Pulp science fiction writer turned ostensible self-help guru with the publication of his book Dianetics: The Modern Science of Mental Health. Dianetics spawned, under Ron's leadership, Scientology. A tyrannical cult/sect ruler and apparent pathological liar, Hubbard sailed the high seas, continuing to fabricate great whacks of fake science to keep his followers enthralled and paying. They still are, even though he's gone. Deposed on his deathbed by David Miscavige.
