Italian High Renaissance Painter and Inventor, 1452-1519 Italian High Renaissance Painter and Inventor, 1452-1519 Florentine Renaissance man, genius, artist in all media, architect, military engineer. Possibly the most brilliantly creative man in European history, he advertised himself, first of all, as a military engineer. In a famous letter dated about 1481 to Ludovico Sforza, of which a copy survives in the Codice Atlantico in Milan, Leonardo asks for employment in that capacity. He had plans for bridges, very light and strong, and plans for destroying those of the enemy. He knew how to cut off water to besieged fortifications, and how to construct bridges, mantlets, scaling ladders, and other instruments. He designed cannon, very convenient and easy of transport, designed to fire small stones, almost in the manner of hail??grape- or case-shot (see ammunition, artillery). He offered cannon of very beautiful and useful shapes, quite different from those in common use and, where it is not possible to employ cannon ?? catapults, mangonels and trabocchi and other engines of wonderful efficacy not in general use. And he said he made armoured cars, safe and unassailable, which will enter the serried ranks of the enemy with their artillery ?? and behind them the infantry will be able to follow quite unharmed, and without any opposition. He also offered to design ships which can resist the fire of all the heaviest cannon, and powder and smoke. The large number of surviving drawings and notes on military art show that Leonardo claims were not without foundation, although most date from after the Sforza letter. Most of the drawings, including giant crossbows (see bows), appear to be improvements on existing machines rather than new inventions. One exception is the drawing of a tank dating from 1485-8 now in the British Museum??a flattened cone, propelled from inside by crankshafts, firing guns. Another design in the British Museum, for a machine with scythes revolving in the horizontal plane, dismembering bodies as it goes, is gruesomely fanciful. Most of the other drawings are in the Codice Atlantico in Milan but some are in the Royal Libraries at Windsor and Turin, in Venice, or the Louvre and the École des Beaux Arts in Paris. Two ingenious machines for continuously firing arrows, machine-gun style, powered by a treadmill are shown in the Codice Atlantico. A number of other sketches of bridges, water pumps, and canals could be for military or civil purposes: dual use technology. Leonardo lived at a time when the first artillery fortifications were appearing and the Codice Atlantico contains sketches of ingenious fortifications combining bastions, round towers, and truncated cones. Models constructed from the drawings and photographed in Calvi works reveal forts which would have looked strikingly modern in the 19th century, and might even feature in science fiction films today. On 18 August 1502 Cesare Borgia appointed Leonardo as his Military Engineer General, although no known building by Leonardo exists. Leonardo was also fascinated by flight. Thirteen pages with drawings for man-powered aeroplanes survive and there is one design for a helicoidal helicopter. Leonardo later realized the inadequacy of the power a man could generate and turned his attention to aerofoils. Had his enormous abilities been concentrated on one thing, he might have invented the modern glider.   Related Paintings of LEONARDO da Vinci :. | The Madonna of the Carnation (detail) dg | Small devotional picture by Verrocchio | The madonna with the Children | The Last Supper | the last supper |

Johan Gustaf Sandberg, född 1782, död 1854, var målare; han var professor i teckning vid Konstakademien från 1828, och direktör där 1845?C1853. Sandberg ägnade sig främst åt historiemåleri, med motiv ur nordisk mytologi och svensk historia. Hans främsta verk inom detta område är kalkmålningarna över Gustav Vasa i Uppsala domkyrka. Han målade också en mängd porträtt. Sandberg blev 1794 elev i konstakademins principskola och 1801 i antikskolan, lärde samtidigt musik och klaverspelning och tjänade pengar genom lektioner och genom arbete på kungliga teaterns dekorationsmålarverkstad. Under den följande tiden slöt han sig till den opposition mot akademin, som hade sin medelpunkt i "Sällskapet för konststudium". Tvisten med akademin lade sig snart, Sandberg valdes till ledamot 1821 och blev ordinarie professor 1828. Däremot hade han aldrig tillfälle att göra den för äldre tiders konstnärer obligatoriska studieresan till södern. Han utförde teckningarna till praktverket "Ett år i Sverige" (1827 -35) med bilderna graverade under Christian Didrik Forssells ledning och texten skriven av Anders Abraham Grafström. Under upprepade sommarvistelser på Säfstaholms slott målade Sandberg folktyper och folkdräkter. Åtskilliga porträtt utförde Sandberg för det praktfulla "Galleri af utmärkta svenska lärde, vetenskapsidkare och konstnärer", som han utgav 1835?C42 (100 porträtt, litograferade av J. Cardon).

Edwin John Victor Pasmore (3 December 1908 - 23 January 1998) was a British artist and architect. He pioneered the development of abstract art in Britain in the 1940s and 1950s. Pasmore was born in Chelsham, Surrey. He studied at Harrow but with the death of his father in 1927 he was forced to take an administrative job at the London County Council. He studied painting part-time at the Central School of Art and was associated with the formation of the Euston Road School and the first post-war exhibition of abstract art. After experimenting with abstraction Pasmore worked for a time in a lyrical figurative style, painting views of the Thames from Hammersmith much in the style of Turner and Whistler. Beginning in 1947 he developed a purely abstract style under the influence of Ben Nicholson and other artists associated with Circle, becoming a pioneering figure of the revival of interest in Constructivism in Britain following the War. Pasmore's abstract work, often in collage and construction of reliefs, pioneered the use of new materials and was sometimes on a large architectural scale. Herbert Read described Pasmore's new style as 'The most revolutionary event in post-war British art'. Pasmore's abstract Mural for the canteen of a bus depot in Kingston upon Thames 1950Pasmore was a leading figure in the promotion of abstract art and reform of the fine art education system. From 1943-1949 he taught at Camberwell School of Art where one of his students was Terry Frost whom he advised not to bother with the School's formal teaching and to instead study the works in the National Gallery. In 1950 he was commissioned to design an abstract mural for a bus depot in Kingston upon Thames and the following year Pasmore contributed a mural to the Festival of Britain that promoted a number of the British Constructivists. From 1952 he was leader of the art course of Kings College, Durham based in Newcastle upon Tyne. There he developed a general art and design course inspired by the 'basic course' of the Bauhaus that became the model for higher arts education across the UK. Pasmore was a supporter of fellow artist Richard Hamilton, giving him a teaching job in Newcastle and contributing a constructivist structure to the exhibition "This Is Tomorrow" in collaboration with Ernő Goldfinger and Helen Phillips. Pasmore was commissioned to make a mural for the new Newcastle Civic Centre. His interest in the synthesis of art and architecture was given free hand when he was appointed Consulting Director of Architectural Design for Peterlee development corporation in 1955. Pasmore's choices in this area proved controversial; the centerpiece of the town design became an abstract public art structure of his design, the Apollo Pavilion. The structure became the focus for local criticism over the failures of the Development Corporation but Pasmore remained a defender of his work, returning to the town to face critics of the Pavilion at a public meeting in 1982. Pasmore represented Britain at the 1961 Venice Biennale, was participating artist at the documenta II 1959 in Kassel and was a trustee of the Tate Gallery, donating a number of works to the collection. He gave a lecture on J.M.W.Turner as 'first of the moderns' to the Turner Society, of which he was elected a vice president in 1975.
