Ernesto "Che" Guevara (14 June 1928 – 9 October 1967) was an Argentine Marxist revolutionary, physician, author, guerrilla leader, diplomat, and military theorist. A major figure of the Cuban Revolution, his stylized visage has become a ubiquitous countercultural symbol of rebellion and global insignia in popular culture. As a young medical student, Guevara traveled throughout South America and was appalled by the poverty, hunger, and disease he witnessed.
