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 last dinner | Madonna with the Yarnwinder after 1510 | The annunciation | Muscle structure of the thigh | Hi Hieronymus |

Eugene Grasset
Swiss-born French Art Nouveau Designer, 1845-1917 Born Eugene Samuel Grasset in Lausanne, Switzerland, his birth year is sometimes stated as 1841. He was raised in an artistic environment as the son of a cabinet designer maker and sculptor. He studied drawing under Francois-Louis David Bocion (1828-1890) and in 1861 went to Zurich to study architecture. After completing his education, he visited Egypt, an experience that would later be reflected in a number of his poster designs. He became an admirer of Japanese art which too influenced some of his creative designs. Between 1869 and 1870, Grasset worked as a painter and sculptor in Lausanne but moved to Paris in 1871 where he designed furniture fabrics and tapestries as well as ceramics and jewelry. His fine art decorative pieces were crafted from ivory, gold and other precious materials in unique combinations and his creations are considered a cornerstone of Art Nouveau motifs and patterns. Grasset poster for Mark Twain Joan of ArcIn 1877 Eugene Grasset turned to graphic design, producing income-generating products such as postcards and eventually postage stamps for both France and Switzerland. However, it was poster art that quickly became his forte. Some of his works became part of the Maitres de l Affiche including his lithograph, Jeanne d Arc Sarah Bernhardt. In 1890, he designed the Semeuse logo used by the dictionary publishers, Editions Larousse. With the growing popularity of French posters in the United States, Grasset was soon contacted by several American companies. In the 1880s, he did his first American commission and more success led to his cover design for the 1892 Christmas issue of Harper Magazine. In 1894 Grasset created The Wooly Horse and The Sun of Austerlitz for The Century Magazine to help advertise their serialized story on the life of Napoleon Bonaparte. The Wooly Horse image proved so popular that Louis Comfort Tiffany recreated it in stained glass. Grasset work for U.S. institutions helped pave the way for Art Nouveau to dominate American art. At the end of the 19th century, Grasset was hired to teach design at Ecole Guerin and Ecole Estienne in Paris. Among his students were Maurice Pillard Verneuil, Augusto Giacometti, Paul Berthon and Otto Ernst Schmidt. At the Universal Exhibition of 1900 in Paris, the G. Peignot et Fils typefoundry, introduced the Grasset typeface, an Italic design Eugene Grasset created in 1898 for use on some of his posters.
