SONRISAS DEL MAL: La Horripilante Verdad Sobre Esta Foto ‘Normal’ de los Guardias de Auschwitz

In a seemingly innocuous image, a group of uniformed men pose with beaming smiles by a crystal-clear pool, surrounded by women in summer swimsuits who laugh and raise their arms in carefree celebration. The sun shines on their relaxed faces, capturing a moment of leisure that could belong to any postwar family vacation. But this photograph, taken in the summer of 1944, evokes no idyllic memories of beaches or poolside afternoons. It belongs to a secret album that reveals the double lives of the executioners at Auschwitz, the largest Nazi extermination center where more than a million people perished. Behind those smiles lies a death machine operating at full capacity, and this disturbing truth forces us to question how monstrosity can disguise itself as everyday life.

The album in question, known as the “Höcker Album,” originated with Karl Höcker, an SS officer who arrived at Auschwitz on May 13, 1944, as deputy to Commandant Richard Baer. Höcker, a former bank employee who had led an uneventful life in pre-war Germany, became an essential cog in the “Final Solution.” His arrival coincided with the peak of horror at the camp: in just 55 days, the Nazis gassed more than 350,000 Hungarian Jews, many of them women and children torn from their homes in Budapest. Meanwhile, Höcker compiled 116 photographs that didn’t depict gas chambers or mass graves, but rather parties, singing, and outdoor escapes. The album was discovered in 1946 by a U.S. intelligence officer in a garbage container in an abandoned apartment in Frankfurt, and decades later, in 2007, it was donated to the United States Holocaust Memorial Museum.

These images, exhaustively analyzed by historians like Rebecca Erbelding of the same museum, paint a chilling portrait of perverse normalcy. In one of the most iconic photos, taken at Solahütte—a recreation resort built by the SS just a few kilometers from the Auschwitz fence—Höcker and his colleagues pose by the pool with expressions of pure delight. The women, SS secretaries and assistants, cool off in the water while the men, directly responsible for selecting victims for the gas chambers, chat animatedly. Erbelding, who spent months identifying those pictured, recalls the moment she recognized the infamous Josef Mengele, the “Angel of Death,” in one of the shots: “I hadn’t seen any trains or anything I recognized. It was the third time I’d turned the pages. And then I saw him: Josef Mengele.” No previous photograph had captured the Nazi doctor at Auschwitz, the man who conducted sadistic experiments on twins and prisoners, coldly selecting who would live another day and who would die that very afternoon.

The contrast between the jubilation in the photos and the invisible agony of the prisoners is what makes this album such a devastating document. While SS officers sang carols around a Christmas tree in December 1944—when the cold froze the skeletal bodies of the inmates on the death marches—thousands of souls were being incinerated in crematoria that operated without pause. In another image, Höcker offers blueberries to his secretaries, one of them feigning tears of sadness at having run out. “Here are blueberries,” reads the caption under the photo, a mundane detail that Erbelding describes as a brutal reminder of the disconnection from humanity. Outside the frame, smoke from the chimneys rose like a veil over the Vistula Valley, carrying with it the ashes of entire families.

This apparent banality of evil, as philosopher Hannah Arendt called it in her coverage of the Eichmann trial, finds an echo in the words of survivors who walked on the same contaminated ground. Irene Weiss, a 13-year-old prisoner who arrived at Auschwitz in May 1944—the same month as Höcker—lost her parents and four siblings in the initial selections. Forced to sort the belongings of the new arrivals near the gas chambers, Weiss watched as women and children were sent to their deaths without a trace of compassion on the faces of their captors. “Tears are for normal grief,” Weiss confesses in an interview with the museum, her voice still laden with the resignation learned in the face of horror. Regarding the guards, he adds without hesitation: “They were taught that they were doing it for a higher purpose. I knew they were animals.” His testimony, recorded on video, underscores how these men and women, photographed in poses of camaraderie, saw the Jews not as human beings, but as a plague to be eradicated in the name of a thousand-year Reich.

The playwright Moisés Kaufman, whose father and uncles were victims of Auschwitz, confronted these images when creating the play “Here There Are Blueberries,” directly inspired by the album. Kaufman, whose Jewish family was decimated in the Hungarian deportations of 1944, describes the visceral impact of the smiles in the photos: “To see it so clearly articulated in a photograph is terrifying. This is frightening because they all look so much like us.” Along with his collaborator Amanda Grunich, Kaufman explores in the play how these executioners didn’t wake up each morning planning atrocities, but rather justifying their routine with ideological beliefs. “They didn’t wake up thinking, ‘I’m an evil monster, I’m going to do monstrous things.’ They woke up every day and lived their lives full of justifications and convictions for what they did,” explains Grunich, highlighting the subtle erosion of empathy that the Holocaust allowed.

The legacy of the Höcker Album transcends the yellowed pages stored in a climate-controlled vault in Maryland. It has inspired exhibitions, documentaries, and debates about how Nazism recruited ordinary people—bankers, secretaries, amateur musicians—to perpetrate genocide. Tilman Taube, grandson of an SS doctor who visited Auschwitz and sent thousands to their deaths, reflects on this family legacy in terms of collective responsibility: “There are still so many facts to be uncovered. You want to be part of a movement that helps prevent things like this from ever happening again.” Her voice, tinged with generational shame, reminds us that the horror did not end with the liberation of the camp on January 27, 1945, but persists in the need to be vigilant in the shadows of normality.

Today, when we look at that “normal” photo of the Auschwitz guards, we see not only smiles frozen in time, but a mirror reflecting the fragility of humanity. In a world where hatred spreads through social media and veiled rhetoric
