In 1942, the Jewish Austrian psychologist Viktor Frankl was amongst those sent into concentration camps during the height of the Holocaust. His experiences in the camp, alongside the doctrine he would eventually come to name “Logotherapy,” were chronicled in the book, “Man’s Search for Meaning,” which would go on to sell over 10 million copies by 1997. In this book, both parts autobiography and scientific journal, Frankl chronicles his experiences and observations during his time in the concentration camp, both as a scientist and a prisoner. He would eventually go on to summarize those observations in a doctrine he titled the “Third Viennese School of Psychotherapy” ("Life of Viktor Frankl," 2020).
