Falcone was born in 1939 to a middle-class family in the Via Castrofilippo near the seaport district La Kalsa, a neighbourhood of central Palermo that suffered extensive destruction by aerial attacks during the Allied invasion of Sicily in 1943. His father, Arturo Falcone, the director of a provincial chemical laboratory, was married to Luisa Bentivegna. Giovanni had two older sisters, Anna and Maria. Falcone's parents emphasised the importance of hard work, bravery and patriotism; he later said they 'expected the maximum' from him. At school Falcone would get into fights with larger children if he thought his friends were being picked on.
