Viktor Frankl was the founder of
logotherapy, which is a form of
existential analysis, the "Third Viennese School of
Psychotherapy". His best-selling book
Man's Search for Meaning (published under a different title in 1959:
From Death-Camp to Existentialism, and originally published in 1946 as
Trotzdem Ja Zum Leben Sagen: Ein Psychologe erlebt das Konzentrationslager, meaning
Nevertheless, Say "Yes" to Life: A Psychologist Experiences the Concentration Camp) chronicles his experiences as a
concentration camp inmate, which led him to discover the importance of finding meaning in all forms of existence, even the most brutal ones, and thus, a reason to continue living. Frankl became one of the key figures in
existential therapy and a prominent source of inspiration for
humanistic psychologists
