Bruce Ronald Henderson, also known as Bruce Grenville and Martin Renwick (born 1950), is a New Zealand anarchist, hoaxer and producer of artistamps. He is particularly known for the creation of the fictional Sultanate of Occussi-Ambeno.
Bruce Henderson was born in Wellington, New Zealand, in 1950.
In the 1970s and 1980s he gained notoriety for a hoax involving the fabrication of the utopian Sultanate State of Occussi-Ambeno, located as an exclave on the Island of Timor at Oecusse, with himself as the self-proclaimed Sultan. Stamps were produced for the "Sultanate".
In January 1999, he came to notice for the discovery of a long missing 1965 original episode of the BBC television series Doctor Who, discovered in a garage sale in Napier.
