Stumbling block for Robert Remak in Berlin-Lichterfelde

Robert Remak studied at the Berlin University under Ferdinand Georg Frobenius and received his doctorate there in 1911. After his habilitation , he worked between 1929 and 1933 as a private lecturer at the Berlin University. After the " seizure of power " by Hitler, Remak lost his position due to his Jewish origins. After the November pogrom in 1938, Remak was arrested and imprisoned for several weeks in the Sachsenhausen concentration camp near Berlin. After his release he emigrated to the Netherlands, where he was arrested again after the occupation by German troops in 1942, deported to Auschwitz and murdered.

His doctoral thesis on the decomposition of finite groups into indirect indecomposable factors contains a set of group theory often named after him, Wolfgang Krull and Otto Juljewitsch Schmidt (which was already proven by Joseph Wedderburn in 1909). Remak also dealt with algebraic number theory.
