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 :. | The adoration of the Konige | Lorenzo de Medici between Antonio Pucci and Francesco Sassetti, with Giulio de Medici, fresco by Ghirlandaio | Female head (La Scapigliata) wt | Portrat of a Madchens | Profile of an old man |

Aert van der Neer
1603-1677 Dutch Although generally known by the name of Aert, he usually signed himself Aernout. According to Houbraken, van der Neer spent his youth in Arkel near Gorinchem (Gorkum), a town on the river Waal, east of Dordrecht, where he worked as a majoor (steward) for the lords of Arkel. He became an amateur painter, possibly as a result of his contact with the Camphuyzen brothers Rafael Govertsz. (1597/8-1657) and Jochem Govertsz. (1601/2-59). Aert married Lysbeth Govertsdr (Liedtke) who was almost certainly Rafael and Jochem sister. Rafael acted as witness at the baptism of their daughter Cornelia in 1642. Around 1632 van der Neer and his wife moved to Amsterdam where, in about 1634, their eldest son, Eglon, was born.
Pieter van Aelst
(August 14, 1502 - December 6, 1550) was a Flemish painter. He studied under Bernaert van Orley and later lived in Italy before entering the Antwerp Guild of painters in 1527. In 1533, he travelled to Constantinople for one year in a failed attempt to establish business connections for his tapestry works. Van Aelst established a studio in Brussels in 1544, where he created paintings and tapestries. His students include Gillis van Coninxloo, Willem Key, Hans Vredeman de Vries, Michiel Coxcie, and possibly Pieter Brueghel the Elder, who did eventually marry van Aelst's daughter, Mayken. His second wife, Mayken Verhulst, was an artist as well, and, according to Carel van Mander, the first teacher of her grandchildren, Pieter Brueghel the Younger and Jan Brueghel the Elder. He was also the uncle of Joachim Bueckelaer. Van Aelst's studio is also well known for its engraved works. In particular, van Aelst is noted for his 1539 translation of Sebastiano Serlio's architectural treatise, Architettura, which is credited with having played a crucial role in spreading Renaissance ideas to the Low Countries and hastening the transition from the late Gothic style prevalent in the area at the time. He was in charge of the spectacular decorations for the 1549 Royal entry into Antwerp of Philip II of Spain, "the most famous entry of the century", according to Roy Strong.
Henri Rousseau
French 1844-1910 Henri Rousseau Locations He was born in Laval in the Loire Valley into the family of a plumber. He attended Laval High School as a day student and then as a boarder, after his father became a debtor and his parents had to leave the town upon the seizure of their house. He was mediocre in some subjects at the high school but won prizes for drawing and music. He worked for a lawyer and studied law, but "attempted a small perjury and sought refuge in the army," serving for four years, starting in 1863. With his father's death, Rousseau moved to Paris in 1868 to support his widowed mother as a government employee. In 1871, he was promoted to the toll collector's office in Paris as a tax collector. He started painting seriously in his early forties, and by age 49 he retired from his job to work on his art. His wife died in 1888 and he later remarried. Rousseau claimed he had "no teacher other than nature", although he admitted he had received "some advice" from two established Academic painters, Felix Auguste-Clement and Jean-Leon Gerome. Essentially he was self-taught and is considered to be a naive or primitive painter.
