Elizabeth M. de Schweinitz, 82, author, social worker and child welfare consultant, died of a pulmonary ailment Thursday at her Washington home.
Mrs. de Schweinitz had been a consultant in the 1950s to a special committee investigating overcrowding at the old Junior villge, a public welfare home for homeless D.C. children.
As a result of the study, Mrs. de Schweinitz submitted a report in which the city was criticized for shutting out many families in financial need only to have their children turn up at Junior Village at far greater expense for their care.
The facility eventually closed in 1973.
Mrs. de Schweinitz was a native of Benton Harbor, Mich. She earned a bachelor's degree at Oberlin College.
She worked for a time at a farm for delinquent girls in Pennsylvania, and then for the Social Security Board in New England during the 1930s where she helped state welfare programs qualify for federal matching funds under the Social Security Act.
In 1942, she moved to Washington where she worked for the Red Cross and on the administrative staff of the Women's Army Corps (WACS) in a civilian capacity.
She was the wife of Karl de Schweinitz, an author and an authority on social security and public welfare, who died in 1975.
Mrs. de Schweinitz traveled to Egypt and Britain where she assisted her husband in social and cultural studies.
She and her husband were co-authors of "Interviewing in Social Security," a booklet published by the Social Security Administration.
They also jointly received the Florina Lasker Award in 1962 for achieving "distincition nationally and internationally as professional social workers, teachers, authors and researchers."
Mrs. de Schweinitz is survived by stepson, Karl de Schweinitz Jr., of Evanston, Ill.; a stepdaughter, Mary Wood, of Swarthmore, Pa., and a sister, Gertrude McCord, of Albany, N.Y.
