2 Boole, George
SUBJECT AREA: Electronics and information technology[br]b. 2 November 1815 Lincoln, Englandd. 8 December 1864 Ballintemple, Coounty Cork, Ireland[br]English mathematician whose development of symbolic logic laid the foundations for the operating principles of modern computers.[br]Boole was the son of a tradesman, from whom he learned the principles of mathematics and optical-component manufacturing. From the early age of 16 he taught in a number of schools in West Yorkshire, and when only 20 he opened his own school in Lincoln. There, at the Mechanical Institute, he avidly read mathematical journals and the works of great mathematicians such as Lagrange, Laplace and Newton and began to tackle a variety of algebraic problems. This led to the publication of a constant stream of original papers in the newly launched Cambridge Mathematical Journal on topics in the fields of algebra and calculus, for which in 1844 he received the Royal Society Medal.In 1847 he wrote The Mathematical Analysis of Logic, which applied algebraic symbolism to logical forms, whereby the presence or absence of properties could be represented by binary states and combined, just like normal algebraic equations, to derive logical statements about a series of operations. This laid the foundations for the binary logic used in modern computers, which, being based on binary on-off devices, greatly depend on the use of such operations as "and", "nand" ("not and"), "or" and "nor" ("not or"), etc. Although he lacked any formal degree, this revolutionary work led to his appointment in 1849 to the Chair of Mathematics at Queen's College, Cork, where he continued his work on logic and also produce treatises on differential equations and the calculus of finite differences.[br]Principal Honours and DistinctionsRoyal Society Medal 1844.

4 Maxim, Sir Hiram Stevens
[br]b. 5 February 1840 Brockway's Mills, Maine, USAd. 24 November 1916 Streatham, London, England[br]American (naturalized British) inventor; designer of the first fully automatic machine gun and of an experimental steam-powered aircraft.[br]Maxim was born the son of a pioneer farmer who later became a wood turner. Young Maxim was first apprenticed to a carriage maker and then embarked on a succession of jobs before joining his uncle in his engineering firm in Massachusetts in 1864. As a young man he gained a reputation as a boxer, but it was his uncle who first identified and encouraged Hiram's latent talent for invention.It was not, however, until 1878, when Maxim joined the first electric-light company to be established in the USA, as its Chief Engineer, that he began to make a name for himself. He developed an improved light filament and his electric pressure regulator not only won a prize at the first International Electrical Exhibition, held in Paris in 1881, but also resulted in his being made a Chevalier de la Légion d'honneur. While in Europe he was advised that weapons development was a more lucrative field than electricity; consequently, he moved to England and established a small laboratory at Hatton Garden, London. He began by investigating improvements to the Gatling gun in order to produce a weapon with a faster rate of fire and which was more accurate. In 1883, by adapting a Winchester carbine, he successfully produced a semi-automatic weapon, which used the recoil to cock the gun automatically after firing. The following year he took this concept a stage further and produced a fully automatic belt-fed weapon. The recoil drove barrel and breechblock to the vent. The barrel then halted, while the breechblock, now unlocked from the former, continued rearwards, extracting the spent case and recocking the firing mechanism. The return spring, which it had been compressing, then drove the breechblock forward again, chambering the next round, which had been fed from the belt, as it did so. Keeping the trigger pressed enabled the gun to continue firing until the belt was expended. The Maxim gun, as it became known, was adopted by almost every army within the decade, and was to remain in service for nearly fifty years. Maxim himself joined forces with the large British armaments firm of Vickers, and the Vickers machine gun, which served the British Army during two world wars, was merely a refined version of the Maxim gun.Maxim's interests continued to occupy several fields of technology, including flight. In 1891 he took out a patent for a steam-powered aeroplane fitted with a pendulous gyroscopic stabilizer which would maintain the pitch of the aeroplane at any desired inclination (basically, a simple autopilot). Maxim decided to test the relationship between power, thrust and lift before moving on to stability and control. He designed a lightweight steam-engine which developed 180 hp (135 kW) and drove a propeller measuring 17 ft 10 in. (5.44 m) in diameter. He fitted two of these engines into his huge flying machine testrig, which needed a wing span of 104 ft (31.7 m) to generate enough lift to overcome a total weight of 4 tons. The machine was not designed for free flight, but ran on one set of rails with a second set to prevent it rising more than about 2 ft (61 cm). At Baldwyn's Park in Kent on 31 July 1894 the huge machine, carrying Maxim and his crew, reached a speed of 42 mph (67.6 km/h) and lifted off its rails. Unfortunately, one of the restraining axles broke and the machine was extensively damaged. Although it was subsequently repaired and further trials carried out, these experiments were very expensive. Maxim eventually abandoned the flying machine and did not develop his idea for a stabilizer, turning instead to other projects. At the age of almost 70 he returned to the problems of flight and designed a biplane with a petrol engine: it was built in 1910 but never left the ground.In all, Maxim registered 122 US and 149 British patents on objects ranging from mousetraps to automatic spindles. Included among them was a 1901 patent for a foot-operated suction cleaner. In 1900 he became a British subject and he was knighted the following year. He remained a larger-than-life figure, both physically and in character, until the end of his life.[br]Principal Honours and DistinctionsChevalier de la Légion d'Honneur 1881.

5 Hunter, John
SUBJECT AREA: Medical technology[br]b. 14 (registered 13) February 1728 East Kilbride, Lanarkshire, Scotlandd. 16 October 1793 London, England[br]Scottish surgeon and anatomist, pioneer of experimental methods in medicine and surgery.[br]The younger brother of William Hunter (1718–83), who was of great distinction but perhaps of slightly less achievement in similar fields, he owed much of his early experience to his brother; William, after a period at Glasgow University, moved to St George's Hospital, London. In his later teens, John assisted a brother-in-law with cabinet-making. This appears to have contributed to the lifelong mechanical skill which he displayed as a dissector and surgeon. This skill was particularly obvious when, after following William to London in 1748, he held post at a number of London teaching hospitals before moving to St George's in 1756. A short sojourn at Oxford in 1755 appears to have been unfruitful.Despite his deepening involvement in the study of comparative anatomy, facilitated by the purchase of animals from the Tower menagerie and travelling show people, he accepted an appointment as a staff surgeon in the Army in 1760, participating in the expedition to Belle Isle and also serving in Portugal. He returned home with over 300 specimens in 1763 and, until his appointment as Surgeon to St George's in 1768, was heavily involved in the examination of this and other material, as well as in studies of foetal testicular descent, placental circulation, the nature of pus and lymphatic circulation. In 1772 he commenced lecturing on the theory and practice of surgery, and in 1776 he was appointed Surgeon-Extraordinary to George III.He is rightly regarded as the founder of scientific surgery, but his knowledge was derived almost entirely from his own experiments and observations. His contemporaries did not always accept or understand the concepts which led to such aphorisms as, "to perform an operation is to mutilate a patient we cannot cure", and his written comment to his pupil Jenner: "Why think. Why not trie the experiment". His desire to establish the aetiology of gonorrhoea led to him infecting himself, as a result of which he also contracted syphilis. His ensuing account of the characteristics of the disease remains a classic of medicine, although it is likely that the sequelae of the condition brought about his death at a relatively early age. From 1773 he suffered recurrent anginal attacks of such a character that his life "was in the hands of any rascal who chose to annoy and tease him". Indeed, it was following a contradiction at a board meeting at St George's that he died.By 1788, with the death of Percival Pott, he had become unquestionably the leading surgeon in Britain, if not Europe. Elected to the Royal Society in 1767, the extraordinary variety of his collections, investigations and publications, as well as works such as the "Treatise on the natural history of the human teeth" (1771–8), gives testimony to his original approach involving the fundamental and inescapable relation of structure and function in both normal and disease states. The massive growth of his collections led to his acquiring two houses in Golden Square to contain them. It was his desire that after his death his collection be purchased and preserved for the nation. It contained 13,600 specimens and had cost him £70,000. After considerable delay, Par-liament voted inadequate sums for this purpose and the collection was entrusted to the recently rechartered Royal College of Surgeons of England, in whose premises this remarkable monument to the omnivorous and eclectic activities of this outstanding figure in the evolution of medicine and surgery may still be seen. Sadly, some of the collection was lost to bombing during the Second World War. His surviving papers were also extensive, but it is probable that many were destroyed in the early nineteenth century.[br]Principal Honours and DistinctionsFRS 1767.
