Picked this up from the Washington Post:

Cliburn was born Harvey Lavan Cliburn Jr. on July 12, 1934, in Shreveport, La., the son of oilman Harvey Cliburn Sr. and Rildia Bee O’Bryan Cliburn. At age 3, he began studying piano with his mother, herself an accomplished pianist who had studied with a pupil of the great 19th century Hungarian pianist Franz Liszt.

The family moved back to Kilgore within a few years of his birth.

Cliburn won his first Texas competition when he was 12, and two years later he played in Carnegie Hall as the winner of the National Music Festival Award.

My family had a music store when I was growing up, and Van Cliburn was generally considered a demigod at least by every piano teacher in the Southwest — the Texas boy who had beaten the Soviets at their own game, winning the First International Tchaikovsky Competition so decisively the Russians couldn’t deny it. I met him once when I was about 10, and vaguely recall that he seemed awfully young — he would have been about 36 — and that he seemed to have big hands.

He died of bone cancer in Fort Worth, where he made his home.
