Frankl, a contemporary of Freud, lost his whole family during the Nazi’s attempted extermination of the Jews. He developed his theory of “healing through meaning”, known as logotherapy, while a prisoner in the Auschwitz and Kaufering concentration camps. He counselled his fellow prisoners, many of whom were suicidal, with a philosophy that argued that striving for meaning, not pleasure nor power, is what keeps us alive.
Frankl was in one of the Kaufering sub-camps of Dachau.
Several years ago, I wrote about Viktor Frankl on this blog post: https://furtherglory.wordpress.com/2012/09/26/the-story-of-viktor-frankl-a-famous-holocaust-survivor/
Viktor Frankl is famous for making a mountain out of a mole hill. His life story promotes Holocaust denial. He was treated very well in the camps.
