    [br]
    English chemist, founder of coal-tar chemistry.
    [br]
    Mansfield, the son of a country clergyman, was educated privately at first, then at Winchester College and at Cambridge; ill health, which dogged his early years, delayed his graduation until 1846. He was first inclined to medicine, but after settling in London, chemistry seemed to him to offer the true basis of the grand scheme of knowledge he aimed to establish. After completing the chemistry course at the Royal College of Chemistry in London, he followed the suggestion of its first director, A.W.von Hofmann, of investigating the chemistry of coal tar. This work led to a result of great importance for industry by demonstrating the valuable substances that could be extracted from coal tar. Mansfield obtained pure benzene, and toluene by a process for which he was granted a patent in 1848 and published in the Chemical Society's journal the same year The following year he published a pamphlet on the applications of benzene.
    Blessed with a private income, Mansfield had no need to support himself by following a regular profession. He was therefore able to spread his brilliant talents in several directions instead of confining them to a single interest. During the period of unrest in 1848, he engaged in social work with a particular concern to improve sanitation. In 1850, a description of a balloon machine in Paris led him to study aeronautics for a while, which bore fruit in an influential book, Aerial Navigation (London, 1851). He then visited Paraguay, making a characteristically thorough and illuminating study of conditions there. Upon his return to London in 1853, Mansfield resumed his chemical studies, especially on salts. He published his results in 1855 as Theory of Salts, his most important contribution to chemical theory.
    Mansfield was in the process of preparing specimens of benzene for the Paris Exhibition of 1855 when a naphtha still overflowed and caught fire. In carrying it to a place of safety, Mansfield sustained injuries which unfortunately proved fatal.

    American chemist, inventor of the electrolytic production of sodium.
    [br]
    Around 1850, the exciting new metal aluminium began to be produced by the process developed by Sainte-Claire Deville. However, it remained expensive on account of the high cost of one of the raw materials, sodium. It was another thirty years before Castner became the first to work successfully the process for producing sodium, which consisted of heating sodium hydroxide with charcoal at a high temperature. Unable to interest American backers in the process, Castner took it to England and set up a plant at Oldbury, near Birmingham. At the moment he achieved commercial success, however, the demand for cheap sodium plummeted as a result of the development of the electrolytic process for producing aluminium. He therefore sought other uses for cheap sodium, first converting it to sodium peroxide, a bleaching agent much used in the straw-hat industry. Much more importantly, Castner persuaded the gold industry to use sodium instead of potassium cyanide in the refining of gold. With the "gold rush", he established a large market in Australia, the USA, South Africa and elsewhere, but the problem was to meet the demand, so Castner turned to the electrolytic method. At first progress was slow because of the impure nature of the sodium hydroxide, so he used a mercury cathode, with which the released sodium formed an amalgam. It then reacted with water in a separate compartment in the cell to form sodium hydroxide of a purity hitherto unknown in the alkali industry; chlorine was a valuable by-product.
    In 1894 Castner began to seek international patents for the cell, but found he had been anticipated in Germany by Kellner, an Austrian chemist. Preferring negotiation to legal confrontation, Castner exchanged patents and processes with Kellner, although the latter's had been less successful. The cell became known as the Castner-Kellner cell, but the process needed cheap electricity and salt, neither of which was available near Oldbury, so he set up the Castner-Kellner Alkali Company works at Runcorn in Cheshire; at the same time, a pilot plant was set up in the USA at Saltville, Virginia, with a larger plant being established at Niagara Falls.

    b. 8 April 1818 Giessen, Germany
    d. 2 May 1892 Berlin, Germany
    [br]
    German organic chemist.
    [br]
    The son of an architect, Hofmann began studying law and languages but was increasingly drawn to chemistry, attracted by Liebig's teaching at Giessen. In 1841 Hofmann took his doctorate with a study of coal tar. He became Privatdozent at Bonn University in 1845, but later that year he was persuaded to take up the post of first Director of the Royal College of Chemistry in London, after tenure was guaranteed as a result of Prince Albert's influence. He remained there for twenty years until he was offered professorships in chemistry at Bonn and Berlin. He accepted the latter. Hofmann continued the method of teaching chemistry, based on laboratory instruction, developed by Liebig at Giessen, and extended it to England and Berlin. A steady stream of well-trained chemists issued forth from Hofmann's tuition, concerning themselves especially with experimental organic chemistry and the industrial applications of chemistry. In 1848 one of his students, C.B. Mansfield, devised the method of fractional distillation of coal tar, to separate pure benzene, xylene and toluene, thus laying the foundations of the coal-tar industry. In 1856 another student, W.H. Perkin, prepared the first synthetic dyestuff, aniline purple, heralding the great dyestuffs industry, in which several other of his students distinguished themselves. Although keenly interested in the chemistry of dyestuffs, Hofmann did not pursue their large-scale preparation, but he stressed the importance of scientific research for success on a commercial scale. Hofmann's stimulus in this direction flagged after his return to Germany, and this was a factor in the failure of British industry to follow up their initial advantage and allow it to pass to Germany. In 1862 Hofmann prepared a dye from a derivative of triphenylmethane, which he called rosaniline. From this he derived a series of beautiful colours, ranging from blue to violet, which he patented as "Hofmann's violets" the following year.

    d. 14 July 1907 Sudbury, England
    [br]
    English chemist, discoverer of aniline dyes, the first synthetic dyestuffs.
    [br]
    He early showed an aptitude for chemistry and in 1853 entered the Royal College of Chemistry as a student under A.W.von Hofmann, the first Professor at the College. By the end of his first year, he had carried out his first piece of chemical research, on the action of cyanogen chloride on phenylamine, which he published in the Journal of the Chemical Society (1857). He became honorary assistant to von Hofmann in 1857; three years previously he had set up his own chemical laboratory at home, where he had discovered the first of the azo dyes, aminoazonapththalene. In 1856 Perkin began work on the synthesis of quinine by oxidizing a salt of allyl toluidine with potassium dichromate. Substituting aniline, he obtained a dark-coloured precipitate which proved to possess dyeing properties: Perkin had discovered the first aniline dye. Upon receiving favourable reports on the new material from manufacturers of dyestuffs, especially Pullars of Perth, Perkin resigned from the College and turned to the commercial exploitation of his discovery. This proved highly successful. From 1858, the dye was manufactured at his Greenford Green works as "Aniline Purple" or "Tyrian Purple". It was later to be referred to by the French as mauve. Perkin's discovery led to the development of the modern dyestuffs industry, supplanting dyes from the traditional vegetable sources. In 1869, he introduced two new methods for making the red dye alizarin, in place of the process that involved the use of the madder plant (Rubia tinctorum). In spite of German competition, he dominated the British market until the end of 1873. After eighteen years in chemical industry, Perkin retired and devoted himself entirely to the pure chemical research which he had been pursuing since the 1850s. He eventually contributed ninety papers to the Chemical Society and further papers to other bodies, including the Royal Society. For example, in 1867 he published his synthesis of unsaturated organic acids, known as "Perkin's synthesis". Other papers followed, on the structure of "Aniline Purple". In 1881 Perkin drew attention to the magnetic-rotatory power of some of the substances he had been dealing with. From then on, he devoted particular attention to the application of this phenomenon to the determination of chemical structure.
    Perkin won wide recognition for his discoveries and other contributions to chemistry.
    The half-centenary of his great discovery was celebrated in July 1906 and later that year he received a knighthood.

    b. 21 February 1791 Great Harwood, Lancashire, England
    d. 30 November 1866 Oakenshaw, Lancashire, England
    [br]
    English pioneer in textile chemistry.
    [br]
    Mercer began work at the age of 9 as a bobbinwinder and then a hand-loom weaver. He had no formal education in chemistry but taught himself and revealed remarkable ability in both theoretical and applied aspects of the subject. He became the acknowledged "father of textile chemistry" and the Royal Society elected him Fellow in 1850. His name is remembered in connection with the lustrous "mercerized" cotton which, although not developed commercially until 1890, arose from his discovery, c. 1844, of the effect of caustic soda on cotton linters. He also discovered that cotton could be dissolved in a solution of copper oxide in ammonia, a phenomenon later exploited in the manufacture of artificial silk. As a youth, Mercer experimented at home with dyeing processes and soon acquired sufficient skill to set up as an independent dyer. Most of his working life was, however, spent with the calico-printing firm of Oakenshaw Print Works in which he eventually became a partner, and it was there that most of his experimental work was done. The association was a very appropriate one, for it was a member of this firm's staff who first recognized Mercer's potential talent and took the trouble in his spare time to teach him reading, writing and arithmetic. Mercer developed manganese-bronze colours and researched into catalysis and the ferrocyanides. Among his innovations was the chlorination of wool in order to make it print as easily as cotton. It was many years later that it was realized that this treatment also conferred valuable shrink-resisting qualities. Becoming interested in photochemistry, he devised processes for photographic printing on fabric. Queen Victoria was presented with a handkerchief printed in this way when she visited the Great Exhibition of 1851, of which Mercer was a juror. A photograph of Mercer himself on cloth is preserved in the Museum of Science and Industry in Manchester. He presented papers to the British Association and was a member of the Chemical Society.

    [br]
    American chemist, inventor of nylon.
    [br]
    After graduating in chemistry, Carothers embarked on academic research at several universities, finally at Harvard University. His earliest published papers, from 1923, heralded the brilliance and originality of his later work. In 1928, Du Pont de Nemours persuaded him to forsake the academic world to lead their new organic-chemistry group in a programme of fundamental research at their central laboratories at Wilmington, Delaware. The next nine years were extraordinarily productive, yielding important contributions to theoretical organic chemistry and the foundation of two branches of chemical industry, namely the production of synthetic rubber and of wholly synthetic fibres.
    Carothers began work on high molecular weight substances yielding fibres and introduced polymerization by condensation: polymerization by addition was already known. He developed a clear understanding of the relation between the repeating structural units in a large molecule and its physical chemical properties. In 1931, Carothers found that chloroprene could be polymerized much faster than isoprene, the monomer in natural rubber. This process yielded polychloroprene or neoprene, a synthetic rubber with improved properties. Manufacture began the following year, and the material has continued to be used for speciality rubbers.
    There followed many publications announcing new condensations polymers. On 2 January 1935, he obtained a patent for the formation of new polyamides, including one from adipic acid and hexamethylenediamene. After four years of development work, which cost Du Pont some $27 million, this new polyamide, or nylon, reached the stage of commercial production, beginning on 23 October 1938. Nylon stockings appeared the following year and 64 million were sold during the first twelve months. However, Carothers saw none of this spectacular success: he had died by his own hand in 1937, after a long history of gradually intensifying depression.

    d. 15 April 1935 Hove, England
    [br]
    English chemist who contributed to the development of viscose rayon from cellulose.
    [br]
    Cross was educated at the universities of London, Zurich and Manchester. It was at Owens College, Manchester, that Cross first met E.J. Bevan and where these two first worked together on the nature of cellulose. After gaining some industrial experience, Cross joined Bevan to set up a partnership in London as analytical and consulting chemists, specializing in the chemistry and technology of cellulose and lignin. They were at the Jodrell laboratory, Kew Gardens, for a time and then set up their own laboratory at Station Avenue, Kew Gardens. In 1888, the first edition of their joint publication A Textbook of Paper-making, appeared. It went into several editions and became the standard reference and textbook on the subject. The long introductory chapter is a discourse on cellulose.
    In 1892, Cross, Bevan and Clayton Beadle took out their historic patent on the solution and regeneration of cellulose. The modern artificial-fibre industry stems from this patent. They made their discovery at New Court, Carey Street, London: wood-pulp (or another cheap form of cellulose) was dissolved in a mixture of carbon disulphide and aqueous alkali to produce sodium xanthate. After maturing, it was squirted through fine holes into dilute acid, which set the liquid to give spinnable fibres of "viscose". However, it was many years before the process became a commercial operation, partly because the use of a natural raw material such as wood involved variations in chemical content and each batch might react differently. At first it was thought that viscose might be suitable for incandescent lamp filaments, and C.H.Stearn, a collaborator with Cross, continued to investigate this possibility, but the sheen on the fibres suggested that viscose might be made into artificial silk. The original Viscose Spinning Syndicate was formed in 1894 and a place was rented at Erith in Kent. However, it was not until some skeins of artificial silk (a term to which Cross himself objected) were displayed in Paris that textile manufacturers began to take an interest in it. It was then that Courtaulds decided to investigate this new fibre, although it was not until 1904 that they bought the English patents and developed the first artificial silk that was later called "rayon". Cross was also concerned with the development of viscose films and of cellulose acetate, which became a rival to rayon in the form of "Celanese". He retained his interest in the paper industry and in publishing, in 1895 again collaborating with Bevan and publishing a book on Cellulose and other technical articles. He was a cultured man and a good musician. He was elected a Fellow of the Royal Society in 1917.

    b. 28 November 1837 Starkey, New York, USA
    d. 10 May 1920 Short Hills, New Jersey, USA
    [br]
    American inventor and the first successful manufacturer of celluloid.
    [br]
    Leaving school at the age of 16, Hyatt spent ten years in the printing trade, demonstrating meanwhile a talent for invention. The offer of a prize of $10,000 for finding a substitute for ivory billiard balls stimulated Hyatt to experiment with various materials. After many failures, he arrived at a composition of paper flock, shellac and collodion, which was widely adopted. Noting the "skin" left after evaporating collodion, he continued his experiments, using nitrocellulose as a base for plastic materials, yet he remained largely ignorant of both chemistry and the dangers of this explosive substance. Independently of Parkes in England, he found that a mixture of nitrocellulose, camphor and a little alcohol could, by heating, be made soft enough to mould but became hard at room temperature. Hyatt's first patent for the material, celluloid, was dated 12 July 1870 (US pat. 105338) and was followed by many others for making domestic and decorative articles of celluloid, replacing more expensive natural materials. Manufacture began at Albany in the winter of 1872–3. In 1881 Hyatt and his brother Isiah Smith floated the Hyatt Pure Water Company. By introducing purifying coagulants into flowing water, they avoided the expense and delay of allowing the water to settle in large tanks before filtration. Many towns and paper and woollen mills adopted the new process, and in 1891 it was introduced into Europe. During 1891–2, Hyatt devised a widely used type of roller bearing. Later inventions included a sugar-cane mill, a multistitch sewing machine and a mill for the cold rolling and straightening of steel shafts. It was characteristic of Hyatt's varied inventions that they achieved improved results at less expense.

    English engineer who set up the first water-powered textile mill in Britain at Derby.
    [br]
    At the beginning of the eighteenth century, silk weaving was one of the most prosperous trades in Britain, but it depended upon raw silk worked up on hand twisting or throwing machines. In 1702 Thomas Cotchett set up a mill for twisting silk by water-power at the northern end of an island in the river Derwent at Derby; this would probably have been to produce organzine, the hard twisted thread used for the warp when weaving silk fabrics. Such mills had been established in Italy beginning with the earliest in Bologna in 1272, but it would appear that Cotchett used Dutch silk-throwing machinery that was driven by a water wheel that was 13½ ft (4.1 m) in diameter and built by the local engineer, George Sorocold. The enterprise soon failed, but it was quickly revived and extended by Thomas and John Lombe with machinery based on that being used successfully in Italy.

    Scottish industrial chemist.

    Spence was first apprenticed to a grocer and then joined his uncle's business. When that failed, he found work in a Dundee gasworks. During his spare time he had been studying chemistry, and in 1834 he established a small chemical works in London, which was none too successful. It was after a move to Burgh, near Carlisle, that his prospects brightened, with an improved method for making alum, a substance much used in the dyeing and textile industries. Spence obtained a patent in 1845 for extracting the substance from alum-containing shale by treating the burned shale and iron pyrites with sulphuric acid. He set up a plant at Pendleton, near Manchester, and enlarged the scale of his operation to become the largest manufacturer of alum in the world. The most profitable product was a crude form of alum known as aluminoferric. This came to be much in demand by the paper industry and in the treatment of sewage, an activity of growing importance in mid-Victorian Britain.
    Not all of Spence's ventures met with success; his attempts to exploit the phosphate deposits on the island of Redmonds in the West Indies lost heavily. He was an active citizen of Manchester, with a strongly Nonconformist tendency. He supported the cause against atmospheric pollution, although he himself was successfully prosecuted for pollution from his alum works at Pendleton; that prompted a move to Miles Platting, also near Manchester. In 1900, his firm became part of Laporte Industries Ltd.

    b. 7 May 1807 Hurlet, between Paisley and Glasgow, Scotland
    d. 13 August 1897
    [br]
    British developer of the wool-combing machine.
    [br]
    Isaac Holden's father, who had the same name, had been a farmer and lead miner at Alston in Cumbria before moving to work in a coal-mine near Glasgow. After a short period at Kilbarchan grammar school, the younger Isaac was engaged first as a drawboy to two weavers and then, after the family had moved to Johnstone, Scotland, worked in a cotton-spinning mill while attending night school to improve his education. He was able to learn Latin and bookkeeping, but when he was about 15 he was apprenticed to an uncle as a shawl-weaver. This proved to be too much for his strength so he returned to scholastic studies and became Assistant to an able teacher, John Kennedy, who lectured on physics, chemistry and history, which he also taught to his colleague. The elder Isaac died in 1826 and the younger had to provide for his mother and younger brother, but in 1828, at the age of 21, he moved to a teaching post in Leeds. He filled similar positions in Huddersfield and Reading, where in October 1829 he invented and demonstrated the lucifer match but did not seek to exploit it. In 1830 he returned because of ill health to his mother in Scotland, where he began to teach again. However, he was recommended as a bookkeeper to William Townend, member of the firm of Townend Brothers, Cullingworth, near Bingley, Yorkshire. Holden moved there in November 1830 and was soon involved in running the mill, eventually becoming a partner.
    In 1833 Holden urged Messrs Townend to introduce seven wool-combing machines of Collier's designs, but they were found to be very imperfect and brought only trouble and loss. In 1836 Holden began experimenting on the machines until they showed reasonable success. He decided to concentrate entirely on developing the combing machine and in 1846 moved to Bradford to form an alliance with Samuel Lister. A joint patent in 1847 covered improvements to the Collier combing machine. The "square motion" imitated the action of the hand-comber more closely and was patented in 1856. Five more patents followed in 1857 and others from 1858 to 1862. Holden recommended that the machines should be introduced into France, where they would be more valuable for the merino trade. This venture was begun in 1848 in the joint partnership of Lister \& Holden, with equal shares of profits. Holden established a mill at Saint-Denis, first with Donisthorpe machines and then with his own "square motion" type. Other mills were founded at Rheims and at Croix, near Roubaix. In 1858 Lister decided to retire from the French concerns and sold his share to Holden. Soon after this, Holden decided to remodel all their machinery for washing and carding the gill machines as well as perfecting the square comb. Four years of excessive application followed, during which time £20,000 was spent in experiments in a small mill at Bradford. The result fully justified the expenditure and the Alston Works was built in Bradford.
    Holden was a Liberal and from 1865 to 1868 he represented Knaresborough in Parliament. Later he became the Member of Parliament for the Northern Division of the Riding, Yorkshire, and then for the town of Keighley after the constituencies had been altered. He was liberal in his support of religious, charitable and political objectives. His house at Oakworth, near Keighley, must have been one of the earliest to have been lit by electricity.

  • 13 Nobel, Alfred Bernhard

    [br]
    b. 21 October 1833 Stockholm, Sweden
    d. 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".

  • 15 Bennett, Charles Harper

    [br]
    b. 1840 Clapham, London, England
    d. 1927 Sydney, Australia
    [br]
    English inventor of the "ripening" technique for increasing the sensitivity of gelatine silver halide emulsions.
    [br]
    The son of a hatter, Bennett studied medicine and was interested in mechanical devices, chemistry and later photography. An interior view shown at a South London Photographic Society meeting in March 1878 prompted requests for details of Bennett's procedure, and these were published almost immediately. It involved heating gelatine silver bromide for extremely long periods with an excess of silver bromide. The resulting emulsion had greatly enhanced sensitivity. This "ripening" process proved to be a major advance in the development of modern photographic emulsions. It was not patented and was soon widely adopted. Bennett's process became a key factor in the establishment of a new industry, the mass production of gelatine dry plates.

    [br]
    b. 28 January 1811 Vauxhall, London, England
    d. 29 November 1911 Gravesend (?), Kent, England
    [br]
    English contributor to the development of efficient hydraulic cements.
    [br]
    As a young man Johnson studied both chemistry and physics and gained some experience in the manufacture of cement before joining the firm of John Bazely White as Works Manager at Swanscombe in Kent in 1838. He spent some years investigating the production processes and left the firm to set up on his own in 1851 on the Limehouse Reach of the River Medway, moving later to Gateshead on the River Tyne. Johnson produced a cement that was a great improvement on that of Parker and of Frost: like William Aspdin (see Aspdin, Joseph), he made a true Portland cement by mixing chalk, clay and water, and then clinkering the mixture. He used local clay at Gateshead and had the chalk shipped from the Thames area. In 1872 Johnson patented an improved bottle kiln, called the Johnson Chamber Kiln; it was of horizontal design, which speeded up manufacturing processes.

  • 19 Staudinger, Hermann

    [br]
    b. 23 March 1881 Worms, Germany
    d. 8 September 1965 Freiberg im Breisgau, Germany
    [br]
    German chemist, founder of polymer chemistry.
    [br]
    Staudinger studied chemistry at the universities of Halle, Darmstadt and Munich, originally as a preparation for botanical studies, but chemistry claimed his full attention. He followed an academic career, with professorships at Karlsruhe in 1908, Zurich in 1912 and Freiberg from 1926 until his retirement in 1951. Staudinger began his work as an organic chemist by following well-established lines of research, but from 1920 he struck out in a new direction. Until that time, rubber and other apparently non-crystalline materials with high molecular weight were supposed to consist of a disordered collection of small molecules. Staudinger investigated the structure of rubber and realized that it was made up of very large molecules with many basic groups of atoms held together by normal chemical bonds. Substances formed in this way are known as "polymers". Staudinger's views first met with opposition, but he developed methods of determining the molecular weights of these "high polymers". Finally, the introduction of X-ray crystallographic investigation of chemical structure confirmed his views. This discovery has proved to be the basis of a new branch of chemistry with momentous consequences for industry. From it stemmed the synthetic rubber, plastics, fibres, adhesives and other industries, with all their multifarious applications in everyday life. The Staudinger equation, linking viscosity with molecular weight, is still widely used, albeit with some reservations, in the polymer industry.
    During the 1930s, Staudinger turned his attention to biopolymers and foresaw the discovery some twenty years later that these macromolecules were the building blocks of life. In 1953 he belatedly received the Nobel Prize in Chemistry.
