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 :. | Ceiling decoration yy | Woman portrait | Details of Mona Lisa | Adoration of the Magi | The Baptism of Christ |

Philip Charles Hardwick
English architect , (1822-1892), was a notable English architect of the 19th century who was once described as "a careful and industrious student of mediaeval art". He was born in Westminster and was the son of the architect Philip Hardwick (1792-1870), grandson of Thomas Hardwick (junior) (1752-1825) and great grandson of Thomas Hardwick Senior (1725-1825); the Hardwicks' architectural work spanned over 100 years, making them one of the most successful architectural families in British history. Hardwick's mother was also from an eminent architectural family: the Shaws. His maternal grandfather was John Shaw Senior (1776-1832) and his uncle was John Shaw Jr (1803-1870) - both architects known for their work at Christ's Hospital and at Ramsgate harbour. Philip Charles trained under his father and also in Edward Blore's office during which time he visited Belgium and Germany. Hardwick exhibited regularly at the Royal Academy between 1848 and 1854. Like his father, Philip Charles was employed in the 'Square Mile' of the City of London, where he became the leading architect of grandiose banking offices, mainly in an Italianate manner, setting the pattern for suburban and provincial designs for almost three decades. He designed five City banks, including Drummond's in Trafalgar Square (1879-81), and was architect to the Bank of England from 1855 to 1883. However, he was more employed outside London, designing branch offices at Hull (1856) and Leeds (1862-65). His best known work was the Great Hall of London's Euston railway station (opened on 27 May 1849). The Great Hall was demolished in 1962 to make way for construction of the current Euston Station building. Philip Charles was the last Hardwick Surveyor to St Bartholomew's Hospital in London and was a major benefactor of the hospital.

Karl Nordstrom
Swedish Painter, 1855-1923 was a Swedish painter and one of the leading members of Konstnärsförbundet, which he chaired from 1896 until its dissolution in 1920. Born on Gotland, but growing up on Tjörn on the Swedish West Coast, Nordström studied at principskolan, the preparatory school of the Royal Academy of Arts in Stockholm and the private painting school of Edvard Perseus, but was never promoted to the "Antique school" of the Academy but had to continue on his own. Traveling to Paris in 1881, he was influenced by the impressionists. He spent a couple of years in Grez-sur-Loing, the site of an important colony of Scandinavian artists, practising his plein air painting in the strong French sunlight. In 1885, he joined the group of young artists protesting against the policies and leadership of the Academy, and he was ever since 1886 one of the leading members of Konstnärsförbundet, the formalization of the opposition group. He was its chairman from 1896 until its dissolution in 1920. In 1886, he married xylographer and photographer Tekla Lindeström in Paris. Later the same year, he settled on Tjörn, using what he had learnt in France about light and colours to depict the landscape where he had grown up. He spent the summer of 1889 in Visby. Around 1890, he moved from his earlier impressionism towards a more synthetist style. His influences came from Japanese art, which he had encountered in Paris, and from Gauguin, whose paintings he first saw in photographs he had received from Ivan Agueli. One of Nordström's old friends from the time at the Academy and in Perseus' school, Nils Kreuger, had lived in the city of Varberg since 1888. He convinced Nordström to move there in 1892, and they were joined by another of their old friends, Richard Bergh, in 1893.
