Leonardo Da Vinci
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.

English Romantic Painter, 1775-1851, British land- and seascape artist. Born in London the son of a barber, Turner was precociously talented. He entered the RA Schools in 1789, had a drawing exhibited at the academy in 1790, and was elected a full academician in 1802. He became professor of perspective in 1807. A prolific artist of amazing range of subject and style, he began work in water-colours, quickly founding both a reputation and a fortune, which made him independent of changing public taste. His work was not appreciated by everyone, but his supporters included Thomas Lawrence, John Ruskin, and the earl of Egremont. He died in eccentric obscurity under a false name. Robert Dampier
(1799 - 1874) was a British artist and clergyman.
Dampier was born in 1799 at the village of Codford St Peter in Wiltshire, England He was baptised on the 20th of Dec. 1799 (LDS IGI record batch # C014402). He was one of 13 children of Codford St Peter's rector Reverend John Dampier (1763-1839) and his wife Jane. In 1819 he went to Rio de Janeiro in Brazil as a clerk. In 1825, he was picked up in Rio to be the expedition artist on the English ship HMS Blonde under the command of Captain George Anson Byron. The ship was returning the bodies of King Kamehameha II and Queen Kamemalu to the Hawaiian islands (known by the British as "Sandwich Islands"), after both died from measles during a visit to England. Robert Dampier spent 11 weeks in Hawaii painting portraits in oil paint and making pencil drawings of landscapes.
After returning to England, he studied law at Cambridge University and then was ordained in the Church of England. He married Sophia Francis Roberts in 1828. In 1837 he became rector of Langton Matravers church. Circa 1843 they had a daughter Juliana Sophia, His wife Sophia died in 1864, and he married again in 1872. He had a daughter Frederika from the second marriage. Although employed a rector, he continued to sketch until his death in 1874.
Major works by Robert Dampier are held by the Honolulu Academy of Arts and Washington Place, also in Honolulu, Hawaii.
(10 February 1848 - 25 February 1936) was a Belgian painter, born in Saint-Vaast, Hainaut. Anna Boch died in Ixelles in 1936 and is interred there in the Ixelles Cemetery, Brussels, Belgium.
Boch participated in the Neo-Impressionist movement. Her early works used a Pointillist technique, but she is best known for her Impressionist style which she adopted for most of her career. A pupil of Isidore Verheyden, she was influenced by Theo van Rysselberghe whom she met in the Groupe des XX.
