Psychiatrist Viktor Frankl's memoir has riveted generations of readers with its descriptions of life in Nazi death camps and its lessons for spiritual survival. Between 1942 and 1945 Frankl labored in four different camps, including Auschwitz, while his parents, brother, and pregnant wife perished. Based on his own experience and the experiences of others he treated later.

Viktor Frankl was born in Vienna in 1905 and was Professor of Neurology and Psychiatry at the University of Vienna Medical School. His wife, father, mother and brother all died in Nazi concentration camps, only he and his sister survived, but he never lost the qualities of compassion, loyalty, undaunted spirit and thirst for life (earning his pilot's licence aged 67). He died in Vienna in 1997.
