Born in 1927, Walsh was killed in 1977 by a task force from the Navy School of Mechanics (ESMA), notorious for crimes against humanity, shortly after publishing his influential “Open Letter to the Military Junta.”

This letter, considered one of his most significant works, denounced the regime’s atrocities, including torture, disappearances, extermination camps, and the country’s subjugation to international financial powers.

The letter also condemned the imprisonment, murder, exile, and disappearance of tens of thousands following the 1976 coup against President Maria Estela Martinez. His remains, like those of many victims, remain disappeared.

In Cuba, Walsh is also remembered for his pivotal role in establishing Prensa Latina, the first Latin American media outlet designed to counter major information monopolies and disseminate truth globally. His work at Prensa Latina included deciphering secret cables revealing preparations for the Bay of Pigs invasion in 1961, which was ultimately defeated.
