With François Châtelet and others he in 1983 co-founded the Collège international de philosophie (CIPH), an institution intended to provide a location for philosophical research which could not be carried out elsewhere in the academia. In 1985 Sylviane Agacinski gave birth to Derrida's third child, Daniel.In 1986 Derrida became Professor of the Humanities at the University of California, Irvine, where he taught until shortly before his death in 2004. After Derrida's death, his widow and sons said they wanted copies of UCI's archives shared with the Institute of Contemporary Publishing Archives in France.
He had a significant influence upon the humanities and social sciences, including philosophy, literature, law, psychoanalysis and political theory.
His work retains major academic influence throughout continental Europe, South America and all other countries where continental philosophy has been predominant, particularly in debates around ontology, epistemology (especially concerning social sciences), ethics, aesthetics, hermeneutics, and the philosophy of language.
Some critics consider Speech and Phenomena (1967) to be his most important work.
Others cite Of Grammatology, Writing and Difference, and Margins of Philosophy.
He was awarded honorary doctorates by the University of Cambridge (1992), Columbia University, The New School for Social Research, the University of Essex, Katholieke Universiteit Leuven, the University of Silesia, the University of Coimbra, the University of Athens, and many others around the world.
Derrida's honorary degree at Cambridge was protested by leading philosophers in the analytic tradition.His wife, Marguerite, gave birth to their first child, Pierre, in 1963.In 1964, on the recommendation of Louis Althusser and Jean Hyppolite, Derrida got a permanent teaching position at the ENS, which he kept until 1984.During the Algerian War of Independence of 1954–1962, Derrida asked to teach soldiers' children in lieu of military service, teaching French and English from 1957 to 1959.Following the war, from 1960 to 1964, Derrida taught philosophy at the Sorbonne, where he was an assistant of Suzanne Bachelard (daughter of Gaston), Georges Canguilhem, Paul Ricœur (who in these years coined the term school of suspicion) and Jean Wahl.These writings influenced various activists and political movements.named him "Jackie", "which they considered to be an American name", though he would later adopt a more "correct" version of his first name when he moved to Paris; some reports indicate that he was named Jackie after the American child actor Jackie Coogan, who had become well-known around the world via his role in the 1921 Charlie Chaplin film The Kid.The university had sued in an attempt to get manuscripts and correspondence from Derrida's widow and children that it believed the philosopher had promised to UC Irvine's collection, although it dropped the suit in 2007.Derrida was a regular visiting professor at several other major American and European universities, including Johns Hopkins University, Yale University, New York University, Stony Brook University, and The New School for Social Research.In 1980, he received his first honorary doctorate (from Columbia University) and was awarded his State doctorate (doctorat d'État) by submitting to the University of Paris ten of his previously published books in conjunction with a defense of his intellectual project under the title "L'inscription de la philosophie : Recherches sur l'interprétation de l'écriture" ("Inscription in Philosophy: Research on the Interpretation of Writing").his 1980 dissertation was subsequently published in English translation as "The Time of a Thesis: Punctuations".
