Sir Julian Sorell Huxley FRS (22 June 1887 – 14 February 1975) was an English evolutionary biologist, humanist and internationalist.
He was born in London, and died there.
He was a proponent of natural selection, and a leading figure in the modern evolutionary synthesis.

He was Secretary of the Zoological Society of London (1935–1942), the first Director of UNESCO, and a founding member of the World Wildlife Fund.

Huxley came from the distinguished Huxley family.
His brother was the writer Aldous Huxley, and his half-brother, a fellow biologist and Nobel laureate, Andrew Huxley; and his paternal grandfather was Thomas Henry Huxley, a friend and supporter of Charles Darwin and proponent of evolution.

Huxley was well known for his presentation of science in books and articles, and on radio and television.
He was awarded UNESCO's Kalinga Prize for the popularisation of science in 1953, the Darwin Medal of the Royal Society in 1956, and the Darwin-Wallace medal of the Linnean Society in 1958.
He was also knighted in that same year, 1958, a hundred years after Charles Darwin and Alfred Russel Wallace announced the theory of evolution by natural selection.
In 1959 he received a Special Award of the Lasker Foundation in the category Planned Parenthood – World Population.
Huxley was a prominent member of the British Eugenics Society.
