Fyodor Dostoyevsky (born November 11 [October 30, Old Style], 1821, Moscow, Russia—died February 9 [January 28, Old Style], 1881, St. Petersburg), Russian novelist and short-story writer whose psychological penetration into the darkest recesses of the human heart, together with his unsurpassed moments of illumination, had an immense influence on 20th-century fiction.
Dostoyevsky is usually regarded as one of the finest novelists who ever lived. Literary modernism, existentialism, and various schools of psychology, theology, and literary criticism have been profoundly shaped by his ideas. His works are often called prophetic because he so accurately predicted how Russia’s revolutionaries would behave if they came to power. In his time he was also renowned for his activity as a journalist. More bio and photo source here
