7 Graham, George
SUBJECT AREA: Horology[br]b. c.1674 Cumberland, Englandd. 16 November 1751 London, England[br]English watch-and clockmaker who invented the cylinder escapement for watches, the first successful dead-beat escapement for clocks and the mercury compensation pendulum.[br]Graham's father died soon after his birth, so he was raised by his brother. In 1688 he was apprenticed to the London clockmaker Henry Aske, and in 1695 he gained his freedom. He was employed as a journeyman by Tompion in 1696 and later married his niece. In 1711 he formed a partnership with Tompion and effectively ran the business in Tompion's declining years; he took over the business after Tompion died in 1713. In addition to his horological interests he also made scientific instruments, specializing in those for astronomical use. As a person, he was well respected and appears to have lived up to the epithet "Honest George Graham". He befriended John Harrison when he first went to London and lent him money to further his researches at a time when they might have conflicted with his own interests.The two common forms of escapement in use in Graham's time, the anchor escapement for clocks and the verge escapement for watches, shared the same weakness: they interfered severely with the free oscillation of the pendulum and the balance, and thus adversely affected the timekeeping. Tompion's two frictional rest escapements, the dead-beat for clocks and the horizontal for watches, had provided a partial solution by eliminating recoil (the momentary reversal of the motion of the timepiece), but they had not been successful in practice. Around 1720 Graham produced his own much improved version of the dead-beat escapement which became a standard feature of regulator clocks, at least in Britain, until its supremacy was challenged at the end of the nineteenth century by the superior accuracy of the Riefler clock. Another feature of the regulator clock owed to Graham was the mercury compensation pendulum, which he invented in 1722 and published four years later. The bob of this pendulum contained mercury, the surface of which rose or fell with changes in temperature, compensating for the concomitant variation in the length of the pendulum rod. Graham devised his mercury pendulum after he had failed to achieve compensation by means of the difference in expansion between various metals. He then turned his attention to improving Tompion's horizontal escapement, and by 1725 the cylinder escapement existed in what was virtually its final form. From the following year he fitted this escapement to all his watches, and it was also used extensively by London makers for their precision watches. It proved to be somewhat lacking in durability, but this problem was overcome later in the century by using a ruby cylinder, notably by Abraham Louis Breguet. It was revived, in a cheaper form, by the Swiss and the French in the nineteenth century and was produced in vast quantities.[br]Principal Honours and DistinctionsFRS 1720.

8 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

9 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
