[1] Di Giovanni arrived in Buenos Aires with the last big wave of Italian immigrants before World War II.

He lived in Morón and travelled daily to Buenos Aires Capital to participate in meetings and plan actions against fascism and Italian fascist supporters in Argentina.

[1] An anarchist, Di Giovanni had nothing but contempt for the party in power, the UCR, which he saw as a pale reflection of more right-wing and fascist elements in Argentine politics.

[2] After being quickly released, Di Giovanni took part in international protests against the arrest and trial of Sacco and Vanzetti, members of the Galleanist anarchist group, who were accused of a robbery and murder of two payroll guards.

At the time, Di Giovanni was one of the most active anarchists in Argentina defending the two Italian immigrants, writing in various newspapers, including his own, founded in August 1925 and titled Culmine, and in the New York publication L' Adunata dei refrattari.

He summarized Culmine's objectives: On 16 May 1926, several hours after Sacco and Vanzetti's death sentence was announced, Di Giovanni bombed the U.S. embassy in Buenos Aires, destroying the front of the building.

On the following day, Di Giovanni and two of his anarchist comrades, Alejandro and Paulino Scarfó, blew up a statue of George Washington in Palermo, Buenos Aires,[5] and several hours later, exploded a bomb at the Ford Motor Company.

Di Giovanni wanted to bomb Hoover's train in revenge for the execution of Sacco and Vanzetti, but the bomber, Alejandro Scarfó, was detained shortly before installing the explosives on the rails.

In 1929, he wrote: Spending monotonous hours among the common people, the resigned ones, the collaborators, the conformists – isn't living; it's a vegetative existence, simply the transport, in ambulatory form, of a mass of flesh and bones.

[13]Following the September 1930 military coup, which overthrew Hipólito Yrigoyen, replaced by General José Félix Uriburu and Agustín P. Justo, Giovanni made plans to free his comrade Alejandro Scarfó from prison.

Needing funds to bribe the prison guards, he assaulted Obras Sanitarias de la Nación on 2 October 1930, achieving the most important robbery until then in Argentina, taking with him 286,000 pesos.

The police attempted to arrest him at a printing shop, but Di Giovanni managed to escape during a gun battle in which one policeman was killed and another injured.

[16] Franco's spirited defence of his client caused his own arrest after the trial; he was later dismissed from the ranks of the armed forces and briefly imprisoned before his deportation from Argentina.

Di Giovanni's body was to be buried secretly, on orders of the Interior Minister Matías Sánchez Sorondo, in La Chacarita Cemetery.

[17] After Di Giovanni's execution, Fina abandoned her husband Silvio Astolfi, and eventually remarried, settling down to a quiet life in Buenos Aires.

After serving a lengthy prison term, Astolfi returned to Europe and carried on with his antifascist activity: he was later killed during the civil war in Spain.

[15] On 28 July 1999, Fina Scarfó obtained the love letters which Di Giovanni had sent to her from prison decades earlier, but which had been seized by the police.
