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 :. | Annunciation (detail) sg77 | Lady with Ermine | The Portinari Altarpiece | The Virgin and Child with St Anne (detail) f | Reverse side of the portrait of Ginevra de' Benci |

Paul Revere
American Sculptor and Engraver, 1735-1818 was an American silversmith and a patriot in the American Revolution. Because he was glorified after his death for his role as a messenger in the battles of Lexington and Concord, Revere's name and his "midnight ride" are well-known in the United States as a patriotic symbol. In his lifetime, Revere was a prosperous and prominent Boston craftsman, who helped organize an intelligence and alarm system to keep watch on the British military. Revere later served as an officer in one of the most disastrous campaigns of the American Revolutionary War, a role for which he was later exonerated. After the war, he was early to recognize the potential for large-scale manufacturing of metal.

William Powell Frith
English Painter, 1819-1909 His parents were in domestic employment before taking a hotel in Harrogate in 1826. They encouraged him to become an artist, despite his own desire to be an auctioneer. While at school in Dover, Frith sketched caricatures and copies of Dutch genre scenes (Dover Mus.) that betray his disposition to narratives. His taste did not accord with the academic training he received at Henry Sass's Academy in London (1835-7) and at the Royal Academy Schools (1837). Frith began his career as a portrait painter, using members of his family as models. He first exhibited at the British Institution in 1838, and during the 1840s he established himself with his entertaining historical and literary subjects in the popular tradition of C. R. Leslie, William Mulready and Sir David Wilkie. He was a member of THE CLIQUE, which included Richard Dadd, Augustus Egg, Henry O'Neil and John Phillip.
