Mazel tov, Armand Hammer.

The 92-year-old billionaire industrialist will be pronounced a man next month when he celebrates his bar mitzvah, 79 years late, in a swank ceremony studded with Hollywood celebrities.The ceremony, signaling the entry of a Jewish male into manhood at age 13, is anticipated as officials at his Occidental Petroleum are making the most cautious of statements about the philanthropist's health. He appeared less than robust at a dinner Sunday celebrating the opening of his new art museum.

The ceremony is traditionally held on a Saturday morning at a synagogue. Hammer's bar mitzvah will instead be on a Tuesday night, Dec. 11, at a Beverly Hills benefit for two Jewish institutions.
