Disappearance
On November 17, 1961, Rockefeller and Dutch anthropologist René Wassing were in a 40-foot dugout canoe about three miles from shore when their double pontoon boat was swamped and overturned. Their two local guides swam for help, but it was slow in coming. After drifting for some time, Rockefeller said to Wassing "I think I can make it" and swam for shore. It is estimated that the boat was twelve miles from the shore when he made the attempt to swim to safety, supporting the theory that he died from exposure, exhaustion, and/or drowning. Wassing was rescued the next day, while Rockefeller was never seen again, despite an intensive and lengthy search effort. At the time, Rockefeller's disappearance was a major world news item. His body was never found. He was declared legally dead in 1964.
