Biscayart was born in La Plata on 31 August 1930.[1] She trained as a teacher in rural schools and as a social worker in the University Extension Department before going back to teach in her home town.[2]
During the 1950s, she was a member of the anarchist group Voluntad together with Pablo Tello, who later became her partner and the father of her three children:[3] Pablo Daniel (b. 25 April 1949),[4] Marcelo Rodolfo (b. 31 August 1950),[5] and Rafael Arnaldo (b. 13 April 1953).[6] The Tello Biscayart brothers worked as carpenters and, after the beginning of the Dirty War, the family joined Resistencia Libertaria (RL).[1]
Marcelo was the first to disappear, being abducted from his home in Córdoba in the early hours of 9 March 1976. Pablo and Daniel were later abducted from their workplace in Tigre on the afternoon of 31 May 1978. They were reportedly seen in "El Banco [es]" and "La Cacha [es]" before disappearing from record.[7] Biscayart's nephew, Eduardo Daniel Pereyra Rossi [es], was also abducted along with Osvaldo Agustín Cambiaso [es] in Rosario. They were murdered by a group under the command of Luis Patti.[8]
After the abductions, Biscayart herself went into exile in France and began a campaign to denounce the political persecution and crimes of the dictatorship in Argentina.[1] In Paris, she went to the Argentine embassy every Thursday to present her claims. She filed complaints with Amnesty International and the French judiciary and also sought help from film and art personalities.[9]
In 2009, Biscayart re-settled permanently in La Plata, where she testified in a trial regarding the case of the disappearance of her son Marcelo.[8] In December 2014, she participated in the First National Meeting against Impunity and Repression, which was promoted by dozens of organisations from all over the country.[1] Together with a delegation from the Assembly of Mexicans in Argentina, she demanded the appearance of the 43 missing students from Iguala.[8]
She died on 1 April 2015, in her home city of La Plata.[1]
