Ms. Campbell received her undergraduate degree from Barnard College in 1965 and her law degree from New York University School of Law in 1968. Following that she became a law professor at Georgetown University Law Center and Catholic University School of Law in Washington, D.C., and an attorney with the Center on Social Welfare Policy and Law (now the Welfare Law Center) in New York. The National Women's Law Center began when female administrative staff and law students at the Center for Law and Social Policy demanded that their pay be improved, that the center hire female lawyers, that they no longer be expected to serve coffee, and that the center create a women's program.Marcia Greenberger was hired in 1972 to start the program and Campbell joined her in 1978. In 1981, the two decided to turn the program into the separate National Women's Law Center.
