Michael Clark Rockefeller was the third son and fifth child of the US Vice President Nelson Rockefeller. He was also the great-grandson of John Davison Rockefeller Sr. who was one of the co-founders of Standard Oil. Michael, a graduate of Harvard, was on a trip to Papua, New Guinea in Indonesia.

On November 17, 1961, Rockefeller and René Wassing (a Dutch anthropologist) were about three miles from the shore when their boat capsized. According to reports, Rockefeller managed to swim to shore, but that was his last sighting. Even after a two-week-long search that included helicopters, ships, airplanes, and thousands of people, Rockefeller could not be found.
His disappearance gave rise to conspiracy theories including the one where he was supposedly killed and eaten by cannibals. Michael Rockefeller was declared legally dead three years after his disappearance, in 1964. (source)
