Rudolf Brazda was the last known concentration camp survivor deported by Nazi Germany on charges of homosexuality. Brazda spent nearly three years at the Buchenwald concentration camp, where his prisoner uniform was branded with the distinctive pink triangle that the Nazis used to mark men interned as homosexuals. After the liberation of Buchenwald, Brazda settled in Alsace, northeastern France, in May 1945 and lived there for the rest of his life.

Buchenwald was a Nazi concentration camp established on Ettersberg hill near Weimar, Germany, in July 1937. It was one of the first and the largest of the concentration camps within Germany's 1937 borders. Many actual or suspected communists were among the first internees.
