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.

active in Florence 1423-Venice 1470Cornelis Holsteyn
(1618 - 2 December 1658) was a Dutch Golden Age painter from Haarlem.
According to the RKD he was a painter of historical allegories, portraits, and interior decorations, trained by his father Pieter Holsteyn I. According to Houbraken, his father was a glass painter, and thus was trained for glass painting, but the market in glass painting not being what it was, he turned his hand to painting canvas. Houbraken felt he received less for a painting than he deserved, because his work was of a very high quality. He describes a Triumph of Bacchus, and a Lycurgus, which was painted for the Amsterdam Orphanage.
According to the RKD, he moved to Amsterdam with his brother Pieter Holsteyn II in 1647, became poorter there in 1652, and was betrothed there on Christmas eve, 1654. He was buried in the Nieuwe Kerk on December 2, 1658 from his home on the Rozengracht. Houbraken claimed he had been fit until his sudden death by Hartvang, or heart-attack.

Alexei Kondratyevich Savrasov (Russian) (May 24, 1830 - October 8, 1897) was a Russian landscape painter and creator of the lyrical landscape style.
Savrasov was born into the family of a merchant. He began to draw early and in 1838 he enrolled as a student of professor Rabus at the Moscow School of Painting, Sculpture and Architecture (graduated in 1850), and immediately began to specialize in landscape painting.

In 1857, Savrasov became a teacher at the Moscow School of painting, sculpturing and architecture. His best disciples, Isaac Levitan and Konstantin Korovin, remembered their teacher with admiration and gratitude.
