12 Sellers, William
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. 19 September 1824 Upper Darby, Pennsylvania, USAd. 24 January 1905 Philadelphia, Pennsylvania, USA[br]American mechanical engineer and inventor.[br]William Sellers was educated at a private school that had been established by his father and other relatives for their children, and at the age of 14 he was apprenticed for seven years to the machinist's trade with his uncle. At the end of his apprenticeship in 1845 he took charge of the machine shop of Fairbanks, Bancroft \& Co. in Providence, Rhode Island. In 1848 he established his own factory manufacturing machine tools and mill gearing in Philadelphia, where he was soon joined by Edward Bancroft, the firm becoming Bancroft \& Sellers. After Bancroft's death the name was changed in 1856 to William Sellers \& Co. and Sellers served as President until the end of his life. His machine tools were characterized by their robust construction and absence of decorative embellishments. In 1868 he formed the Edgemoor Iron Company, of which he was President. This company supplied the structural ironwork for the Centennial Exhibition buildings and much of the material for the Brooklyn Bridge. In 1873 he reorganized the William Butcher Steel Works, renaming it the Midvale Steel Company, and under his presidency it became a leader in the production of heavy ordnance. It was at the Midvale Steel Company that Frederick W. Taylor began, with the encouragement of Sellers, his experiments on cutting tools.In 1860 Sellers obtained the American rights of the patent for the Giffard injector for feeding steam boilers. He later invented his own improvements to the injector, which numbered among his many other patents, most of which related to machine tools. Probably Sellers's most important contribution to the engineering industry was his proposal for a system of screw threads made in 1864 and later adopted as the American national standard.Sellers was a founder member in 1880 of the American Society of Mechanical Engineers and was also a member of many other learned societies in America and other countries, including, in Britain, the Institution of Mechanical Engineers and the Iron and Steel Institute.[br]Principal Honours and DistinctionsChevalier de la Légion d'honneur 1889.

16 Whitworth, Sir Joseph
[br]b. 21 December 1803 Stockport, Cheshire, Englandd. 22 January 1887 Monte Carlo, Monaco[br]English mechanical engineer and pioneer of precision measurement.[br]Joseph Whitworth received his early education in a school kept by his father, but from the age of 12 he attended a school near Leeds. At 14 he joined his uncle's mill near Ambergate, Derbyshire, to learn the business of cotton spinning. In the four years he spent there he realized that he was more interested in the machinery than in managing a cotton mill. In 1821 he obtained employment as a mechanic with Crighton \& Co., Manchester. In 1825 he moved to London and worked for Henry Maudslay and later for the Holtzapffels and Joseph Clement. After these years spent gaining experience, he returned to Manchester in 1833 and set up in a small workshop under a sign "Joseph Whitworth, Tool Maker, from London".The business expanded steadily and the firm made machine tools of all types and other engineering products including steam engines. From 1834 Whitworth obtained many patents in the fields of machine tools, textile and knitting machinery and road-sweeping machines. By 1851 the company was generally regarded as the leading manufacturer of machine tools in the country. Whitworth was a pioneer of precise measurement and demonstrated the fundamental mode of producing a true plane by making surface plates in sets of three. He advocated the use of the decimal system and made use of limit gauges, and he established a standard screw thread which was adopted as the national standard. In 1853 Whitworth visited America as a member of a Royal Commission and reported on American industry. At the time of the Crimean War in 1854 he was asked to provide machinery for manufacturing rifles and this led him to design an improved rifle of his own. Although tests in 1857 showed this to be much superior to all others, it was not adopted by the War Office. Whitworth's experiments with small arms led on to the construction of big guns and projectiles. To improve the quality of the steel used for these guns, he subjected the molten metal to pressure during its solidification, this fluid-compressed steel being then known as "Whitworth steel".In 1868 Whitworth established thirty annual scholarships for engineering students. After his death his executors permanently endowed the Whitworth Scholarships and distributed his estate of nearly half a million pounds to various educational and charitable institutions. Whitworth was elected an Associate of the Institution of Civil Engineers in 1841 and a Member in 1848 and served on its Council for many years. He was elected a Member of the Institution of Mechanical Engineers in 1847, the year of its foundation.[br]Principal Honours and DistinctionsBaronet 1869. FRS 1857.
