Michael Clark Rockefeller (May 18, 1938 – presumed to have died November 19, 1961) was the fifth child of New York Governor and former U.S. Vice President Nelson Rockefeller. He was the grandson of American financier John D. Rockefeller Jr. and the great grandson of Standard Oil co-founder John D. Rockefeller. He disappeared during an expedition in the Asmat region of southwestern Netherlands New Guinea, which is now a part of the Indonesian province of Papua. In 2014, Carl Hoffman published a book that went into detail about the inquest into his killing, in which villagers and tribal elders admit to Rockefeller being killed after he swam to shore in 1961. No remains or physical proof of Rockefeller's death have been discovered. Early life Rockefeller was the fifth and last child of Mary Todhunter Rockefeller and Nelson Rockefeller. He was the third son of seven children fathered by Nelson Rockefeller, and he had a twin sister, Mary. After attending The Buckley School in New York, and graduating from the Phillips Exeter Academy in New Hampshire, where he was a student senator and exceptional varsity wrestler, Rockefeller graduated cum laude from Harvard University with an A.B. in history and economics. In 1960, he served for six months as a private in the U.S. Army and then went on an expedition for Harvard's Peabody Museum of Archaeology and Ethnology to study the Dani tribe of western Netherlands New Guinea. The expedition filmed Dead Birds, an ethnographic documentary film produced by Robert Gardner, and for which Rockefeller was the sound recordist. Rockefeller and a friend briefly left the expedition to study the Asmat tribe of southern Netherlands New Guinea. After returning home from the Peabody expedition, Rockefeller returned to New Guinea to study the Asmat and collect Asmat art. "It's the desire to do something adventurous," he explained, "at a time when frontiers, in the real sense of the word, are disappearing." He spent his time in Netherlands New Guinea actively engaged with the culture and the art while recording ethnographic data. In one of his letters home he wrote: I am having a thoroughly exhausting but most exciting time here ... The Asmat is like a huge puzzle with the variations in ceremony and art style forming the pieces. My trips are enabling me to comprehend (if only in a superficial, rudimentary manner) the nature of this puzzle ... Disappearance On November
