Today, we open a historical file that contains no mention of ballistics or battlefield maneuvers. Instead, it speaks of an invisible force that consumed the futures of thousands of individuals without a single cry being heard. The setting is 1943, within the confines of Block 10 at the Auschwitz-Birkenau complex—a place where the fundamental principles of medicine were discarded, and the tools of healing were repurposed for destruction.
A Life Defined by a Shadow
My name is Adelle. I live alone in a modest apartment in Thessaloniki, overlooking the Aegean Sea. To my neighbors, I am simply a quiet, perhaps somewhat distant woman who rarely joins the laughter in the communal courtyard. They occasionally ask me why I never started a family, or why I have no grandchildren to accompany me on my walks along the promenade. I usually offer a polite deflection, attributing it to the whims of fate.
But that is a convenient fiction. It was not fate that intervened; it was a specific man. He was a man with a round face, spectacles, and a sterile white coat. He instructed me to sit on a wooden chair and remain perfectly still. If you were to see the physical toll I carry, you would understand the truth. My body does not bear the marks of motherhood; it is a map of trauma. It is a landscape of permanent damage where the possibility of new life was systematically extinguished.
The Arrival and the Second Selection
It began with a train journey, a shared beginning for so many of us. It was the spring of 1943. I was eighteen years old, full of the vitality of youth, with long dark hair and skin accustomed to the warmth of the Greek sun. When we arrived at the Birkenau ramp, the scene was the expected chaos: the barking of dogs, the harsh commands, and the pervasive mud.
However, on that particular day, there was a second screening. After the initial process managed by the camp doctors, another officer moved through the ranks. He wasn’t looking for manual laborers or those fit for heavy construction. He was looking for youth and specific physical characteristics.
“You,” he said, indicating me, “and you.” Approximately one hundred young women from Greece were selected.
We were separated from the main group. Curiously, they did not shave our heads immediately. We were escorted to a brick structure situated away from the primary camp sectors: Block 10. The windows were reinforced with wooden planks, obscuring the view from both sides. We were told we were the “lucky” ones—that we wouldn’t be performing hard labor, but would instead be contributing to “scientific progress.” At eighteen, I did not yet realize that in this context, “science” was the most ominous word of all.

The Humming Machines of Block 10
In the beginning, we were disoriented. The conditions seemed marginally better than the rest of the camp: we had sheets, the rations were slightly more substantial, and we were spared the grueling roll calls in the freezing snow. In our youthful optimism, we hoped we had found a sanctuary. We heard muffled cries from other floors, but we tried to convince ourselves we were safe.
The director of this facility was Horst Schumann. He did not possess the outward appearance of a villain; he looked more like a typical bureaucrat or an accountant. He moved through the wards without making eye contact, focused entirely on his ledgers and lists.
One morning in May, my name was called. I was directed to the first floor. I felt a sense of trepidation but not total panic. I assumed it was a standard hygiene check or perhaps a screening for typhus. I entered a large, sterile room. It didn’t smell like the rest of the camp; instead, it had a sharp, metallic scent—the smell of ozone, like the air right before a thunderstorm.
In the center of the room stood a lead-lined booth with a small viewing window. Positioned in front of it were two massive, imposing devices: industrial-strength X-ray machines. They emitted a low, continuous hum. An attendant directed me to undress, leaving only my shoes, and instructed me to sit on a simple wooden chair between the two machines.
The Invisible Fire
The attendant positioned two metal plates against my body—one against my lower abdomen and the other against the small of my back. The metal was freezing. I felt physically compressed by the machinery. When I asked what was happening, Dr. Schumann emerged from his booth and stated, in a flat tone, that it was a “treatment for internal parasites” required for staying in the block.
When you are desperate to survive, you accept even the most illogical explanations. He returned to his shielded booth, and the attendant left the room.
“Do not move,” Schumann commanded.
He activated the switch. The hum escalated into a mechanical roar. I heard violent electrical crackling. I braced for pain—for a cut or a burn—but initially, there was only a strange sensation of internal warmth. It wasn’t the heat of the sun on skin; it was a vibration deep within my pelvis.
I was unaware that millions of high-energy particles were passing through my body, targeted at my reproductive system. The goal was not “treatment,” but the permanent destruction of my ability to conceive. The process lasted ten minutes. I stared at a damp spot on the wall, counting the seconds, feeling an increasing sense of nausea and a metallic taste in my mouth. When the machines finally fell silent, Schumann checked his timer and simply called for the “next” subject.
The Aftermath of the “Treatment”
I returned to the dormitory on unsteady legs. My skin looked normal at first, and I told my friend Rosa that it was “nothing but a strange heat.” I didn’t realize that I was now a statistic in a report to Berlin. The objective had been achieved: total internal sterilization through a process that cost almost nothing and took mere minutes.
That evening, the first symptoms appeared. A deep, twisting cramp took hold. By the next morning, the entire ward was ill. We were vomiting and doubled over in pain, hoping it was just food poisoning. But then I looked at my stomach.
The skin had turned a deep, angry red in a perfect rectangle where the metal plate had been. Over the following days, the red turned to purple, then brown. The skin became taut and shiny. Blisters began to form—large, fluid-filled bubbles that burst at the slightest touch. The pain was so intense that we could no longer sit or lie down; we simply stood or crouched, trying to keep our clothing from touching the raw nerves.
When Schumann returned for a “check-up,” he showed no empathy. He pressed a gloved finger into the open wounds to test the depth of the tissue damage. He noted the results in his book: “Deep erythema… ovaries should be reached.” To him, we were not patients; we were experimental data points.
The Surgical Verification
X-ray burns are unique; they do not heal like typical burns. They penetrate deep into the muscle and bone, causing the tissue to deteriorate. The ward soon smelled of infection and decay. We became the “burned girls,” walking hunched over like the elderly.
But the radiation was only the first phase. Schumann needed to verify his “success.” Three weeks later, I was called to the operating room. This was not a place of healing, but a site of clinical butchery. I was placed on a table and given a local anesthetic that numbed my legs but left me fully conscious.
Schumann did not use a mask. He smoked a cigarette while he worked. He made a large incision directly through the burned, necrotic skin of my abdomen. I could hear the sound of the procedure—a sound I can never unhear. I stared at the ceiling as he moved my internal organs aside to find what he was looking for.
He removed one of my ovaries—now a shriveled, gray remnant—and placed it in a glass jar of preservative. He needed it for his physical report to demonstrate that the radiation had successfully destroyed the tissue. The assistant struggled to stitch the wound; the irradiated flesh was so fragile that the thread kept tearing through. I was returned to my bed, febrile and suffering from a severe infection. Schumann noted “probable peritonitis” and moved on. I was now considered “medical waste.”
Survival Against the Odds
I survived because of a hatred that burned brighter than my fever, and because of the clandestine help of prisoner-doctors like Dr. Alina. Without medicine or proper tools, she drained the infection from my wound and encouraged me to fight.
In January 1945, as the conflict neared its end, the camp was evacuated. We were forced into what became known as the “death marches.” We walked through sub-zero temperatures. Many fell and were left behind. I walked in a trance, feeling as though the “invisible fire” had turned my heart to stone.
The Long Silence
I returned to Thessaloniki in the summer. My family was gone. I was twenty years old, but I felt ancient. I eventually met Elias, another survivor. We married in 1948, and he spoke of the children we would have to “defeat the past.” I wanted to believe him, but my body remained silent.
A specialist in Athens eventually confirmed the truth: my reproductive system was “fibrosed,” as if a fire had swept through it. Schumann had succeeded. He had not only stolen my health; he had stolen my lineage.
For decades, I followed the news of my tormentor. Horst Schumann had escaped to Africa, living as a “respected doctor” for years before eventually being brought back to Germany for trial in 1970. I went to the courtroom, prepared to face him. But he appeared as a frail old man, claiming he was too ill to stand trial. The proceedings were suspended, and he died in his own bed in 1983, a free man who never expressed remorse.
The Legacy of the Last Witness
I am now 83 years old. I am one of the final voices from Block 10. Most of my friends from that time have passed away from the long-term complications of the radiation and the trauma.
I have no biological children, but I have my testimony. My “descendants” are the people who hear this story and understand its weight. Schumann managed to stop my family tree, but he could not silence the truth.
Every night, I touch the hardened skin of my abdomen. The scars remain, but my heart still beats. It beats for the youth that was stolen and for the future that was never allowed to begin. I am not merely a victim of history; I am its witness. Science divorced from ethics is a profound danger, and though human justice is often imperfect, memory is eternal. My name is Adelle, and this is the truth of the invisible fire.
