A former Lutheran pastor, Gauck came to prominence as an anti-communist civil rights activist in East Germany. During the 1989 revolution, he was a co-founder of the New Forum opposition movement in East Germany, which contributed to the downfall of the Socialist Unity Party of Germany (SED). In 1990 he served as a member of the only freely elected People's Chamber for the Alliance 90. Following German reunification, he was elected by the Bundestag as the first Federal Commissioner for the Stasi Records, serving from 1990 to 2000. As Federal Commissioner, he earned recognition as a "Stasi hunter" and "tireless pro-democracy advocate," exposing the crimes of the communist secret police.
