On the morning of April 11, 1945, American soldiers from the Fourth and Sixth Armored Divisions entered the Buchenwald concentration camp in Nazi Germany. What they found was a landscape of horror, with piles of corpses and living prisoners barely distinguishable from the dead. Some soldiers wept, while others could not speak.
In the officer’s quarters, investigators discovered objects beyond belief. They found examples of tattooed human skin, shrunken human heads, and a table displaying human remains like samples. The Americans later ordered citizens from the nearby city of Weimar to witness what had been done in their name.
Among the survivors, one name was spoken again and again. It belonged to the woman who lived in the villa above the camp and ruled with cruelty and vanity. She became known as the Bitch of Buchenwald, but her real name was Ilse Koch.
Ilse Koch was born as Margarete Ilse Köhler on September 22, 1906, in Dresden, then part of the German Empire. Her father was a master craftsman and her mother cared for the household. After completing her schooling, she trained as a secretary and found work in several local firms.
As a young woman in the 1920s, Ilse lived through the chaos of the Weimar Republic. Hyperinflation, unemployment, and street battles between political extremes shaped her generation. For many, the promises of strong leadership and national rebirth offered by the rising Nazi party seemed to answer the despair of those years.
In April 1932, Ilse joined the Nazi party. She was 25 years old, ambitious, and drawn to the energy and spectacle of Nazism. Less than a year later, Adolf Hitler came into power.
In the new Nazi Germany, women were expected to serve as loyal wives and mothers. But for Ilse, politics was also a path to power. Through Nazi social circles, she met various officers of the SS and SA, including a man named Karl Otto Koch.
Karl Koch was an SS officer, disciplined and proud, with experience in the growing system of concentration camps. He was nine years older than Ilse and represented everything she admired. Their relationship grew quickly, and they married in 1937 at the Sachsenhausen concentration camp, where Karl had been appointed commandant.

It was a strange wedding, held inside a place of terror surrounded by guards and prisoners. Soon afterward, the SS assigned Karl Koch to build and command a new camp near the city of Weimar. The place was called Buchenwald.
In the summer of 1937, the couple moved into a large villa built for them on a hill overlooking the camp. Two years later, the Second World War began. Between 1938 and 1940, Ilse gave birth at Buchenwald to three children. The youngest, Gudrun, died of pneumonia in February 1941 at the age of four months.
On the surface, Ilse appeared to be the perfect SS wife. She was elegant, educated, and devoted to her husband and to the ideals of Adolf Hitler. But beneath the surface, greed and cruelty took hold.
The Kochs quickly discovered how profitable their position could be. They stole from prisoners everything of value, including watches, jewelry, money, and even gold teeth. Thanks to this, they lived like aristocrats with servants, horses, and fine furniture.
Ilse wore expensive dresses and paraded her wealth. She enjoyed humiliating anyone beneath her. To other SS wives, she was boastful and vulgar, showing off her new wealth and exploiting her position as the wife of the feared camp commander.
Her relationships with other SS wives were also damaged by her sexual affairs with other men in the camp. These included the camp’s deputy commandant and a physician, both of whom were married with children.
Just as she flirted with SS men, she was brutal toward prisoners. She rode through the camp on horseback, striking prisoners with a whip and shouting insults. She was remembered for laughing during executions. She allegedly walked near camp barracks in revealing clothing, and men who looked at her were beaten half to death or shot in the head.
At Buchenwald, Ilse Koch became known for predatory sexual behavior and sadism. She ordered prisoners to serve her while she was nude and enjoyed sexually humiliating inmates. She also sexually abused prisoners and forced male inmates to rape female prisoners in front of her.

Despite having two children of her own, she hated pregnant women. She used to beat them with a whip along which pieces of razor were inserted. She also found pleasure in beating child inmates, conducting these acts with a smile on her face.
Her fascination with tattoos gave rise to the most terrible legend of all. She allegedly became obsessed with collecting pieces of tattooed human skin. Inmates with distinctive tattoo designs were noted by number, taken to the infirmary, and never returned.
After the liberation, pieces of tattooed skin were found in the camp’s pathology department. Lampshades made from human hides were displayed as evidence. Although courts later struggled to prove her direct involvement, the horror became inseparable from her name. Modern forensic tests confirmed that at least one of the infamous lampshades was indeed made from human skin.
Beneath the brutality, greed also corrupted the Koch household. In 1940, Karl Koch built an indoor riding arena for his wife that cost more than 250,000 Reichsmarks, a fortune stolen from prisoner property. He also bought a luxury car and opened Swiss bank accounts with money extorted from prisoners.
In 1941, their crimes attracted attention, and an investigation began into Karl Koch’s governance of Buchenwald. He was arrested but soon freed after SS chief Heinrich Himmler intervened. Karl was nonetheless relieved of his duties at Buchenwald and sent to command the Majdanek concentration and extermination camp in occupied Poland.
Ilse Koch continued to live in the SS settlement at Buchenwald in her husband’s absence. However, on August 24, 1943, both Karl and Ilse were arrested following a renewed SS investigation. The case was assigned to SS Judge Konrad Morgen, who found evidence of theft, corruption, and murder.
In the eyes of the SS, the crime was not the death of the prisoners itself, but the fact that Koch had ordered killings without authorization. He had also killed prisoners who treated him for syphilis, fearing they might expose him. The trial that followed was extraordinary, as the SS was judging its own.
Karl Otto Koch was sentenced to death for disgracing himself and the SS. He was executed by firing squad on April 5, 1945. Following the trial, Ilse was released after 16 months in prison and moved with her two children into a small flat in the city of Ludwigsburg.

When Nazi Germany collapsed, the Allied forces began to uncover the full scale of Nazi crimes. Buchenwald was liberated on April 11, 1945. On June 30 of that year, Ilse Koch was arrested by American occupation authorities after being recognized on the street by a former inmate of the camp.
Ilse was held in prison for two years before her trial opened on April 11, 1947, at the former Dachau concentration camp near Munich. Out of 31 defendants, she was the only woman. The court considered her knowledge and at least indirect involvement in the exploitation and murder of inmates to be proven.
The chief prosecutor during the trial said she was nothing less than a sadistic pervert of monumental proportions, unmatched in history. In August 1947, Ilse Koch was sentenced to life imprisonment for crimes against humanity. She was in an advanced stage of pregnancy at the time, which is said to have saved her from the death penalty imposed on 22 of her 30 co-defendants.
A year later, in December 1948, General Lucius D. Clay, military governor of the US occupation zone in Germany, commuted her sentence to four years because of insufficient evidence. The decision caused outrage in the United States. Under public pressure, the case was handed to the German courts.
The hearing of the second trial opened on November 27, 1950, and lasted seven weeks. During that time, 250 witnesses were heard, including 50 for the defense. Ilse collapsed and had to be carried from court in late December 1950 and again in January 1951.
The defense claimed that she was merely the wife of a commandant who had no authority in the camp. The court was not persuaded. On January 15, 1951, in a 111-page verdict, Ilse Koch was sentenced to life imprisonment. She was the only woman in West Germany to receive such a sentence for Nazi crimes.
She was transferred to the women’s prison in Aichach in Bavaria. There she spent the next 16 years behind bars. Her petitions for pardon were rejected one after another. In letters, she insisted she had been falsely accused and that her reputation had been destroyed by lies.
Her mental state deteriorated. Guards described her as unstable, paranoid, and haunted by visions. When she was in prison, the world remembered her not for what she denied, but for what she represented: the moral collapse of those who embraced absolute power.
Ilse Koch became the image of the female face of the Nazi regime. She was proof that evil is not confined to men or monsters, but can dwell behind the face of an ordinary woman who chose to abandon conscience for a life of privilege and luxury.
Outside the prison, her children lived under the shadow of her name. Her son Artwin, isolated and ashamed of his parents, committed suicide in 1967. Soon after the death of her son, Ilse lost contact with reality. On September 1, 1967, she hanged herself. She was buried in an unmarked grave.
The Bitch of Buchenwald was dead. She was 60 years old.
