Viktor Emil Frankl was a Jewish-Austrian Psychiatrist and neurologic who founded Logotherapy. He published 32 books, among them the most famous "The Man's Seeking for Meaning" that describes his experience as a prisoner in Nazi concentration camps, including Auschwitz-Birkenau, and emphasizes the central importance of finding a destination in life to overcome trauma.
