Martin Heidegger (; German: [ˈmaʁtiːn ˈhaɪdɛɡɐ]; 26 September 1889 – 26 May 1976) was a German philosopher known for contributions to phenomenology, hermeneutics, and existentialism. His work covers a range of topics including ontology, technology, art, metaphysics, humanism, language and history of philosophy. In April 1933, Heidegger was elected as rector at the University of Freiburg and has been widely criticized for his membership and support for the Nazi Party during his tenure.
