Dorothy Rowland Swift, 90, an editor with the Carnegie Institution and a past president of the Washington branch of the American Association of University Women, died April 23 at her home in Potsdam, N.Y., after a stroke.

Miss Swift, who lived in Washington from 1937 to 1957, was president of the Washington branch of the AAUW from 1950 to 1951. She had been active in efforts leading to the integration of the branch.

A native of Saratoga Springs, N.Y., Miss Swift was a 1912 graduate of Oberlin College, where she was a member of Phi Beta Kappa. Before moving to Washington she had been an editor with the University of Chicago Press.

After leaving Washington, she lived in Boston and was an editor with the Harvard University Press. She lived in New York City for 20 years, where was an editor with the Rockefeller University Press, before moving to Potsdam in 1980.

Miss Swift was a member of the Potomac Appalachian Trail Club and the American Civil Liberties Union.

Survivors include a sister, Janet H. Swift Jameyson of Berea, Ohio.

The family suggests that expressions of sympathy be in the form of contributions to CARE, or the U.S. Committee for UNICEF, both the New York City, or to the Sierra Club in San Francisco, or to Oberlin College in Oberlin, Ohio.
