Tomas Rothaus is a lifelong anarchist, antifascist, athlete, and father. He was born in Buenos Aires, Argentina, and his nomadic life led to him moving around with stops in Athens, Boston, Buenos Aires, and Paris, followed by longer stints in Germany, and more recently returning to Argentina. He has been involved with a range of organizations including the CNT-Vignoles, Collectif Anti Expulsions (Anti Deportation Collective), Barricada Collective, Northeastern Federation of Anarcho-Communists, Antifaschistische Linke International, and Acción Antifascista Buenos Aires. He has been a participant in militant demonstrations and antifascist mobilizations ranging from the 2001 Bush inauguration, the FTAA summit in Quebec, the G8 summit in Rostock, and the 2011 mobilization to stop the march of several thousand neo-Nazis in the city of Dresden. PM Press published his first two books, Another War Is Possible and Argentina, a Tale of Two Utopias.
