Jacques Derrida (; French: [ʒak dɛʁida]; born Jackie Élie Derrida; 15 July 1930 – 9 October 2004) was a French philosopher. He developed the philosophy of deconstruction, which he utilized in a number of his texts, and which was developed through close readings of the linguistics of Ferdinand de Saussure and Husserlian and Heideggerian phenomenology. He is one of the major figures associated with post-structuralism and postmodern philosophy although he distanced himself from post-structuralism and disavowed the word "postmodernity".
