Hubert Messner is a neonatologist who studied medicine in Innsbruck, Modena, Milan, and Graz. He worked as a pediatrician in Toronto and London, founded a neonatology department in Bolzano, and made it one of the best in Europe. A recognized expert in creating and improving the quality of care in departments for newborns and premature babies. A doctor’s work is like walking on the edge of a knife—balancing on the verge, through which you can learn so much. This realization comes to neonatologist Dr. Messner at moments of overcoming challenges—when, together with his brother, a legend in the world of mountaineering Reinhold Messner, he conquers the summit of Nanga Parbat, crosses Greenland, and heads for the North Pole. The value of life always comes first—this is the thought that helps him make the right decision in critical moments. He fights for the most fragile and vulnerable lives—this calling predetermined his entire future medical career. Passionately and with enthusiasm, Hubert Messner talks about his childhood and youth in the mountains, about his work as a neonatologist, about the most difficult cases from his practice, and about adventurous expeditions he took together with his brother.
