Ludwig Schwartz (1822–1894) was a Russian astronomer, explorer of Eastern Siberia and the Far East, a laureate of the Demidov Prize, member of the Russian Geographical Society and the Russian Astronomical Society.
On the recommendation of Academician V. Struve, he was assigned for the position of an astronomer in the Transbaikal Expedition of N. Agte. In addition to participating in the compilation of the final map, Schwartz discovered and characterized Verkhnezeyskaya Plain, and also the Turan Ridge in cooperation with topographer S. Krutiv and draughtsman A. Argunov; besides, he acquired the first information about the Aldan Mountains.
In 1858, in the central part of the Western Sayan Mountains, on the right bank of the Yenisei, Schwarz discovered five short mountain ranges. On the basis of the gained materials, he compiled a detailed map of the Transbaikal and the Amur territories, which for a long time served as the only basis for further exploration of these regions.
After the expedition had been accomplished, Ludwig Schwarz was the Director of the Derpt Observatory and a professor of astronomy at the local university.
The main illustration shows the bust of L. Schwartz by sculptor A. Chebanenko against the background of a map of his travels and the RGS logo; the commemorative stamp features images symbolizing the geographic projects.
