In the framework of the history of social movements, Albert Einstein is, of course, mainly known for his efforts on behalf of the peace movement. Einstein never aligned himself with a political party, since he was scared of losing his independence. However, the positions he took certainly put him on the left-hand side of the political spectrum. A rummage through various archives at the IISH yielded dozens of documents and various visual artefacts.
A protocol to establish a radical pacifistic 'International Peace House', which he signed together with the Dutch clergyman J.B. Th. Hugenholtz (1888-1973) on 10 July 1932, never got off the ground due to Einstein's flight from the Nazis to Belgium and later to America. The Dutch artist Dirk Hart designed a share of one guilder to the International Peace House featuring EInstein.
