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 (844 scientists, as of April 2021). The next-level members are corresponding members (1079 scientists). There are also professors of the RAN (604 scientists). 3 professors became academicians and 137 professors became corresponding members. These are now counted twice: as professors and as members. The last elections were organized in November 2019. To be elected to the Academy is a great honor for any researcher.
