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.

Francois Bonvin Location
Bonvin was born in humble circumstances in Paris, the son of a police officer and a seamstress. When he was four years old his mother died of tuberculosis and young Francois was left in the care of an old woman who underfed him. Soon his father married another seamstress and brought the child back into the household. Nine additional children were born, putting a strain on the familys resources, and to make matters worse his stepmother took to abusing and undernourishing Francois.
The young Bonvin started drawing at an early age. His potential was recognized by a friend of the family, who paid for him to attend a school for drawing instruction at age eleven. This instruction ended after two years, when his father apprenticed him to a printer, and Bonvin was to remain mostly self-taught as an artist. He spent his free time at the Louvre where he especially appreciated the Dutch old masters. Bonvin married a laundress at the age of twenty, at about the same time that he secured a job at the headquarters of the Paris police. It was during this period in his life that he also contracted an illness which would trouble him for the rest of his life.
Bonvin exhibited three paintings in the Salon of 1849, where he was awarded a third-class medal. He exhibited in the Salon of 1850 with Courbet, and won recognition as a leading realist, painting truthfully the lives of the poor which he knew at first hand. His paintings were well received by critics and by the public. Although his work had elements in common with Courbets, his modestly scaled paintings were not seen as revolutionary. He was awarded the Legion d honneur in 1870.
His subjects were still life and the everyday activities of common people, painted in a style that is reminiscent of Pieter de Hooch and Jean-Baptiste-Simeon Chardin. It is the latter who is especially recalled by Bonvins delicate luminosity.
In 1881 he underwent an operation which did not restore him to health, and he became blind. A retrospective exhibition of his work was held in 1886. He died at Saint-Germain-en-Laye in 1887. Hans Muelich
