Argentinian doctor; joined Castro in Mexico in 1954; a leader of the 1956-59 Cuban Revolution. Che served as president of Cuba's national bank and as Cuba's minister of industry in the period immediately following the Cuban Revolution. Towards the end of his formal affiliation with the Cuban government, Che came to implicitly criticize Soviet bureacracy. His positions put him at odds with the party line of the Cuban CP. In 1965, Che realized that the defence of the Cuban revolution and the creation of revolutions abroad were naturally not always in sync, and this ultimately led to his resignation and his return to revolutionary work abroad.
