Germany's most influential philosopher during the Weimar Republic years, and perhaps of the 20th century, was Martin Heidegger. Heidegger published one of the cornerstones of 20th-century philosophy during this period, "Being and Time" (1927). "Being and Time" influenced successive generations of philosophers in Europe and the United States, particularly in the areas of phenomenology, existentialism, hermeneutics and deconstruction. Heidegger's work built on, and responded to, the earlier explorations of phenomenology by another Weimar era philosopher, Edmund Husserl.
