He Begged for Mercy: The Fate of Theresienstadt Camp Commandant – Siegfried Seidl
Background And Seidl’s Rise
Siegfried Seidl was born on August 24, 1911, in Tulln an der Donau, Austria. He grew up in the chaotic aftermath of the Austro-Hungarian Empire’s collapse and the rise of radical nationalism. At age 19 (1930), Seidl joined the Nazi Party (NSDAP), later the SA and SS – very early, before Austria was annexed into Nazi Germany (Anschluss 1938).
After the Anschluss, Seidl quickly rose through the Reich’s security apparatus. He worked under Adolf Eichmann at the Reich Security Main Office (RSHA), participating in the organization of deportations and “resettlement” of Jews and Poles from occupied territories.
Role At Theresienstadt (1941–1943)
In October 1941, Seidl was tasked with establishing and commanding the Theresienstadt ghetto (Terezín) – a ghetto located in the Protectorate of Bohemia and Moravia (now the Czech Republic).
Theresienstadt was not only a transit camp but also a propaganda tool: the Nazis used it to try to show the world that Jews were being treated “humanely.” The reality was the complete opposite:
The ghetto was severely overcrowded (the population sometimes exceeded 50,000 in a space designed for about 7,000).
Lack of food, clean water, and medicine led to widespread disease.
Under Seidl’s command, discipline was extremely brutal: beatings, arbitrary executions, and frequent deportations to Auschwitz-Birkenau and other extermination camps.
Approximately 121,000 people passed through Theresienstadt. Tens of thousands died there from starvation, disease, and mistreatment. Tens of thousands more were deported, and most were murdered.
After Theresienstadt, Seidl also served at Bergen-Belsen, Mauthausen, and participated in Einsatzgruppe activities in Hungary, coordinating the deportation of Hungarian Jews to Auschwitz.
After The War And The Trial
When the war ended, Seidl attempted to hide in Austria but was arrested. He was brought to trial before the Austrian People’s Court (Volksgericht) in Vienna.
He was charged with:
Crimes against humanity
Treason (for collaborating with the Nazis after Austria’s annexation)
Seidl was sentenced to death. During the trial and in his final days, he begged for mercy, expressing belated remorse.
On February 4, 1947, Siegfried Seidl was executed by hanging in Vienna.
Historical Significance
Siegfried Seidl’s story is a typical example of the mechanism of “normalizing evil” within the Nazi regime: an ordinary young man, influenced by extremist ideology, gradually became a crucial cog in the machinery of destruction. From joining the Nazi Party at age 19 to commanding a major ghetto, Seidl represented the thousands of mid-level officials who turned orders from above into brutal reality.
His execution in 1947 was part of the post-war accountability efforts in Austria, though many other criminals escaped or received only light sentences.
Siegfried Seidl – from an ordinary young man to the commandant of Theresienstadt – contributed directly to the deaths of tens of thousands of innocent people. Though he begged for mercy before his hanging in 1947, the crimes he committed at the ghetto and other camps remain a dark part of the Holocaust. His story reminds us that genocidal crimes are not committed solely by those at the top, but also rely on the participation of thousands of ordinary “functionaries.”
