MÃ¥rten Triewald

Mårten trie forest (* November 18, 1691 in Stockholm; † August 8, 1747 ) was a Swedish merchant, engineer and co-founder of the Royal Swedish Academy of Sciences.

Life

Since his father was of German origin, Trie forest first attended the German School in Gamla stan. After leaving school entered the trade with unspecified goods, but withdrew even failures back. On a subsequent trip to England that was to last for ten years, he was initially set at a merchant Rodley and was appointed inspector of its coal mines in Newcastle still 1716. There, he acquired knowledge of steam engines whose power were used for coal mining and transportation. Until his return to Sweden in 1726, he had improved the machines in the English coal mines again. In Sweden, he used his knowledge. In the iron ore mines of Dannemora he built Sweden's first steam engine, which was used for bilge pumps.

In 1728 and 1729 he lectured in physics and mechanics in the Noblemen, which also listened to some councilors and imperial councils. Already in 1729 he was appointed a member of the Royal Society of Sciences in Uppsala and gained a little later access to the Royal Society in London. In 1739 he founded together with Carl Linnaeus, Jonas Alströmer, Anders Johan von Höpken, Sten Carl Bielke and Carl Wilhelm Cederhielm the " Royal Swedish Academy of Sciences".

In 1729 he founded a diving company and wrote the essay " The art of living under water " ( Konsten att lefa under watn ) in which he described the diving with open diving bells. The farm, which he had built in Stockholm at Mälaren, still exists.
