Ruth Elfriede Hildner (1 November 1919 – 2 May 1947) was a guard at several Nazi concentration camps during World War II.
In December 1944, she arrived at Helmbrechts, a tiny subcamp of Flossenbürg located near Hof, Germany.
Hildner was one of several guards on the death march who took part in mistreatment and murder of several young girls with her baton.
Hildner melted into the hordes of refugees, escaping temporarily, but was recognized by Czechoslovakian police in March 1947, arrested, and put in prison.
[citation needed] On 2 May 1947, aged 27, she was tried in the Extraordinary People's Court in Písek, Czechoslovakia, found guilty of war crimes and hanged the same day.
