Piero Sraffa, FBA (5 August 1898 – 3 September 1983) was an influential Italian economist who served as lecturer of economics at the University of Cambridge. His book Production of Commodities by Means of Commodities is taken as founding the neo-Ricardian school of economics.
Roberto Calvi (13 April 1920 – 17 June 1982) was an Italian banker, dubbed "God's Banker" (Italian: Banchiere di Dio) by the press because of his close business dealings with the Holy See. He was a native of Milan and was chairman of Banco Ambrosiano, which collapsed in one of Italy's biggest political scandals.
Calvi's death by hanging in London in June 1982 is a source of enduring controversy and was ruled a murder after two coroners' inquests and an independent investigation. Five people were acquitted in Rome in June 2007 of conspiracy to murder Roberto Calvi. Popular suspicion has linked allegedly corrupt officials of the Vatican Bank, the Sicilian Mafia, and the Continental Freemasonry lodge Propaganda Due to his death.
