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 :. | Profile of an old man | The Virgin and Child with St Anne | Interior view of the Schadels | The Refectory with the Last Supper after restoration g | The Annunciation |

Anton Melbye
(1818-1875) was a Danish painter. He studied at the Royal Danish Academy of Fine Arts and was a private student of Christoffer Wilhelm Eckersberg. He achieved international success as a marine artist, travelling widely especially to Morocco and Turkey. His paintings are realistic, often enhanced with dramatic light and weather effects as in Eddystone Lighthouse (1846) which earned him the Thorvaldsen Medal. He was also influenced by Camille Corot whom he met in Paris where he lived from 1847 to 1858. While in Paris he met Napoleon III who ordered a large painting from him.
Charles Frederic Ulrich
Charles Frederic Ulrich (1858, New York City - 1908, Berlin), was an American painter. According to the RKD he worked in the Netherlands ca. 1890. He attended the Royal Academy in Munich, Germany, as did William Merritt Chase, who like him, was influenced by Dutch Golden Age painting and who has been documented as painting his portrait. He was discovered by Thomas B. Clarke, a lace and linen manufacturer in New York who became a collector of contemporary American art. Ulrich painted his portrait in gratitude after his painting "In the Land of Promise, Castle Garden" was shown at the National Academy of Design, where it won the National Academy's first Thomas B. Clarke Prize for Best American Figure Composition.
BEER, Jan de
Netherlandish Painter, ca.1475-1528 South Netherlandish painter and draughtsman. He is first mentioned in 1490 in the register of the Antwerp Guild of St Luke, apprenticed to the painter Gillis van Everen ( fl 1477-1513). In 1504 de Beer became a master. He subsequently served as alderman of the guild in 1509 and dean in 1515, although he found himself temperamentally unsuited to the position of dean, as is known from a lawsuit he filed in 1519 regarding guild administration. This document also reveals that de Beer participated in the preparations for Charles V's 'Joyous Entry' into Antwerp in 1515 and for the Antwerp Society of Rhetoricians' entry that year in the Malines landjuweel (regional competition of the rhetoricians). In 1510 and 1513 de Beer enrolled apprentices; his son Aert de Beer (c. 1509-before 6 Aug 1540) became an Antwerp master in 1529. The artist is undocumented between 1519 and 1528, by which date he was dead. In 1567 Guicciardini included de Beer in his list of famous Netherlandish painters.
