Judith Morris, 73, a Holocaust survivor who became an administrative assistant to the director of the Washington Hebrew Congregation and to the chairman of the Morris and Gwendolyn Cafritz Foundation, died Feb. 24 at her home in Washington.

She had cancer, said her companion, Marvin Weissberg.

Mrs. Morris settled in the Washington area around 1970 and did secretarial work for prominent lawyers and businessmen, including Milton Gwirtzman and Henry E. Catto Jr.

She served on the boards of the Washington Concert Opera, Woolly Mammoth Theatre Company, Jubilee JumpStart, a nonprofit child-care center, and the Weissberg Foundation, a philanthropic organization.

She also did volunteer work at J.O. Wilson Elementary School and the Martha’s Table food kitchen, both in Washington.

Judith Sarah Rosenblum was born in Brussels, where her parents were living after fleeing the Nazi regime in Germany. She was 3 when her father was captured by the Germans; he later died at the Auschwitz concentration camp. She was hidden in a Catholic orphanage, and her mother took refuge elsewhere. They were reunited five years later.

Mother and daughter immigrated to the United States, settling in New York City, where Judith completed high school in 1957 and became a U.S. citizen. She attended Hunter College at night while working for an accounting firm in New York.

Her marriage to Stan Morris ended in divorce.

Survivors include her companion of 15 years, Marvin Weissberg of Washington, Annapolis and Key West, Fla.; a daughter from her marriage, Courtney Morris of Santa Fe, N.M.; her companion’s two daughters, Nina Weissberg of Leesburg and Wesley Weissberg of Brooklyn, N.Y.; and six grandchildren.
