Which Nobel laureate and dissident exposed the harsh realities of the Soviet labor camp system in works such as One Day in the Life of Ivan Denisovich and The Gulag Archipelago?

Aleksandr Solzhenitsyn

Solzhenitsyn spent years in the camps himself, and his writings were instrumental in informing the West about Soviet human rights abuses. He was eventually expelled from the Soviet Union in 1974 and lived in exile for two decades.
