The Ilse Koch trial was actually two trials. An American military tribunal at Dachau convicted her in 1947 and sentenced her to life imprisonment, which General Lucius D. Clay commuted to four years. After her 1949 release, West German prosecutors immediately rearrested her, tried her in Augsburg for crimes against German nationals, and in 1951 sentenced her to life at hard labor. She died by suicide in a Bavarian prison on September 2, 1967, after every appeal failed.1Yad Vashem. Koch, Karl and Ilse
Why She Was Prosecuted Without Holding Any Rank
Ilse Koch was the wife of SS Colonel Karl Otto Koch, who commanded Buchenwald from its founding in 1937 until 1941. She held no official rank and no administrative role. She lived on the camp grounds and moved freely among the prisoner population, and survivors testified that she used that access to provoke inmates and watch the punishments that followed.
Her lack of rank became the central legal question at Dachau. The prosecution had to show that a civilian without command authority could still be held liable for what happened inside a concentration camp. Her husband’s fate hinted at how visible the couple’s conduct had been: the SS itself had investigated Karl Koch for embezzlement and the unauthorized killing of three prisoners, and he was executed by firing squad on April 5, 1945, days before American forces reached the camp.2United States Holocaust Memorial Museum.

The 1947 Dachau Tribunal
American authorities used the site of the former Dachau concentration camp as the central location for hundreds of war crimes trials of lower-ranking defendants who fell outside the major Nuremberg proceedings. The tribunals operated under Joint Chiefs of Staff Directive 1023/10, issued July 8, 1945.3National Archives. War Crimes Trials in Europe 1945-1948
They used a “common design” theory of liability. Prosecutors did not have to prove that a defendant personally killed anyone. They had to prove that the defendant voluntarily participated in running a concentration camp whose entire operation was criminal. That theory reached guards, administrators, medical staff, and civilian associates alike.
On March 4, 1947, the tribunal charged 31 defendants connected to Buchenwald: 28 former camp personnel, two former kapos, and one former prisoner. The trial opened on April 11, 1947. Koch was the only civilian woman among the defendants and drew the heaviest press coverage. She was pregnant during the proceedings.
She was charged with participating in the common design to commit violations of the laws and customs of war, specifically with encouraging, aiding, and participating in the killing, torture, and mistreatment of prisoners.4United States Holocaust Memorial Museum.

The Human Skin Allegations
The most sensational charges claimed Koch selected prisoners with distinctive tattoos, had them killed, and had their skin turned into household objects such as lampshades and book covers. Multiple survivors testified that she rode through the camp on horseback picking out tattoos she wanted, and witnesses described finished items in the Koch residence. Prosecutors presented physical exhibits recovered from the camp’s pathology department, including preserved skin and shrunken heads.
Defense counsel argued the items came from legitimate anatomical collections and could not be tied specifically to Koch. Eyewitness testimony was vivid but sometimes contradictory, and the chain of custody for the physical exhibits was difficult to establish. Linking the objects to Koch’s individual orders proved harder than establishing that the objects existed.
Verdict
The tribunal convicted Koch on August 14, 1947, and sentenced her to life imprisonment.4United States Holocaust Memorial Museum. Ilse Koch Is Sentenced to Life in Prison at the Trial of Former Camp Personnel and Prisoners From Buchenwald
The Commutation and the Senate Investigation
General Lucius D. Clay, the military governor of the American occupation zone, reviewed the case. His deputy judge advocate concluded that while the finding of guilt under the common-design theory was justified, the evidence of Koch’s individual participation did not warrant a life sentence. The review found “no convincing evidence that she selected inmates for extermination in order to secure tattooed skin or that she possessed any articles made of human skin.” The War Crimes Board of Review, the judge advocate, and multiple senior staff officers concurred. Clay commuted the sentence to four years, backdated to October 18, 1945.
The public reaction in the United States was severe. A Senate subcommittee opened an investigation. Its report stopped short of accusing the reviewing officers of bad faith but concluded that the evidence against Koch had been “inadequately presented in her trial and in the various stages of the review of the trial record.” The senators cited testimony that Koch had personally struck prisoners, instigated beatings, and watched brutalities with apparent enjoyment, and referred to what they called “hearsay evidence of an unusually reliable sort” concerning the skin articles. The subcommittee recommended either a new U.S. military trial for offenses not covered originally or, failing that, prosecution by German courts for crimes against German nationals.
The West German Trial in Augsburg
Koch finished her four-year American sentence and was released in October 1949. German authorities arrested her the same day. The American tribunal had jurisdiction only over crimes against Allied nationals and non-German prisoners, leaving offenses against German citizens unaddressed. That jurisdictional gap opened the door to a second prosecution.
The Augsburg trial convened in 1950 under German domestic criminal law. Prosecutors called witnesses who had not appeared at Dachau and built their case around Koch’s treatment of German inmates. The charges were more specific than the broad common-design theory. On January 15, 1951, the court convicted Koch on one count of inciting murder, one count of inciting attempted murder, five counts of inciting severe physical mistreatment of prisoners, and two counts of direct physical mistreatment. She was sentenced to life imprisonment at hard labor with the permanent withdrawal of her civil rights.1Yad Vashem. Koch, Karl and Ilse
The second prosecution did not violate double jeopardy principles. The victims were different (German nationals rather than Allied prisoners), the legal codes were different (German criminal statutes rather than international military law), and the sovereign was different (the West German government rather than the U.S. military).
Prison, Appeals, and Death
Koch was held at the women’s prison in Aichach, Bavaria. She filed multiple appeals; each was rejected. The West German Supreme Court upheld the life sentence and closed her final legal avenue. She maintained her innocence throughout and submitted petitions for clemency that were denied. On September 2, 1967, she died by suicide in her cell at age 60.1Yad Vashem. Koch, Karl and Ilse
The Lampshade Evidence, Decades Later
The evidentiary question at the heart of the 1947 commutation kept resurfacing. A small lampshade recovered from Buchenwald went on display at the camp’s memorial museum in 1954, labeled as human skin, without scientific verification. It remained unexamined for nearly four decades.5Buchenwald Memorial. Small Lampshade
In 1992, the Institute of Forensic Medicine at the Erfurt Medical Academy examined the object and concluded it “cannot be serologically identified as human,” suggesting it might be synthetic while not ruling out biological origin. That finding appeared to support Clay’s 1948 conclusion.
In 2023, a new examination using microscopic and genetic analysis concluded the material was “certainly human skin.”5Buchenwald Memorial. Small Lampshade Whether this particular lampshade was ever connected to Koch’s personal orders or to the camp’s broader pathology operations remains an open question. The material itself is no longer one.
