After Koenig and Bauer had introduced the machine printing-press and returned to Germany, it fell to Applegath and his mechanic brother-in-law Edward Cooper to effect improvements. In particular, Applegath succeeded Koenig and Bauer as machine specialist to The Times newspaper, then in the vanguard of printing technology.

Applegath and Cooper first came into prominence when the Bank of England began to seek ways of reducing the number of forged banknotes. In 1816 Cooper patented a device for printing banknotes from curved stereotypes fixed to a cylinder. These were inked and printed by the rotary method. Although Applegath and Cooper were granted money to develop their invention, the Bank did not pursue it. The idea of rotary printing was interesting, but it was not followed up, possibly due to lack of demand.

Applegath and Cooper were then engaged by John Walter of The Times to remedy defects in Koenig and Bauer's presses; in 1818 Cooper patented an improved method of inking the forme and Applegath also took out patents for improvements. In 1821 Applegath had enough experience of these presses to set up as a manufacturer of printing machinery in premises in Duke Street, Blackfriars, in London. Increases in the size and circulation of The Times led Walter to ask Applegath to build a faster press. In 1827 he produced a machine with the capacity of four presses, his steam-driven four-feeder press.

Its flat form carrying the type passed under four impression cylinders in a row. It could make 4,200 impressions an hour and sufficed to print The Times for twenty years, until it was superseded by the rotary press devised by Hoe. By 1826, however, Applegath was in financial difficulties; he sold his Duke Street workshop to William Clowes, a book printer. In the following year he gave up being a full-time manufacturer of printing machinery and turned to silk printing. In 1830 he patented a machine for printing rolls of calico and silk from bent intaglio plates.

In 1848 Applegath was persuaded by The Times to return to newspaper printing. He tackled rotary printing without the benefit of curved printing plates and roll paper feed, and he devised a large "type revolving" machine which set the pattern for newspaper printing-presses for some twenty years.

He began his working life in banking but soon went into glassmaking and in 1829 he moved to London to open a glass warehouse. On hearing of the first practicable photographic processes in 1834, Claudet visited Paris, where he received instruction in the daguerreotype process from the inventor Daguerre, and purchased a licence to operate in England. On returning to London he began to sell daguerreotype views of Paris and Rome, but was soon taking and selling his own views of London. At this time exposures could take as long as thirty minutes and portraiture from life was impracticable. Claudet was fascinated by the possibilities of the daguerreotype and embarked on experiments to improve the process. In 1841 he published details of an accelerated process and took out a patent proposing the use of flat painted backgrounds and a red light in dark-rooms. In June of that year Claudet opened the second daguerreotype portrait studio in London, just three months after his rival, Richard Beard. He took stereoscopic photographs for Wheatstone as early as 1842, although it was not until the 1850s that stereoscopy became a major interest. He suggested and patented several improvements to viewers derived from Brewster's pattern.

Claudet was also one of the first photographers to practise professionally Talbot's calotype process. He became a personal friend of Talbot, one of the few from whom the inventor was prepared to accept advice. Claudet died suddenly in London following an accident that occurred when he was alighting from an omnibus. A memoir produced shortly after his death lists over forty scientific papers relating to his researches into photography.

The name of Le Corbusier is synonymous with the International style of modern architecture and city planning, one utilizing functionalist designs carried out in twentieth-century materials with modern methods of construction. Charles-Edouard Jeanneret, born in the watch-making town of La Chaux-de-Fonds in the Jura mountain region, was the son of a watch engraver and dial painter. In the years before 1918 he travelled widely, studying building in many countries. He learned about the use of reinforced concrete in the studio of Auguste Perret and about industrial construction under Peter Behrens. In 1917 he went to live in Paris and spent the rest of his life in France; in 1920 he adopted the name of Le Corbusier, one derived from that of his ancestors (Le Corbesier), and ten years later became a French citizen.

Le Corbusier's long working life spanned a career divided into three distinct parts. Between 1905 and 1916 he designed a number of simple and increasingly modern houses; the years 1921 to 1940 were ones of research and debate; and the twenty years from 1945 saw the blossoming of his genius. After 1917 Le Corbusier gained a reputation in Paris as an architect of advanced originality. He was particularly interested in low-cost housing and in improving accommodation for the poor. In 1923 he published Vers une architecture, in which he planned estates of mass-produced houses where all extraneous and unnecessary features were stripped away and the houses had flat roofs and plain walls: his concept of "a machine for living in". These white boxes were lifted up on stilts, his pilotis, and double-height living space was provided internally, enclosed by large areas of factory glazing. In 1922 Le Corbusier exhibited a city plan, La Ville contemporaine, in which tall blocks made from steel and concrete were set amongst large areas of parkland, replacing the older concept of city slums with the light and air of modern living. In 1925 he published Urbanisme, further developing his socialist ideals. These constituted a major reform of the industrial-city pattern, but the ideas were not taken up at that time. The Depression years of the 1930s severely curtailed architectural activity in France. Le Corbusier designed houses for the wealthy there, but most of his work prior to 1945 was overseas: his Centrosoyus Administration Building in Moscow (1929–36) and the Ministry of Education Building in Rio de Janeiro (1943) are examples. Immediately after the end of the Second World War Le Corbusier won international fame for his Unité d'habitation theme, the first example of which was built in the boulevard Michelet in Marseille in 1947–52. His answer to the problem of accommodating large numbers of people in a small space at low cost was to construct an immense all-purpose block of pre-cast concrete slabs carried on a row of massive central supports. The Marseille Unité contains 350 apartments in eight double storeys, with a storey for shops half-way up and communal facilities on the roof. In 1950 he published Le Modular, which described a system of measurement based upon the human male figure. From this was derived a relationship of human and mathematical proportions; this concept, together with the extensive use of various forms of concrete, was fundamental to Le Corbusier's later work. In the world-famous and highly personal Pilgrimage Church of Notre Dame du Haut at Ronchamp (1950–5), Le Corbusier's work was in Expressionist form, a plastic design in massive rough-cast concrete, its interior brilliantly designed and lit. His other equally famous, though less popular, ecclesiastical commission showed a contrasting theme, of "brutalist" concrete construction with uncompromisingly stark, rectangular forms. This is the Dominican Convent of Sainte Marie de la Tourette at Eveux-sur-l'Arbresle near Lyon, begun in 1956. The interior, in particular, is carefully worked out, and the lighting, from both natural and artificial sources, is indirect, angled in many directions to illuminate vistas and planes. All surfaces are carefully sloped, the angles meticulously calculated to give optimum visual effect. The crypt, below the raised choir, is painted in bright colours and lit from ceiling oculi.

One of Le Corbusier's late works, the Convent is a tour de force.
