“We are deeply saddened to learn of the passing of former Dutchess County resident and film, TV and stage icon, Mary Tyler Moore," Dutchess County Executive Marc Molinaro said. "She was a true trailblazer in the entertainment industry yet familiar face to us locally, leaving an indelible mark and impression on all who knew her and enjoyed watching her on the big and small screen. She was a role model for women everywhere and a distinct presence in our community.”
The eldest of three children, Moore was born Dec. 29, 1936 in Brooklyn Heights and also lived in Queens before her family moved to California when she was 8.
Moore, who married three times, had one child, a son, Richie, who died in 1980 at age 24 of an accidental gunshot wound.
