Gustav Landauer, who died in the Bavarian Revolution of 1919, was arguably the most significant German Anarchist of the twentieth century.
Despite this, his work is little known in England, where we perhaps have better knowledge of the Anarchist writers of the nineteenth century, or those from North America, Russia or Spain. Gabriel Kuhn has produced an English language reader of Landauer's writing that may change this tendency, especially if the book is as interesting as this interview, between Kuhn and Dov Neumann of the Jewdas group.
Gustav Landauer: Revolution and Other Writings: A Political Reader has been published by the North American Anarchist publisher PM Press. The cheapest I have spotted the book for in the UK is £21.59 courtsesy of Amazon - if any Anarchist movement bookshops or publishers are selling this title, do inform me and I will happily change the above link.
