Recent studies of the archival documents of the bas-relief portrait kept in the Mining Museum have shown that for 130 years it was part of the decorations of the Conference Hall, and that it entered the museum's collection in 1805. It also turned out that the author of the portrait was P.A. Soimonov, a senator, one of the prominent figures of Russian history of the late 18th century, the fifth director of the Mining Institute, who made a great contribution to the development of the Mining Institute and its museum.
