1 Nasmyth, James Hall
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. 19 August 1808 Edinburgh, Scotlandd. 7 May 1890 London, England[br]Scottish mechanical engineer and inventor of the steam-hammer.[br]James Nasmyth was the youngest son of Alexander Nasmyth (1758–1840), the portrait and landscape painter. According to his autobiography he was named James Hall after his father's friend, the geologist Sir James Hall (1761–1832), but he seems never to have used his second name in official documents. He received an elementary education at Edinburgh High School, but left at the age of 12. He attended evening classes at the Edinburgh School of Arts for the instruction of Mechanics between 1821 and 1825, and gained experience as a mechanic at an early age in his father's workshop. He shared these early experiences with his brother George, who was only a year or so older, and in the 1820s the brothers built several model steam engines and a steam-carriage capable of carrying eight passengers on the public roads. In 1829 Nasmyth obtained a position in London as personal assistant to Henry Maudslay, and after Maudslay's death in February 1831 he remained with Maudslay's partner, Joshua Field, for a short time. He then returned to Edinburgh, where he and his brother George started in a small way as general engineers. In 1834 they moved to a small workshop in Manchester, and in 1836, with the aid of financial backing from some Manchester businessmen, they established on a site at Patricroft, a few miles from the city, the works which became known as the Bridgewater Foundry. They were soon joined by a third partner, Holbrook Gaskell (1813–1909), who looked after the administration of the business, the firm then being known as Nasmyths Gaskell \& Co. They specialized in making machine tools, and Nasmyth invented many improvements so that they soon became one of the leading manufacturers in this field. They also made steam locomotives for the rapidly developing railways. James Nasmyth's best-known invention was the steam-hammer, which dates from 1839 but was not patented until 1842. The self-acting control gear was probably the work of Robert Wilson and ensured the commercial success of the invention. George Nasmyth resigned from the partnership in 1843 and in 1850 Gaskell also resigned, after which the firm continued as James Nasmyth \& Co. James Nasmyth himself retired at the end of 1856 and went to live at Penshurst, Kent, in a house which he named "Hammerfield" where he devoted his time mainly to his hobby of astronomy. Robert Wilson returned to become Managing Partner of the firm, which later became Nasmyth, Wilson \& Co. and retained that style until its closure in 1940. Nasmyth's claim to be the sole inventor of the steam-hammer has been disputed, but his patent of 1842 was not challenged and the fourteen-year monopoly ensured the prosperity of the business so that he was able to retire at the age of 48. At his death in 1890 he left an estate valued at £243,805.[br]Bibliography1874, with J.Carpenter, The Moon Considered as a Planet, a World, and a Satellite, London.1883, Autobiography, ed.

3 Field, Joshua
SUBJECT AREA: Civil engineering, Mechanical, pneumatic and hydraulic engineering, Steam and internal combustion engines[br]b. 1786 Hackney, London, Englandd. 11 August 1863 Balham Hill, Surrey, England[br]English mechanical engineer, co-founder of the Institution of Civil Engineers.[br]Joshua Field was educated at a boarding school in Essex until the age of 16, when he obtained employment at the Royal Dockyards at Portsmouth under the Chief Mechanical Superintendent, Simon Goodrich (1773–1847), and later in the drawing office at the Admiralty in Whitehall. At this time, machinery for the manufacture of ships' blocks was being made for the Admiralty by Henry Maudslay, who was in need of a competent draughtsman, and Goodrich recommended Joshua Field. This was the beginning of Field's long association with Maudslay; he later became a partner in the firm which was for many years known as Maudslay, Sons \& Field. They undertook a variety of mechanical engineering work but were renowned for marine steam engines, with Field being responsible for much of the design work in the early years. Joshua Field was the eldest of the eight young men who in 1818 founded the Institution of Civil Engineers; he was the first Chairman of the Institution and later became a vice-president. He was the only one of the founders to be elected President and was the first mechanical engineer to hold that office. James Nasmyth in his autobiography relates that Joshua Field kept a methodical account of his technical discussions in a series of note books which were later indexed. Some of these diaries have survived, and extracts from the notes he made on a tour of the industrial areas of the Midlands and the North West in 1821 have been published.[br]Principal Honours and DistinctionsFRS 1836.
