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 :. | Last Supper (mk08) | The muscles of Thorax and shoulders in a lebnden person | Study fur the Sforza-Reiterstandbild | Abendmahl | Ceiling decoration yy |

Moritz Daniel Oppenheim
(January 7, 1800, Hanau, Germany - February 26, 1882, Frankfurt am Main) was a German painter who is often regarded as the first Jewish painter of the modern era. His work was informed by his cultural and religious roots at a time when many of his German Jewish contemporaries chose to convert. Oppenheim is considered by the scholar Ismar Schorsch to be in sympathy with the ideals of the Wissenschaft des Judentums movement, because he remained "fair to the present" without denying his past. Oppenheim was born to Orthodox Jewish parents at Hanau, Germany in 1800; he died at Frankfurt am Main in 1882. His niece was the wife of student and fellow painter Benjamin Prins, Rosa Benari. He received his first lessons in painting from Westermayer, in Hanau, and entered the Munich Academy of Arts at the age of seventeen. Later he visited Paris, where Jean-Baptiste Regnault became his teacher, and then went to Rome, where he studied with Bertel Thorwaldsen, Barthold Georg Niebuhr, and Friedrich Overbeck. There he studied the life of the Jewish ghetto and made sketches of the various phases of its domestic and religious life, in preparation for several large canvases which he painted upon his return to Germany. In 1825 he settled at Frankfurt, and shortly after exhibited his painting David Playing Before Saul, to see which a great number of admirers from all parts of Europe visited his studio. In 1832, at the instance of Goethe, Charles Frederick, Grand Duke of Saxe-Weimar-Eisenach conferred upon him the honorary title of professor.
