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-o | Flower Studies | Portrait of Ginerva de'Benci-u | The Battle of Anghiari | Virgin and Child with St Anne |

Henri Matisse
French Fauvist Painter and Sculptor, 1869-1954 Henri Matisse is considered the most important French artist of the 20th century and, along with Pablo Picasso, one of the most influential modernist painters of the last century. Matisse began studying drawing and painting in the 1890s. A student of the masters of Post-Impressionism, Matisse later made a reputation for himself as the leader of a group of painters known as Les Fauves. An ironic label given to them by a critic, the name reflected Matisse's aggressive strokes and bold use of primary colors. In 1905 Matisse gained sudden fame with three paintings, including Woman with the Hat, purchased by the wealthy American ex-patriot Gertrude Stein. Beyond painting, he worked with lithographs and sculpture, and during World War II he did a series of book designs. Later in his career he experimented with paper cutouts and designed decorations for the Dominican chapel in Vence, France. Along with Picasso,
Walter Griffin
1861-1935 Walter Burley Griffin November 24, 1876?CFebruary 11, 1937) was a US architect and landscape architect, who is best known for his role in designing Canberra, Australia's capital city. He has also been credited with the development of the L-shaped floor plan, the carport and the first use of reinforced concrete. Influenced by the Chicago-based Prairie School, Griffin went on to develop a unique modern style. For much of his career Griffin worked in partnership with his wife Marion Mahony Griffin. In the 28 years of their architectural partnership, the Griffins designed over 350 building, landscape and urban-design projects as well as designing construction materials, interiors, furniture and other household items.
