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.

(1817 -1878 ) - Painter
(July 30, 1882 - October 27, 1922) was a Texan Impressionist painter, often called "the father of Texas painting."
Julian Onderdonk was born in San Antonio, Texas, to Robert Jenkins Onderdonk, a painter, and Emily Gould Onderdonk. He was raised in South Texas and was an enthusiastic sketcher and painter. As a teenager Onderdonk was influenced and received some training from the prominent Texas artist Verner Moore White who also lived in San Antonio at the time. He attended the West Texas Military Academy, graduating in 1900.
At 19, with the help of a generous neighbor, Julian left Texas in order to study with the renowned American Impressionist William Merritt Chase. Julian's father, Robert, has also once studied with Chase. Julian spent the summer of 1901 on Long Island at Chase's Shinnecock School of Art. He studied with Chase for a couple of years and then moved to New York City to attempt to make a living as an en plein air artist. While in New York he met and married Gertrude Shipman and they soon had a son.
Onderdonk returned to San Antonio in 1909, where he produced his best work. His most popular subjects were bluebonnet landscapes. Onderdonk died on October 27, 1922 in San Antonio.
President George W. Bush decorated the Oval Office with three of Onderdonk's paintings. The Dallas Museum of Art has several rooms dedicated exclusively to Onderdonk's work.
