101 Lavoisier, Antoine Laurent
SUBJECT AREA: Chemical technology[br]b. 26 August 1743 Paris, Franced. 8 May 1794 Paris, France[br]French founder of the modern science of chemistry.[br]As well as receiving a formal education in law and literature, Lavoisier studied science under some of the leading figures of the day. This proved to be an ideal formation of the man in whom "man of science" and "public servant" were so intimately combined. His early work towards the first geological map of France and on the water supply of Paris helped to win him election to the Royal Academy of Sciences in 1768 at the youthful age of 25. In the same year he used some of his private income to buy a part-share in the "tax farm", a private company which leased from the Government the right to collect certain indirect taxes.In 1772 Lavoisier began his researches into the related phenomena of combustion, respiration and the calcination or oxidation of metals. This culminated in the early 1780s in the overthrow of the prevailing theory, based on an imponderable combustion principle called "phlogiston", and the substitution of the modern explanation of these processes. At the same time, understanding of the nature of acids, bases and salts was placed on a sounder footing. More important, Lavoisier defined a chemical element in its modern sense and showed how it should be applied by drawing up the first modern list of the chemical elements. With the revolution in chemistry initiated by Lavoisier, chemists could begin to understand correctly the fundamental processes of their science. This understanding was the foundationo of the astonishing advance in scientific and industrial chemistry that has taken place since then. As an academician, Lavoisier was paid by the Government to carry out investigations into a wide variety of practical questions with a chemical bias, such as the manufacture of starch and the distillation of phosphorus. In 1775 Louis XVI ordered the setting up of the Gunpowder Commission to improve the supply and quality of gunpowder, deficiencies in which had hampered France's war efforts. Lavoisier was a member of the Commission and, as usual, took the leading part, drawing up its report and supervising its implementation. As a result, the industry became profitable, output increased so that France could even export powder, and the range of the powder increased by two-thirds. This was a material factor in France's war effort in the Revolution and the Napoleonic wars.As if his chemical researches and official duties were not enough, Lavoisier began to apply his scientific principles to agriculture when he purchased an estate at Frechines, near Blois. After ten years' work on his experimental farm there, Lavoisier was able to describe his results in the memoir "Results of some agricultural experiments and reflections on their relation to political economy" (Paris, 1788), which holds historic importance in agriculture and economics. In spite of his services to the nation and to humanity, his association with the tax farm was to have tragic consequences: during the reign of terror in 1794 the Revolutionaries consigned to the guillotine all the tax farmers, including Lavoisier.[br]Bibliography1862–93, Oeuvres de Lavoisier, Vols I–IV, ed.

102 Russell, John Scott
SUBJECT AREA: Ports and shipping[br]b. 9 May 1808 Parkhead, near Glasgow, Scotlandd. 8 June 1882 Isle of Wight, England[br]Scottish engineer, naval architect and academic.[br]A son of the manse, Russell was originally destined for the Church and commenced studies at the University of St Andrews, but shortly afterwards he transferred to Glasgow, graduating MA in 1825 when only 17 years old. He began work as a teacher in Edinburgh, working up from a school to the Mechanics Institute and then in 1832 to the University, where he took over the classes in natural philosophy following the death of the professor. During this period he designed and advised on the application of steam power to road transport and to the Forth and Clyde Canal, thereby awakening his interest in ships and naval architecture.Russell presented papers to the British Association over several years, and one of them, The Wave Line Theory of Ship Form (although now superseded), had great influence on ship designers of the time and helped to establish the formal study of hydromechanics. With a name that was becoming well known, Russell looked around for better opportunities, and on narrowly missing appointment to the Chair of Mathematics at Edinburgh University he joined the upand-coming Clyde shipyard of Caird \& Co., Greenock, as Manager in 1838.Around 1844 Russell and his family moved to London; following some business problems he was in straitened circumstances. However, appointment as Secretary to the Committee setting up the Great Exhibition of 1851 eased his path into London's intellectual society and allowed him to take on tasks such as, in 1847, the purchase of Fairbairn's shipyard on the Isle of Dogs and the subsequent building there of I.K. Brunel's Great Eastern steamship. This unhappy undertaking was a millstone around the necks of Brunel and Russell and broke the health of the former. With the yard failing to secure the order for HMS Warrior, the Royal Navy's first ironclad, Russell pulled out of shipbuilding and for the remainder of his life was a designer, consultant and at times controversial, but at all times polished and urbane, member of many important committees and societies. He is remembered as one of the founders of the Institution of Naval Architects in 1860. His last task was to design a Swiss Lake steamer for Messrs Escher Wyss, a company that coincidentally had previously retained Sir William Fairbairn.[br]Principal Honours and DistinctionsFRS 1847.BibliographyJohn Scott Russell published many papers under the imprint of the British Association, the Royal Society of Arts and the Institution of Naval Architects. His most impressive work was the mammoth three-volume work on shipbuilding published in London in 1865 entitled The Modern System of Naval Architecture. Full details and plans of the Great Eastern are included.Further ReadingG.S.Emmerson, 1977, John Scott Russell, a Great Victorian Engineer and Naval Architect, London: MurrayFMW
