Eraclio Petri, commonly known as Elio Petri, was an Italian film and theatre director, screenwriter and film critic. The Museum of Modern Art described him as "one of the preeminent political and social satirists of 1960s and early 1970s Italian cinema". His film Investigation of a Citizen Above Suspicion won the 1971 Academy Award for Best Foreign-Language Film, and his subsequent film The Working Class Goes to Heaven received the Palme d'Or at the 1972 Cannes Film Festival.
