On April 11, 1945, soldiers of the United States Army entered the Buchenwald concentration camp in Germany. Most of the SS guards had fled, and armed prisoners had taken control of the grounds. Among the wooden barracks, the Americans found unburied corpses, overcrowded huts, and thousands of prisoners weakened by hunger, disease, and years of forced labor. Many could barely stand.
Survivors spoke of beatings, humiliation, robbery, and murder. Among the names they repeated was that of the camp commandant’s wife, who had lived with her family in comfort in a villa overlooking the camp. While prisoners suffered below, she enjoyed expensive furniture, servants, horses, and property stolen from the detainees. Former prisoners accused her of beating and insulting them.
They also linked her name to a group of tattooed inmates whose skin had been preserved after death. Her name was Ilse Koch. She was born Margarete Ilse Köhler on September 22, 1906, in Dresden, then part of the German Empire. Her father, Max, was a skilled craftsman, and her mother, Anna, managed the household.
Ilse grew up in a strict Protestant lower-middle-class family. After completing compulsory education, she attended a business school where she learned secretarial skills, then found work as a clerk and secretary for several local companies. She spent her early adult years during the Weimar Republic, the democratic German state established after Germany’s defeat in World War I. She witnessed political violence, mass unemployment, and the economic troubles that followed the hyperinflation of the early 1920s and the Great Depression, which pushed unemployment in Germany to nearly thirty percent, leaving around six million people across the country 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 and received membership number 1,130,836. Nine months later, in January 1933, Adolf Hitler became Chancellor of Germany. In the new Nazi state, women were expected to be loyal wives and mothers, bearers of the pure Aryan generation.
For Ilse, however, politics was also a path to power. She was fascinated by the Nazi Party, and through its social circles she met various SS and SA officers, paramilitary Nazi organizations. Among them was a man whose fate would soon be tied to hers, Karl Otto Koch, her future husband. Karl Koch was an SS officer nine years older than Ilse who already had experience in the concentration camp system the Nazis had begun building in 1933.
For her, he represented the authority, status, and privileges she aspired to. They married in 1937 at the Sachsenhausen concentration camp near Berlin, where he served as commandant. Shortly afterward, the SS assigned Karl to build and lead a new camp near the city of Weimar in central Germany. The place 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 quickly learned how much wealth could be stripped from concentration camp prisoners.
Watches, jewelry, money, and other possessions were stolen while the family lived in luxury with servants, horses, and expensive furniture. Ilse displayed her status openly, and some women in the SS settlement resented her for her ostentation and display of new wealth. Her strained relations with other SS officers’ wives were also attributed to her numerous sexual relationships with SS officers, including the camp’s deputy commandant Hermann Florstedt and the physician Waldemar Hoven, both married with children. At Buchenwald, Koch became known for wearing provocative clothing and gained a reputation for predatory sexual behavior and sadism.
She was alleged to have ordered prisoners to serve her while naked and to have enjoyed sexually humiliating them. She also sexually assaulted male prisoners and forced them to rape female prisoners in front of her. Despite having three children, she hated pregnant women and used to beat them with a whip that had razor blade fragments inserted along its entire length. She also took pleasure in beating child prisoners, doing so with a smile on her face.
According to testimonies 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 horrifying legend of all.
She was alleged to have become obsessed with collecting pieces of tattooed human skin. Prisoners with distinctive tattoos were said to be recorded by number, taken to the clinic, and never seen again. After liberation, pieces of tattooed skin were found in the camp’s pathology department, and lampshades made from human skin were displayed as evidence. Although courts later struggled to prove her direct involvement, this horror became permanently attached to her name.
Modern forensic tests confirmed that at least one of the infamous lampshades was indeed made from human skin, proving what survivors had claimed for decades. In the end, it was corruption, not the mass killing of prisoners, that caused 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 over 250,000 Reichsmarks, equivalent to roughly 2. 5 million US dollars 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 began investigating his administration of Buchenwald. Karl Koch was arrested but released after the intervention of Heinrich Himmler, 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. The case was handled by SS judge Georg Konrad Morgen, who 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 troops 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 her family members lived. Her freedom did not last long after Germany’s surrender in May 1945.
A former Buchenwald prisoner recognized her, and American occupation authorities arrested her on June 30, 1945. She remained in detention 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 in southern Germany, which American authorities were then using for war crimes trials. There were thirty-one defendants, and Ilse Koch was the only woman among them.
The court found that she not only knew of prisoner abuses and killings but also participated in their mistreatment. William Denson, the chief prosecutor during the trial, said she was nothing but a sadistic pervert of enormous dimensions, unmatched in history. The American press popularized the name by which she became widely known in English, the Bitch of Buchenwald. On August 14, 1947, she was sentenced to life imprisonment.
Ilse Koch was pregnant at the time, the father being a fellow inmate among the German war criminals, although the identity of the child’s father was never determined. Her pregnancy may have influenced the court’s decision not to sentence her to death, though this was never officially stated as a 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 US occupation zone in Germany, commuted her sentence from life imprisonment to four years. The military review found no convincing evidence that she had chosen 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, widespread outrage in the United States led 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 the city of Augsburg in Bavaria and lasted seven weeks. The court heard about 250 witnesses, including about fifty 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 this defense, and on January 15, 1951, in a 111-page ruling, sentenced her once again to life imprisonment. She was transferred to the women’s prison in Aichach, Bavaria, in southern Germany, 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, with prison staff describing her as unstable and increasingly paranoid, claiming that former concentration camp prisoners entered her cell and attacked her. The last part of Ilse Koch’s life was closely tied to the son she never raised. Uwe Köhler grew up in Bavarian care homes.
As a child, he saw his mother’s name on his birth certificate and remembered it. When Uwe was nineteen, he read a newspaper article about her and realized who she was. He visited Ilse in Aichach prison during the Christmas season of 1966, and from then on came once a month, the maximum the prison allowed. Uwe later described their meetings as happy.
Outside 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, leaving a letter for Uwe that read: “I cannot help myself.
For me, death is salvation. ” She was buried in an unmarked grave in the Aichach cemetery.
