Ann K. Ross, 89, a onetime civic activist who later became a head librarian at the D.C. Public Library, died March 20 at the Emeritus at Arlington, an Arlington County assisted-living facility.
She had dementia, her daughter-in-law, Carla Campell, said.
Mrs. Ross, an Arlington resident, worked at the D.C. Public Library for nearly two decades. She helped manage the library’s sociology division before retiring in 1988, her daughter-in-law said.
In the 1950s, Mrs. Ross was active in the Better School Movement, an effort to expand and improve the Arlington public schools. She also served as a vice chair of Arlingtonians for a Better County, a nonpartisan political coalition that supported racial integration in the public schools.
Dorothy Ann Klein was born in Alden, Iowa. She received a bachelor’s degree in 1943 and a master’s degree in 1945, both in home economics, from Iowa State University. She settled in Arlington in the 1940s. In 1967, she received a master’s degree in library science from Catholic University.
She received an award from the Arlington County Democratic Committee in 2004. Her memberships included the Arlington League of Women Voters and All Souls Unitarian Church in Washington, where she sang in the choir and participated in theater productions. She was also a volunteer at the Arlington Food Assistance Center.
Her husband of 59 years, Ronald Ross Sr., died in 2003.
Survivors include three children, Ronald Ross Jr. of Jenkintown, Pa., Elizabeth Ross of Brooklyn, N.Y., and Karl Ross of East Wallingford, Vt.; and a brother.
