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 :. | Studies for a Nativity | Detail of Madonna of the Rocks | Portrait of Ginevra de' Benci | Regisol | The Battle of Anghiari |

Henry Merwin Shrady
American Sculptor, 1871-1922,was the sculptor of the Ulysses S. Grant Memorial in Washington, D.C. Shrady was born in New York City. His father, George Shrady, was one of the physicians who attended former president Ulysses S. Grant during the struggle with throat cancer that led to his death on July 23, 1885. Shrady graduated from Columbia University in 1894 and spent one year thereafter at Columbia's law school. He left law school to join with his brother-in-law, Jay Gould (son of millionaire Edwin Gould, the financier), at the Continental Match Company. The company failed and Shrady contracted typhoid fever which diverted him forever from the business world. His recuperation left spare time to pursue a growing interest in art. Shrady's wife, Harrie Moore, submitted some of his paintings to an exhibition of the National Academy of Design without his knowledge and they sold quickly. He then began to teach himself sculpture using zoo animals and his pets as models. Shrady and architect William Casey Pearce won the competition to build the Ulysses S. Grant Memorial in 1902. In the twelve years Shrady spent executing the memorial, he studied biology at the American Museum of Natural History and dissected horses to gain a better understanding of animal anatomy.
Conrad Martens
England/Australia Painter , 1801-1878 Australian painter, lithographer and librarian of English birth. Son of a London merchant, he studied c. 1816 under Copley Fielding. His training was as a watercolourist and his most important works are watercolours, although he also produced paintings in oils. His early work displays the taste then current for the Picturesque. Francis Danby, David Cox and Turner were artists he admired. Martens left for India in 1832 or 1833 but at Montevideo joined Charles Darwin's expedition, replacing Augustus Earle as topographical draughtsman aboard the Beagle. The work strengthened his observation of detail and skill as a draughtsman. He left the expedition in October 1834 and, travelling via Tahiti and New Zealand, arrived in Sydney in April 1835. There he worked as a professional artist, in the 1840s and 1850s producing lithographic views of the Sydney area to augment his income. In 1863 he was appointed Parliamentary Librarian, which secured his finances. The skills he had acquired aboard the Beagle helped to gain him commissions to depict the estates around Sydney. However, his admiration for Turner, and with this the desire to elevate landscape as a subject, prompted him to subordinate line to mood in a Romantic treatment of the landscape. His thoughts were clearly stated in a lecture on landscape painting given in 1856 at the Australian Library, Sydney (see Smith, 1975).
