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 :. | You branching of the Blutgefabe, anatomical figure with heart kidneys and Blutgefaben | Rule fur the proportion of the human figure | Virgin of the Rocks | Mona Lisa | Portrait of Ginevra de' Benci sg |

Anna Elizabeth Klumpke
1856-1942 Anna Elizabeth Klumpke (October 28, 1856?C1942) was American portrait and genre painter born in San Francisco, California, United States. She is perhaps best known for her portraits of famous women including Rosa Bonheur and Elizabeth Cady Stanton (1889). Her father, John Gerald Klumpke, born in England or Germany , was a successful and wealthy realtor in San Francisco. Her mother was Dorothea Mattilda Tolle. Anna was the eldest of eight children, five of whom lived to maturity. Among her siblings were the astronomer Dorothea Klumpke-Roberts, the violinist Julia Klumpke, and the neurologist Augusta D??jerine-Klumpke. At age three, Anna fell and suffered a fracture of her femur. She fell again at age five and suffered osteomyelitis with purulent knee arthritis. It handicapped her, and her mother took extraordinary means to remeded the problem by taking Anna and three siblings to Berlin for treatment by Dr. Bernhard von Langenbeck. The treatments lasted 18 months, including thermal baths at Kreuznach, but unfortunately they were not successful, and she would remained hobbled all her life. While in Europe, her mother ensured that all of her children had excellent tutoring. The time away in Europe placed a strain on the relationship of her parents. When Anna was fifteen, her parents divorced. She and her siblings (now numbering five) moved with their mother to Göttingen, Germany, where they lived for a time with Mattilda's sister, who had married a German national. Anna and her sister Augusta were sent to school at Cannstatt, near Stuttgart. At age seventeen, the family moved to Clarens, near Lake Geneva in Switzerland where she spent two years in boarding school. She studied art at home for the next few years, and in October 1877, moved with her family once more to Paris, where she was later enrolled in the Julian Academy (1883-1884), under the tutelage of Tony Robert-Fleury and Jules Lefebvre. At one point she also studied under Vuillefroy. She presented her first work at the Paris Salon in 1884, while still at the Academy, and she won the grand prize for outstanding student of the year. She showed regularly at the Salon for several more years.
