Montoneros kidnapped the Born brothers, heirs to Bunge y Born, and freed them after nine months for a reported $60 million

Jorge and Juan Born were heirs to the grain trading group Bunge y Born. On 19 September 1974 the Montoneros guerrilla group ambushed Jorge and Juan Born in Buenos Aires. Alberto Bosch, Jorge's childhood friend and a manager at the group's Molinos Río de la Plata, was in the front seat and was killed; Jorge learned of his death in captivity. In December 1974 the Montoneros published a statement that the brothers had been brought before "popular justice". The kidnappers demanded 100 million dollars. The family's negotiator offered 15 million, then about 17.5 million by 24 December. Jorge kept a diary in what he called the "people's prison". His letters to his father helped persuade the family to pay. He was freed on 20 June 1975, after nine months. Jorge said in 2015 that the ransom was 60 million dollars for both brothers. A 2010 Clarín report, drawing on a book by Juan Gasparini, gives 63 million and says the banker David Graiver received about 14 million of it, handed over in Geneva in June 1975. Montoneros leader Mario Firmenich appeared unmasked at the end to say the deal was done. Born lived in Brazil for 17 years afterwards, and the family later sold the company.
