73 Nobel, Alfred Bernhard
[br]b. 21 October 1833 Stockholm, Swedend. 10 December 1896 San Remo, Italy[br]Swedish industrialist, inventor of dynamite, founder of the Nobel Prizes.[br]Alfred's father, Immanuel Nobel, builder, industrialist and inventor, encouraged his sons to follow his example of inventiveness. Alfred's education was interrupted when the family moved to St Petersburg, but was continued privately and was followed by a period of travel. He thus acquired a good knowledge of chemistry and became an excellent linguist.During the Crimean War, Nobel worked for his father's firm in supplying war materials. The cancellation of agreements with the Russian Government at the end of the war bankrupted the firm, but Alfred and his brother Immanuel continued their interest in explosives, working on improved methods of making nitroglycerine. In 1863 Nobel patented his first major invention, a detonator that introduced the principle of detonation by shock, by using a small charge of nitroglycerine in a metal cap with detonating or fulminating mercury. Two years later Nobel set up the world's first nitroglycerine factory in an isolated area outside Stockholm. This led to several other plants and improved methods for making and handling the explosive. Yet Nobel remained aware of the dangers of liquid nitroglycerine, and after many experiments he was able in 1867 to take out a patent for dynamite, a safe, solid and pliable form of nitroglycerine, mixed with kieselguhr. At last, nitroglycerine, discovered by Sobrero in 1847, had been transformed into a useful explosive; Nobel began to promote a worldwide industry for its manufacture. Dynamite still had disadvantages, and Nobel continued his researches until, in 1875, he achieved blasting gelatin, a colloidal solution of nitrocellulose (gun cotton) in nitroglycerine. In many ways it proved to be the ideal explosive, more powerful than nitroglycerine alone, less sensitive to shock and resistant to moisture. It was variously called Nobel's Extra Dynamite, blasting gelatin and gelignite. It immediately went into production.Next, Nobel sought a smokeless powder for military purposes, and in 1887 he obtained a nearly smokeless blasting powder using nitroglycerine and nitrocellulose with 10 per cent camphor. Finally, a progressive, smokeless blasting powder was developed in 1896 at his San Remo laboratory.Nobel's interests went beyond explosives into other areas, such as electrochemistry, optics and biology; his patents amounted to 355 in various countries. However, it was the manufacture of explosives that made him a multimillionaire. At his death he left over £2 million, which he willed to funding awards "to those who during the preceding year, shall have conferred the greatest benefit on mankind".[br]Bibliography1875, On Modern Blasting Agents, Glasgow (his only book).Further ReadingH.Schuck et al., 1962, Nobel, the Man and His Prizes, Amsterdam.E.Bergengren, 1962, Alfred Nobel, the Man and His Work, London and New York (includes a supplement on the prizes and the Nobel institution).LRD -
74 Nobel, Immanuel
[br]b. 1801 Gävle, Swedend. 3 September 1872 Stockholm, Sweden[br]Swedish inventor and industrialist, particularly noted for his work on mines and explosives.[br]The son of a barber-surgeon who deserted his family to serve in the Swedish army, Nobel showed little interest in academic pursuits as a child and was sent to sea at the age of 16, but jumped ship in Egypt and was eventually employed as an architect by the pasha. Returning to Sweden, he won a scholarship to the Stockholm School of Architecture, where he studied from 1821 to 1825 and was awarded a number of prizes. His interest then leaned towards mechanical matters and he transferred to the Stockholm School of Engineering. Designs for linen-finishing machines won him a prize there, and he also patented a means of transforming rotary into reciprocating movement. He then entered the real-estate business and was successful until a fire in 1833 destroyed his house and everything he owned. By this time he had married and had two sons, with a third, Alfred (of Nobel Prize fame; see Alfred Nobel), on the way. Moving to more modest quarters on the outskirts of Stockholm, Immanuel resumed his inventions, concentrating largely on India rubber, which he applied to surgical instruments and military equipment, including a rubber knapsack.It was talk of plans to construct a canal at Suez that first excited his interest in explosives. He saw them as a means of making mining more efficient and began to experiment in his backyard. However, this made him unpopular with his neighbours, and the city authorities ordered him to cease his investigations. By this time he was deeply in debt and in 1837 moved to Finland, leaving his family in Stockholm. He hoped to interest the Russians in land and sea mines and, after some four years, succeeded in obtaining financial backing from the Ministry of War, enabling him to set up a foundry and arms factory in St Petersburg and to bring his family over. By 1850 he was clear of debt in Sweden and had begun to acquire a high reputation as an inventor and industrialist. His invention of the horned contact mine was to be the basic pattern of the sea mine for almost the next 100 years, but he also created and manufactured a central-heating system based on hot-water pipes. His three sons, Ludwig, Robert and Alfred, had now joined him in his business, but even so the outbreak of war with Britain and France in the Crimea placed severe pressures on him. The Russians looked to him to convert their navy from sail to steam, even though he had no experience in naval propulsion, but the aftermath of the Crimean War brought financial ruin once more to Immanuel. Amongst the reforms brought in by Tsar Alexander II was a reliance on imports to equip the armed forces, so all domestic arms contracts were abruptly cancelled, including those being undertaken by Nobel. Unable to raise money from the banks, Immanuel was forced to declare himself bankrupt and leave Russia for his native Sweden. Nobel then reverted to his study of explosives, particularly of how to adapt the then highly unstable nitroglycerine, which had first been developed by Ascanio Sobrero in 1847, for blasting and mining. Nobel believed that this could be done by mixing it with gunpowder, but could not establish the right proportions. His son Alfred pursued the matter semi-independently and eventually evolved the principle of the primary charge (and through it created the blasting cap), having taken out a patent for a nitroglycerine product in his own name; the eventual result of this was called dynamite. Father and son eventually fell out over Alfred's independent line, but worse was to follow. In September 1864 Immanuel's youngest son, Oscar, then studying chemistry at Uppsala University, was killed in an explosion in Alfred's laboratory: Immanuel suffered a stroke, but this only temporarily incapacitated him, and he continued to put forward new ideas. These included making timber a more flexible material through gluing crossed veneers under pressure and bending waste timber under steam, a concept which eventually came to fruition in the form of plywood.In 1868 Immanuel and Alfred were jointly awarded the prestigious Letterstedt Prize for their work on explosives, but Alfred never for-gave his father for retaining the medal without offering it to him.[br]Principal Honours and DistinctionsImperial Gold Medal (Russia) 1853. Swedish Academy of Science Letterstedt Prize (jointly with son Alfred) 1868.BibliographyImmanuel Nobel produced a short handwritten account of his early life 1813–37, which is now in the possession of one of his descendants. He also had published three short books during the last decade of his life— Cheap Defence of the Country's Roads (on land mines), Cheap Defence of the Archipelagos (on sea mines), and Proposal for the Country's Defence (1871)—as well as his pamphlet (1870) on making wood a more physically flexible product.Further ReadingNo biographies of Immanuel Nobel exist, but his life is detailed in a number of books on his son Alfred.CM -
75 Tizard, Sir Henry Thoms
SUBJECT AREA: Weapons and armour[br]b. 23 August 1885 Gillingham, Kent, Englandd. 9 October 1959 Fareham, Hampshire, England[br]English scientist and administrator who made many contributions to military technology.[br]Educated at Westminster College, in 1904 Tizard went to Magdalen College, Oxford, gaining Firsts in mathematics and chemistry. After a period of time in Berlin with Nernst, he joined the Royal Institution in 1909 to study the colour changes of indicators. From 1911 until 1914 he was a tutorial Fellow of Oriel College, Oxford, but with the outbreak of the First World War he joined first the Royal Garrison Artillery, then, in 1915, the newly formed Royal Flying Corps, to work on the development of bomb-sights. Successively in charge of testing aircraft, a lieutenant-colonel in the Ministry of Munitions and Assistant Controller of Research and Experiments for the Royal Air Force, he returned to Oxford in 1919 and the following year became Reader in Chemical Thermodynamics; at this stage he developed the use of toluene as an air-craft-fuel additive.In 1922 he was appointed an assistant secretary at the government Department of Industrial and Scientific Research, becoming Principal Assistant Secretary in 1922 and its Permanent Director in 1927; during this time he was also a member of the Aeronautical Research Committee, being Chairman of the latter in 1933–43. From 1929 to 1942 he was Rector of Imperial College. In 1932 he was also appointed Chairman of a committee set up to investigate possible national air-defence systems, and it was largely due to his efforts that the radar proposals of Watson-Watt were taken up and an effective system made operational before the outbreak of the Second World War. He was also involved in various other government activities aimed at applying technology to the war effort, including the dam-buster and atomic bombs.President of Magdalen College in 1942–7, he then returned again to Whitehall, serving as Chairman of the Advisory Council on Scientific Policy and of the Defence Research Policy Committee. Finally, in 1952, he became Pro-Chan-cellor of Southampton University.[br]Principal Honours and DistinctionsAir Force Cross 1918. CB 1927. KCB 1937. GCB 1949. American Medal of Merit 1947. FRS 1926.
