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 :. | Madonna in the rock grottos | Mona Lisa | Studies fur the adoration of the Konige | Virgin of the Rocks | Unfinished painting of St. Jerome in the Wilderness |

Anna Atkins
Tonbridge 1799-1871 Tonbridge,English botanist and pioneer of the photogram and photographic publishing. Daughter of the prominent scientist John George Children, Atkins was encouraged by him in her scientific interests. She was a competent watercolourist and published at least one lithograph. By 1823 her draughtsmanship and observational skills were refined enough for her to produce 200 illustrations for her father's translation of Lamarck's Genera of Shells. Botany was her particular love, especially the collection and study of seaweeds. Her father chaired the February 1839 Royal Society meeting at which Henry Talbot first revealed the manipulatory secrets of photogenic drawing. Father and daughter soon got a camera and took up the new art of photography, but Atkins's biggest contribution to it involved neither a camera nor her father. She conceived the idea of publishing a photographic record of her algae, making photograms by contact printing the dried specimens on sheets of sensitized paper.
Jean-Baptiste Santerre
French Baroque Era Painter, 1651-1717 The 12th child of a merchant, he was apprenticed to the portrait painter Jean Lemaire before entering the busy studio of the history painter Bon Boullogne. Although he executed some history paintings, he began to specialize in portraiture early in his career. The Portrait of Two Actresses (1699; St Petersburg, Hermitage), clearly influenced by Fran?ois de Troy, shows Santerre's interest in the well-known portrait painters of his time. Nevertheless, he was among the first painters in France to absorb the influence of Rembrandt, as in Young Girl at a Window (Orl?ans, Mus. B.-A.; after Rembrandt, London, Dulwich Pict. Gal.). In such portraits as Girl with a Veil
Henry Benbridge
Henry Benbridge born October 1743 died February 1812), early American portrait painter, was born in Philadelphia, the only child of James and Mary (Clark) Benbridge. When he was seven years old, his mother, who had been left a widow, was married to Thomas Gordon, a wealthy Scot. The boy's artistic talent was encouraged. He made decorative designs for his stepfather's drawing-room which were much admired. When he was fourteen years old he may have watched John Wollaston paint Gordon's portrait. It has been plausibly argued that young Benbridge had instruction from Wollaston, since his earliest known portrait, that of his half-sister Rebecca Gordon, "seems to hark back to Wollaston." When he was 21, Benbridge was sent to Italy, where he studied with Pompeo Batoni and Anton Raphael Mengs. In 1769, on commission from James Boswell, biographer of Dr. Samuel Johnson, he made a portrait of Pasquale Paoli in Corsica which he took to London. It was exhibited (1769) at the Free Society of Artists, and from it three mezzotints were scraped and published with the artist's name signed "Bembridge." Like other young Americans he was encouraged by Benjamin West. He wrote, on December 7, 1769, to his stepfather: "Upon my arrival I waited upon Mr. West who received me with a sort of brotherly affection, as did my cousin, Mrs. West." Impelled, apparently, by a longing to rejoin his family, he left England in 1770, bearing from West the following note of recommendation to Francis Hopkinson: "By Mr. Benbridge you will receive these few lines. You will find him an Ingenous artist and an agreeable Companion. His merit in the art must procure him great incouragement and much esteem. I deare say it will give you great pleasure to have an ingenous artist resident amongst you." Elizabeth Ann Timothy (Mrs. William Williamson), watercolor on ivory of 1775In Philadelphia Benbridge married a Miss Sage and was admitted on January 18, 1771, to membership in the American Philosophical Society, of which Benjamin Franklin was a founder. He painted the large portrait of the Gordon family, with six figures, one of his masterpieces. Suffering, however, from asthma, he sought a more congenial climate and moved to Charleston, South Carolina, where he succeeded Jeremiah Theus (d. May 18, 1774) as the popular portrait painter of South Carolina. There he made many likenesses of southern men and women, several of which have been popularly attributed to John Singleton Copley, an artist who never painted in the South and who left America in 1774. Around 1800 Benbridge settled in Norfolk, Virginia, whence he made frequent visits to his native city. At Norfolk he gave to Thomas Sully his first lessons in oil painting. He had previously instructed Thomas Coram of Charleston. Sully describes his master as "a portly man of good address - gentlemanly in his deportment." Benbridge's health is said by Hart to have declined in middle age. Dunlap's assertion that his last years were passed "in obscurity and poverty" has been disputed.
