The world has had to wait a long time for this autobiography, for not only is Sir Julian Huxley over eighty years old but he achieved fame half a century ago. Born into one of the most gifted families of the age, he has yet made the name more famous by traditions to increase scientific knowledge and understanding. He has greatly contributed to the popularisation of science through his activities in writing, education, game parks in Africa and nature conservation in England, at the London Zoo, and his work at Unesco.
