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 Last Supper-l | Study of a child | Detail of Madonna of the Rocks | The Baptism of Christ | Studies for a Nativity |

Longpre, Paul De
French, practiced mainly in America, 1855-1911 was a French flower painter, actively chiefly in the United States. He was born in Lyons, France, and was entirely self-taught. From his twelfth year he practiced successfully in Paris as a painter of fans. At 21 he first exhibited at the Salon. Having lost his money by the failure of a Paris bank, he moved in 1890 to New York and in 1896 held an exhibition of flower pieces which secured him instant recognition. In 1899 he moved to California and two years later built a beautiful house at Hollywood, which became celebrated for its magnificent flower gardens. De Longpre painted only perfect specimens of flowers; with delicacy of touch and feeling for bosoms he united scientific knowledge, and he also knew how to give expression to the subtle essence of the flowers.
Jean Alaux
(1785 - 2 March 1864) was a French history painter and Director of the French Academy in Rome from 1846-52. Alaux was born in Bordeaux, the son of a painter, and the second of four brothers who were all themselves painters. he received his first lessons in art from his father, but went on to formal training with Pierre Lacour, then Pierre-Narcisse Guerin. He was admitted to the École des Beaux-Arts in Paris in 1807. From 1808 he entered works for the Prix de Rome but his energies were diverted when his elder brother, Jean-Francois Alaux (1783-1858), asked him to help with a large "neorama" (a type of Panorama) he was working on. Jean eventually won the Prix de Rome's first prize in 1815, with a work entitled "Briseis weeping over the body of Patroclus", a scene inspired by The Iliad of Homer. He subsequently became a pensionnaire at the French Academy in Rome from 1816 to 1820 (later becoming its director).
