In an obituary in Sunday's edition of The Washington Post on Alexander Weinstein, 82, a retired mathematician at the University of Maryland who died Nov. 6, a city was wrongly identified. The obituary should have said that Dr. Weinstein taught in Breslau, Germany, now Wroclaw, Poland.

Alexander Weinstein, 82, a retired research mathematician at the University of Maryland, died tuesday at the Washington Adventist Hospital following surgery.

He had been the principle research mathematician at the university's Institute for Fluid Dynamics and Applied Mathematics for 18 years before his retirement in 1967.

Dr. Weinstein then continued his research at American University for a year and at Georgetown University for another four years.

He was born in Saratov, Russia, studied in Germany and recieved doctor's degree in mathematics from the University of Zurich in Switzerland in 1921. In 1926-27, he studied in Rome as a Rockefeller Foundation research fellow.

He returned to Zurich as a privatdocent for the noted mathematician, the late H. Wehl, who had been his teacher. Dr. Weinstien then taught in Hamburg, Germany, and Breslau, Poland, before moving to Paris in 1933. There he did research at the College de France and the Sorbonne, which gave him another doctorate in mathematics. He also studied in London and Cambridge, England.

Dr. Weinstein came to this country in 1940. He taught at the Free Fren French Unviversity in New York, the University of Toronto in Canada, Harvard University and the Carnegie Institute of Technology.

He was a consulting scientist at the Naval Ordance Laboratory here for two years before joining the University of Maryland faculty.

Dr. Weinstein had studied as both a Fulbright and a Guggenheim fellow. He was a member of the American Mathematical Society, the Academy of Correspondents of the National Acdemy of Sciences of Peru and the National Academy of the Lincei of Italy.

He is survived by his wife, Marianne, of the home in Silver Spring.
