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 :. | Bacchus | The Virgin and Child with Anne (mk05) | Detail of Madonna of the Rocks | Adoration of the Magi | Virgin of the Rocks |

George Hayter
1792 - 1871 English painter and printmaker. He was the son of Charles Hayter (1761-1835), miniature painter, author of manuals for art instruction and Professor of Perspective and Drawing to Princess Charlotte. In 1808 George entered the Royal Academy Schools, and in 1815 was appointed Painter of Miniatures and Portraits by Princess Charlotte. Hayter was awarded the British Institution's premium for history painting for the Prophet Ezra (1815; Downton Castle, Heref. & Worcs), purchased by Richard Payne Knight. Encouraged by his patron, John Russell, 6th Duke of Bedford, he travelled to Italy to study in 1816, gaining election as an honorary member of the Accademia di S Luca in Florence. Returning to London in 1818, Hayter practised as a portrait painter in oils and history painter and occasionally acted as an art dealer. Dubbed 'The Phoenix' by William Beckford, Hayter showed a pomposity that irritated his fellow artists, but he mixed freely with many aristocratic families.
edward hopper
American painter, printmaker and illustrator. He was brought up in a town on the Hudson River, where he developed an enduring love of nautical life. When he graduated from Nyack Union High School in 1899, his parents, although supportive of his artistic aspirations, implored him to study commercial illustration rather than pursue an economically uncertain career in fine art. He studied with the Correspondence School of Illustrating in New York City (1899-1900). He continued to study illustration at the New York School of Art (1900-1906), under Arthur Keller (1866-1925) and Frank Vincent Du Mond (1865-1951), but began to study painting and drawing after a year. Hopper began in the portrait and still-life classes of William Merrit Chase, to whose teaching he later referred only infrequently and disparagingly. He preferred the classes he took with Kenneth Hayes Miller and especially those of Robert Henri. Hopper s skill won his fellow students respect, as well as honours in the school where, by 1905, he was teaching Saturday classes.
