as well as with several other patents. In 1795 he was asked to look into the mechanization of the naval dockyards, and for the next eighteen years he was involved in improving methods of naval construction and machinery. He was responsible for the invention of the steam dredger, the caisson method of enclosing the entrances to docks, and the development of non-recoil cannonades of large calibre.His intervention in the maladministration of the naval dockyards resulted in an enquiry that brought about the clearing-away of much corruption, making him very unpopular. As a result he was sent to St Petersburg to arrange for the building of a number of ships for the British navy, in which the Russians had no intention of co-operating. On his return to England after two years he was told that his office of Inspector-General of Navy Works had been abolished and he was appointed to the Navy Board; he had several disagreements with John Rennie and in 1812 was told that this office, too, had been abolished. He went to live in France, where he stayed for thirteen years, returning in 1827 to arrange for the publication of some of his papers.There is some doubt about his use of his title: there is no record of his having received a knighthood in England, but it was assumed that he was authorized to use the title, granted to him in Russia, after his presentation to the Tsar in 1809.[br]Further ReadingMary Sophia Bentham, Life of Brigadier-General Sir Samuel Bentham, K.S.G., Formerly Inspector of Naval Works (written by his wife, who died before completing it; completed by their daughter).IMcN -

3 Maudslay, Henry
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. 22 August 1771 Woolwich, Kent, Englandd. 15 February 1831 Lambeth, London, England[br]English precision toolmaker and engineer.[br]Henry Maudslay was the third son of an ex-soldier and storekeeper at Woolwich Arsenal. At the age of 12 he was employed at the Arsenal filling cartridges; two years later he was transferred to the woodworking department, adjacent to the smithy, to which he moved when 15 years old. He was a rapid learner, and three years later Joseph Bramah took him on for the construction of special tools required for the mass-production of his locks. Maudslay was thus employed for the next eight years. He became Bramah's foreman, married his housekeeper, Sarah Tindale, and, unable to better himself, decided to leave and set up on his own. He soon outgrew his first premises in Wells Street and moved to Margaret Street, off Oxford Street, where some examples of his workmanship were displayed in the window. These caught the attention of a visiting Frenchman, de Bacquancourt; he was a friend of Marc Isambard Brunel, who was then in the early stages of designing the block-making machinery later installed at Portsmouth dockyard.Brunel wanted first a set of working models, as he did not think that the Lords of the Admiralty would be capable of understanding engineering drawings; Maudslay made these for him within the next two years. Sir Samuel Bentham, Inspector-General of Naval Works, agreed that Brunel's system was superior to the one that he had gone some way in developing; the Admiralty approved, and an order was placed for the complete plant. The manufacture of the machinery occupied Maudslay for the next six years; he was assisted by a draughtsman whom he took on from Portsmouth dockyard, Joshua Field (1786–1863), who became his partner in Maudslay, Son and Field. There were as many as eighty employees at Margaret Street until, in 1810, larger premises became necessary and a new works was built at Lambeth Marsh where, eventually, there were up to two hundred workers. The new factory was flanked by two houses, one of which was occupied by Maudslay, the other by Field. The firm became noted for its production of marine steam-engines, notably Maudslay's table engine which was first introduced in 1807.Maudslay was a consummate craftsman who was never happier than when working at his bench or at a machine tool; he was also one of the first engineers to appreciate the virtues of standardization. Evidence of this appreciation is to be found in his work in the development of the Bramah lock and then on the machine tools for the manufacture of ship's blocks to Marc Brunel's designs; possibly his most important contribution was the invention in 1797 of the metal lathe. He made a number of surface plates of the finest quality. The most celebrated of his numerous measuring devices was a micrometer-based machine which he termed his "Lord Chancellor" because, in the machine shop, it represented the "final court of appeal", measuring to one-thousandth of an inch.[br]Further Reading1934–5, "Maudslay, Sons \& Field as general engineers", Transactions of the Newcomen Society 15, London.1963, Engineering Heritage, Vol. 1, London: Institution of Mechanical Engineers.
