Every person is unique. The renowned pediatrician and developmental researcher Remo Largo has mostly remained modestly silent about his own life, his love for the Glarnerland, his youth in Switzerland, and his experiences with his family. He only spoke late in life about the struggles and severe health challenges that shaped his existence, doing so in a few interviews, unpublished writings, and personal conversations with the author. He has always managed to turn difficulties into opportunities, thereby building an impressive body of work. This biography tells the story of the researcher and bestselling author Remo H. Largo and the person behind the name. The reason his books have been loved for decades is that he never wrote solely as a physician, but always as a humanist, seeker, doubter, and a family man deeply connected to nature and community.
