The Tissue-Culture King (1926 in Cornhill Magazine and in The Yale Review, reprinted 1927 in Amazing Stories and many times afterwards) is a science fiction short story by biologist Julian Huxley. The story tells of a biologist captured by an African tribe. It incorporates the idea of immortality based on reproduction from a tissue culture and genetic engineering, and an early mention of tin foil hats and their supposed anti-telepathic properties.
