A short life of the author
Sir Julian Sorell Huxley (1887–1975) was a British evolutionary biologist, science writer, and internationalist. He came from scientific royalty: grandson of T.H. Huxley (“Darwin’s Bulldog”), brother of the novelist Aldous Huxley, and half-brother of the Nobel Prize-winning physiologist Andrew Huxley.
Julian Huxley held academic positions at Oxford and King’s College London, was secretary of the Zoological Society of London, and served as the first Director-General of UNESCO (1946–1948). His major scientific contribution was Evolution: The Modern Synthesis (1942), which helped integrate Mendelian genetics with Darwinian natural selection into the framework that dominated evolutionary biology for the rest of the twentieth century.
He was also a tireless science populariser, writing books on bird behaviour, African wildlife, and the philosophy of science, and contributing to early nature documentaries.
Collecting Huxley
Evolution: The Modern Synthesis (1942, Allen & Unwin) first editions are important in the history of biology and bring $200–$600. His popular science books — Essays of a Biologist (1923), The Living Thoughts of Darwin (1939) — are more affordable. Signed copies exist from his long public career.
