The nation's oldest man has died at 112.

The son of George Francis says his father died Saturday of congestive heart failure at a nursing home in Sacramento.

The son, 81-year-old Anthony Francis, says his father was born on June 6, 1896 in New Orleans, and that his only wife, Josephine Johnson Francis, died at age 63 in 1964.

UCLA gerontologist Dr. Stephen Coles, who maintains a list of the world's oldest people, says Francis was the oldest man living in the U.S., at 112 years and 204 days. Coles says the oldest living person in the world is Maria de Jesus of Portugal, who is 115 years and 109 days old.
