A founding member of the IRAO, Savelev was one of Imperial Russia’s premier numismatists. An inattentive student in the classroom, he developed a love for coins that moved well beyond simply collecting them. His forte was Muslim coins, and he pioneered in analyzing them to chart historical movements and interactions. He published a survey even of Georgian antiquities in ZhMNP, vol. 16 (1837): 531-44.
Aspelin hails as the Father of Finnish Archeology, having organized both the first professional society and museum dedicated to the subject. Particularly noteworthy are his studies of the ancient Finno-Ugric tribes, from Siberia to Karelia.
