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 :. | Studies fur the adoration of the Konige | The Madonna of the Carnation (detail) dg | Studies of horses | You branching of the Blutgefabe, anatomical figure with heart kidneys and Blutgefaben | The Virgin and the Nino with Holy Ana |

Wilhelm Krause
Wilhelm Krause (July 12, 1833 - February 4, 1910) was a German anatomist born in Hanover. In 1854 he earned his medical doctorate, and later (1860) became an associate professor at the University of Göttingen. In 1892 he was appointed head of the Anatomical Institute Laboratory in Berlin. He was the son of anatomist Karl Friedrich Theodor Krause (1797-1868). Krause is remembered for the discovery and description of mechanoreceptors that were to become known as Krause's corpuscles, sometimes called "Krause's end-bulbs". His name is also associated with "Krause's membranes", which are isotropic bands in striated muscle fiber that consist of disks of sarcoplasm and connect the individual fibrils. In addition he performed pioneer research in the field of embryology. One of his well-known students at Göttingen was bacteriologist Robert Koch (1843-1910).
william holman hunt,o.m.,r.w.s
1827-1910 English painter. He worked as an office clerk in London from 1839 to 1843, attending drawing classes at a mechanics' institute in the evenings and taking weekly lessons from the portrait painter Henry Rogers. Holman Hunt overcame parental opposition to his choice of career in 1843, and this determined attitude and dedication to art could be seen throughout his working life. In July 1844, at the third attempt, he entered the Royal Academy Schools. His earliest exhibited works, such as Little Nell and her Grandfather (exh. British Institution, 1846; Sheffield, Graves A.G.), reveal few traces of originality, but the reading of John Ruskin's Modern Painters in 1847 was of crucial importance to Holman Hunt's artistic development. It led him to abandon the ambitious Christ and the Two Marys (Adelaide, A.G. S. Australia) in early 1848, when he realized its traditional iconography would leave his contemporaries unmoved. His next major work, the Flight of Madeline and Porphyro during the Drunkenness Attending the Revelry (1848; London, Guildhall A.G.), from John Keats's 'Eve of St Agnes', though displaced into a medieval setting, dramatized an issue dear to contemporary poets and central to Holman Hunt's art: love and youthful idealism versus loyalty to one's family. His first mature painting, it focuses on a moment of psychological crisis in a cramped and shallow picture space.
e. j. f. bendemann
Eduard Julius Friedrich Bendemann (3 December 1811, Berlin - 27 December 1889, Dusseldorf) was a German painter. Bendemann was born in Berlin. His father, Anton Heinrich Bendemann, a Jewish banker, monitored his education closely; it was one that would have naturally led him to some sort of technical occupation, but his talent and propensity towards art resulted in his being allowed to pursue other interests. His mother Fanny Eleonore Bendemann nee von Halle, also a daughter of the Jewish banker Joel Samuel von Halle. After he completed elementary school he enrolled in the Wilhelm von Schadow's School in Dusseldorf. In 1830 he went on a school trip to Italy. After a series of jobs, among them with Boas and Ruth, his talent as an artist began to show, especially with his very large 1832 painting titled, The Sad Jews of Babylon which was featured in the Berlin art exhibition. The picture garnered a great deal of attention, which was in part due to the deep and simple feeling and the noble composition of the piece (museum in Cologne). Bendemanns second picture: The Two Girls at the Well (1832), was acquired by the North Rhine-Westphalia art association. Soon thereafter followed Jeremias on the Ruins of Jerusalem for which the artist received a medal in Paris in 1837. This painting was for the most part about the progress of the Jews in Babylon. (Royal Palace in Hanover). His best known work is The Harvest. The artist's first fresco was a symbolic representation of the art at the Poetry Well at the house of his parents-in-law in Berlin. In the year 1838 he was appointed professor of the academy of arts in Dresden, where he had the opportunity to paint even larger frescos. Bendemann was given the task to decorate three halls of the Dresden royal palace, the throne room, the tower room, and the tower hall with wall paintings. In the throne room, on both sides of the throne, there are representations of important rulers and legislators in gold leaf with smaller representations in relief form below, from Moses up to Albrecht III, the King at the time. On the wall facing the throne there are four paintings depicting events from the life of King Heinrich I each with other pictures attached which explain each of the four events. Bendemann died in Dusseldorf.
