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 :. | Leda fh | Anatomical study of the brain and the scalp | Woman portrait | Lorenzo de Medici between Antonio Pucci and Francesco Sassetti, with Giulio de Medici, fresco by Ghirlandaio | Leonardo there Vinci and Andrea del Verrocchio, madonna with the child and angels |

Francis Nicholson
English Painter, 1753-1844 English painter. After studying with a local artist in Scarborough, Nicholson began his career in his native Pickering, producing sporting pictures and portraits for Yorkshire patrons. In the mid-1780s a sideline in portraits of country houses led him to concentrate on landscapes in watercolour. From 1789 he contributed views of Yorkshire and Scotland to exhibitions at the Royal Academy. He also supplied topographical views for the Copper Plate Magazine. Although his market increasingly became London-based, Nicholson continued to live in Yorkshire (at Whitby, Knaresborough and Ripon), only moving to London c. 1803.
Blanchet, Louis-Gabriel
French Painter, 1705-1772 French painter, active in Rome. He won second place in the Prix de Rome competition in 1727 and thereafter settled in Rome, where he enjoyed the patronage of Nicolas Vleughels, Director of the Acad?mie de France, and the Duc de Saint-Aignan (1684-1776), who at that time was French Ambassador to the Holy See. In 1752 Blanchet painted the Vision of Constantine (Paris, Louvre), a copy of Giulio Romano's fresco in the Sala di Costantino in the Vatican. He was, however, principally a portrait painter. His portrait of Tolozan de Montfort (1756; Lyon, Mus. B.-A.) is a fine example of his elegant, rather nervous style and his distinctive use of colour. In the same year Blanchet executed a portrait of the contemporary painter Johann Mandelberg (1730-86; Copenhagen, Kon. Dan. Kstakad.). Other surviving works of his include St Paul (signed and dated 1757; Avignon, Mus. Calvet) and his full-length portrait of P. P. Lesueur and E. Jacquier (1772; Nantes, Mus. B.-A.).
Frederic Yates
Frederic Yates (1854-1919) was an English painter. He gave up a business career to study painting in the Paris ateliers of Leon Bonnat, Gustave Boulanger, and Jules Joseph Lefebvre. In 1886, he moved to San Francisco where his family had settled a few years earlier. In San Francisco, he became a popular portraitist and taught at the newly formed Art Students League of San Francisco. On one of his visits to Europe, he made the acquaintance of the Dowager Marchioness of Downshire who became his patron and introduced him to London society. Yates was active in San Francisco until 1900, when he returned to England, where he lived at "Cote How" near Grasmere until 1906. During this period he painted the former United States president Woodrow Wilson and John Haden Badley. He died in 1919.
