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 :. | The Annunciation | virgin and child with st.anne | Last Supper | St John in the Wilderness | The Verkundigung |

Isaac Grunewald
Swedish, 1889-1946,was a Swedish-Jewish Expressionist painter born in Stockholm. Having studied at a Swedish art school, at age nineteen Gr??newald travelled to Paris to study under Henri Matisse. In 1909 he gained recognition in his homeland when he exhibited his work at Halldins konsthandel. He met Fauvist painter Sigrid Hjert??n, who had studied at the College of Crafts and Design in Stockholm, and encouraged her to return with him to study in Paris. Married in 1911, they became part of a group of Scandinavian artists known as "De Unga" (The Young Ones). The Crane (1915) by Isaac GrunewaldGrenewald and Hjerten regularly exhibited together at home and abroad and art historians now often cite them as being responsible for introducing modernism to Sweden. At a time in history when anti-Semitism was widespread and women in art were frowned upon, although widely known they were never fully accepted by the artistic community of the day and their works were often the subject of ridicule. Partly as a result of this, Isaac Grunewald had to supplement his income creating stage designs for the Royal Dramatic Theatre and the Royal Swedish Opera. He decorated the walls and ceiling of an auditorium (since renamed Grunewald Hall) at the Stockholm Concert Hall, site of the Nobel Prize ceremony, and the walls of the Matchstick Palace. The author of numerous essays on art, with his 1918 exhibit at Stockholm's Liljevalchs Konsthall Isaac Grunewald published his manifesto on Expressionism and opened his own art school. During the Second World War Grunewald worked at the renowned Rorstrand porcelain factory. His wife Sigrid Hjerten suffered from lifelong mental health problems frequently evidenced by anxiety and paranoia that resulted in her being hospitalized for extended periods in the 1930s. During the marriage the couple were frequently apart from each other for long periods and they separated permanently in 1937 and soon divorced. Isaac Grunewald remarried and in 1946 both he and his second wife were killed in an airplane crash. He is buried in Stockholm's Norra begravningsplatsen ("Northern Cemetery"). His 1912 self-portrait and his 1915 painting "The Singing Tree" appeared on Swedish postage stamps. Today, institutions such as the Arken Museum of Modern Art in Ishoj, Denmark rank Grunewald and Hjerten among the 20th Century's most important Scandinavian artists.
