Here is the person biography:
James Child Drury was born in New York, the son of Beatrice (Crawford) and James Child Drury. His father, from an Irish family, was a professor who lectured in marketing and advertising at New York University. Young James spent some of his formative years on a family ranch in Salem, Oregon, where he learned to become an expert rider.
His maternal grandfather, John Hezekiah Crawford, of Kentucky, educated him in the ways of the woodsman and taught him marksmanship. James began to act in school plays, toured with a theatrical company by the age of twelve and then studied drama at his father's university.
He completed his senior year at UCLA studying not acting but horticulture and animal husbandry. Upon graduation, he was signed to a contract by Metro-Goldwyn-Mayer and made his first screen appearance a year later in 1955.
Aside from playing junior army officers and assorted teenagers in films for 20th Century Fox and Disney, Drury quickly found a comfortable niche in TV westerns (which, no doubt, had much to do with his expertise in horsemanship).
