I am impressed that one of my correspondents knew Roman Jakobson before his death in Boston in 1982.
I have been trying to find out more about Jakobson’s involvement in Russian avant-garde culture after the Revolution. The answer is that he was indeed in Moscow at the time of the Revolution, where he was a student in the Historico-Philological Faculty, received his Master’s degree in 1918, and was involved in the Moscow Linguistic Circle which developed the study of semiotics. He didn’t last long because he migrated to Prague in 1920. He remained till 1939, when he fled to Copenhagen then Norway and Sweden, where he studied aphasia, before crossing the Atlantic on a boat with Ernst Cassirer, to join the New School with Lévi-Strauss.
Quite a life.
