She was born in Santiago, Chile, in 1950. At the age of 19, she started studying Pedagogy in German at the University of Chile until 1973. Three years later, her life was hit by her father’s arrest and disappearance, the former leader National of the CUT and Sub Secretary General of the Communist Party in hiding, Víctor Manuel Díaz López.
This event marked Viviana’s path, placing her in a destiny that pursues truth, justice, and human rights defense. Thus, during the ’70s and’ 80s, she joined the work carried out by the Association of Relatives of Disappeared Detainees (AFDD), under the Committee for Peace protection and then the Vicariate of Solidarity. Viviana shared with the women who were living in her same situation, and she became part of the public protest actions carried out by the Association to find the truth.
After the country’s return to democracy, Viviana Díaz continued to participate in the activities of the AFDD, to obtain official recognition for the disappearance of her father. After Sola Sierra died in 1999, she headed the Association of Relatives of Detained and Disappeared until 2003.
In 2013 Viviana Díaz received, from the INDH – the first National Human Rights Award. Since 2013 she is part of the Advisory Council of the INDH.
