Erica Wallach (1923 - 22 December 1993) was a German political activist and teacher. A strong opponent of totalitarianism in Europe, she was held in a Soviet prison for five years during the peak of the Cold War due to suspicions of espionage.[1] Wallach fought against military dictatorship in Spain, Nazism in Germany, and authoritarian communism in the Soviet Union. She published the memoir Light at Midnight in 1967.
