His father, Raffaele de Ferrari, came from an ancient and rich family of Genovese bankers and was a wealthy businessman made Duke of Galliera in Genoa by Pope Gregory XVI, and Prince de Lucedio by Victor-Emmanuel II, King of Italy. Raffaele de Ferrari was co-founder of the Credit Mobilier with the Pereire brothers, rivals of the Rothschilds, who financed many of the major construction projects of the second half of the 19th century: railroads in Austria, Latin America, Portugal, upper Italy and France (the Paris-Lyon-Marseille line), the digging of the Frejus Rail Tunnel and the Suez Canal, and the reconstruction of Paris designed by Baron Haussmann. It is said that Raffaele de Ferrari died stuck in one of his immense safes.
