Libertas "Libs" Schulze-Boysen, born Libertas Viktoria Haas-Heye was a German aristocrat and resistance fighter during the Nazi regime. From the early 1930's to 1940, Libs attempted to build a literary career, initially as a press officer and later as a writer and journalist. Initially sympathetic to the Nazis as her family has close links to the senior levels of the regime, she changed her mind after meeting and marrying Luftwaffe officer Harro Schulze-Boysen.
Starting in about 1935, the couple held regular discussion meetings with their friends, that would end as a party. As an aristocrat, Libs had contact with many different people in different strata of German society, which enabled her to recruit left-leaning members into the group. Through these discussions, resistance to the Nazi regime grew and by 1936, she and Harro began to actively resist the Nazis.
