Rafael Spósito Balzarini (21 May 1952 – 24 August 2009), better known by the pseudonym Daniel Barret, was a Uruguayan sociologist, journalist, university professor, and militant anarchist. Biography. Barret was born and lived in Villa del Cerro, a working-class Montevideo neighbourhood. He became involved with anarchism as a youth. He was involved as an organiser in the student movement, and later the labour union movement. He joined, and later left, the "Federación Anarquista Uruguaya" (Uruguayan Anarchist Federation). Because of the repression of anarchist and leftist movements in Uruguay during the 1970s, Barret moved to Buenos Aires, Argentina - although following the 1976 coup d'état he returned to Uruguay. With the end of the Uruguayan dictatorship, Barret took part in the relaunch of the "Federación Anarquista Uruguaya", however he again removed himself from the movement as a result of significant ideological differences. Following this, Barret became involved independently in various libertarian projects and committed his energy to libertarian journalism and sociology. Until 1999, Barret was a university professor in Montevideo. He was a member of the International Advisory Board for the "International Journal of Inclusive Democracy". He contributed to a variety of anarchist publications including ¡Libertad! (Buenos Aires), "El Libertario", and "Tierra y Tempestad". Barret died of cancer in Montevideo on 24 August 2009.
