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 Annunciation | Madonna with a Flower | Detail of Madonna of the Rocks | Lady with Emine | Madonna Benois Madonna with a Flower |

Henri-Lucien Doucet
(1856-1895) was a French figure and portrait painter, born in Paris, where he studied under Lefebvre and Boulanger, and in 1880 won the Prix de Rome. His pictures are usually piquant, sparkling representations of modern life, eminently Parisian in style, but the audacious realism of his earlier work is not maintained in his later, which is somewhat characterless. His portraits in pastel are also notable. His most widely known picture is Apres le bal (After the Ball, 1889). Other excellent examples are the portraits of Celestine Galli-Marie as Carmen (1884, Marseille Museum), La princesse Mathilde Laetitia Wilhelmine Bonaparte and My Parents (1890, Lyons Museum), A Spanish Woman (Pontoise Museum), and Nude Figure (1890). He was awarded a first-class medal for pastel in 1889 and the Legion of Honour in 1891. His painting A Skating Party, of 1893, was exhibited at the Chicago World Fair or the World's Columbian Exposition, which was held from May to October 1893 in Chicago in honour of the 400th anniversary of Columbus' discovery of the New World. Goupil made a limited edition first impression photogravure of the painting.

Abraham Hendriksz van Beijeren (ca. 1620 The Hague - March 1690 Rotterdam) was a Dutch Baroque era painter. He was little regarded in his day but is now considered one of the greatest of still-life painters. Van Beijeren (alternatively spelled "Beyeren") lived in a succession of Dutch towns. Born in The Hague, the artist also lived in Delft, Amsterdam, Alkmaar and Gouda. In 1678 he settled in Rotterdam, where he died in 1690.
