Anne Cox Chambers died Friday in Atlanta. She was 100.

Chambers and her sister, Barbara Cox, who died in May 2007, were owners of the privately held Cox Enterprises since 1974, when their brother, James M. Cox Jr., died and control of the family trust passed to them. Chambers served on the Cox board of directors and retained the title of Chairman of Atlanta Newspapers.

Chambers was named ambassador to Belgium during President Jimmy Carter’s administration and was a dedicated supporter of many causes and institutions including Atlanta Symphony Orchestra, the Atlanta Botanical Garden, the Atlanta Speech School, the Atlanta Humane Society, Communities in Schools and the High Museum of Art. She was a charter member of the Forward Arts Foundation.

Chambers is survived by children Margaretta Johnson Taylor, Katharine Johnson Rayner, and James Cox Chambers; four grandchildren, seven great-grandchildren, one niece, one nephew and a host of loving relatives and friends.

Friends and family are invited to a celebration of life at 2 p.m. Thursday at All Saints’ Episcopal Church, 634 W. Peachtree Street NW.
