In 1966, de Man attended a conference on structuralism held at Johns Hopkins University, where Jacques Derrida delivered his celebrated essay, "Structure, Sign, and Play in the Discourse of the Human Sciences"; de Man and Derrida soon became fast friends. Both were to become identified with Deconstruction. De Man came to reflect the influence primarily of Heidegger and used deconstruction to study Romanticism, both English and German, as well as French literature, specifically the works of William Wordsworth, John Keats, Maurice Blanchot, Marcel Proust, Jean-Jacques Rousseau, Friedrich Nietzsche, Immanuel Kant, G .W. F. Hegel, Walter Benjamin, William Butler Yeats, Friedrich Hoelderlin and Rainer Maria Rilke.
