Aleksandr Isayevich Solzhenitsyn (11 December 1918 – 3 August 2008) was a Russian novelist, historian, and short story writer. He was an outspoken critic of the Soviet Union and communismand helped to raise global awareness of its Gulag forced labor camp system. He was allowed to publish only one work in the Soviet Union, One Day in the Life of Ivan Denisovich (1962), in the periodical Novy Mir. After this he had to publish in the West, most notably Cancer Ward (1968), August 1914 (1971), and The Gulag Archipelago (1973). Solzhenitsyn was awarded the 1970 Nobel Prize in Literature "for the ethical force with which he has pursued the indispensable traditions of Russian literature".[6] Solzhenitsyn was afraid to go to Stockholm to receive his award for fear that he would not be allowed to reenter. He was eventually expelled from the Soviet Union in 1974, but returned to Russia in 1994 after the state's dissolution.

Ivan Denisovich Shukhov has been sentenced to a camp in the Soviet gulag system. He was accused of becoming a spy after being captured briefly by the Germans as a prisoner of war during World War II. He is innocent, but is sentenced to ten years in a forced labor camp.

The day begins with Shukhov waking up sick. For waking late, he is forced to clean the guardhouse, but this is a comparatively minor punishment. When Shukhov is finally able to leave the guardhouse, he goes to the dispensary to report his illness. It is relatively late in the morning by this time, however, so the orderly is unable to exempt any more workers and Shukhov must work.

The rest of the novel deals mainly with Shukhov's squad (the 104th, which has 24 members), their allegiance to the squad leader, and the work that the prisoners (zeks) do in hopes of getting extra food for their performance. For example, they are seen working at a brutal construction site where the cold freezes the mortar used for bricklaying if not applied quickly enough. Solzhenitsyn also details the methods used by the prisoners to survive; the whole camp lives by the rule of survival of the fittest.

Tiurin, the foreman of gang 104, is strict but kind, and the squad's fondness of Tiurin becomes more evident as the book progresses. Though a morose man, Tiurin is liked because he understands the prisoners, he talks to them, and he helps them. Shukhov is one of the hardest workers in the squad and is generally well-respected. Rations are meagre at the camp, but they are one of the few things that Shukhov lives for. He conserves the food that he receives and is always watchful for any item that he can hide and trade for food at a later date.

At the end of the day, Shukhov is able to provide a few special services for Tsezar (Caesar), an intellectual who does office work instead of manual labor. Tsezar is most notable, however, for receiving packages of food from his family. Shukhov is able to get a small share of Tsezar's packages by standing in lines for him. Shukhov reflects on his day, which was both productive and fortuitous for him.
