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 :. | The Annunciation | Virgin of the Rocks | Pod of cherry and forest strawberry | Saint John the Baptist | The Last Supper |

Carl Ludwig Brandt
(22 September 1831 Holstein, Germany - 1905) was a German-born artist who worked mostly in the United States. Brandt was born near Hamburg, in Holstein, Germany. His father and grandfather were physicians in Hamburg. His father taught him drawing at the age of seven, and he subsequently studied in the principal galleries of Europe. He served in the First War of Schleswig (1848-1850), between Germany and Denmark. He came to the United States in 1852. He painted several portraits previous to 1864, and in that year built his studio in Hastings-on-Hudson, New York, but lived in Europe from 1865 until 1869. He was chosen a national academician in 1872, and in 1883 was elected first director of the Telfair Academy of Arts and Sciences, Savannah, Georgia, where he resided in winter. At Telfair he offered art instruction and oversaw art acquisitions, including plaster casts, thus transforming a family mansion into a cultural institution.
Johannes Hubertus Leonardus de Haas
(25 March 1832 - 4 August 1908) was a Dutch animal and landscape painter, and a peripheral figure of the Hague School. Born at Hedel, De Haas spend his youth in Amsterdam where he got his first art education at evening-classes at the Koninklijke Academie. Consequently he moved to Haarlem where he was apprenticed to the artist Pieter Frederik van Os. During his stay in Haarlem he befriended Paul Gabriël and Hendrik Dirk Kruseman Van Elten who were also studying with Van Os. In 1853, together with his two friends, De Haas decided to go to Oosterbeek. Here they came into contact with the influential landscape painter Johannes Warnardus Bilders and the group of painters which had gathered around him, many of whom would later be part of the Hague School. De Haas also met his future wife in Oosterbeek, Bilders' daughter, Caroline. In 1855 he received good reviews for his pictures that were exhibited in Paris from the noted art critic Jean Baptiste Gustave Planche. In 1857 De Haas first went to Brussels, where he became friends with Willem Roelofs. De Haas frequently returned to the Netherlands and Oosterbeek for inspiration and Caroline. From 1860 his friend Gabriël also lived in Brussels, and De Haas often painted cattle in the landscapes of both Roelofs and Gabriel, fitting in perfectly with both their styles. In 1860 he won the gold medal at the exhibition of Utrecht. From 1861 until 1869 De Haas is permanently settled in Brussels, painting mainly on the coasts of Flanders and Picardie in northern France. He married Caroline Bilders in 1862, and in 1864 they are briefly joined by her brother, the promising painter Gerard Bilders. In 1865 Caroline dies at the age of 24 of tuberculosis, leaving him with a young son. During his stay in Brussels De Haas is instrumental in passing on the style of the Barbizon school to the painters at Oosterbeek.
