She had served on the board of the Capitol Hill Day School and several city PTA groups. She had been a secretary and member of the executive board of the D.C. Youth Orchestra in the mid-1970s.

Mrs. Abraham was a native of Ohio and had lived in Washington since 1944. She was a 1940 graduate of the University of Toledo and earned a master's degree in art history at Radcliffe College in 1943. She also did graduate work in fine arts at Johns Hopkins University.

She was a member of the Davies Memorial Unitarian Church in Temple Hills. She had been president of the Naval Research Laboratory's wives' club. She was a member of the Radcliffe Club of Washington.
