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 :. | Reverse side of the portrait of Ginevra de' Benci | John the Baptist | Adoration of the Magi | The Baptism of Christ | The Battle of Anghiari |

French, 1736 - 1793 French engraver and publisher. He came from a family of artisans and owed his training in engraving to his brother-in-law, the engraver Louis Legrand (1723-1808). Through Legrand, Bonnet became the pupil of Jean-Charles Francois in 1756, a year before the latter discovered the CRAYON MANNER technique of engraving, designed to reproduce the effect of a coloured-chalk drawing. Around the end of 1757 Bonnet used the new technique to engrave a Cupid after Francois Eisen. Gilles Demarteau, a rival of Jean-Charles Francois
Carl Spitzweg
German Painter, 1808-1885 German painter. He trained (1825-8), at his father's insistence, as a pharmacist, by 1829 becoming manager of a pharmacy in the Straubing district of Munich. From 1830 to 1832 he made advanced studies in pharmacy, botany and chemistry at the University of Munich, passing his final examination with distinction. On receiving a large legacy in 1833, which made him financially independent, he decided to become a painter. He had drawn since the age of 15 and had frequented artistic circles since the late 1820s; but he had no professional training as a painter. He learnt much from contacts with young Munich landscape painters such as Eduard Schleich the elder and produced his first oil paintings in 1834. In 1835 he became a member of the Munich Kunstverein but left two years later due to disappointment over the reception of the first version of the Poor Poet (1837; Munich, Neue Pin.; second version 1839; Berlin, Neue N.G.), a scene of gently humorous pathos that has since become his most celebrated work. Spitzweg's decision to leave the Kunstverein, however, was also encouraged by his first successful attempts to sell his paintings independently. In 1839 he travelled to Dalmatia, where he made sketches that he used for many later works on Turkish themes (e.g. the Turkish Coffee House, c. 1860; Munich, Schack-Gal.). From the 1840s he travelled regularly, usually with his close friend, the painter Schleich, both within Bavaria and to Austria and Switzerland and also to the Adriatic coast, especially to Trieste.
