Tom Neale (1902-1977) was born in New Zealand and lived on several Pacific islands, including Tahiti and the Cook Islands, pursuing odd jobs. In 1952 he moved to the island of Anchorage in the Suwarrow Atoll to live off and on as a solitary.
Neale’s story is told in his book, An Island to Oneself, which is available on the web. A number of websites about Neale include photos and biographical details.
