Dostoevsky was a Russian author born in 1821 in Moscow. He came from a poor family background and lost both his parents by the age of 16. In 1849, he was arrested and sentenced to death for being part of a radical intellectual group, but his sentence was later commuted to hard labor in Siberia. This experience had a profound impact on Dostoevsky and led him to reject his former liberal political views. He is now considered one of the founders of existentialism and his works often featured characters who grappled with existential questions through suffering. Some of his most famous novels include Crime and Punishment and The Brothers Karamazov.
