David Graiver (1941 — 1976) was an Argentine businessman and banker who was investigated in the 1970s for alleged money laundering of US$17 million for the Montoneros, a leftist guerrilla group. He was indicted for embezzlement after his reported death by Manhattan District Attorney Robert Morgenthau, who had thought he might have faked his death, because of the September 15, 1976 failure of American Bank & Trust. This was the fourth-largest bank failure in United States history at the time, and Graiver's banks in Argentina and elsewhere also failed. A New York court declared Graiver officially dead on January 15, 1979, clearing the way for resolution of some outstanding financial issues.
