The grandson of Irish immigrants, Rodolfo Walsh was born in a small Patagonian town in 1927. He dropped out of high school in Buenos Aires and eventually began writing crime fiction before publishing his monumental work of nonfiction, Operación Masacre, in 1957. He traveled to Cuba in the midst of the revolution and launched a newspaper with Gabriel García Márquez, among others. Upon his return to Argentina in 1961 he was shunned by the journalistic community for his connections to the Cuban Revolution. In 1972, Walsh updated Operación Masacre for the fourth and final time before joining the radical Peronist group, the Montoneros, the following year. A day after submitting his now famous 1977 "Open Letter from a Writer to the Military Junta," Walsh was "disappeared" by the state.
