Liselotte Herrmann (called “Lilo”, 23 June 1909 – 20 June 1938, executed) was a German Communist Resistance fighter in Nazi Germany.
Born in Berlin, Liselotte Herrmann, an engineer’s daughter, had a middle class liberal upbringing. After completing her Abitur exams in 1929, she went to work as a laboratory assistant in a chemical factory to prepare her studies in chemistry. Later that year, her family moved to Stuttgart, where she attended the Technical College. In 1931, she switched to biology, studying at the Frederick William University in Berlin.
Already, as a schoolgirl, she had joined the Young Communist League of Germany in 1928, and also became a member of the Red Students’ League (Roter Studentenbund). She also joined the Revolutionary Union Opposition (Revolutionäre Gewerkschafts Opposition) in 1931, and in the same year became a member of the Communist Party of Germany (KPD).
Early after the Nazi Machtergreifung in 1933, she together with 111 other students signed a “Call for the Defence of Democratic Rights and Freedoms” and was therefore reprimanded and expelled by the university on 11 July 1933. From that time, she worked illegally against Germany's Nazi dictatorship and socialized with the armed resistance within the KPD organisation.
She temporarily took a job as a nanny and on 15 May 1934, Liselotte's son Walter was born. The boy's father, a KPD official, had been slain in Gestapo custody. In September of the same year, she once again moved to Stuttgart, where she worked as a shorthand typist at her father's engineering office and re–established contacts with the banned Communist Party. From late 1934, she worked as a technical aide to the Württemberg KPD leader, Stefan Lovász, until his arrest in June 1935. She obtained information about German re-armament concerning secret weapons projects — munitions production at the Dornier aircraft factory in Friedrichshafen and the building of an underground ammunition factory (Muna) near Celle — which were relayed to the KPD's office in exile that had been set up in Switzerland.
