Alberto Granado (August 8, 1922 – March 5, 2011) was an Argentine–Cuban biochemist, doctor, writer, and scientist. He was also the youthful friend and traveling companion of revolutionary Che Guevara during their 1952 trip around Latin America, and later founded the Santiago School of Medicine in Cuba. He authored the memoir Traveling with Che Guevara: The Making of a Revolutionary, which served as a reference for the 2004 film The Motorcycle Diaries, in which he was played by Rodrigo de la Serna. An elderly Alberto Granado makes a short appearance at the end of the film.
