LEONARDO da Vinci
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.

(1571, Utrecht - 6 March 1638, Utrecht) was a Dutch painter, mainly of portraits.
Moreelse was a pupil of the Delft portrait painter Michiel Jansz. van Mierevelt, who had himself been a pupil of Anthonie van Blocklandt. He took a study-trip to Italy, where he received many portrait commissions. Back in Utrecht, in 1596 he became a member of the zadelaarsgilde, which was the traditional name in Utrecht for the Guild of Saint Luke. In 1611, along with Abraham Bloemaert, he was one of the founders of a new painters' guild, called "St. Lucas-gilde", and became its first deken.
Moreelse was a well known portrait painter who received commissions from right across the Dutch Republic. His earliest work dates to 1606. Other than portraits, he also painted a few history paintings in the Mannerist style and in the 1620s produced pastoral scenes of herders and shepherds. He belonged to the same generation as Abraham Bloemaert and Joachim Wtewael, and like Wtewael he played an important role in the public life of their city. His version of Diana and Callisto was engraved by Jan Saenredam. In 1618, when the anti-remonstrants came to power in Utrecht, he was raadslid.
French painter and writer. He was the son of a cloth merchant. Relations with his parents were never harmonious, and in 1884, against his father's wishes, he enrolled as a student at the Atelier Cormon in Paris. There he became a close friend of Louis Anquetin and Toulouse-Lautrec. In suburban views of Asni?res, where his parents lived, Bernard experimented with Impressionist and then Pointillist colour theory, in direct opposition to his master's academic teaching; an argument with Fernand Cormon led to his expulsion from the studio in 1886. He made a walking tour of Normandy and Brittany that year, drawn to Gothic architecture and the simplicity of the carved Breton calvaries. In Concarneau he struck up a friendship with Claude-Emile Schuffenecker and met Gauguin briefly in Pont-Aven. Jakob Issaks Swanenburgh
