Erwin Tegtmeier is a German analytic philosopher known for his work in formal ontology, particularly in the tradition of Gustav Bergmann's ontological realism. He has written extensively on states of affairs, universals, tropes, and the metaphysics of relations, defending a realist ontology against nominalist and trope-theoretic alternatives.
