Final Reckoning of the “Hyena of Auschwitz”: The Execution of Irma Grese, the Most Feared Nazi Guard
Among the countless perpetrators of the Holocaust, most were men. But there was one woman whose name became synonymous with cruelty, sadism, and the absolute corruption of power: Irma Grese. She was not a commandant. She was not a doctor. She was a guard – barely out of her teens – yet survivors spoke of her with more terror than many of the male SS officers. At 22 years old, she stood before a British military tribunal in 1945, convicted of war crimes and crimes against humanity. On December 13, 1945, Irma Grese was led to the gallows at Hamelin Prison. She was the youngest woman executed under British law in the 20th century.
This is the story of how a young German woman became the “Hyena of Auschwitz” – and her final reckoning with justice.
1. The Making of a Monster: From Farm Girl to SS Guard
Irma Grese was born on October 7, 1923, in the small town of Wrechen, Germany. She was the third of five daughters born to Alfred Grese, a devout Christian who worked as a dairy worker, and Berta Grese, who died by suicide when Irma was just 12 years old. Her father was an opponent of the Nazi Party, but Irma, like many German youth of her generation, was drawn to the Hitler Youth movement – specifically the female branch, the League of German Girls (BDM). She left school at 15, worked briefly as a nursing assistant, then as an assistant on a dairy farm, but was dissatisfied.
In 1942, at the age of 19, Irma Grese volunteered for service with the SS. Her motive was not political ideology alone – she was also seeking escape from her rural life and a position of power. She was sent to Ravensbrück, the main training camp for female SS guards. There, she was trained in the brutal techniques of terror, surveillance, and the dehumanization of prisoners.
Ravensbrück was a place where new guards learned to suppress any remnant of empathy. They witnessed medical experiments, beatings, and starvation. They were taught that prisoners were not human beings but Untermenschen (subhumans) – vermin to be exterminated. Grese excelled. Her superiors noted her “enthusiasm” and “ruthlessness.” Within months, she was promoted and transferred to the largest death camp in history: Auschwitz-Birkenau.
2. The Hyena of Auschwitz: Terror in the Women’s Camp
Irma Grese arrived at Auschwitz-Birkenau in March 1943. She was assigned to the women’s camp (the so-called “Birkenau women’s camp” or “C-Lager”), where tens of thousands of Jewish, Roma, and political prisoners were imprisoned in conditions of unimaginable horror. Grese quickly rose through the ranks, becoming the youngest woman to hold the rank of Oberaufseherin (Senior Supervisor) – second only to the camp commandant.

From the moment she arrived, Grese earned a reputation for cruelty that rivaled the most brutal SS doctors and guards.
Survivors later testified that Grese:
Carried a whip and used it constantly. She would beat prisoners mercilessly, often across the face and breasts, for no reason other than her own amusement. The whip became her signature weapon.
Set her trained dogs on prisoners. She walked the camp with two large, ferocious dogs. If a prisoner moved too slowly or did not bow quickly enough, Grese would release the dogs to tear into their flesh.
Participated in selections for the gas chambers. Alongside Dr. Josef Mengele and other SS doctors, Grese would stand on the Rampa (loading ramp) and decide which prisoners were fit for work – and which would be sent immediately to the gas chambers. Survivors recalled her pointing a manicured finger to the left – toward death – with a cold, unfeeling expression.
Tormented pregnant women, children, and the sick. According to testimony, Grese took particular pleasure in tormenting those most vulnerable. She was known to beat pregnant women until they miscarried, and to throw starving children against walls or onto electrified fences.
One survivor, Olga Lengyel, wrote in her memoir about watching Grese personally beat a prisoner to death. Another survivor, Gisella Perl, a Jewish doctor who was forced to work in the camp hospital, testified that Grese would rip babies from their mothers’ arms and smash their heads against the sides of cattle cars.
For these acts, she earned dozens of nicknames from the prisoners – but the most enduring was “The Hyena of Auschwitz.”
A hyena is an animal known for laughing while it kills. Survivors said that Grese often smiled or laughed as she tortured prisoners. Her beauty – blonde hair, blue eyes, a youthful face – made her cruelty even more grotesque. She was often called “The Beautiful Beast.”
3. From Auschwitz to Bergen-Belsen: The Final Days of the Reich
As the Soviet Red Army advanced toward Poland in late 1944, the SS began evacuating Auschwitz. Grese was assigned to accompany prisoners on the infamous “death marches” – forced evacuations in which tens of thousands of prisoners died of exposure, starvation, or were shot by the side of the road. Grese continued her brutality during the marches, shooting prisoners who collapsed or lagged behind.
She was then transferred to Bergen-Belsen concentration camp in northern Germany, where conditions were even worse than Auschwitz. By 1945, Bergen-Belsen had become a place of utter catastrophe – overcrowded, without food, water, or medicine. Tens of thousands of prisoners died of typhus, starvation, and dysentery in the final months of the war.
Grese did not relent. Survivors testified that she continued to beat prisoners and set her dogs on the sick and dying. One British soldier who later entered the camp described the scene as “the most horrific place on earth” – corpses stacked like cordwood, skeletal figures barely alive, and the stench of death everywhere.
On April 15, 1945, British forces liberated Bergen-Belsen. Among the piles of dead and the barely alive, they found Irma Grese. She was arrested along with other SS personnel – including Josef Kramer, the commandant of Bergen-Belsen (known as the “Beast of Belsen”), and other female guards such as Elisabeth Volkenrath and Juana Bormann.
4. The Belsen Trial: Justice in the Rubble
Irma Grese was among 45 defendants tried at the Belsen Trial (officially known as Trial of Josef Kramer and 44 Others), held at the Gymnasium in Lüneburg, Germany, from September 17 to November 17, 1945. It was one of the first major war crimes trials of the post-war era, conducted by a British military tribunal.
The prosecution called over 200 witnesses – many of them survivors of Auschwitz and Bergen-Belsen. Their testimonies painted a horrifying picture of Grese’s cruelty.
Key testimony against Grese:
Survivors described her “childlike pleasure” in watching prisoners suffer.
She had been seen tearing live babies from their mothers and throwing them into the air, shooting them, or smashing their heads against walls.
She personally selected thousands of prisoners for the gas chambers.
She beat prisoners to death with her whip and set her dogs on dying inmates.
Grese’s defense was simple: she denied everything. She claimed she was only following orders, that her role was merely to maintain order in the camps, and that she never personally killed anyone. She argued that prisoners exaggerated her actions out of hatred and that photographs of abused prisoners were not caused by her.
The court was not persuaded. The evidence was overwhelming. Witness after witness testified to her sadism, her delight in suffering, and her direct role in the murder of thousands.
On November 17, 1945, the tribunal delivered its verdict. Irma Grese was found guilty of war crimes and crimes against humanity. She was sentenced to death by hanging. She was 22 years old.
5. The Final Hours: Execution at Hamelin Prison
After the trial, Grese was transferred to Hamelin Prison in Lower Saxony, Germany. She spent her final weeks in a cold cell, awaiting execution. According to prison guards and chaplains who spoke with her, she remained defiant. She expressed no remorse for her actions. She insisted that she had done nothing wrong – that she was simply serving her country during a time of war, and that she was being punished for doing her duty.
On the morning of December 13, 1945, Irma Grese was led to the gallows in Hamelin Prison’s execution chamber. She was 22 years old.
She walked to the gallows without a blindfold. Some reports claim she stared directly at the British witnesses with cold, unblinking eyes. Others say she looked tired, resigned, but still unrepentant. The trapdoor opened. She fell. She was pronounced dead moments later.
She was one of three female SS guards executed that same morning. The others were Elisabeth Volkenrath and Juana Bormann.
Grese was buried in an unmarked grave in the prison cemetery – a final act of erasure from history.
6. Why Her Story Still Haunts Us
The story of Irma Grese disturbs us for several reasons.
First, her youth. She was only 19 when she became an SS guard, 22 when she was hanged. It forces us to confront the reality that evil does not require age or experience. A young woman, barely out of her teens, willingly transformed herself into a sadistic killer.
Second, her beauty. Survivors and soldiers alike commented on her striking appearance – blonde hair, blue eyes, a pretty face. The juxtaposition of her physical beauty with her moral ugliness has made her a figure of enduring fascination. But her beauty was also a weapon. Prisoners said her smile was more terrifying than her whip.
Third, her ordinariness. By all accounts, Irma Grese came from a normal, working-class family. Her father opposed Nazism. She was not a fanatical ideologue from birth. But she absorbed the ideology of a regime that taught her that some human beings were “subhuman” and that violence was a virtue. She chose power. She chose cruelty. She chose to become a monster.
Fourth, her lack of remorse. To the very end, Irma Grese believed she was innocent. She did not weep. She did not apologize. She did not ask forgiveness from the families of her victims. She died as she lived – cold, defiant, and unrepentant.
The Hyena’s End

Irma Grese was not the highest-ranking Nazi tried after the war. She was not a commandant, not a doctor, not a policymaker. But in the memories of survivors, she looms as large as any of them. Because she was the face of everyday evil – the person who looked at children being led to the gas chambers and smiled, who beat pregnant women for fun, who laughed while she tortured.
Her execution on December 13, 1945, did not bring back the thousands she helped to murder. It did not heal the wounds of survivors or erase the memories of those who suffered under her whip. But it was a reckoning – a small measure of justice in a world that had seen far too much injustice.
She was buried in an unmarked grave. No headstone marks where the Hyena of Auschwitz lies. But her name lives on – not as a figure of admiration, but as a warning: that without conscience, without empathy, without the courage to resist evil, even a young woman with a pretty face can become a monster.
