Hans Kamp is the founder of Discourse Representation Theory. From the Stanford Encyclopedia of Philosophy article on Discourse Representation Theory: “In the early 1980s, Discourse Representation Theory (DRT) was introduced by Hans Kamp as a theoretical framework for dealing with issues in the semantics and pragmatics of anaphora and tense (Kamp 1981); a very similar theory was developed independently by Irene Heim (1982). The distinctive features of DRT […] are that it is a mentalist and representationalist theory of interpretation, and that it is a theory of the interpretation not only of individual sentences but of discourse, as well. In these respects DRT made a clear break with classical formal semantics, which during the 1970s had emanated from Montague’s pioneering work […], but in other respects it continued the tradition, e.g., in its use of model-theoretical tools.”
