Which literary theorist is best known for introducing the concept of the 'author function'?

Explanation

The term 'author function' is a concept developed by Michel Foucault to analyze the role of the author in relation to texts, distinguishing it from traditional notions of authorship. While Claude Lévi-Strauss, Jacques Derrida, and Jacques Lacan have contributed significantly to literary and philosophical theory, the 'author function' is most closely linked to Foucault.
