The definitive biography of a radical activist and intellectual Max Eastman 1883-1969 was a prolific writer, radical, and public intellectual who helped shape the twentieth century. While researching this masterful work, acclaimed biographer Christoph Irmscher was granted unprecedented access to the Eastman family archive, allowing him to document little-known aspects of the famously handsome and charismatic radical. Considered one of the "hottest radicals" of his time, Eastman edited two of the most important modernist magazines, The Masses and The Liberator, and campaigned for women's suffrage and world peace. A fierce critic of Joseph Stalin, Eastman befriended and translated Leon Trotsky and remained unafraid to express unpopular views, drawing criticism from both conservatives and the Left. Set against the backdrop of several decades of political and ideological turmoil, and interweaving Eastman's singular life with stories of the fascinating people he knew and loved, this book will have broad interdisciplinary appeal in twentieth-century history and politics, intellectual history, and literary studies.
