Rodolfo Jorge Walsh (January 9, 1927 – March 25, 1977) was an Argentine writer and journalist of Irish descent, considered the founder of investigative journalism. He is most famous for his Open Letter from a Writer to the Military Junta, which he published the day before his murder, protesting that Argentina's last civil-military dictatorship's economic policies were having an even greater and disastrous effect on ordinary Argentines than its widespread human rights abuses.
