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.   Related Paintings of LEONARDO da Vinci :. | Madonna with the Yarnwinder | Raffaello Sanzio named Raffael Portrat of Lorenzo de Medici | Profile of an old man | Studies fur the adoration of the Konige | Portrait of Ginevra de Benci |

Born in Haarlem, he received instruction from his father Pieter Claesz, and from the painters Jan van Goyen, Pieter de Grebber, Jan Baptist Weenix, Jan Wils and Claes Cornelisz. Moeyaert.According to Houbraken, Carel de Moor told him that Berchem got his name from two words "Berg hem" for "Save him!", an expression used by his fellows in Van Goyen's workshop whenever his father chased him there with the intent to beat him. No trip or Grand Tour by Berchem was documented by Houbraken though he mentioned another story about the "Berg hem!" nickname which came from Berchem's conscription as a sailor; the man in charge of impressment knew him and sent him ashore with the words "Save him!".Today his name is assumed to come from his father's hometown of Berchem, Antwerp. According to the RKD he traveled to Italy with Jan Baptist Weenix, whom he called his cousin, in 1642-5. Works by him are signed both as "CBerghem" and "Berchem".

Sven Birger Sandzen
(5 February 1871-19 June 1954), known more commonly as Birger Sandzen, was a Swedish-American painter best known for his landscapes. He produced most of his work while working as an art professor at the Bethany College, Lindsborg, Kansas. Sandzen was born in Blidsberg, Ulricehamn Municipality, Västra Götaland County, Sweden, the son of a Lutheran minister and his wife, an accomplished watercolorist. A protege of Anders Zorn, Sandzen showed an interest in art at from early age, and at the age of 10 joined Cathedral School (Katedralskolan) situated in Skara, to study art under the tutelage of Olof Erlandsson, a graduate of the Royal Swedish Academy of Arts. After graduating in 1890, Sandzen studied for a short time at the University of Lund before moving to Stockholm. It was his intention to enroll at the Royal Swedish Academy of Arts. However, the waiting list proved too long for him. Instead, he sought out and joined a group of young artists who were studying under Anders Zorn, Richard Bergh and Per Hasselberg. This group would later be known as the Artists League (Konstnärsförbundet).At the end of his studies, Zorn and Bergh recommended that Sandzen complete his painting studies in Paris. In 1894, Sandzen left Stockholm to study under Edmond Aman-Jean who introduced Sandzen to pointillism.
