Ludwig Binswanger

Swiss psychiatrist who founded Daseinsanalysis by translating Heidegger's existential phenomenology into a clinical framework for understanding mental illness as distortions of being-in-the-world.

Applied Heidegger's concept of Dasein (being-in-the-world) to psychiatry — arguing that mental illness represents a narrowing or distortion of an individual's existential world-structure, not merely a symptom cluster — founding the existential-analytic approach to psychopathology.
