Siegfried Seidl

Siegfried Seidl (24 August 1911 in Tulln, Austria-Hungary – 4 February 1947 in Vienna) was an Austrian career officer and World War II Commandant of the Theresienstadt concentration camp located in the present-day Czech Republic. He also was commandant of the Bergen-Belsen, and later served as staff officer to Adolf Eichmann. After the war, in 1947, he was tried in Austria and convicted as a war criminal; sentenced to death, he was executed by hanging.

Siegfried Seidl was born in Tulln an der Donau (Tulln on the Danube), then part of the Austro-Hungarian Empire, now in Lower Austria. After completing his secondary schooling at the Oberschule, Seidl started law study. After three semesters, he interrupted his studies and took on various odd jobs.

From 1935 until 1938, Seidl studied history and German studies at the University of Vienna. He obtained his PhD in 1941. This title was taken away from him in 1947 after he was convicted as a war criminal.

On 2 March 1939 Seidl married Elisabeth Stieber, a former teacher in a kindergarten. She was a member of the NSDAP (Nazi Party) and its NS-Frauenschaft (NSF: National Socialist Women's League, literally NS-Womanship), and supporting member of the SS.

On 15 October 1930 Seidl joined the Nazi Party (registered as member number 300,738). From September 1931 until May 1932, he was active in the SA. The same day that he left the SA, Seidl was assigned to the 11th SS-Standarte (SS-regiment) as Oberscharführer (equivalent to Staff Sergeant (US) or Sergeant (UK)) (member number 46,106).
