From a Washington Post obit by Brian Murphy headlined “Carlos Alberto Montaner, Cuban exile writer who battled Castro, dies at 80”:

Carlos Alberto Montaner, a Cuban-born writer and columnist who was jailed as a teenager after Fidel Castro took power in 1959 and managed an escape, becoming a fierce opponent of the island’s communist ruler and a polarizing figure across Latin America with harsh critiques of politics and culture, died at his home in Madrid.
