The couple remained married until William's death in 1971, after which Mavis remarried to David Harold Byrd on her birthday, February 14, 1974.

In 1950 he purchased Circle Bar Ranch[1] in Blanco County near the property of his long-time friend Lyndon B. Johnson.

Heath reentered public service in 1952, when Governor Price Daniel appointed him chairman of the Texas Board of State Hospitals and Special Schools.

On March 8, 1968, however, he was recalled to the United States in a demonstration of American displeasure with Swedish education minister Olof Palme's participation in an anti-Vietnam War protest that took place on February 21.
