The woman who walked through the gates of Auschwitz-Birkenau as the highest-ranking female SS officer in the camp system met her end on a cold January morning in 1948, hanged at Montelupich prison in Krakow just 36 years after her birth in a quiet Austrian farming village.

The execution of Maria Mandel, known to survivors as “The Beast,” came with startling speed after a trial that lasted barely a month. The Supreme National Tribunal of Poland delivered its verdict on December 22nd, 1947, and within weeks, the sentence was carried out. There were no lengthy appeals, no international campaigns for clemency, no last-minute reprieves.

The court had reviewed the evidence, heard the testimony of survivors who had watched her point a finger at women and children destined for the gas chambers, and concluded that the scale of her crimes demanded the ultimate penalty.

Born on January 10th, 1912, in Münzkirchen, Upper Austria, Mandel grew up in a world shattered by the collapse of the Austro-Hungarian Empire. Her father was a shoemaker, the family Catholic and working class, living a simple rural existence that gave no hint of the brutality she would later command. She attended local schools, trained as a seamstress, and by all accounts lived an unremarkable life through the turbulent 1920s, when Austria faced hyperinflation and political violence between right-wing and left-wing factions.

The Great Depression hit Austria with devastating force, pushing unemployment to nearly 26% by 1932. Young people across the country looked for stability, for something bigger than the struggle for survival. When Adolf Hitler became Chancellor of Germany in 1933, his message of national pride and order resonated beyond Germany’s borders.

Austrian Nazis pushed aggressively for union with Germany, and on March 12th, 1938, German troops marched into Austria in what became known as the Anschluss.

Mandel was 26 years old when Austria was absorbed into the Third Reich. Shortly after the annexation, she joined the Nazi Party and applied for work connected to the SS system. This was not unusual.

Thousands of Austrians joined Nazi organizations after 1938, seeing opportunities for career advancement that had never existed before. For a seamstress from a struggling village, the SS offered uniforms, structured authority, and regular pay. It was a step up in status that she seized without hesitation.

When Germany invaded Poland on September 1st, 1939, and Britain and France declared war two days later, the Nazi camp system began expanding at a pace that required massive recruitment. Mandel entered service at Ravensbrück Concentration Camp, located about 90 kilometers north of Berlin. Ravensbrück had opened in May 1939 as the main concentration camp for women in Nazi Germany and quickly became the central training ground for female SS guards, known as Aufseherinnen.

By the end of 1940, Ravensbrück held more than 4,000 women. German political opponents arrived first, followed by Polish women arrested after the invasion, French resistance members, Dutch political prisoners, Soviet women captured after 1941, Jewish women from across Europe, Roma women, and Jehovah’s Witnesses who refused to pledge loyalty to Hitler. The camp became a multinational prison of fear, with overcrowded barracks, minimal food rations, and typhus outbreaks that swept through the starving population.

Mandel entered Ravensbrück as a basic female guard, responsible for supervising prisoner labor and maintaining order. Female guards were trained to show strict discipline, taught that prisoners were enemies of the state. Violence was normalized.

Beatings were allowed. Punishments included standing for hours, denial of food, or confinement. Mandel quickly stood out to her superiors, described in later testimonies as efficient and firm, someone who did not hesitate to enforce rules and followed orders closely.

Within about a year, she was promoted to Rapportführerin, a position that gave her responsibility over roll calls and internal discipline. Roll calls could last several hours in freezing weather, especially during winter. Prisoners had to stand still and be silent while numbers were checked.

If the counts didn’t match, the entire group remained outside until the mistake was corrected. Women who collapsed from exhaustion were often beaten. Some died where they stood.

During this period, Ravensbrück also became the site of medical experiments. Between 1942 and 1943, doctors deliberately infected wounds with bacteria like streptococcus and gangrene to test new drugs. In some cases, bone and muscle were removed to study regeneration.

Many women were left permanently disabled. Some died from infections. Mandel was not listed as a medical researcher, but she was part of the camp leadership structure that maintained control over the prisoners selected for these procedures.

In October 1942, Mandel was transferred to Auschwitz II, Birkenau, the largest section of the Auschwitz camp system in occupied Poland. The Auschwitz complex had been set up in 1940 near the town of Oświęcim, initially holding mainly Polish political prisoners. After the Wannsee Conference in January 1942, where senior Nazi officials coordinated what they called the final solution to the Jewish question, Birkenau became the main killing center inside the Auschwitz system.

When Mandel arrived, Birkenau was expanding rapidly. New barracks were being built. Gas chambers and crematoria were operating.

Trains were arriving from across Europe carrying Jews from France, the Netherlands, Belgium, Slovakia, and later Greece and Italy. Many had no idea where they were going, believing they were being resettled. Mandel was appointed chief female guard of the women’s camp at Birkenau, placing her in charge of hundreds of female SS guards and thousands of female prisoners.

She was not just supervising labor details anymore. She was running daily life for the entire women’s section, controlling discipline, punishments, work assignments, and selections. The numbers were staggering.

Over the entire period of Auschwitz’s operation, more than 130,000 women were deported there. About 90,000 of them died. Some were killed in gas chambers immediately.

Others died from starvation, disease, beatings, medical experiments, or exhaustion.

In 1944, when deportations from Hungary reached their peak, the women’s camp held over 30,000 prisoners at one time. Mandel controlled this environment. She approved punishments.

She oversaw selections. Selections were the heart of the killing process. When new trains arrived, SS doctors stood near the railway ramp.

Prisoners were ordered off the cattle cars and forced into lines. A quick look determined their fate. Those judged strong enough for labor were sent into the camp.

The elderly, the sick, most mothers with small children, and many children were sent directly to the gas chambers.

Survivors later testified that Mandel walked through the women’s barracks and pointed at prisoners she considered too weak to work. Women and children she selected were loaded onto trucks or marched to the crematoria within hours. There was no long process.

By 1943, she had been promoted to Lagerführerin of the women’s camp at Birkenau, the highest position a female guard could hold there. She reported directly to the male SS leadership, including Rudolf Höss, who served as commandant of Auschwitz until November 1943.

Her authority over female prisoners was nearly absolute. Under her supervision, daily life became even harsher. Prisoners were forced into exhausting labor details.

Some worked on construction projects, expanding Birkenau’s endless rows of barracks. Others dug drainage ditches in muddy ground that never fully dried. Many sorted clothing, shoes, glasses, and personal belongings taken from Jews who had already been gassed.

These items were cleaned, packed, and shipped back to Germany.

Survivor testimonies later described her behavior during selections as especially ruthless. Children rarely survived these reviews. Mothers were often separated from daughters.

Elderly women were immediately removed. Twins were sometimes taken aside for medical experiments led by Dr. Josef Mengele, who conducted experiments on twins to study genetics, often without anesthesia, and with deadly results.

Later in 1943, Mandel ordered the creation of a women’s orchestra in Birkenau. The group became known as the Auschwitz women’s orchestra, and its role was both practical and symbolic. Music was used to regulate camp life.

The orchestra played during morning and evening roll calls. It played as work details marched through the gates, helping guards keep prisoners in step. Sometimes, it even played near the crematoria while smoke from burning bodies rose in the background.

The first conductor was Zofia Czajkowska, a Polish music teacher imprisoned in the camp. Later in 1943, Alma Rosé took over as conductor. Rosé was a Jewish violinist from Vienna and the niece of composer Gustav Mahler.

Under Rosé’s leadership, the orchestra improved. Rehearsals were strict and long. Instruments were gathered from the confiscated belongings of deported Jews.

The musicians received slightly better food rations and were housed separately from the general population. Mandel supported the orchestra and attended performances. She enjoyed music and expected the orchestra to perform well.

By mid-1944, the scale of killing at Auschwitz reached its highest point. Between May and July 1944, around 437,000 Hungarian Jews were deported to Auschwitz in a matter of weeks. Most were sent directly to the gas chambers upon arrival.

The crematoria operated almost continuously. When they couldn’t keep up, bodies were burned in open pits.

By late 1944, the war had clearly turned against Germany. The Soviet Red Army was pushing west after major victories. By the autumn of 1944, Soviet troops were moving through Eastern Poland.

The sound of artillery was getting closer to Auschwitz. The SS leadership understood that the camp could soon fall into enemy hands. That meant evidence.

Buildings, documents, witnesses. All of it could expose what had been happening since 1940.

In November 1944, Heinrich Himmler ordered the gas chambers at Auschwitz to stop operating and to be dismantled. This was not an act of mercy. It was about hiding crimes.

Crematoria 2 and 3 at Birkenau were partly dismantled. On January 20th, 1945, just days before Soviet troops arrived, SS guards blew up crematoria 2 and 3 with explosives. Documents were burned in large quantities.

The SS tried to erase traces of mass murder.

Mandel remained in her position at the women’s camp until January 1945. Even as the destruction of evidence was underway, daily life inside the camp stayed brutal. Prisoners were still starving.

Disease was still spreading. On January 17th, 1945, the SS leadership ordered the evacuation of Auschwitz. The next day, the mass evacuation began.

Around 56,000 prisoners from Auschwitz and its subcamps were forced to leave on foot in what became known as the death marches.

It was deep winter. Temperatures were below freezing. Many prisoners didn’t have proper shoes or coats.

Anyone who fell behind was often shot on the spot. Thousands died from cold, hunger, exhaustion, or execution during these marches. Mandel left Auschwitz before the Soviet army arrived.

On January 27th, 1945, Red Army soldiers entered the camp complex. They found around 7,000 prisoners still alive, most too sick or too weak to march. They also found piles of corpses, warehouses filled with human hair, shoes, and suitcases.

After leaving Auschwitz, Mandel was transferred to the Mühldorf subcamp, part of the Dachau camp system in Bavaria. Mühldorf was connected to a secret construction project known as Weingut 1, where prisoners were forced to build underground bunkers for aircraft production. Conditions there were also severe.

By early 1945, Germany was collapsing on all fronts. Allied forces were crossing the Rhine in the west. The Soviets were closing in on Berlin from the east.

On April 29th, 1945, US forces liberated Dachau. Just one day later, Adolf Hitler committed suicide in Berlin. On May 8th, Germany officially surrendered.

As the regime fell apart, many SS members tried to escape, change identities, or blend back into civilian life. Mandel was no exception. She returned to Austria and tried to disappear into ordinary society.

Allied authorities began hunting down SS personnel and camp staff. Survivors were giving detailed statements. Captured documents were being studied.

The names of guards and officers were recorded carefully. Mandel hoped that as a woman and not a top-ranking male officer, she might avoid attention. But her position at Auschwitz had been too high-profile.

Survivors remembered her clearly.

In August 1945, US forces arrested her. She was identified as a senior SS guard who had served at both Ravensbrück and Auschwitz. She was taken into custody and questioned.

Since Auschwitz was located in occupied Poland and most of the victims had died there, the Polish government sought custody of many camp personnel. In November 1946, Mandel was extradited to Poland to stand trial.

Her trial took place in Krakow before the Supreme National Tribunal of Poland. The proceedings became known as the Auschwitz trial. It began on November 24th, 1947.

40 defendants were charged, including former Auschwitz commandant Arthur Liebehenschel and other SS officers and camp officials. This was one of the largest post-war trials connected to Auschwitz. Mandel was one of the highest-ranking women among the accused.

The charges against her were severe. They included participation in selections that sent prisoners to the gas chambers, direct involvement in mass murder, abuse and mistreatment of prisoners, and crimes against humanity. During the trial, former prisoners testified in detail.

The court reviewed camp documents, transport records, and administrative files.

On December 22nd, 1947, the Supreme National Tribunal delivered its verdict. Several defendants received death sentences. Mandel was also sentenced to death by hanging.

There would be no long appeals. The crimes were clear. The court moved quickly.

She was executed on January 24th, 1948, at Montelupich prison in Krakow, at 36 years old.

Reports describe her execution as quick. There was no long delay between sentencing and carrying out the punishment. The tribunal had concluded that the scale of the crimes required the highest penalty under Polish law.

With her death, one of the most powerful female figures in the Auschwitz system was gone. The woman who had once walked through the barracks of Birkenau, deciding with a gesture who would live and who would die, had faced the final judgment of the law she had so completely abandoned.
