In the autumn of 1872, the ship Tegetthoff sailed north into the uncharted Arctic, carrying twenty-four men and a young Hungarian physician, Dr. Gyula (Julius) Kepes. Trapped in ice for 830 days, they faced hunger, disease, and despair. Yet through blinding blizzards and endless night, it was Kepes’s steady hand and quiet resolve that kept them alive. Doctor in the Frozen North tells the true story of a man nearly lost to history—a physician whose compassion and ingenuity defined the difference between life and death at the edge of the world. Drawing upon Kepes’s own medical reports, the journals of his crewmates, and a wealth of forgotten historical sources, Viktor Boiko reconstructs a vivid portrait of endurance and duty amid the desolation of the Arctic. Balancing historical authenticity with narrative grace, this work explores the limits of knowledge and faith in the face of the unknown. Where the record falls silent, imagination bridges the gaps; where history withholds its testimony, empathy gives voice. The result is both biography and re-creation—a chronicle of survival, science, and the quiet heroism of a man who refused to surrender to the ice.
