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 :. | anna sjalv tredje | Last Supper | Madonna Litta ey | Portrats of two men | Unfinished painting of St. Jerome in the Wilderness |

Miller, Alfred Jacob
American Painter, 1810-1874 American painter. From 1831-2 he studied with the portrait painter Thomas Sully in Philadelphia, PA. In 1832 he went to France, where he studied in Paris at the Ecole des Beaux-Arts. He also visited Rome before returning to Baltimore, to open a portrait studio in 1834. Three years later Miller moved to New Orleans, LA, and was engaged by Captain William Drummond Stewart to accompany an expedition to the Rocky Mountains. The journey brought Miller into close contact with the American Indians, whose hunting and social customs he depicted in 200 watercolour sketches, and with the Far West fur trappers at their annual trading gatherings. He was one of the first artists to leave a detailed visual account of the life of the American mountain men (see WILD WEST AND FRONTIER ART). Miller's Rocky Mountain paintings are among the most romantic images of the American West ever created. His works are often panoramic and dramatic, yet he was equally adept at depicting charming, intimate scenes. His free, vigorous painting style brings to life both the American Indian and the rugged pioneer. Such paintings as the Lost Greenhorn
Gustave Le Gray
French Photographer, 1820-1884,French photographer, painter and teacher. He studied painting with Paul Delaroche until 1843. A study trip to Switzerland and Italy, financed by his parents, followed, but it was cut short by an untimely marriage in 1844, his sudden return to his family's home and the subsequent birth of two children in 1845 and 1846. Skilled in painting as an experimenter with pigments, he was attracted to the experimental side of the new paper negative processes available in France after 1847 and plunged into photography, probably to finance the burdens of the family life newly thrust upon him. His treatise, Trait? pratique de photographie sur papier et sur verre (1850), outlined his own variant of the dry waxed paper negative process using thinner paper, as well as a recipe for collodion on glass negatives rivalling that of the English inventor Frederick Scott Archer (see PHOTOGRAPHY,
