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 :. | Madonna of the Rocks | The Baptism of Christ | The Annunciation-o | Studies for a Nativity | Study of a child |

Adam Chmielowski
1845-1916) was a Polish religious brother and founder of the Albertines. He is a saint of the Catholic Church. Albert is also known as Brat Albert (Brother Albert); in recognition of his holiness he has also been called the "Brother of Our Lord", "Brother of Our God", and "Our God's Brother". Adam Chmielowski was born to a wealthy aristocratic family, and initially studied agriculture with the intention of managing the family estate. Involved in politics since his youth, he lost a leg at the age of 17 while fighting in an insurrection. He became a well-known and well-liked artist in Krakew, his political convictions inspiring his interest in the human condition. A gentle and compassionate spirit, Chmielowski felt compelled to help those in need and after years of reflection, decided to follow his calling into the service of God. In 1880, Chmielowski joined the Jesuits, took up the name Albert and abandoned painting. He began a life of service to the poor. In 1887, he founded the Brothers of the Third Order of Saint Francis, Servants of the Poor, known in honor of their founder as the Albertines or the Gray Brothers, after their rough gray habits. In 1891, he founded the women's congregation, the Gray Sisters. The Albertines organized food and shelter for the poor and homeless.

Abraham Wuchters
Abraham Wuchters (1608 - 23 May 1682) was a Dutch-Danish painter and engraver. He was born in Antwerp but had most of his career in Denmark where he, along with Karel van Mander III, was the preferred painter of the Danish King, nobility and Bourgeoisie during his day, together they represent the main influence from the Dutch Golden Age on Danish Baroque art. Wuchters was born in Antwerp in 1608. He arrived in Denmark in 1638 and was, the following year, employed as sketching master at Sorø Academy. Around the same time, he was summoned to Copenhagen where he painted several portraits of King Christian IV. In 1645 he returned to Copenhagen Castle to portray the King's children, including lrik Christian Gyldenløve (c. 1645, Danish National Gallery) and Duke Frederik (III) (c. 1645, Amalienborg Palace). In two periods, between 1658 and 1662, he worked at the Royal Swedish Court in Stockholm where he portrayed Queen Consort Christina (1660, Uppsala University and 1661, Stockholm Castle), Charles X Gustav and Hedvig Eleonora. Back in Denmark, Wuchters was engaged by Frederick III, who had instituted Denmark as an absolute monarchy in 1660, with responsibility for the maintenance of his paintings. n 1671 the new king, Christian V, appointed him as official Painter to the Danish Coirt and in 1873 he was also made official Engraver to the Danish Court. It was, therefore, he alone who decided how the face of the absolutist King was to be represented.
