Wilhelm Ludwig von Eschwege
Eschwege came from the noble family of the von Eschwege belonging to the Althessian knighthood and was born in the Aue mansion . He was a son of the district administrator and manor owner Johann Christian Ludwig von Eschwege (1746–1798) and his wife Sophie, née. Mosebach (1753-1813). In 1823 he married Sophie von Baumbach (1785–1869), daughter of the Hessian district administrator Ludwig Wilhelm von Baumbach (1755–1811) and his wife Christiane von Wangenheim (1764–1841). The marriage remained childless.
After an initial education by private tutors, he attended grammar school in Eisenach and then from 1796 to 1799 the Georg-August University in Göttingen . There he was u. a. Student of Johann Friedrich Blumenbach and fellow students of Friedrich Konrad Hornemann , Georg Heinrich von Langsdorff and Johann Kaspar Horner . After completing his studies in 1801 he was employed as a mining authority assessor in Richelsdorf in Hesse, but in 1803 he went to Portugal as director of an ironworks .
During the invasion of Portugal by Napoleonic troops in 1807, Eschwege was captain of the artillery in the Portuguese army. In 1809 he followed the exiled royal family to Brazil , where over the next ten years he set up a total of 29 ironworks , especially in the state of Minas Gerais . In December 1812, he brought Brazil's first iron to the river in the ironworks in Congonhas do Campo . In 1817 he was appointed general director of the Brazilian gold mines and head of the royal (from 1822 imperial) minerals cabinet in Rio de Janeiro . Eschwege used his stay in Brazil to travel the country and do geognostic research. He became one of the most thorough diamond connoisseurs of his time, drew the first profiles and the first colored geological map of Minas Gerais, and published the results of his explorations in numerous publications.
In 1821 he returned to Europe, and from 1823 to 1830 he worked again in Portugal, where from 1824 he was chief miner and genius at the head of the mining industry . In 1830 he was forced to leave Portugal by the political situation under the usurper Michael I. He went back to Hesse and founded the "Hessisch-Waldeckische Compagnie for the extraction of gold from the Edder River" in Kassel in 1832. Prince Elector and co-regent Friedrich Wilhelm von Hessen-Kassel and Prince Georg II. Heinrich von Waldeck took part as shareholders and "highest protectors", and a number of Hessian and Waldeck nobles as well as respected citizens of the region became shareholders. The company built Europe's largest gold panning facility at the time on the Eder near Bergheim , but the expensive company was a flop because it did not produce gold nuggets , but only the finest gold leaves, and went into liquidation in May 1835 .
In 1834 Peter IV called him back to lead the mining industry in Portugal and appointed him major general of the genius corps . He was the Portuguese chief miner until the dissolution of this office in 1836. After that, he stayed in Portugal to secure his traditional rights. 1839–1849 he built the palace Palácio Nacional da Pena near Sintra at the behest of the Portuguese prince consort and titular king Ferdinand II .
