Raymond J. Mondor, 61, ombudsman for the Smithsonian Institution and a retired official of the old U.S. Civil Service Commission, died of a cerebral aneurysm Sunday at Holy Cross Hospital in Silver Spring.

Mr. Mondor began his 36-year career with the U.S. Civil Service Commission in 1940 with the commission's regional office in St. Paul, Minn. cHe was an information clerk and held several other administrative positions before becoming an investigator and inspector, working mostly in St. Paul and for several years in St. Louis, Mo.

He transferred to commission headquarters in Washington in 1955 as an examining representative with the commision's bureau of recruiting and examining.

Mr. Mondor then held several other positions with the bureau of recruiting and examining here, including chief of the personnel operations section and chief of the administrative management division. He also served as first executive officer of the then newly created Interagency Board of Examiners for the Washington area in 1966.

His last job before retiring in 1976 was as director of the office of management analysis and audits for the commission, which later became the Office of Personnel Management.

After retiring, Mr. Mondor became a personnel consultant for the Smithsonian Institution in the division of performing arts.

He had served as the Smithsonian's ombudsman since 1977.

Mr. Mondor was born in Star Prairie, Wis. He earned a bachelor's degree in business administration from the University of Minnesota.

During World War II, he served in Europe as a captain in the Army Signal Corps and was awarded two Bronze Stars.

Mr. Mondor lived in Silver Spring. He served as president of the Holy Name Society at St. Bernadette Catholic Church there and was active in the St. Vincent De Paul Society.

Survivors include his wife of 33 years, Beneva L., and two sons, Mark and Alan, all of Silver Spring; two other sons, Raymond and Paul, both of Washington; three daughters, Christine Feher and Michele Mondor, both of Columbia, Md., and Marguerite Noga of Springfield, Va.; his mother, Anna Mondor, two brothers, Gilbert and Donald and a sister, Yvonne Parkhurst, all of Stillwater, Minn.; another brother, Walter, of St. Paul, and four grandsons.

The family suggests that expressions of sympathy be in the form of contributions to St. John the Baptist Catholic Church Community Fund in Silver Spring.
