  abstract  = {The contact between Leopold von Buch and Johann Wolfgang von Goethe was full of misunderstandings and critical skepticism. Personal discussions on geological topics failed, letters were dispatched late or did not reach the addressee. Goethe refused Buch as an "ultra-volcanist," Buch labelled Goethe as incompetent. The failed encounter issued in a correspondence of just two letters presented here.},

  abstract  = {The article provides historical background for Alexander von Humboldt's expedition into Russia in 1829. It includes information on Humboldt's works and publications in Russia over the course of his lifetime, as well as an explanation of the Russian scientific community's response to those works. Humboldt's ideas on the existence of an active volcano in Central Asia attracted the attention of two prominent Russian geographers, P. Semenov and P. Kropotkin, whose views on the nature of volcanism were quite different. P. Semenov personally met Humboldt in Berlin. P. Kropotkin made one of the most important geological discoveries of the 19th Century: he found the fresh volcanic cones near Lake Baikal. Soon after Humboldt's Russian expedition, and partly as a result of it, an important mineral was found in the Ilmen mountains - samarskite, which later gave its name to the chemical element Samarium, developed in 1879. At the beginning of the 20th Century, the Russian scientist V. Vernadskiy pointed out that samarskite was the first uranium-rich mineral found in Russia.},
