Russian Academy of Sciences
Like the French Academy of Sciences and unlike The Royal Society in Britain, the Russian Academy of Sciences has two types of membership. The top-level members are academicians (860 scientists, as of April 2023). The next-level members are corresponding members (1113 scientists). There are also professors of the RAN (715 scientists). 16 professors became academicians and 163 professors became corresponding members. These are now counted twice: as professors and as members. The last elections were organized in May-June 2022. To be elected to the Academy is a great honor for any researcher.
