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 :. | Studies for a Nativity | Christ's Head | Madonna of the Rocks | Mona Lisa | The Annunciation |

George Inness
1825-1894 George Inness Galleries George Inness (May 1, 1825 -August 3, 1894), was an American landscape painter; born in Newburgh, New York; died at Bridge of Allan in Scotland. His work was influenced, in turn, by that of the old masters, the Hudson River school, the Barbizon school, and, finally, by the theology of Emanuel Swedenborg, whose spiritualism found vivid expression in the work of Inness' maturity. He is best known for these mature works that helped define the Tonalist movement. Inness was the fifth of thirteen children born to John Williams Inness, a farmer, and his wife, Clarissa Baldwin. His family moved to Newark, New Jersey when he was about five years of age. In 1839 he studied for several months with an itinerant painter, John Jesse Barker. In his teens, Inness worked as a map engraver in New York City. During this time he attracted the attention of French landscape painter Regis François Gignoux, with whom he subsequently studied. Throughout the mid-1840s he also attended classes at the National Academy of Design, and studied the work of Hudson River School artists Thomas Cole and Asher Durand; "If", Inness later recalled thinking, "these two can be combined, I will try." Concurrent with these studies Inness opened his first studio in New York. In 1849 Inness married Delia Miller, who died a few months later. The next year he married Elizabeth Abigail Hart, with whom he would have six children.

From 1883 to 1885, he studied with Peder Severin Krøyer at the Independent Study Schools, then debuted in the Charlottenborg Exhibition in the spring of 1885 with Portrait of a Young Girl (his sister, Anna; Pierre Auguste Renoir is reported to have admired this painting). Hammershøi married Ida Ilsted in 1891.
