Officials at the center say /*Betty Ford*/ approved the donation in mid-June, three weeks before her death on July 8. The rehab based in Rancho Mirage, Calif., is also slated to receive another $100,000 from a foundation former president Gerald Ford and his wife founded a decade ago.
The $500,000 donation was announced Wednesday.
Betty Ford co-founded the center that bears her name and has treated stars and non-celebrities alike since 1982. For years, she personally greeted patients, and the center says last year she granted the facility the rights to use her name forever.
