Who Was Volosianov?

The late 19th and early 20th centuries were the heyday of linguistics modern logic and the philosophy of language throughout Europe. Many Russian thinkers were deeply interested in these developments including the central figure of this episode Volosianov. The only really sourced claims about any part of his life that I've really been able to find is from a 2017 paper which is titled Valentin Nicolaita Vichvalloshenov documented details of his life and works by two Brazilian scholars. He did research and taught at the Institute of Comparative Histories and of literatures and languages of east and west.
