115 Guinand, Pierre Louis
SUBJECT AREA: Photography, film and optics[br]b. 20 April 1748 Brenets, Neuchâtel, Switzerlandd. 13 February 1824 Brenets, Neuchâtel, Switzerland[br]Swiss optical glassmaker.[br]Guinand received little formal education and followed his father's trade of joiner. He specialized in making clock cases, but after learning how to cast metals he took up the more lucrative work of making watch cases. When he was about 20 years old, in a customer's house he caught sight of an English telescope, a rarity in a Swiss mountain village. Intrigued, he obtained permission to examine it. This aroused his interest in optical matters and he began making spectacles and small telescopes.Achromatic lenses were becoming known, their use being to remove the defect of chromatic aberration or coloured optical images, but there remained defects due to imperfections in the glass itself. Stimulated by offers of prizes by scientific bodies, including the Royal Society of London, for removing these defects, Guinand set out to remedy them. He embarked in 1784 on a long and arduous series of experiments, varying the materials and techniques for making glass. The even more lucrative trade of making bells for repeaters provided the funds for a furnace capable of holding 2 cwt (102 kg) of molten glass. By 1798 or so he had succeeded in making discs of homogeneous glass. He impressed the famous Parisian astronomer de Lalande with them and his glass became well enough known for scientists to visit him. In 1805 Fraunhofer persuaded Guinand to join his optical-instrument works at Benediktheurn, in Bavaria, to make lenses. After nine years, Guinand returned to Brenets with a pension, on condition he made no more glass and disclosed no details of his methods. After two years these conditions had become irksome and he relinquished the pension. On 19 February 1823 Guinand described his discoveries in his classic "Memoir on the making of optical glass, more particularly of glass of high refractive index for use in the production of achromatic lenses", presented to the Société de Physique et d'Histoire Naturelle de Genève. This gives details of his experiments and investigations and discusses a suitable pot-clay stirrer and stirring mechanism for the molten glass, with temperature control, to overcome optical-glass defects such as bubbles, seeds, cords and colours. Guinand was hailed as the man in Europe who had achieved this and has thus rightly been called the founder of the era of optical glassmaking.[br]Further ReadingThe fullest account in English of Guinand's life and work is 'Some account of the late M. Guinand and of the discovery made by him in the manufacture of flint glass for large telescopes by F.R., extracted from the Bibliothèque Universelle des Sciences, trans.C.F.de B.', Quart.J.Sci.Roy.Instn.Lond.

117 Rosenhain, Walter
SUBJECT AREA: Metallurgy[br]b. 24 August 1875 Berlin, Germanyd. 17 March 1934 Kingston Hill, Surrey, England[br]German metallurgist, first Superintendent of the Department of Metallurgy and Metallurgical Chemistry at the National Physical Laboratory, Teddington, Middlesex.[br]His family emigrated to Australia when he was 5 years old. He was educated at Wesley College, Melbourne, and attended Queen's College, University of Melbourne, graduating in physics and engineering in 1897. As an 1851 Exhibitioner he then spent three years at St John's College, Cambridge, under Sir Alfred Ewing, where he studied the microstructure of deformed metal crystals and abandoned his original intention of becoming a civil engineer. Rosenhain was the first to observe the slip-bands in metal crystals, and in the Bakerian Lecture delivered jointly by Ewing and Rosenhain to the Royal Society in 1899 it was shown that metals deformed plastically by a mechanism involving shear slip along individual crystal planes. From this conception modern ideas on the plasticity and recrystallization of metals rapidly developed. On leaving Cambridge, Rosenhain joined the Birmingham firm of Chance Brothers, where he worked for six years on optical glass and lighthouse-lens systems. A book, Glass Manufacture, written in 1908, derives from this period, during which he continued his metallurgical researches in the evenings in his home laboratory and published several papers on his work.In 1906 Rosenhain was appointed Head of the Metallurgical Department of the National Physical Laboratory (NPL), and in 1908 he became the first Superintendent of the new Department of Metallurgy and Metallurgical Chemistry. Many of the techniques he introduced at Teddington were described in his Introduction to Physical Metallurgy, published in 1914. At the outbreak of the First World War, Rosenhain was asked to undertake work in his department on the manufacture of optical glass. This soon made it possible to manufacture optical glass of high quality on an industrial scale in Britain. Much valuable work on refractory materials stemmed from this venture. Rosenhain's early years at the NPL were, however, inseparably linked with his work on light alloys, which between 1912 and the end of the war involved virtually all of the metallurgical staff of the laboratory. The most important end product was the well-known "Y" Alloy (4% copper, 2% nickel and 1.5% magnesium) extensively used for the pistons and cylinder heads of aircraft engines. It was the prototype of the RR series of alloys jointly developed by Rolls Royce and High Duty Alloys. An improved zinc-based die-casting alloy devised by Rosenhain was also used during the war on a large scale for the production of shell fuses.After the First World War, much attention was devoted to beryllium, which because of its strength, lightness, and stiffness would, it was hoped, become the airframe material of the future. It remained, however, too brittle for practical use. Other investigations dealt with impurities in copper, gases in aluminium alloys, dental alloys, and the constitution of alloys. During this period, Rosenhain's laboratory became internationally known as a centre of excellence for the determination of accurate equilibrium diagrams.[br]Principal Honours and DistinctionsFRS 1913.
