If you want to understand postmodernism – you need to start with this guy. Jaques Derrida was a French philosopher best known for developing a form of semiotic analysis known as deconstruction which he developed within the philosophy of Phenomenology. He is one of the major figures associated with post-structuralism and postmodern philosophy. He actually decoupled words from their meaning. He is the grandfather of the chaos that has devoured modern western thought, literature and art.
