Life
Since his father was of German descent, Triewald first attended the German school in Gamla stan . After graduating from school, he started trading in unspecified goods, but failed to pull back. On a subsequent trip to England, which was to last a total of ten years, he was initially employed by a merchant Rodley and was appointed inspector of his coal mines in Newcastle in 1716 . There he acquired knowledge of steam engines , the power of which was used for dewatering and coal extraction . By the time he returned to Sweden in 1726, he had repeatedly improved the machines in the English coal mines. He also used his knowledge in Sweden. In the iron ore mines of Dannemora , he had Sweden's first steam engine built, which was used for dewatering.
In 1728 and 1729 he gave lectures in physics and mechanics at Riddarhuset , which some councilors and councilors also heard. As early as 1729 he was appointed a member of the Royal Society of Sciences in Uppsala and shortly thereafter also gained access to the Royal Society in London . In 1739 he founded the “Royal Swedish Academy of Sciences” together with Carl von Linné , Jonas Alströmer , Anders Johan von Höpken , Sten Carl Bielke and Carl Wilhelm Cederhielm .
In 1729 he started a diving company. In 1734 he wrote the treatise "The art of living under water" ( Konsten At Lefwa under Watn ), in which he described diving with open diving bells , continued in 1741 as "The planning of the art of living under water" ( Plägning Til Konsten At Lefwa under Watn ).
The farm he had built on Mälaren in Stockholm still exists.
