Born in 1922, Hildegard Löwy was the youngest member of the Baum Gruppe, a mainly Jewish resistance group against the Nazis. She had firm Zionist and pacifist principles and believed communism was the best way for Jews to obtain equal rights. Arrested in April 1942, Löwy tried to escape from prison but was ultimately convicted of Communist treason and executed in a Berlin prison.

Formally created in 1938 and 1939, the Baum group was a German anti-Fascist resistance organization. Initially its work consisted of making and distributing anti-Fascist propaganda, but on May 18, 1942, the Baum group joined the effort to set fire to an anti-Soviet exhibit at a public park in Berlin. The damage was minimal and shortly thereafter, the Gestapo arrested hundreds of Jews in retaliation and twenty-two members of the Baum group were executed.
