The von Wright and Wittgenstein Archives (WWA) in Helsinki contain all the Ludwig Wittgenstein materials collected by his friend, the Finnish philosopher Georg Henrik von Wright, who described it as “probably the most comprehensive and well-organized Wittgenstein archive in the world”. The Archives also contain much of von Wright’s correspondence and library, including most of his published and unpublished writings. Furthermore, WWA holds an extensive Wittgenstein library. It is thus a perfect spot for any Wittgenstein or von Wright-scholar, e.g., for someone interested in investigating the textual and editorial genesis of Wittgenstein’s philosophy. The staff of WWA also provides expertise in locating relevant material, and the WWA is an important research unit involving several cross-disciplinary research projects. Finally, WWA houses some unique memorabilia, such as Wittgenstein’s walking stick, the handkerchief used to cover his face after his death, and von Wright’s travelling typewriter from 1919.
