Huxley grew up at the family home in Surrey, England, where he showed an early interest in nature, as he was given lessons by his grandfather, Thomas Henry Huxley.
When he heard his grandfather talking at dinner about the lack of parental care in fish, Julian piped up with "What about the stickleback, Gran'pater?".
His grandfather also took him to visit Joseph Dalton Hooker at Kew.
At the age of thirteen Huxley attended Eton College as a King's Scholar, and continued to develop scientific interests; his grandfather had influenced the school to build science laboratories much earlier.
At Eton he developed an interest in ornithology, guided by science master W. D. "Piggy" Hill. "
Piggy was a genius as a teacher ... I have always been grateful to him."
In 1905 Huxley won a scholarship in Zoology to Balliol College, Oxford and took up the place in 1906 after spending the summer in Germany.
He developed a particular interest in embryology and protozoa and developed a friendship with the ornithologist William Warde Fowler.
In the autumn term of his final year, 1908, his mother died from cancer at  the age of 46.
In his final year he won the Newdigate Prize for his poem "Holyrood".
In 1909 he graduated with first class honours, and spent that July at the international gathering for the centenary of Darwin's birth, held at the University of Cambridge.

Huxley was awarded a scholarship to spend a year at the Naples Marine Biological Station where he developed his interest in developmental biology by investigating sea squirts and sea urchins.
In 1910 he was appointed as Demonstrator in the Department of Zoology and Comparative Anatomy at the University of Oxford, and started on the systematic observation of the courtship habits of water birds such as the common redshank (a wader) and grebes (which are divers).
Bird watching in childhood had given Huxley his interest in ornithology, and he helped devise systems for the surveying and conservation of birds.
His particular interest was bird behaviour, especially the courtship of water birds.
His 1914 paper on the great crested grebe, later published as a book, was a landmark in avian ethology; his invention of vivid labels for the rituals (such as 'penguin dance', 'plesiosaurus race' etc.)
made the ideas memorable and interesting to the general reader.

In 1912 Huxley was asked by Edgar Odell Lovett to take set up the Department of Biology at the newly created Rice Institute (now Rice University) in Houston, Texas, which he accepted, planning to start the following year.
Huxley made an exploratory trip to the United States in September 1912, visiting a number of leading universities as well as the Rice Institute.
At T. H. Morgan's fly lab (Columbia University) he invited H. J. Muller to join him at Rice.
Muller agreed to be his deputy, hurried to complete his PhD and moved to Houston for the beginning of the 1915–1916 academic year.
At Rice, Muller taught biology and continued Drosophila lab work.

Before taking up the post of Assistant Professor at the Rice Institute, Huxley spent a year in Germany preparing for his demanding new job.
Working in a laboratory just months before the outbreak of World War I, Huxley overheard fellow academics comment on a passing aircraft "it will not be long before those planes are flying over England".

One pleasure of Huxley's life in Texas was the sight of his first hummingbird, though his visit to Edward Avery McIlhenny's estate on Avery Island in Louisiana was more significant.
The McIlhennys and their Avery cousins owned the entire island, and the McIlhenny branch used it to produce their famous Tabasco sauce.
Birds were one of McIlhenny's passions, however, and around 1895 he had set up a private sanctuary on the Island, called Bird City.
There Huxley found egrets, herons and bitterns.
These water birds, like the grebes, exhibit mutual courtship, with the pairs displaying to each other, and with the secondary sexual characteristics equally developed in both sexes.

In September 1916 Huxley returned to England from Texas to assist in the war effort.
