Abby Rockefeller (known as "Babs") was born in New York City on November 9, 1903, the only daughter of John D. Rockefeller, Jr. and his wife, Abby. After attending Brearly School and Miss Chapin's School, she pursued philanthropy, giving both personally and through various Rockefeller organizations. Privately, she supported such institutions as the Museum of Modern Art (founded by her mother), the New York Zoological Society, and the YWCA. She also served on the Board of Trustees of Memorial Sloan Kettering Cancer Center and the Rockefeller Family Fund.

Babs founded and was president of the Greenacre Foundation, an organization created to maintain and operate one or more parks in New York State for the public's benefit. She was instrumental in the establishment of Greenacre Park, a park and waterfall located on 51st Street in Manhattan.

Babs married three times, first to David M. Milton, who she divorced in 1943. She then married Dr. Irving H. Pardee, who died in 1949. In 1953 she married Jean Mauzé, a senior vice president of the United States Trust Company. Babs died on May 27, 1976 in New York City.
