Auer was born in Zürich. Her father was the communist writer, Erich Vallentin. After her parents' untimely death in 1917, Judith was brought up by a well-to-do Jewish family. She completed her Abitur and began studies in music in the hopes of becoming a pianist.
In 1924, as a student, she joined the Young Communist League of Germany, and the next year, moved to Berlin. There, she met and married Erich Auer, a functionary in the Communist Party of Germany (KPD), in 1926. In 1927, she joined the KPD. In 1928, Auer went to Moscow with her husband and worked at the Comintern's offices.
After Hitler seized power in Germany in 1933 and the KPD was banned by the new régime, Auer eventually found herself working for AEG at the Kabelwerk Oberspree ("cable works"), first as a shorthand typist, and later as a buying agent. It was here that Auer first came into contact with the resistance group around Fritz Plön, a welder, who himself had contacts with the resistance group around Anton Saefkow, Franz Jacob, Bernhard Bästlein and Karl Klodt, the Saefkow-Jacob-Bästlein Organization. Auer also had had a long friendship with Änne Weiß, who became Saefkow's wife.
Auer managed her resistance group's finances and used business trips to do courier work, especially with a view to establishing links with resistance fighters in Thuringia, such as Theodor Neubauer. She also hid Franz Jacob in her flat for several months after he fled from Hamburg.
Arrest and Execution
Auer was arrested at her workplace on July 7, 1944 and was later tortured. Along with Bruno Hämmerling and Franz Schmidt, she was sentenced to death at the Volksgerichtshof. Auer was hanged at Plötzensee Prison in Berlin on October 27, 1944.
