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 :. | Studies of children | Madonna with the Yarnwinder after 1510 | The Annunciation | Madonna with the Yarnwinder ty | The Virgin and St Anne (mk08) |

Henry Merwin Shrady
American Sculptor, 1871-1922,was the sculptor of the Ulysses S. Grant Memorial in Washington, D.C. Shrady was born in New York City. His father, George Shrady, was one of the physicians who attended former president Ulysses S. Grant during the struggle with throat cancer that led to his death on July 23, 1885. Shrady graduated from Columbia University in 1894 and spent one year thereafter at Columbia's law school. He left law school to join with his brother-in-law, Jay Gould (son of millionaire Edwin Gould, the financier), at the Continental Match Company. The company failed and Shrady contracted typhoid fever which diverted him forever from the business world. His recuperation left spare time to pursue a growing interest in art. Shrady's wife, Harrie Moore, submitted some of his paintings to an exhibition of the National Academy of Design without his knowledge and they sold quickly. He then began to teach himself sculpture using zoo animals and his pets as models. Shrady and architect William Casey Pearce won the competition to build the Ulysses S. Grant Memorial in 1902. In the twelve years Shrady spent executing the memorial, he studied biology at the American Museum of Natural History and dissected horses to gain a better understanding of animal anatomy.
