A notorious Nazi war criminal known as the “Hangman of Buchenwald,” whose sadistic methods of torture and execution shocked even his own SS superiors, has been identified as Walter Gerhard Martin Sommer, a man whose name has become synonymous with the darkest depths of human cruelty during World War II.
Sommer, born in February 1915, rose through the ranks of Hitler’s Schutzstaffel to become one of the most feared figures within the concentration camp system, earning a reputation that preceded him wherever he went. Prisoners understood with terrifying certainty that if Sommer’s gaze fell upon them, they had perhaps five minutes before they would face torture or death.
His journey into infamy began at Dachau, the first concentration camp established after Hitler’s rise to power, where he quickly distinguished himself as a guard who treated prisoners with exceptional brutality and contempt. But it was at Buchenwald that his most horrific crimes would unfold, transforming him into a figure of pure terror within the camp’s barbed-wire confines.
The scale of suffering at Buchenwald was staggering. Within a secret medical facility constructed specifically for the purpose, 8,000 Soviet prisoners of war were systematically eliminated and executed. It was in this environment of industrialized death that men like Sommer flourished, their pathologies given free rein under the cover of ideological warfare.
What distinguished Sommer from other SS guards was not merely his capacity for violence but the particular creativity he brought to it. In 1943, Heinrich Himmler, the head of the SS, ordered Judge Georg Konrad Morgen to investigate corruption within Buchenwald. The investigation revealed that Commandant Karl Otto Koch and his wife Ilse had been stealing and embezzling funds taken from prisoners.
But alongside the Kochs, Sommer’s conduct came under scrutiny as well. Witness testimony revealed that the Hangman maintained a secret chamber beneath the floor of his office, a hidden space where he concealed an array of torture instruments. Among these tools were numerous syringes he used to execute prisoners by injecting carbolic acid directly into their hearts.
This was his signature method of killing, administered after prolonged torture sessions conducted within the confines of his office. It was also reported that he would inject air into his victims’ veins, causing fatal vascular blockages. The allegations painted a picture of a man who had transformed murder into a perverse art form.
According to witness accounts, Sommer would torture prisoners in the evening hours, then hide their bodies beneath his bed. In the morning, he would transfer the corpses to the crematorium where they would be burned, erasing all evidence of his nocturnal activities. The industrial efficiency of the camp’s death machinery provided perfect cover for his personal predations.
That the SS itself, an organization responsible for the genocide of millions, found Sommer excessively cruel speaks to the extraordinary nature of his sadism. He was, by their standards, a man who had gone too far, a guard whose brutality exceeded even the parameters of an institution designed for systematic cruelty.
Public floggings were among his preferred methods of degradation. Sommer would regularly whip prisoners at posts in full view of other inmates, forcing his victims to count the lashes aloud. If a prisoner made an error in counting, Sommer would restart the punishment from the beginning, extending their agony indefinitely.
Twenty-five lashes were sufficient to 𝓀𝒾𝓁𝓁 a man, reducing prisoners to masses of blood and broken flesh. Sommer allegedly administered sixty lashes to one man, causing immediate death. When he was later brought to trial, he displayed a chilling detachment, constructing a wooden model of the flogging post and explaining his technique with clinical precision.
His testimony, preserved in court records, revealed a man utterly devoid of remorse. He stated, “I cannot claim that I struck the final blows with the same force as the first. You always tire a little.”
The casual admission of fatigue as the only limitation on his capacity for violence underscored the monstrous nature of his character.
But even more disturbing allegations emerged against him. A specific group of people within Buchenwald faced his particular wrath: clergy and religious figures. He was observed beating a pastor from Weimar into a bloody heap on the ground, then allegedly hanging the man outside and pouring buckets of cold water over him, leaving him to freeze to death in the winter cold.
It was for his treatment of religious prisoners that he earned the title “The Executioner.” Evidence was uncovered that Sommer had murdered two Austrian priests in the forest near the camp. Buchenwald, which translates to “beech forest” in German, was surrounded by vast woodlands where numerous gallows had been erected.
Prisoners called this area the “singing forest” because the screams of the dying could be heard throughout the night, echoing through the trees. Many perished from frostbite during winter after being left hanging in the forest, their bodies slowly surrendering to the cold.
Otto Neururer and Matthias Spanlang were prominent priests imprisoned by the Nazis at Buchenwald for their resistance activities against Hitler’s regime. Neururer had been arrested after advising a woman not to marry a high-ranking Nazi official whose moral character was questionable. He was sent first to Dachau, then to Buchenwald.
At Buchenwald, Neururer became one of Sommer’s favorite targets for torture and 𝓪𝓫𝓾𝓼𝓮. The SS guard systematically destroyed and killed him over time. Within the camp, Neururer was tortured by Sommer after being caught performing a forbidden baptism ceremony, and for this transgression, Martin Sommer prepared a savage punishment.
The Hangman took Neururer and Matthias Spanlang into the forest and suspended both men upside down from a tree, crucifying them in a final act of humiliation. Both were stripped of their clothing. Over the course of thirty-four hours, Neururer was severely beaten until his body finally gave out and he died from his ordeal at the hands of Buchenwald’s executioner.
Spanlang was killed in the same manner. One witness claimed that neither man complained about their deaths, facing their end with a dignity that stood in stark contrast to the barbarity of their killer. Their sacrifice became a testament to faith and resistance in the face of absolute evil.
Sommer’s attacks on clergy continued. He allegedly beat a Catholic priest to death for performing another religious service within Buchenwald for a prisoner. The pattern was consistent: any expression of faith, any act of spiritual resistance, would be met with the most extreme violence.
He continued carrying out numerous hangings within the adjacent forest. Large groups were led into the woods daily by Sommer, and they never returned. Once they arrived, he would tie their hands behind their backs and hang them one by one from the trees.
The method was designed to maximize suffering. Prisoners were suspended in such a way that their hands remained behind their backs, with the entire weight of their bodies bearing down on their shoulders. This caused excruciating dislocations of the joints.
For hours, the prisoners would scream and weep, their cries echoing throughout Buchenwald.
Sommer’s psychological torment of prisoners was equally calculated. He claimed to be an emissary from Dante’s hell, asserting that he was Satan himself. Prisoners reported that he used the skull of one of his victims as a candle holder, placing a candle inside it to illuminate his office.
The macabre display served as a constant reminder of his power over life and death.
His methods of killing were varied and inventive in their cruelty. Beyond the lethal injections, he once placed a prisoner’s head in a metal vise and turned it until the prisoner’s skull was crushed. The diversity of his killing techniques suggested a mind that was constantly seeking new ways to inflict suffering.
Eventually, Sommer’s excesses attracted the attention of the highest levels of the Nazi hierarchy. Heinrich Himmler himself heard reports of Sommer’s brutality and ordered an investigation. The findings were damning even by SS standards.
It was determined that Sommer was too sadistic to remain a member of the SS.
He was stripped of his rank and sent to the Eastern Front to fight in a penal battalion. These units were typically deployed when situations became desperate, serving as frontline soldiers in the most dangerous combat zones. It was a form of punishment that often amounted to a death sentence.
On the Eastern Front, Martin Sommer was wounded, losing his right leg and left arm. He was captured as a prisoner of war by the Red Army. The Soviets released him in 1955, and he returned to West Germany, attempting to live a normal life.
He married, had a child, and even received a pension as a disabled veteran.
But justice, however delayed, eventually caught up with him. He was later tried for causing the deaths of at least 101 camp prisoners and was convicted of responsibility for the murders of 25 of them. The “Hangman of Buchenwald” was sentenced to life imprisonment.
He spent the remainder of his life either within prison walls or in a care facility from which he was not permitted to leave. The Hangman of Buchenwald died in 1988 at the age of 73, known throughout Germany as one of the worst war criminals of World War II.
Remarkably, despite his heinous crimes, he was not sentenced to death, and no execution was carried out against him. He was tried at a time when prison sentences were favored over capital punishment, a period when the Nazi who had sent so many to the gallows would not taste the same cup he had forced upon others.
He was a disturbed and sadistic individual, notorious within Buchenwald for his treatment of prisoners. But the crimes of the Hangman of Buchenwald were countless, and many remain undisclosed to this day. Historians continue to investigate the full scope of his atrocities, believing that the true number of his victims may never be known.
The case of Martin Sommer raises profound questions about the nature of evil and the capacity for human cruelty. How could a man derive such pleasure from the suffering of others? What allowed him to continue his reign of terror for so long, even within an organization dedicated to brutality?
Survivors of Buchenwald who encountered Sommer described him as a figure of almost supernatural menace, a man whose presence signaled imminent death. His memory haunted them long after liberation, a reminder that the monsters of the Holocaust were not abstract forces but individual human beings capable of unimaginable acts.
The documentation of Sommer’s crimes serves as a crucial historical record, ensuring that the horrors of the Holocaust are not forgotten or diminished. As the generation of survivors passes away, these accounts become ever more important in the fight against Holocaust denial and the distortion of historical truth.
The story of the Hangman of Buchenwald stands as a stark warning about the consequences of unchecked power, ideological extremism, and the human capacity for evil. It reminds us that civilization is fragile, and that the systems and institutions we create can either protect human dignity or enable its destruction.
For the families of Sommer’s victims, justice remained incomplete. While he was convicted and imprisoned, the death penalty was never applied, and many of his crimes were never fully investigated or prosecuted. The passage of time and the deaths of witnesses made comprehensive accountability impossible.
Yet the historical record remains, preserved in court documents, survivor testimonies, and the collective memory of those who endured the horrors of Buchenwald. The name Martin Sommer has become synonymous with the worst aspects of human nature, a cautionary tale about what happens when cruelty is institutionalized and rewarded.
As we reflect on this dark chapter of history, we must ask ourselves what lessons have been learned. The Holocaust did not happen overnight; it was the result of years of propaganda, dehumanization, and the gradual erosion of moral boundaries. The story of the Hangman of Buchenwald reminds us of the importance of vigilance against hatred and the necessity of holding perpetrators accountable for their crimes.
The legacy of Martin Sommer is one of infamy and horror. His life serves as a reminder that even within the most brutal regimes, some individuals distinguish themselves through their capacity for cruelty. The Hangman of Buchenwald will forever be remembered as one of history’s most notorious war criminals, a man whose name evokes the darkest period of the twentieth century.
