Martin Heidegger

Martin Heidegger (1889–1976) was a German philosopher, a foundational figure in phenomenology and existentialism. His 1927 masterpiece Being and Time reshaped 20th‑century ontology. Rector at Freiburg in 1933, he joined the Nazi Party—a controversial affiliation. Post‑war, he faced denazification but remained influential, impacting philosophy, hermeneutics, theology, psychology, and more.
