10 Shortt, William Hamilton
SUBJECT AREA: Horology[br]b. 28 September 1881d. 4 February 1971[br]British railway engineer and amateur horologist who designed the first successful free-pendulum clock.[br]Shortt entered the Engineering Department of the London and South Western Railway as an engineering cadet in 1902, remaining with the company and its successors until he retired in 1946. He became interested in precision horology in 1908, when he designed an instrument for recording the speed of trains; this led to a long and fruitful collaboration with Frank HopeJones, the proprietor of the Synchronome Company. This association culminated in the installation of a free-pendulum clock, with an accuracy of the order of one second per year, at Edinburgh Observatory in 1921. The clock's performance was far better than that of existing clocks, such as the Riefler, and a slightly modified version was produced commercially by the Synchronome Company. These clocks provided the time standard at Greenwich and many other observatories and scientific institutions across the world until they were supplanted by the quartz clock.The period of a pendulum is constant if it swings freely with a constant amplitude in a vacuum. However, this ideal state cannot be achieved in a clock because the pendulum must be impulsed to maintain its amplitude and the swings have to be counted to indicate time. The free-pendulum clock is an attempt to approach this ideal as closely as possible. In 1898 R.J. Rudd used a slave clock, synchronized with a free pendulum, to time the impulses delivered to the free pendulum. This clock was not successful, but it provided the inspiration for Shortt's clock, which operates on the same principle. The Shortt clock used a standard Synchronome electric clock as the slave, and its pendulum was kept in step with the free pendulum by means of the "hit and miss" synchronizer that Shortt had patented in 1921. This allowed the pendulum to swing freely (in a vacuum), apart from the fraction of a second in which it received an impulse each half-minute.[br]Principal Honours and DistinctionsMaster of the Clockmakers' Company 1950.

11 Whitehead, Robert
SUBJECT AREA: Weapons and armour[br]b. 3 January 1823 Bolton-le-Moors, Lancashire, Englandd. 19 November 1903 Shrivenham, Wiltshire, England[br]English inventor of the torpedo.[br]At the age of 14 Whitehead was apprenticed by his father, who ran a cotton-bleaching business, to an engineering firm in Manchester. He moved in 1847 to join his uncle, who was the Manager of another engineering firm, and three years later Whitehead set up on his own in Milan, where he made mechanical improvements to the silk-weaving industry and designed drainage machines for the Lombardy marshes.In 1848 he was forced to move from Italy because of the revolution and settled in Fiume, which was then part of Austria. There he concen-. trated on designing and building engines for warships, and in 1864 the Austrians invited him to participate in a project to develop a "floating torpedo". In those days the torpedo was synonymous with the underwater mine, and Whitehead believed that he could do better than this proposal and produce an explosive weapon that could propel itself through the water. He set to work with his son John and a mechanic, producing the first version of his torpedo in 1866. It had a range of only 700 yd (640 m) and a speed of just 7 knots (13 km/h), as well as depth-keeping problems, but even so, especially after he had reduced the last problem by the use of a "balance chamber", the Austrian authorities were sufficiently impressed to buy construction rights and to decorate him. Other navies quickly followed suit and within twenty years almost every navy in the world was equipped with the Whitehead torpedo, its main attraction being that no warship, however large, was safe from it. During this time Whitehead continued to improve on his design, introducing a servo-motor and gyroscope, thereby radically improving range, speed and accuracy.[br]Principal Honours and DistinctionsOrder of Max Joseph (Austria) 1868. Légion d'honneur 1884. Whitehead also received decorations from Prussia, Denmark, Portugal, Italy and Greece.Further ReadingDictionary of National Biography, 1912, Vol. 3, Suppl. 2, London: Smith, Elder.CM -
12 Shrapnel, General Henry
SUBJECT AREA: Weapons and armour[br]b. 3 June 1761 Bradford-on-Avon, Englandd. 13 March 1842 Southampton, England[br]English professional soldier and inventor of shrapnel ammunition.[br]The youngest of nine children, Shrapnel was commissioned into the Royal Artillery in July 1779. His early military service was in Newfoundland and it was on his return to England in 1784 that he began to interest himself in artillery ammunition. His particular concern was to develop a round that would be more effective against infantry than the existing solid cannon-ball and canister round. The result was a hollow, spherical shell filled with lead musket balls and fitted with a bursting charge and fuse. His development of the shell was interrupted by active service in the Low Countries in 1793–4, during which he was wounded, and duty in the West Indies. Nevertheless, in 1803 the British Army adopted his shell, which during the next twelve years played a significant part on the battlefield.In 1804 Shrapnel was appointed Assistant Inspector of Artillery and made further contributions to the science of gunnery, drawing up a series of range tables to improve accuracy of fire, inventing the brass tangent slide for better sighting of guns, and improving the production of howitzers and mortars by way of the invention of parabolic chambers. His services were recognized in 1814 by a Treasury grant of £1,200 per annum for life. He was promoted Major-General in 1819 and appointed a Colonel-Commandant of the Royal Artillery in 1827, and in the 1830s there was talk of him being made a baronet, but nothing came of it. Shrapnel remains a current military term, although modern bursting shells rely on the fragmentation of the casing of the projectile for their effect rather than his original concept of having shot inside them.[br]Principal Honours and DistinctionsColonel-Commandant of the Royal Artillery 1827.Further ReadingDictionary of National Biography, 1897, Vol. 52, London: Smith, Elder.CMBiographical history of technology > Shrapnel, General Henry
