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 Battle of Anghiari | The Last Supper-l | The Annunciation d | Study of a child | Adoration of the Magi |

Max Koch
(born July 17, 1854 - April 1, 1925) was a German-born Australian botanical collector. Born in Berlin, Koch was apprenticed to a merchant's office, but, not liking the work, joined the crew of a Glasgow-based sailing ship at Bremerhaven. He left it at Port Augusta, South Australia in April 1878, taking work at a wheat farm. Later he moved to Mount Lyndhurst sheep station, where he remained for many years. Around 1896 he began serious botanical collecting. Koch visited Germany around 1902-1903, then returned to Australia, and in 1904 moved to the extreme south-west of Western Australia, where he spent the next 17 years working in the timber industry. By that time he had a large family, and he supplemented his income by plant specimens, and, in his later years, seed. He died at Pemberton, Western Australia in 1925
Carl Haag
1820 - 1915 German painter, active in Britain. After studying in Nuremberg, he painted miniature portraits in Munich and Brussels. In 1847 he went to London to study English techniques of watercolour painting and evolved a method that he claimed achieved the 'brilliancy of oil painting, combined with the tender-sweetness of water-colours' . From 1850 he exhibited at the Society of Painters in Water-Colours and was elected a full member in 1853.
Gaspar Van Wittel
Dutch Baroque Era Painter, ca.1653-1736 was a Dutch landscape painter. Van Wittel learned painting in his hometown of Amersfoort. His first extant works were made in Hoorn in 1672, but he relocated to Rome with his family ca. 1675 and made his career there. In Amersfoort, he likely was exposed to Dutch landscape artists such as Jan van der Heyden and Gerrit Berckheyde. He married in Rome in 1697, and stayed most of his life in that city, though, between 1694 and 1710, he toured Italy and painted in places like Florence, Bologna, Ferrara, Venice, Milan, Piacenza and Naples. He is one of the principal painters of topographical views known as vedute. His son Luigi would become a famous architect and also carries the italianized family name of Vanvitelli. In Luigi's biography is written that his father was born in July 1656,
