When American troops entered the Buchenwald concentration camp in Germany on April 11, 1945, they found unburied corpses, overcrowded barracks, and thousands of prisoners weakened by starvation, disease, and years of forced labor. Many could barely stand. The SS guards had largely fled, and armed prisoners had taken control of the site before the soldiers arrived. Survivors spoke of beatings, humiliation, theft, and murder.
Among the names they repeated was that of the camp commandant’s wife, who had lived in luxury with her family in a villa overlooking the camp. While prisoners suffered below, she enjoyed expensive furniture, servants, horses, and property stolen from detainees. Former prisoners accused her of beating and humiliating them. They also connected her to a group of tattooed prisoners whose skin had been preserved after their deaths.
Her name was Ilse Koch. Born Margarete Ilse Köhler on September 22, 1906, in Dresden, then part of the German Empire, she grew up in a strict lower-middle-class Protestant family. After completing her compulsory education, she attended a commercial school and trained as a secretary. She lived through the political violence, mass unemployment, and economic turmoil of the Weimar Republic, including hyperinflation and the Great Depression, which pushed German unemployment to nearly 30 percent and left about six million people without work.
Like many Germans, Ilse was drawn to the Nazi Party’s promises of order, strength, and national renewal. She joined the party in April 1932. Nine months later, Adolf Hitler became Germany’s chancellor. In the new Nazi state, women were expected to be loyal wives and mothers, bearers of the pure Aryan generation.
But for Ilse, politics also offered a path to power. Through Nazi social circles, she met various SS and SA officers. Among them was Karl Otto Koch, her future husband. Karl Koch was an SS officer nine years older than Ilse, with prior experience in the concentration camp system the Nazis began building in 1933.
He represented the authority, status, and privilege she aspired to. They married in 1937 at Sachsenhausen concentration camp near Berlin, where he served as commandant. Shortly afterward, the SS tasked Karl with building and commanding a new camp near the city of Weimar in central Germany. It was called Buchenwald, and in the summer of 1937, the couple moved into a large villa built for them on a hill overlooking the camp.
At Buchenwald, Ilse gave birth to three children between 1938 and 1940: Arvid, Gisela, and Gudrun, who died as an infant in 1941. World War II began on September 1, 1939, when Nazi Germany invaded Poland. As the conflict expanded, the Nazi regime arrested increasing numbers of people across occupied Europe and sent many to concentration camps, including Buchenwald. The Koch family learned how much wealth could be stripped from prisoners.
Watches, jewelry, money, and other property were stolen while the family lived comfortably with servants, horses, and expensive furnishings. Ilse displayed her status openly, and some women in the SS settlement resented her ostentatious behavior. Her strained relationships with other SS officers’ wives were also attributed to her multiple sexual relationships with SS officers, including the camp’s deputy commandant, Hermann Florstedt, and the camp doctor, Waldemar Hoven, both of whom were married with children. At Buchenwald, Koch became known for provocative clothing, predatory sexual behavior, and sadism.
She was alleged to order prisoners to serve her naked and to enjoy sexually humiliating them. She sexually assaulted male prisoners and forced male prisoners to rape female prisoners. Despite having three children of her own, she reportedly hated pregnant women and beat them with a whip that had razor blades embedded along its length. She also reportedly found pleasure in beating child prisoners with a smile on her face.
According to testimony from former prisoners, Ilse Koch was even crueler than her husband and many of the SS men who served at the camp. Unlike them, she held no official position and received no orders to enter the camp or mistreat prisoners. She did so of her own free will. Her fascination with tattoos gave rise to the most horrific legend associated with her name.
She was alleged to have become obsessed with collecting pieces of tattooed human skin. Prisoners with distinctive tattoos were reportedly registered, then taken to the clinic and never seen again. After liberation, tattooed skin fragments were found in the camp’s pathology department, and lampshades made from human skin were presented as evidence. Although courts later struggled to prove her direct involvement, the horror became firmly attached to her name.
Modern forensic testing confirmed that at least one of the notorious lampshades was indeed made from human skin, corroborating what survivors had claimed for decades. Ultimately, it was corruption, not the mass killing of prisoners, that led the SS to investigate the Koch family. Karl Koch used property stolen from prisoners to fund an extravagant lifestyle and private projects, including an indoor riding hall for his wife that cost more than 250,000 German marks, equivalent to roughly $2. 5 million today.
He also bought a luxury car, opened Swiss bank accounts with money extorted from prisoners, and bribed officials to overlook his actions. In 1941, the SS opened an investigation into his administration of Buchenwald. Karl Koch was arrested but released after intervention by Heinrich Himmler, the head of the SS. Despite Himmler’s intervention, Koch lost his command at Buchenwald and was sent to Majdanek, a concentration and extermination camp in occupied Poland.
Ilse remained in the SS settlement at Buchenwald for a time, but on August 24, 1943, a renewed investigation led to the couple’s arrest together. SS judge Georg Konrad Morgen handled the case and found evidence of theft, corruption, and murder. The SS did not object to the killing of prisoners as part of the camp system. It acted because Karl Koch had stolen from the organization and ordered unauthorized killings, including the murder of prisoners who had treated him for syphilis and could have exposed his condition.
He was sentenced to death for corruption and murder and executed by firing squad at Buchenwald on April 5, 1945, six days before American forces arrived at the camp. Ilse was acquitted because the SS court said there was insufficient evidence against her. After about sixteen months in detention, she was released and moved with her surviving children to Ludwigsburg, a city in southwestern Germany where family members lived. After Germany’s surrender in May 1945, her freedom did not last long.
A former Buchenwald prisoner recognized her, and American occupation authorities arrested her on June 30, 1945. She remained in custody for nearly two years before her first postwar trial began on April 11, 1947, exactly two years after Buchenwald’s liberation. The proceedings took place at the former Dachau concentration camp near Munich, which American authorities were using for war crimes trials. There were 31 defendants, and Ilse Koch was the only woman among them.
The court found that she not only knew about prisoner abuses and killings but also participated in mistreating them. William Denson, the chief prosecutor during the trial, called her a sadistic pervert of enormous dimensions unmatched in history. The American press popularized the name by which she became widely known in English: the Witch of Buchenwald. On August 14, 1947, she was sentenced to life imprisonment.
At the time, Ilse Koch was pregnant by a fellow German war criminal detainee, though the identity of the child’s father was never determined. Her pregnancy may have influenced the court’s decision not to impose the death penalty, although this was never officially stated as the reason. Her son, Uwe, was born in Landsberg Prison in October 1947 and placed under the care of Bavarian child welfare authorities. On June 8, 1948, General Lucius D.
Clay, the American military governor of the U. S. occupation zone in Germany, reduced her sentence from life imprisonment to four years. The military review found no convincing evidence that she had selected prisoners for death because of their tattoos or that she had owned objects made from human skin.
Clay argued that the original sentence was therefore too harsh for the crimes proven at the American trial. The decision remained secret until September, but once it became public, the outcry in the United States prompted authorities to refer the case to German courts. Ilse Koch left prison on October 17, 1949, but was arrested again the same day by West German authorities. Her second postwar trial began on November 27, 1950, in Augsburg, Bavaria, and lasted seven weeks.
The court heard from about 250 witnesses, including about 50 called by the defense. Ilse collapsed several times and had to be removed from the courtroom. Her lawyers argued that she was merely the commandant’s wife and held no official authority inside Buchenwald. The court rejected that defense, and on January 15, 1951, in a 111-page ruling, she was again sentenced to life imprisonment.
She was transferred to the women’s prison in Aichach, Bavaria, where she spent the next sixteen years. Her repeated requests for clemency were denied. In her letters, she continued to claim that witnesses had lied and that others had created her reputation. Her mental health slowly deteriorated.
Prison staff described her as unstable and increasingly paranoid, as she claimed that former concentration camp prisoners were entering her cell and attacking her. The final part of Ilse Koch’s life was closely tied to the son she never raised. Uwe grew up in Bavarian care homes. As a child, he saw his mother’s name on his birth certificate and remembered it.
When he turned nineteen, he read a newspaper article about her and realized who she was. Uwe visited Ilse in Aichach Prison during the Christmas season of 1966 and thereafter came once a month, the maximum the prison allowed. Uwe later described their meeting as happy. Outside the prison, however, the consequences of Ilse Koch’s past continued to shape her family’s life.
Her children lived under the weight of her name, and her eldest son, Uwe, isolated and ashamed of his parents, took his own life in 1967. Shortly afterward, Ilse’s mental condition deteriorated further. On September 1, 1967, three weeks before her sixty-first birthday, Ilse Koch hanged herself in her cell. She left a note for Uwe that read: “I cannot help myself.
For me, death is redemption. ” She was buried in an unmarked grave in Aichach cemetery.
