Minnie S. Mondschein, 75, who worked in U.S. foreign assistance programs for 25 years, died of cardiac arrest Saturday at the Randolph Hills nursing home in Silver Spring. She had lived in Washington until moving to the Randolph Hills facility about two years ago.

Mrs. Mondschein was born in Baltimore and grew up in Detroit. She came to Washington in 1938 and began her government career a year later with the Department of Agriculture.

In 1941, she went to work for the World War II Lend-Lease program and remained with it after the war. She transferred to the Economics Co-operation Administration, which was formed to administer the Marshall Plan, as a fiscal accountant and reports analyst. She later joined the Development Loan Fund, a predecessor of the Agency for International Development. She retired from AID in 1967.

After leaving the government, Mrs. Mondschein spent a year in France, studying the language and pursuing her interest in art.

When she returned to Washington, she was a property manager for the Gellman Construction Co. until she retired a second time in 1975.

Her husband, Abe, and a son Earl died in 1960.

Survivors include a daughter, Bernice Sherbow of Israel; a son, Irwyn Mondschein of Silver Spring; three sisters, Anne Harris of Dayton, Ohio, Edith Pollack of Bethesda, and Sara Watman of Reston; three brothers Bernard Snyder of Cheverly, Louis Snyder of Silver Spring, and Sam Snyder of Detroit; 10 grandchildren and five great-grandchildren.
