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 :. | Virgin of the Rocks | The Fotus in the Uterus | Madonna with the Yarnwinder | Interior view of the Schadels | Head and shoulders Christs |

Adolph Friedrich Vollmer
(17 December 1806 - 12 February 1875) was a German landscape and marine painter and graphic artist. He and his contemporary, the painter Christian Morgenstern, were pioneers in Hamburg of early Realism in painting. As son of a bookkeeper to a Hamburg merchant, Vollmer grew up in humble circumstances.[3] Determined to become a painter against the wishes of his father,[4] he became an apprentice to the brothers Suhr who owned a graphic workshop producing panorama prints. For one and a half years Vollmer travelled throughout Germany with one of the brothers, Cornelius Suhr, as had been Morgenstern before him. In 1826 he was introduced by the Hamburg art-dealer Ernst Harzen to the wealthy aristocrat and supporter of the arts, Carl Friedrich von Rumohr, who was patron to many young Hamburg artists among them Morgenstern and Otto Speckter. Probably on Rumohr advice Vollmer completed his studies under Christoffer Wilhelm Eckersberg at the Royal Danish Academy of Fine Arts in Copenhagen. He then moved to Munich from where he undertook journeys to Lake Konstanz, to the Austrian and Swiss Alps, to Venice, to Le Havre and to the Netherlands. In 1839 Vollmer returned to Hamburg and settled there. One of his sons, Johannes Vollmer, became a prominent architect of protestant churches; a grand-son was the art historian and encyclopaedist Hans Vollmer who, for many years, edited the Thieme-Becker Kenstler Lexikon. Vollmer became blind in 1866.
