This paper addresses the biographies of militants involved in the libertarian collectives from the 20s to mid- twentieth century. Based on the methodological approaches of sociology of criticism, from the postulates of Bernard Lahire, this approach aims to make visible experiences, identities, lives and experiences of political participation and some of the references of anarchism in Argentina: Jose Grunfeld, Juan Lazarte, Jose Maria Lunazzi, Jacobo Magid, Herminia Brumana, Iris Pavon and Ana Piacenza. On the other hand, the gender perspective allows us to observe the different paths of men and women as performative strategies of "being" and anarchist conception of political action.
