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 :. | Annunciation (detail) ey79 | Madonna with the Yarnwinder | Madonna and Child with a Pomegranate et | The annunciation | The Refectory with the Last Supper after restoration g |

Samuel Thomas Gill
(Devon, England 1818 - Melbourne 1880 ) Australian/British Artist Australian/British Artist,also known by his signature S.T.G., was and English-born Australian artist. Gill was born in Perriton, Somerset, England, son of the Reverend Samuel Gill, a Baptist minister, and his first wife, Winifred Oke. Rev. Gill became the headmaster of a school at Plymouth, where the son was first educated, then he continued to Dr Seabrook's Academy, Plymouth. Having moved to London, Gill was employed as a draughtsman and watercolour painter by the Hubard Profile Gallery, before departing for the colony of South Australia in 1839 with his parents, arriving in December. Gill arrived in Adelaide, aged 21 and established a studio in 1840, and called for those 'desirous of obtaining a correct likeness' of themselves and their families, friends, animals and residences to contact him. His activities soon expanded to include street scenes and public events, including the newly discovered copper mines at Burra Burra as well as the departure of Charles Sturt's expedition for the interior on 8 October 1844.
Henry Bacon
1839-1922 Henry Bacon Gallery Henry Bacon was born in Watseka, Illinois to father civil engineer Henry Bacon and mother Elizabeth Kelton Bacon, both of Massachusetts. Bacon was largely raised in Wilmington, N.C., where his father settled down and served as a government engineer in charge of the Cape Fear River improvements. At age 15, Henry Bacon was sent north to Boston's Chauncey Hall School. In 1884 he matriculated at the University of Illinois at Urbana-Champaign, but left within a year to launch an architectural career in the office of Chamberlin & Whidden in Boston as a draftsman. Bacon was soon hired into the office of famed McKim, Mead & White in New York City, the best-known American architectural firm of its time. While at McKim, Mead & White (MMW), Bacon won, in 1889, the Rotch Traveling Scholarship for architectural students, which gave him two years of study and travel in Europe, learning and drawing details of Roman and Greek architecture as far afield as Turkey, where he met his future wife, Laura Florence Calvert, daughter of a British Consul. He traveled with another fellowship student, Albert Kahn who would become a leading industrial architect. Returning to the U.S. he spent a few more years with his mentor, McKim, working on projects like the Rhode Island State House in Providence, Rhode Island, and serving as McKim's personal representative in Chicago during the World's Fair in Chicago, where MMW was at work designing certain buildings for the World's Fair. In 1897, Bacon left the office of McKim, Mead & White (MMW) to found, with a younger MMW architect James Brite, a new partnership Brite and Bacon Architects, where Brite was in charge of financial, administrative, and contracting aspects of the partnership, while Henry Bacon was in charge of the architectural design and construction. The partnership immediately won the competition for the Jersey City Public Library, the Hall of History for the American University at Washington, DC, and thereafter built a good number of public buildings and a small number of private residences. The partnership was selected to build two private residences in 1897, the "La Fetra Mansion" in Summit, New Jersey, and a three-story Georgian mansion "Laurel Hill" in Columbia, NC. The "La Fetra Mansion" was completed by the partnership sometime during 1899 to 1900, and published in the September 1901 issue of The Architecture, the pre-eminent architectural professional journal of its time. The LeFetra Mansion fully exhibits Bacon's Greek and Roman architectural predilections, his simple, austere, elegant lines, and his skill in dimensions and proportions that give rise to a feeling of the presence of divine spirituality, peaceful tranquility, and a sense of divine protection. While the La Fetra Mansion in Summit, NJ bears Bacon's signature style, the Georgian Mansion "Laurel Hill" was most probably designed by Brite.
