Viktor Emil Frankl, M.D., Ph.D. (26 March 1905 – 2 September 1997) was an Austrian neurologist and psychiatrist as well as a Holocaust survivor. 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 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 sordid 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.
