Judith Vallentin was born in Zurich; the family lived in Berlin from 1906. After her parents' death, she grew up with friends of the family. She completed school and went to university but had to abandon her studies for financial reasons. She joined the Communist Youth Federation as a student; it was there that she met Erich Auer. The couple married in 1926, with their daughter Ruth born three years later. After the National Socialists took power, Judith and Erich Auer were active in the banned communist movement. In 1942 Judith Auer joined the group formed around Anton Saefkow; she was a close friend of his wife Aenne. She hid Franz Jacob in her home on several occasions while he was on the run, at the end of 1942 and the beginning of 1944. As a purchaser in Berlin's Oberspree Cable Works, she could use work trips to pass on information and material between resistance groups in Berlin and Jena. She was arrested in July 1944, sentenced to death by the "People's Court" on September6, 1944, and murdered in Berlin-Plötzensee on October27, 1944.
