Viktor E. Frankl was an Austrian neurologist, psychiatrist, Holocaust survivor, and the originator of logotherapy, a type of existential therapy that focused on the search for meaning in life. The events of World War II he witnessed profoundly influenced his views on human resilience, suffering, and purpose. The main idea of Frankl’s work is that people will be able to find meaning, develop hope, and grow even in the most oppressive situations. His books, especially Man’s Search for Meaning, continue to be the pillars of psychology, philosophy, and self-improvement.
