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 fur the Sforza-Reiterstandbild | Interior view of the Schadels | Annunciation (detail) dg | Master of the Pala Sforzesca, profile of an old man | The annunciation |

David Dalhoff Neal
(October 20, 1838 - May 2, 1915), was an American artist. David Dalhoff Neal was born to father Stephen Bryant Neal and mother Mary (Dalhoff) Neal, on Middlesex Street, in Lowell, Massachusetts. His grandparents were Stephen Neal, and David Dalhoff and Sally (Bean) Dalhoff of Canterbury, New Hampshire, Dolhoffs that emigrated from Russia in 1763, for whom he was named. His mother's family, the Beans, migrated from Holland in the early 1830s. His aunt Elizabeth Dolhoff was very artistic, and his uncle Jesse Dolhoff was a great singer. He attended Lowell grammar schools, and high school at Lawrence, Massachusetts. Deciding to devote himself to the study of art, he then attended art classes at the recently opened Andover Academy in Andover, New Hampshire. When Neal was 14, his father died and his fortunes were "impaired", so he set sail for New Orleans. Here at the age of 15, he worked the docks as a wharf clerk with a wood shipping firm dealing in Brazilian and Honduran mahogany.
Henri Lucien Doucet
France 1856-1895 was a French figure and portrait painter, born in Paris, where he studied under Lefebvre and Boulanger, and in 1880 won the Prix de Rome. His pictures are usually piquant, sparkling representations of modern life, eminently Parisian in style, but the audacious realism of his earlier work is not maintained in his later, which is somewhat characterless. His portraits in pastel are also notable. His most widely known picture is Apres le bal (After the ball, 1889). Other excellent examples are the portraits of Madame Galli-Marie as Carmen (1884, Marseille Museum); the Princesse Mathilde and My Parents (1890, Lyons Museum); A Spanish Woman (Pontoise Museum); and a Nude Figure (1890). He was awarded a first-class medal for pastel in 1889 and the decoration of the Legion of Honor in 1891.
