Leonardo Da Vinci
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.

(Paris, c. 1715 - Amsterdam, 19 November 1783) was a French painter who specialized in portraits executed in pastels.
Perronneau began his career as an engraver, apparently studying with Laurent Cars, whose portrait he drew, and working for the entrepreneurial printseller Gabriel Huquier, rue Saint-Jacques, Paris, making his first portraits in oils, and especially in pastels, in the 1740s. His career was much in the shadow of the master of the French pastel portrait, Maurice Quentin de La Tour. In the Salon of 1750, Perronneau exhibited his pastel portrait of Maurice-Quentin de la Tour, but found to his dismay that La Tour was exhibiting his own self portrait, perhaps a malicious confrontation to demonstrate his superiority in the technique.
He made his Salon debut with a pastel portrait in 1746 and received full membership in the Academie Royale de Peinture et de Sculpture in 1753, with portraits of fellow artist Jean-Baptiste Oudry and the sculptor Lambert-Sigisbert Adam, both now at the Louvre Museum. After 1779 he no longer exhibited in the Paris Salons, but the clientele in his portraits reveal how widely he travelled in the provinces of France, with a group of sitters connected with Orleans, but also in Toulouse, Bordeaux, Lyon. Farther afield he may have been in Turin and Rome, and in Spain, Hamburg, Poland, Russia and England.
He died in Amsterdam virtually unknown, according to his biographers.hertigen av orleansraoul dufy
raoul dufy(1877 to 1953) French painter, printmaker and decorative artist. From the age of 14 he was employed as a book-keeper, but at the same time he developed his innate gift for drawing at evening classes at the Ecole des Beaux-Arts in Le Havre,given by the Neo-classical painter Charles Lhuillier (1824-98). He discovered the work of Eug?ne Boudin, Poussin and Delacroix, whose Justice of Trajan (1840; Rouen, Mus. B.-A.) was 'a revelation and certainly one of the most violent impressions' of his life (Lassaigne, Eng. trans., p. 16). In 1900, with a grant from Le Havre, he joined his friend Othon Friesz in Paris and enrolled at the Ecole Nationale Sup-rieure des Beaux-Arts in the studio of L?on Bonnat. At the Mus?e du Louvre he studied the art of Claude Lorrain, to whom he painted several Homages between 1927 and 1947 (e.g. 1927; Nice, Mus. Mass-na). His encounter with works by van Gogh at the Galerie Bernheim-Jeune and with Impressionism at Durand-Ruel is reflected in such early works as Beach at St Adresse (1904; Paris, Pompidou).
