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.

(31 March 1843 - 22 June 1917) was a Danish painter. He was a part of the Danish artistic generation in the late 19th century, along with Peder Severin Krøyer and Theodor Esbern Philipsen, who broke away from both the strictures of traditional Academicism and the heritage of the Golden Age of Danish Painting, in favor of naturalism and realism.
He was known especially for his history paintings, and especially those depicting strong, tragic, legendary women in Danish history. He also produced works of many other genres including landscapes, street scenes, folk scenes and portraits.
He had a far-reaching effect on the development of Danish art through his effective support of individual style among his students during the many years he taught, and by his pioneering use of color.

Mexican painter, b. Coyoacen. As a result of an accident at age 15, Kahlo turned her attention from a medical career to painting. Drawing on her personal experiences, her works are often shocking in their stark portrayal of pain and the harsh lives of women. Fifty-five of her 143 paintings are self-portraits incorporating a personal symbolism complete with graphic anatomical references. She was also influenced by indigenous Mexican culture, aspects of which she portrayed in bright colors, with a mixture of realism and symbolism. Her paintings attracted the attention of the artist Diego Rivera, whom she later married. Although Kahlo's work is sometimes classified as surrealist and she did exhibit several times with European surrealists, she herself disputed the label. Her preoccupation with female themes and the figurative candor with which she expressed them made her something of a feminist cult figure in the last decades of the 20th cent.
