Roberto Muniz, nicknamed "Mahmoud the Argentinian," was a revolutionary fighter who joined the National Liberation Army in 1959 to support the Algerian cause in the war of independence against France. He joined a clandestine group that manufactured weapons and ammunition to be transported to Algeria to support the revolution that began in 1954. After the war, the Algerian government invited the mujahid to stay, an offer he accepted to begin a new life as an employee of Sonnelgaz and a member of the General Union of Algerian Workers (UGTA), accompanied by his wife Alfonsa, a textile union activist who came from Argentina to join this North African adventure.
