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 :. | Study of the proportion of the head | Raffaello Sanzio named Raffael Portrat of Lorenzo de Medici | The Annunciation | The Annunciation | Lady with Ermine |

William Woodward
(1 May 1859 - 17 November 1939) was a U.S. artist and educator, best known for his impressionist paintings of New Orleans and the Gulf Coast of the United States. Woodward was born in Seekonk, Massachusetts. His younger brother Ellsworth Woodward also became a notable artist. William Woodward studied art at the Rhode Island School of Design, and later at the Academie Julian where he received instruction from Gustave Boulanger and Jules Lefebvre. View of the Napoleon House in New Orleans, 1904In 1884 Woodward was hired to teach fine art, mechanical drawing, and architectural drawing at Tulane University in New Orleans. He became interested in the history and architecture of the city, especially the old French Quarter, which at the time had become largely neglected with many of the historic structures in a state of decay. In 1895 he led a successful campaign to save the Cabildo from demolition. His series of paintings of French Quarter scenes helped shape awareness of the neighborhood's architectural heritage and spurred the formation of the Vieux Carre Commission to help preserve it. He started teaching architectural engineering at Tulane in 1894 and helped found the Tulane School of Architecture in 1907, as well as the Newcomb School of Art. In 1921 he suffered an accident and used a wheelchair for the rest of his life. He retired from Tulane the following year, and in 1923 moved to Biloxi, Mississippi. He invented the fiberloid dry etching process. He continued to paint and produce etchings for the rest of his life.
