After working as a millwright in Halifax, Riley found employment at the Ormesby Ironworks in Middlesbrough until, in 1869, he became manager of the Askam Ironworks in Cumberland. Three years later, in 1872, he was appointed Blast-furnace Manager at the pioneering Siemens Steel Company's works at Landore, near Swansea in South Wales. Using Spanish ore, he produced the manganese-rich iron (spiegeleisen) required as an additive to make satisfactory steel. Riley was promoted in 1874 to be General Manager at Landore, and he worked with William Siemens to develop the use of the latter's regenerative furnace for the production of open-hearth steel. He persuaded Welsh makers of tin plate to use sheets rolled from lowcarbon (mild) steel instead of from charcoal iron and, partly by publishing some test results, he was instrumental in influencing the Admiralty to build two naval vessels of mild steel, the Mercury and the Iris.

In 1878 Riley moved north on his appointment as General Manager of the Steel Company of Scotland, a firm closely associated with Charles Tennant that was formed in 1872 to make steel by the Siemens process. Already by 1878, fourteen Siemens melting furnaces had been erected, and in that year 42,000 long tons of ingots were produced at the company's Hallside (Newton) Works, situated 8 km (5 miles) south-east of Glasgow. Under Riley's leadership, steelmaking in open-hearth furnaces was initiated at a second plant situated at Blochairn. Plates and sections for all aspects of shipbuilding, including boilers, formed the main products; the company also supplied the greater part of the steel for the Forth (Railway) Bridge. Riley was associated with technical modifications which improved the performance of steelmaking furnaces using Siemens's principles. He built a gasfired cupola for melting pig-iron, and constructed the first British "universal" plate mill using three-high rolls (Lauth mill).

At the request of French interests, Riley investigated the properties of steels containing various proportions of nickel; the report that he read before the Iron and Steel Institute in 1889 successfully brought to the notice of potential users the greatly enhanced strength that nickel could impart and its ability to yield alloys possessing substantially lower corrodibility.

The Steel Company of Scotland paid dividends in the years to 1890, but then came a lean period. In 1895, at the age of 54, Riley moved once more to another employer, becoming General Manager of the Glasgow Iron and Steel Company, which had just laid out a new steelmaking plant at Wishaw, 25 km (15 miles) south-east of Glasgow, where it already had blast furnaces. Still the technical innovator, in 1900 Riley presented an account of his experiences in introducing molten blast-furnace metal as feed for the open-hearth steel furnaces. In the early 1890s it was largely through Riley's efforts that a West of Scotland Board of Conciliation and Arbitration for the Manufactured Steel Trade came into being; he was its first Chairman and then its President.

In 1899 James Riley resigned from his Scottish employment to move back to his native Yorkshire, where he became his own master by acquiring the small Richmond Ironworks situated at Stockton-on-Tees. Although Riley's 1900 account to the Iron and Steel Institute was the last of the many of which he was author, he continued to contribute to the discussion of papers written by others.

Samuel Fox was the son of a weaver's shuttle maker in the hamlet of Bradwell (probably Bradfield, near Sheffield) in the remote hills. He went to Sheffield and served an apprenticeship in the steel trade. Afterwards, he worked with great energy and industry until he acquired sufficient capital to start in business on his own account at Stocksbridge, near Sheffield. It was there that he invented what became known as "Fox's Paragon Frame" for umbrellas. Whalebone or solid steel had previously been used for umbrella ribs, but whalebone was unreliable and steel was heavy. Fox realized that if he grooved the ribs he could make them both lighter and more elastic. In his first patent, taken out in 1852, he described making the ribs and stretchers of parasols and umbrellas from a narrow strip of steel plate partially bent into a trough-like form. He took out five more patents. The first, in 1853, was for strengthening the joints. His next two, in 1856 and 1857, were more concerned with preparing the steel for making the ribs. Another patent in 1857 was basically for improving the formation of the bit at the end of the rib where it was fixed to the stretcher and where the end of the rib has to be formed into a boss: this was so it could have a pin fixed through it to act as a pivot when the umbrella has to be opened or folded and yet support the rib and stretcher. The final patent, in 1865, reverted once more to improving the manufacture of the ribs. He made a fortune before other manufacturers knew what he was doing. Fox established a works at Lille when he found that the French import duties and other fiscal arrangements hindered exporting umbrellas and successful trading there, and was thereby able to develop a large and lucrative business.

Of Dutch descent, Hunstman was apprenticed to a clockmaker at Epworth, Lincolnshire. In 1725 he set up in Doncaster as a maker of clocks, locks and roasting jacks. He made improvements in his tools but found himself hampered by the poor quality of the steel available, then made by the cementation process, which yielded a steel with a non-uniform carbon content. Around 1740, Huntsman moved to Handsworth, now part of Sheffield, and began experimenting by heating varying compositions of fuel and flux with crude steel in a crucible, to obtain a steel of uniform composition. During the years 1745 to 1750 he attained his object, but not without many unsuccessful "heats", as excavations of the site of his works now reveal. Although his steel was far better than that previously available, however, the conservative cutlers of Sheffield rejected it, claiming it was too hard to work; therefore Huntsman exported his product to France, where the cutlers promptly worked it into high-quality knives and razors that were exported to England. The Sheffield cutlers' attempts to prevent Huntsman from exporting his steel proved unsuccessful. Huntsman did not patent his process, preferring to retain his advantage by shrouding his work in secrecy, carrying out his melting at night to escape observation, but a rival cutler, Samuel Walker, gained admittance to Huntsman's works disguised as a tramp seeking food. As a result, Walker was able to make crucible steel at a handsome profit. Huntsman fought back and earned success through the sheer quality of his steel, and had to move to.a larger site at Attercliffe in 1770. Crucible steelmaking remained important through the nineteenth century although, as it was a small-scale process, its application was restricted to engineers' cutting tools and the cutting edges of certain tools.

Hadfield's father, Robert, set up a steelworks in Sheffield in 1872, one of the earliest to specialize in steel castings. After his education in Sheffield, during which he showed an interest in chemistry, Hadfield entered his father's works. His first act was to set up a laboratory, where he began systematically experimenting with alloy steels in order to improve the quality of the products of the family firm. In 1883 Hadfield found that by increasing the manganese content to 12.5 per cent, with a carbon content of 1.4 per cent, the resulting alloy showed extraordinary resistance to abrasive wear even though it was quite soft. It was soon applied in railway points and crossings, crushing and grinding machinery, and wherever great resistance to wear is required. Its lack of brittleness led to its use in steel helmets during the First World War. Hadfield's manganese steel was also non-magnetic, which was later of importance in the electrical industry. Hadfield's other great invention was that of silicon steel. Again after careful and systematic laboratory work, Hadfield found that a steel containing 3–4 per cent silicon and as little as possible of other elements was highly magnetic, which was to prove important in the electrical industry (e.g. reducing the weight and bulk of electrical transformers). Hadfield took over the firm on the death of his father in 1888, but he continued to lay great stress on the need for laboratory research to improve the quality and range of products. The steel-casting side of the business led to a flourishing armaments industry, and this, together with their expertise in alloy steels, made Hadfield's one of the great names in Sheffield and British steel until, sadly, it succumbed along with so many other illustrious names during the British economic recession of 1983. Hadfield had a keen interest in metallurgical history, particularly in his characteristically thorough examination of the alloys of iron prepared by Faraday at the Royal Institution. Hadfield was an enlightened employer and was one of the first to introduce the eight-hour day.

The most valuable part of Bessemer's education took place in the workshop of his inventor father. At the age of only 17 he went to London to seek his fortune and set himself up in the trade of casting art works in white metal. He went on to the embossing of metals and other materials and this led to his first major invention, whereby a date was incorporated in the die for embossing seals, thus preventing the wholesale forgeries that had previously been committed. For this, a grateful Government promised Bessemer a paid position, a promise that was never kept; recognition came only in 1879 with a belated knighthood. Bessemer turned to other inventions, mainly in metalworking, including a process for making bronze powder and gold paint. After he had overcome technical problems, the process became highly profitable, earning him a considerable income during the forty years it was in use.

The Crimean War presented inventors such as Bessemer with a challenge when weaknesses in the iron used to make the cannon became apparent. In 1856, at his Baxter House premises in St Paneras, London, he tried fusing cast iron with steel. Noticing the effect of an air current on the molten mixture, he constructed a reaction vessel or converter in which air was blown through molten cast iron. There was a vigorous reaction which nearly burned the house down, and Bessemer found the iron to be almost completely decarburized, without the slag threads always present in wrought iron. Bessemer had in fact invented not only a new process but a new material, mild steel. His paper "On the manufacture of malleable iron and steel without fuel" at the British Association meeting in Cheltenham later that year created a stir. Bessemer was courted by ironmasters to license the process. However, success was short-lived, for they found that phosphorus in the original iron ore passed into the metal and rendered it useless. By chance, Bessemer had used in his trials pig-iron, derived from haematite, a phosphorus-free ore. Bessemer tried hard to overcome the problem, but lacking chemical knowledge he resigned himself to limiting his process to this kind of pig-iron. This limitation was removed in 1879 by Sidney Gilchrist Thomas, who substituted a chemically basic lining in the converter in place of the acid lining used by Bessemer. This reacted with the phosphorus to form a substance that could be tapped off with the slag, leaving the steel free from this harmful element. Even so, the new material had begun to be applied in engineering, especially for railways. The open-hearth process developed by Siemens and the Martin brothers complemented rather than competed with Bessemer steel. The widespread use of the two processes had a revolutionary effect on mechanical and structural engineering and earned Bessemer around £1 million in royalties before the patents expired.

Joseph Whitworth received his early education in a school kept by his father, but from the age of 12 he attended a school near Leeds. At 14 he joined his uncle's mill near Ambergate, Derbyshire, to learn the business of cotton spinning. In the four years he spent there he realized that he was more interested in the machinery than in managing a cotton mill. In 1821 he obtained employment as a mechanic with Crighton \& Co., Manchester. In 1825 he moved to London and worked for Henry Maudslay and later for the Holtzapffels and Joseph Clement. After these years spent gaining experience, he returned to Manchester in 1833 and set up in a small workshop under a sign "Joseph Whitworth, Tool Maker, from London".

The business expanded steadily and the firm made machine tools of all types and other engineering products including steam engines. From 1834 Whitworth obtained many patents in the fields of machine tools, textile and knitting machinery and road-sweeping machines. By 1851 the company was generally regarded as the leading manufacturer of machine tools in the country. Whitworth was a pioneer of precise measurement and demonstrated the fundamental mode of producing a true plane by making surface plates in sets of three. He advocated the use of the decimal system and made use of limit gauges, and he established a standard screw thread which was adopted as the national standard. In 1853 Whitworth visited America as a member of a Royal Commission and reported on American industry. At the time of the Crimean War in 1854 he was asked to provide machinery for manufacturing rifles and this led him to design an improved rifle of his own. Although tests in 1857 showed this to be much superior to all others, it was not adopted by the War Office. Whitworth's experiments with small arms led on to the construction of big guns and projectiles. To improve the quality of the steel used for these guns, he subjected the molten metal to pressure during its solidification, this fluid-compressed steel being then known as "Whitworth steel".

In 1868 Whitworth established thirty annual scholarships for engineering students. After his death his executors permanently endowed the Whitworth Scholarships and distributed his estate of nearly half a million pounds to various educational and charitable institutions. Whitworth was elected an Associate of the Institution of Civil Engineers in 1841 and a Member in 1848 and served on its Council for many years. He was elected a Member of the Institution of Mechanical Engineers in 1847, the year of its foundation.

The name Joseph Gillott became synonymous with pen making at a time when the basic equipment for writing was undergoing a change. The quill pen had served writers for centuries, but attempts had been made since the seventeenth century to improve on it. The first major technical development was the steel nib, which began to be made c.1829. The steel nib was still little known in Birmingham in 1839, but ten years later it was in common use. Its stiffness was at first a drawback, but Gillott was among the first to improve its flexibility by introducing three slots, which later became standard practice. Mechanical methods of manufacture made the pen cheaper and improved its quality. In 1840 Gillott issued a "precept" informing the public that he was pen maker to the Queen and that he had been manufacturing pens for twenty years at his Victoria Works in Birmingham. He announced the successful reception by the public of his new patent pen. There were also special "warranted school" pens designed for the various grades of writing taught in schools. Finally, he warned against inferior imitations and recommended the public to buy only those pens stamped with his name.

Born Carl Wilhelm, he attended craft schools in Lübeck and Magdeburg, followed by an intensive course in natural science at Göttingen as a pupil of Weber. At the age of 19 Siemens travelled to England and sold an electroplating process developed by his brother Werner Siemens to Richard Elkington, who was already established in the plating business. From 1843 to 1844 he obtained practical experience in the Magdeburg works of Count Stolburg. He settled in England in 1844 and later assumed British nationality, but maintained close contact with his brother Werner, who in 1847 had co-founded the firm Siemens \& Halske in Berlin to manufacture telegraphic equipment. William began to develop his regenerative principle of waste-heat recovery and in 1856 his brother Frederick (1826–1904) took out a British patent for heat regeneration, by which hot waste gases were passed through a honeycomb of fire-bricks. When they became hot, the gases were switched to a second mass of fire-bricks and incoming air and fuel gas were led through the hot bricks. By alternating the two gas flows, high temperatures could be reached and considerable fuel economies achieved. By 1861 the two brothers had incorporated producer gas fuel, made by gasifying low-grade coal.

Heat regeneration was first applied in ironmaking by Cowper in 1857 for heating the air blast in blast furnaces. The first regenerative furnace was set up in Birmingham in 1860 for glassmaking. The first such furnace for making steel was developed in France by Pierre Martin and his father, Emile, in 1863. Siemens found British steelmakers reluctant to adopt the principle so in 1866 he rented a small works in Birmingham to develop his open-hearth steelmaking furnace, which he patented the following year. The process gradually made headway; as well as achieving high temperatures and saving fuel, it was slower than Bessemer's process, permitting greater control over the content of the steel. By 1900 the tonnage of open-hearth steel exceeded that produced by the Bessemer process.

In 1872 Siemens played a major part in founding the Society of Telegraph Engineers (from which the Institution of Electrical Engineers evolved), serving as its first President. He became President for the second time in 1878. He built a cable works at Charlton, London, where the cable could be loaded directly into the holds of ships moored on the Thames. In 1873, together with William Froude, a British shipbuilder, he designed the Faraday, the first specialized vessel for Atlantic cable laying. The successful laying of a cable from Europe to the United States was completed in 1875, and a further five transatlantic cables were laid by the Faraday over the following decade.

The Siemens factory in Charlton also supplied equipment for some of the earliest electric-lighting installations in London, including the British Museum in 1879 and the Savoy Theatre in 1882, the first theatre in Britain to be fully illuminated by electricity. The pioneer electric-tramway system of 1883 at Portrush, Northern Ireland, was an opportunity for the Siemens company to demonstrate its equipment.

The son of a commercial photographer, Anschütz entered the business in 1868 and developed an interest in the process of instantaneous photography. The process was very difficult with the contemporary wet-plate process, but with the introduction of the much faster dry plates in the late 1870s he was able to make progress. Anschütz designed a focal plane shutter capable of operating at speeds up to 1/1000 of a second in 1883, and patented his design in 1888. it involved a vertically moving fabric roller-blind that worked at a fixed tension but had a slit the width of which could be adjusted to alter the exposure time. This design was adopted by C.P.Goerz, who from 1890 manufactures a number of cameras that incorporated it.

Anschütz's action pictures of flying birds and animals attracted the attention of the Prussian authorities, and in 1886 the Chamber of Deputies authorized financial support for him to continue his work, which had started at the Hanover Military Institute in October 1885. Inspired by the work of Eadweard Muybridge in America, Anschütz had set up rows of cameras whose focal-plane shutters were released in sequence by electromagnets, taking twenty-four pictures in about three-quarters of a second. He made a large number of studies of the actions of people, animals and birds, and at the Krupp artillery range at Meppen, near Essen, he recorded shells in flight. His pictures were reproduced, and favourably commented upon, in scientific and photographic journals.

To bring the pictures to the public, in 1887 he created the Electro-Tachyscope. The sequence negatives were printed as 90 x 120 mm transparencies and fixed around the circumference of a large steel disc. This was rotated in front of a spirally wound Geissler tube, which produced a momentary brilliant flash of light when a high voltage from an induction coil was applied to it, triggered by contacts on the steel disc. The flash duration, about 1/1000 of a second, was so short that it "froze" each picture as it passed the tube. The pictures succeeded each other at intervals of about 1/30 of a second, and the observer saw an apparently continuously lit moving picture. The Electro-Tachyscope was shown publicly in Berlin at the Kulturministerium from 19 to 21 March 1887; subsequently Siemens \& Halske manufactured 100 machines, which were shown throughout Europe and America in the early 1890s. From 1891 his pictures were available for the home in the form of the Tachyscope viewer, which used the principle of the zoetrope: sequence photographs were printed on long strips of thin card, perforated with narrow slots between the pictures. Placed around the circumference of a shallow cylinder and rotated, the pictures could be seen in life-like movement when viewed through the slots.

In November 1894 Anschütz displayed a projector using two picture discs with twelve images each, which through a form of Maltese cross movement were rotated intermittently and alternately while a rotating shutter allowed each picture to blend with the next so that no flicker occurred. The first public shows, given in Berlin, were on a screen 6×8 m (20×26 ft) in size. From 22 February 1895 they were shown regularly to audiences of 300 in a building on the Leipzigstrasse; they were the first projected motion pictures seen in Germany.

The son of a grist miller, Rowland worked in various jobs until 1859 when he established his own business for the construction of wooden and iron steamships and for structural iron works, in Greenpoint, Long Island, New York. In 1860 he founded the Continental Works and during the American Civil War he started manufacturing gun carriages and mortar beds. He fitted out many vessels for the navy, and as a contractor for John Ericsson he built heavily armoured war vessels.

He continued shipbuilding, but later diversified his business. He devoted great attention to the design of gas-works, constructing innovative storage facilities all over the United States, and he was concerned with the improvement of welding iron and steel plates and other processes in the steel industry. In the late 1860s he also began the manufacture of steam-engines and boilers for use in the new but expanding oil industry. In 1869 he took out a patent for a fixed platform for drilling for oil off-shore up to a depth of 15 m (49 ft). With this idea, just ten years after Edwin Drake's success in on-shore oil drilling in Titusville, Pennsylvania, Rowland pioneered the technology of off-shore drilling for petroleum in which the United States later became the leading nation.

John Arnold was apprenticed to his father, a watchmaker, and then worked as an itinerant journeyman in the Low Countries and, later, in England. He settled in London in 1762 and rapidly established his reputation at Court by presenting George III with a miniature repeating watch mounted in a ring. He later abandoned the security of the Court for a more precarious living developing his chronometers, with some financial assistance from the Board of Longitude. Symbolically, in 1771 he moved from the vicinity of the Court at St James's to John Adam Street, which was close to the premises of the Royal Society for the Encouragement of Arts, Manufactures \& Commerce.

By the time Arnold became interested in chronometry, Harrison had already demonstrated that longitude could be determined by means of a timekeeper, and the need was for a simpler instrument that could be sold at an affordable price for universal use at sea. Le Roy had shown that it was possible to dispense with a remontoire by using a detached escapement with an isochronous balance; Arnold was obviously thinking along the same lines, although he may not have been aware of Le Roy's work. By 1772 Arnold had developed his detached escapement, a pivoted detent which was quite different from that used on the European continent, and three years later he took out a patent for a compensation balance and a helical balance spring (Arnold used the spring in torsion and not in tension as Harrison had done). His compensation balance was similar in principle to that described by Le Roy and used riveted bimetallic strips to alter the radius of gyration of the balance by moving small weights radially. Although the helical balance spring was not completely isochronous it was a great improvement on the spiral spring, and in a later patent (1782) he showed how it could be made more truly isochronous by shaping the ends. In this form it was used universally in marine chronometers.

Although Arnold's chronometers performed well, their long-term stability was less satisfactory because of the deterioration of the oil on the pivot of the detent. In his patent of 1782 he eliminated this defect by replacing the pivot with a spring, producing the spring detent escapement. This was also done independendy at about the same time by Berthoud and Earnshaw, although Earnshaw claimed vehemently that Arnold had plagiarized his work. Ironically it was Earnshaw's design that was finally adopted, although he had merely replaced Arnold's pivoted detent with a spring, while Arnold had completely redesigned the escapement. Earnshaw also improved the compensation balance by fusing the steel to the brass to form the bimetallic element, and it was in this form that it began to be used universally for chronometers and high-grade watches.

As a result of the efforts of Arnold and Earnshaw, the marine chronometer emerged in what was essentially its final form by the end of the eighteenth century. The standardization of the design in England enabled it to be produced economically; whereas Larcum Kendall was paid £500 to copy Harrison's fourth timekeeper, Arnold was able to sell his chronometers for less than one-fifth of that amount. This combination of price and quality led to Britain's domination of the chronometer market during the nineteenth century.

Benton spent his childhood in Milwaukee and La Crosse, where he early showed a talent for mechanical invention. His father was a lawyer with an interest in newspapers and who acquired the Milwaukee Daily News. Benton became familiar with typesetting equipment in his father's newspaper office. He learned the printer's trade at another newspaper office, at La Crosse, and later worked as bookkeeper at a type foundry in Milwaukee. When that failed in 1873, Benton acquired the plant, and when he was joined by R.V.Waldo the firm became Benton, Waldo \& Co. Benton began learning and improving type-cutting practice. He first devised unit-width or "self-spacing" type which became popular with compositors, saving, it was reckoned, 20 per cent of their time. Meanwhile, Benton worked on a punch-cutting machine to speed up the process of cutting letters in the steel punches from which matrices or moulds were formed to enable type to be cast from molten metal. His first mechanical punch-cutter worked successfully in 1884. The third machine, patented in 1885, was the model that revolutionized the typefounding operation. So far, punch-cutting had been done by hand, a rare and expensive skill that was insufficient to meet the demands of the new typesetting machines, the monotype of Lanston and the linotype of Merganthaler. These were threatened with failure until Benton saved the day with his automatic punch-cutter. Mechanizing punch-cutting and the forming of matrices made possible the typesetting revolution brought about by mono-and linotype.

In 1892 Benton's firm merged with others to form the American Type Founders Company. Benton's equipment was moved to New York and he with it, to become a board member and Chief Technical Advisor. In 1894 he became Manager of the company's new plant for type manufacture in Jersey City. Benton steadily improved both machinery and processes, for which he was granted twenty patents. With his son Morris Fuller, he was also notable and prolific in the field of type design. Benton remained in active association with his company until just two weeks before his death.

John Deere was the son of a tailor, and first worked as a tanner before becoming apprenticed to a blacksmith. He married Demarius Lamb in 1827, but it appears that competition for blacksmiths was fierce, and the Deere family moved frequently. Two attempts to establish forges ended in fires, and changing partnerships and arguments over debts were to be a feature of Deere's working life. In 1836 John Deere moved west on his own, in an attempt to establish himself. He settled in Grand Detour, Illinois. In this new frontier a blacksmith's skills were sought after, and the blacksmith, with no ready supply of raw materials, had to be able to operate both a furnace for melting metal and a forge for working it. Deere was sufficiently successful for his family to be able to join him. A chance visit to a sawmill and the acquisition of a broken saw blade led to the making of a plough that was to establish John Deere in manufacturing. There were two distinctive features associated with the plough: the soil in the area failed to stick to the steel blade, with obvious benefits to the draught of the implement; and second, the shape of the working mouldboard was square. The reputation that developed with his first three ploughs established that Deere had made the transition from blacksmith to manufacturer.

Over the next decade he had a number of partnerships and eventually set up a factory in Moline, Illinois, in 1848. The following year he sold 2,136 ploughs, and by early 1850 he was producing 350 ploughs per month. Deere was devastated by the loss of his eldest son in the year that the company moved to Moline. However, his second son, Charles, joined him in 1851 and was to be a major influence on the way in which the company developed over the next half-century. The company branched out into the production of cultivators, harrows, drills and wagons. John Deere himself played an active part in the company, but also played an increasing role in public life, with a particular interest in education. The company was incorporated in 1868.

Gilbert travelled widely in Europe before returning to the USA to join the well-known firm of McKim, Mead \& White, for whom he designed the Minnesota State Capitol at Saint Paul (1896–1903). This building, like the majority of Gilbert's work, was in classical form, the great dome modelled on that of Saint Peter's Basilica in Rome. Other designs, on similar classical themes, included his large US Customs House in New York (1907). The structure for which Gilbert is best known, however, was an adaptation of French Gothic style to a sixty-storeyed skyscraper. This was the Woolworth Building, an office tower of romantic silhouette in downtown New York (1913). In contra-distinction to the high-rise designs of Louis Sullivan, who broke new ground in relating the design of the building to the verticality of the structure, Gilbert continued the skyscraper pattern of earlier years by clothing the steel structure in eclectic manner unrelated to the form beneath. The result, if backward-looking, is an elegant, attractive and familiar part of the New York skyline.

s, m., pl. ir: [the etymology of this word has been much contested; some—upon the authority of Snorri, hans menn fóru ‘brynjulausir,’ Hkr. i. 11—derive it from ‘berr’ ( bare) and ‘serkr’ [cp. sark, Scot. for shirt]; but this etymology is inadmissible, because ‘serkr’ is a subst. not an adj.: others derive it from ‘berr’ (Germ. bär = ursus), which is greatly to be preferred, for in olden ages athletes and champions used to wear hides of bears, wolves, and reindeer (as skins of lions in the south), hence the names Bjálfi, Bjarnhéðinn, Úlfhéðinn, (héðinn, pellis,)—‘pellibus aut parvis rhenonum tegimentis utuntur,’ Caes. Bell. Gall. vi. 22: even the old poets understood the name so, as may be seen in the poem of Hornklofi (beginning of 10th century), a dialogue between a Valkyrja and a raven, where the Valkyrja says, at berserkja reiðu vil ek þik spyrja, to which the raven replies, Úlfhéðnar heita, they are called Wolfcoats, cp. the Vd. ch. 9; þeir berserkir er Úlfhéðnar vóru kallaðir, þeir höfðu vargstakka ( coats of wild beasts) fyrir brynjur, Fs. 17]:—a ‘bear-sark,’ ‘bear-coat,’ i. e. a wild warrior or champion of the heathen age; twelve berserkers are mentioned as the chief followers of several kings of antiquity, e. g. of the Dan. king Rolf Krake, Edda 82; a Swed. king, Gautr. S. Fas. iii. 36; king Adils, Hrólf. Kr. S. ch. 16 sqq.; Harald Hárfagri, Eg. ch. 9, Grett. ch. 2, Vd. l. c. (Hornklofi, v. above); the twelve sons of Arngrim, Hervar. S. ch. 3–5, Hdl. 22, 23; the two berserkers sent as a present by king Eric at Upsala to earl Hakon of Norway, and by him presented to an Icel. nobleman, Eb. ch. 25. In battle the berserkers were subject to fits of frenzy, called berserks-gangr (furor bersercicus, cp. the phrase, ganga berserksgang), when they howled like wild beasts, foamed at the mouth and gnawed the iron rim of their shields; during these fits they were, according to popular belief, proof against steel and fire, and made great havoc in the ranks of the enemy; but when the fever abated they were weak and tame. A graphical description of the ‘furor bersercicus’ is found in the Sagas, Yngl. S. ch. 6, Hervar. S. l. c., Eg. ch. 27, 67, Grett. ch. 42, Eb. ch. 25, Nj. ch. 104, Kristni S. ch. 2, 8 (Vd. ch. 46); cp. also a passage in the poem of Hornklofi | grenjuðu berserkir, | guðr var þeim á sinnum, | emjaðu Úlfhéðnar | ok ísarn gniiðu—which lines recall to the mind Roman descriptions of the Cimbric war-cry. In the Icel. Jus Eccles. the berserksgangr, as connected with the heathen age, is liable to the lesser outlawry, K. Þ. K. 78; it is mentioned as a sort of possession in Vd. ch. 37, and as healed by a vow to God. In the Dropl. S. Major (in MS.) it is medically described as a disease (v. the whole extract in the essay ‘De furore Bersercico,’ Kristni S. old Ed. in cake); but this Saga is modern, probably of the first part of the 17th century. The description of these champions has a rather mythical character. A somewhat different sort of berserker is also recorded in Norway as existing in gangs of professional bullies, roaming about from house to house, challenging husbandmen to ‘holmgang’ ( duel), extorting ransom (leysa sik af hólmi), and, in case of victory, carrying off wives, sisters, or daughters; but in most cases the damsel is happily rescued by some travelling Icelander, who fights and kills the berserker. The most curious passages are Glúm, ch. 4, 6, Gísl. ch. 1 (cp. Sir Edm. Head’s and Mr. Dasent’s remarks in the prefaces), Grett. ch. 21, 42, Eg. ch. 67, Flóam. S. ch. 15, 17; according to Grett. ch. 21, these banditti were made outlaws by earl Eric, A. D. 1012. It is worth noticing that no berserker is described as a native of Icel.; the historians are anxious to state that those who appeared in Icel. (Nj., Eb., Kr. S. l. c.) were born Norse (or Swedes), and they were looked upon with fear and execration. That men of the heathen age were taken with fits of the ‘furor athleticus’ is recorded in the case of Thorir in the Vd., the old Kveldulf in Eg., and proved by the fact that the law set a penalty upon it. Berserkr now and then occurs as a nickname, Glúm. 378. The author of the Yngl. S. attributes the berserksgangr to Odin and his followers, but this is a sheer misinterpretation, or perhaps the whole passage is a rude paraphrase of Hm. 149 sqq. In the old Hbl. 37 berserkr and giant are used synonymously. The berserkers are the representatives of mere brute force, and it therefore sounds almost blasphemous, when the Norse Barl. S. speaks of Guðs berserkr (a ‘bear-coat’ or champion of God), (Jesus Kristr gleymdi eigi hólmgöngu sins berserks), 54, 197. With the introduction of Christianity this championship disappeared altogether.
