L.Ron Hubbard published his Dianetics - the Modern Science of Mental Health in 1950. Shortly afterwards he founded the Church of Scientology, a religion which could, he claimed, cure 70 per cent of illnesses. Hubbard quickly became a multi-millionaire but his methods, particularly his alleged use of brainwashing, led to investigations in and exile from Britain, Australia and the USA. for the last few years of his life Hubbard was said to have become a Howard Hughes-like recluse.
