Two letters from the Elhuyar brothers
Brothers Joan Jose and Fausto Elhuyar have found a letter in the German organization Bergakademia in Freiberg. One of them is May 10, 1782. Sent by Juan José Elhuyar from the Swedish Uppsala to professor and friend Abraham GottededWerner to Freiberg. Meanwhile, Fausto Elhuyar, waiting for his departure to Mexico, sent him from Cadiz on June 2, 1788 to the same professor in Germany.
The theme of both letters is primarily mineralogy, but as John Joseph sent Werner from Uppsala, he clarifies a point that until recently has been dark. There are those who think that Fausto was the one who learned mineralogy with the prestigious chemist Uppsalan Tobern Bergman, but since the letter of Joan José is made in Uppsala, he was a student of Bergman whenever he was one of his brothers).
