Archaeologist and adventurer. He began adult life by seeking solitude and the simple life on a South Pacific island. He then sailed a balsa raft from South America to the South Pacific in order to help prove his theory that the Pacific had been populated in this way, a theory which has not won acceptance. He also excavated on Easter Island and in Peru, sailed another recreated ancient boat across the Atlantic to the Caribbean with a multi-national crew selected to highlight the principle of international amity and cooperation.
