 The remaining 45%, minus the $26 million left to Onassis' widow Jacqueline Kennedy Onassis, was left to the Alexander S. Onassis Public Benefit Foundation, established in honor of Aristotle's late son, and Athina's uncle.
 The two halves of the fortune are separately managed.
 Despite keen investigation by the media, the extent of Onassis' wealth remains unknown.
