Mrs. Anthony also served as a member of the board of directors of the Hawaii Preparatory Academy and was the only woman member of the board of directors of the Santa Gertrudis Breeders International Association. Mrs. Anthony was a director and founder of the Hawaii School for Girls, a director of the Children's Hospital of Honolulu and a director of the James M. Cox Foundation.
As Chairman of Hualalai Land Corporation, Mrs. Anthony oversaw all aspects of a 7,500-acre ranch located on the slopes of Mt. Hualalai, Hawaii. Ranch operations include cattle breeding, sale of cut flowers and coffee production. Mrs. Anthony also was chairman of Winderadeen Corporation, Canberra, Australia, a commercial operation of 2,500 breeding cows and a sponsor of Ducks Unlimited. ...
Throughout her life, Mrs. Anthony was active athletically. She enjoyed "competing in anything that resulted in someone being declared a winner," said James C. Kennedy, Cox Enterprises Chairman and Chief Executive Officer and Anthony's son. She especially enjoyed tennis and equestrian events. She even competed in rodeos while spending summers at the family ranch near Stanley, Idaho.
Once, when attending a convention of newspaper publishers, she soundly defeated Washington Post publisher Katharine Graham on the tennis court. Kennedy asked her why she was so tough on Graham. "Kay would have done the same thing to me, if she could," Anthony told her son.
