LEONARDO da Vinci
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.

(September 23, 1852 - October 24, 1917) was an American landscape, portrait and genre painter whose Impressionist style led to his recognition in the late nineteenth century as a prominent figure in American art.
Carroll Beckwith, as he preferred to be known, was born in Hannibal, Missouri on 23 September 1852, the son of N. M. Beckwith, who was United States Commissioner-General at the Paris Exposition of 1867. However, he grew up in Chicago where his father started a wholesale grocery business. In 1868 aged 16 he studied art at the Chicago Academy of Design under Walter Shirlaw until the great fire of 1871 destroyed eveything (including much of the heart of the city). He then went to New York and studied at the National Academy of Design (of which he afterwards became a member) in New York City under Lemuel Wilmarth and later traveled on to Paris, staying there from November 1873 until 1878.

Arthur Pond (1705?-1758) was an English painter and engraver.
Born about 1705, was educated in London, and stayed for a time in Rome studying art, in company with the sculptor Roubiliac. He became a successful portrait-painter.
He was elected a Fellow of the Royal Society in 1752, and died in Great Queen Street, Lincoln's Inn Fields, 9 September 1758.
His numerous original portraits include Alexander Pope, William, Duke of Cumberland, and Peg Woffington. Pond was also a prolific etcher, and used various mixed processes of engraving by means of which he imitated or reproduced the works of masters such as Rembrandt, Raphael, Salvator Rosa, Parmigiano, Caravaggio, and the Poussins.
In 1734-5 he published a series of his plates under the title Imitations of the Italian Masters. He also collaborated with George Knapton in the publication of the Heads of Illustrious Persons, after Jacobus Houbraken and George Vertue, with lives by Thomas Birch (London, 1743-52); and engraved sixty-eight plates for a collection of ninety-five reproductions from drawings by famous masters, in which Knapton was again his colleague. Another of his productions was a series of twenty-five caricatures after Pier Leone Ghezzi, republished in 1823 and 1832 as Eccentric Characters.
