David Rousset (18 January 1912 in Roanne, Loire – 13 December 1997) was a French writer and political activist, a recipient of Prix Renaudot, a French literary award.
A survivor of the Neuengamme concentration camp and the Buchenwald Nazi concentration camp, he is famous for his books about concentration camps.Rousset was the first person to use the term "Gulag" in the French language, revealing to the French the Soviet system of labor camps.
In 1949, learning that while the concentration camps in Nazi Germany had been destroyed, camps still existed in the Soviet Union, he appealed to former inmates of Nazi camps to form a commission to inspect the USSR camps, which became the "International Commission Against Concentrationist Regimes".
For his efforts he was attacked by Pierre Daix in the French communist newspaper Les Lettres Françaises, which accused him of slandering the Soviet Union, forging the texts of the Soviet laws, and spreading misinformation.
