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.

1872-1942,German painter, printmaker and architect. He studied from 1890 to 1893 in D?sseldorf. In 1895 he bought the Barkenhoff in Worpswede, near Bremen. Soon afterwards, with colleagues from the WORPSWEDE COLONY, including Fritz Mackensen, Fritz Overbeck (1869-1909), Hans am Ende (1864-1918) and Otto Modersohn (1865-1943), he exhibited successfully at the Glaspalast in Munich. He provided illustrations for the periodical Die Insel, and undertook the interior decoration of the G?ldenkammer in Bremen. In 1906 he visited Ceylon (now Sri Lanka) for convalescence and in 1909 he went to England to study the principles of the garden city movement. He served in the German army in World War I, his writing of a pacifist letter to the Emperor in January 1918 prompting an official inquiry into his state of mental health. In 1919 he founded the Arbeitsgemeinschaft Barkenhoff in Worpswede, in an unsuccessful attempt to create an Arbeitsschule and a utopian community. Ralph Earl

Ralph Earl was born in either Shrewsbury or Leicester, Massachusetts. By 1774, he was working in New Haven, Connecticut as a portrait painter. In the autumn of 1774, Earl returned to Leicester, Massachusetts to marry his cousin, Sarah Gates. A few months later, their daughter was born; however, Earl left them both with Sarah's parents and returned to New Haven.
Like so many of the colonial craftsmen, Earl was self-taught, and for many years was an itinerant painter. In 1775, Earl visited Lexington and Concord, which were the sites of recent battles in the American Revolution. Together with engraver Amos Doolittle, he painted four of his most famous pictures, all battle scenes.
Although his father was a colonel in the Revolutionary army, Ralph Earl himself was a Loyalist. In 1778, he left behind his wife and daughter and escaped to England by disguising himself as the servant of British army captain John Money.Sergei Svetoslavsky
