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.

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. Grace Hudson(1865 - 1937) was an American painter. She was nationally known during her lifetime for a numbered series of more than 684 portraits of the local Pomo Indians. She painted the first, "National Thorn", after her marriage in 1891, and the last in 1935.
Grace Carpenter was born in Potter Valley, California. Her mother was one of the first white school teachers educating Pomo children and was a commercial portrait photographer in Ukiah, California; her father was a skilled panoramic and landscape photographer who chronicled early Mendocino County frontier enterprises such as logging, shipping and railroading. At fourteen years of age, Grace was sent to attend the recently-established San Francisco School of Design, an art school which emphasized painting from nature rather than from memory or by copying existing works. At sixteen, she executed an award-winning, full length, life sized self-portrait in crayon. While in San Francisco, she met and eloped with a man fifteen years her senior named William Davis, upsetting her parents and ending her formal studies. The marriage lasted only a year.
From 1885 to 1890, Grace Carpenter Davis lived with her parents in Ukiah painting, teaching and rendering illustrations for magazines such as Cosmopolitan and Overland Monthly. Her work at that time had no particular focus and included genre, landscapes, portraits and still lifes in all media. Later in her career she would continue to accept occasional magazine illustration assignments including ones for Sunset.
Louis HayetFrench, 1864-1940.French painter and writer. He was largely self-taught and initially earned his living as an itinerant painter-decorator. In 1881 he met Lucien and Camille Pissarro while painting landscapes near Pontoise and through them met Paul Signac in 1885 and Seurat in 1886. After a years military service at Versailles, Hayet moved to Paris in the autumn of 1887. There he began to apply to his paintings Eug?ne Chevreuls theories of colour contrast with which he had become familiar by 1881. A gifted watercolour painter, he also experimented with the ancient technique of wax encaustic, painting on a prepared cotton that allowed light to filter through. The paint surface of works such as The Grange (Beauchamp, France, priv. col., see 1983 Pontoise exh. cat., no. 1) retains a vivid tonal freshness, while the subject of crowds of peasants gathered before the Paris agricultural market reveals a debt to Pissarro. During the second half of the 1880s he became obsessed with the notion of passage
