There have been intermittent attempts to view Wittgenstein's philosophy as phenomenology since the 1950s. In the 50s and 60s, with a virtual inaccessibility to the vast amount of the Nachlass materials, most attempts were limited to simple comparison of the themes and method of Wittgenstein's philosophy with those of Husserlian phenomenology. Although most philosophers who belonged to this trend failed to identify Wittgenstein's philosophy with phenomenology in any explicit manner, their contribution to the phenomenological interpretation of Wittgenstein's philosophy was important in the sense that they were the first to group Wittgenstein and Husserl together; for it means that they, at least, sensed the elements of phenomenology in Wittgenstein's philosophy.
