[1] Almada was born in 1937 in Puerto La Esperanza, in the Alto Paraguay Department, but moved with his family to San Lorenzo, near the capital Asunción, when he was six.

[citation needed] In 1972, he became the president of the Association of Educationalists of San Lorenzo, a local action group that received support from other sections of society and positioned itself in opposition to the dictatorship ruling Paraguay at the time.

[3] Almada went into exile with his mother and his children, at first in Panama and wrote a book Paraguay: The Forgotten Prison, the Country in Exile[3] about torture he and, most importantly, others suffered and whose names and faces he well remembers, and the extensive network of corruption through which the country was "run" by a dictatorship dedicated to an absurd anti-communism in the practical absence of any communist movement worth speaking of, actually a mask for the suppression of any even marginally left-leaning idea or practice.

[citation needed] In 2020, Almada was the subject of book Opération Condor written by French author Pablo Daniel Magee.

[citation needed] In 1992 Almada and his team discovered five tons of documents at the Department of Investigations, Lambaré which revealed dire practices of the Alfredo Stroessner dictatorship and links to the US government's CIA agents' involvement in Southern Cone countries at the time.
