Her professional memberships included the American Personnel and Guidance Association, American Psychotherapy Group Association, and the Community Psychiatric Clinic of the Johns Hopkins Hospital.
She sponsored a Girl Scout troop in earlier years and volunteered at the Red Cross and in the political campaigns of Parren J. Mitchell and Benjamin L. Cardin.
For many years, she was a communicant of St. Michael and All Angels Episcopal Church, where she had served on the vestry and was a lay minister.
Through her church, she organized an after-school program for children at Dallas-Nichols Elementary School, which gave them access to computers and a tutorial program.
"The program sought to prepare the children for state assessments and saw an improvement in the reading and math skills of the children because of this program," her daughter said.
For the last 32 years, Mrs. Finney lived at Winthrop House on North Charles Street, where she served on the condominium board and was a committee chair.
Mrs. Finney was a world traveler; some of the destinations she visited included the Great Wall of China, Tiananmen Square, Egypt, Shanghai, Jerusalem and London.
"She was even propositioned by an Italian count for a romantic tryst but declined," said Ms. Stewart with a laugh.
Mrs. Finney never lost her taste for civic activism or fighting injustice. In 2003, she was arrested with other members of The Women in Black, who marched in downtown Baltimore protesting the U.S. involvement in the Iraq War.
"She wore her arrest like a badge of honor and was tickled pink that her fight to stop a war garnered such attention by law enforcement and the media," her daughter said.
Mrs. Finney was communicant of the Episcopal Church of the Redeemer, 5603 N. Charles St., where a celebration of her life service will be held at 10:30 a.m. June 1.
In addition to her daughter, Mrs. Finney is survived by another daughter, Joan E. Smothers of Mount Washington; and a grandson.
