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 :. | John the Baptist | Portrait of Cecilia Gallarani | Detail of Madonna of the Rocks | The Last Supper-l | Madonna of the Rocks |

C.R. Leslie
English genre painter , 1794-1859 was an American artist best known for his cartoons and caricatures of actors and other celebrities. Though his work was heavily in demand through the 1920s and is often considered to epitomize the era, his personal life was troubled by mental illness, and he was nearly forgotten soon after his suicide, shortly before his fortieth birthday. English genre painter, was born in London on 19 October 1794. His parents were American, and when he was five years of age he returned with them to their native country. They settled in Philadelphia, where their son was educated and afterwards apprenticed to a bookseller. He was, however, mainly interested in painting and the drama, and when George Frederick Cooke visited the city he executed a portrait of the actor from recollection of him on the stage, which was considered a work of such promise that a fund was raised to enable the young artist to study in Europe. He left for London in 1811, bearing introductions which procured for him the friendship of West, Beechey, Allston, Coleridge and Washington Irving, and was admitted as a student of the Royal Academy, where he carried off two silver medals. At first, influenced by West and Fuseli, he essayed high art, and his earliest important subject depicted Saul and the Witch of Endor; but he soon discovered his true aptitude and became a painter of cabinet-pictures, dealing, not like those of David Wilkie, with the contemporary life that surrounded him, but with scenes from the great masters of fiction, from Shakespeare and Cervantes, Addison and Moliere, Swift, Sterne, Fielding and Smollett. Of individual paintings we may specify Sir Roger de Coverley going to Church (1819); May-day in the Time of Queen Elizabeth (1821); Sancho Panza and the Duchess (1824); Uncle Toby and the Widow Wadman (1831); La Malade Imaginaire, act iii. sc. 6 (1843); and the Dukes Chaplain Enraged leaving the Table, from Don Quixote (1849).
Vicente Lopez
1772-1850 Spanish Vicente Lopez Gallery was an Argentine writer and politician who acted as interim President of Argentina from July 7, 1827 to August 18, 1827. He also wrote the lyrics of the Argentine National Anthem adopted in May 11, 1813. Lopez began his primary studies in the San Francisco School, and later studied in the Real Colegio San Carlos, today the Colegio Nacional de Buenos Aires. He obtained a doctorate of laws in the University of Chuquisaca. He served as a captain in the Patriotic Regiment during the English invasions. After the Argentine victory he composed a poem entitled El triunfo argentino (The Argentine Triumph). He participated in the Cabildo Abierto of May 22, 1810 and supported the formation of the Primera Junta. He had good relations with Manuel Belgrano. When the royalist members of the city government of Buenos Aires were expulsed, he was elected mayor of the city; he was an enemy of the party of Cornelio Saavedra and one of the creators of the First Triumvirate, of which he was the Treasurer. Lopez was a member of the Constituent Assembly of year XIII, representing Buenos Aires. At the request of the Assembly, he wrote the lyrics to a "patriotic march", which eventually became the Argentine National Anthem. It was a military march, whose music was composed by the Catalan Blas Parera; it was approved on March 11, 1813. The first public reading was at a tertulia on May 7 in the house of Mariquita Sanchez de Thompson. It displaced a different march, written by Esteban de Luca, which would have been the hymn if not for the more militaristic Lopez.
