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 :. | Portrait of Mona Lisa,La Gioconda (mk05) | The Annunciation | Madonna of the Rocks | Adoration of the Magi | The Last Supper |

Lesser Ury
1861 - 1931 was a German Impressionist painter and printmaker. He was born Leo Lesser Ury in Birnbaum, the son of a baker whose death in 1872 was followed by the Ury family's move to Berlin. In 1878 Lesser left school to apprentice with a tradesman, and the next year he went to D??sseldorf to study painting at the Kunstakademie. Ury spent time in Brussels, Paris, Stuttgart, and other locations, before returning to Berlin in 1887. His first exhibition was in 1889 and met with a hostile reception, although he was championed by Adolph von Menzel whose influence induced the Academie to award Ury a prize. In 1893 he joined the Munich Secession, one of the several Secessions formed by progressive artists in Germany and Austria in the last years of the 19th century. In 1901 he returned to Berlin, where he exhibited with the Berlin Secession, first in 1915 and notably in 1922, when he had a major exhibition. By this time Ury's critical reputation had grown and his paintings and pastels were in demand. His subjects were landscapes, urban landscapes, and interior scenes, treated in an Impressionistic manner that ranged from the subdued tones of figures in a darkened interior to the effects of streetlights at night to the dazzling light of foliage against the summer sky. Ury is especially noted for his paintings of nocturnal cafe scenes and rainy streets. He developed a habit of repeating these compositions in order to sell them while retaining the originals, and these quickly made and inferior copies have harmed his reputation.
