Dr. Eugene Vinogradoff, 70, a retired Labor Department economist, died July 13 after a heart attack in Athens, Greece.

A resident of Fairfax County, where he had lived for the past 30 years in a home he built near Mount Vernon, he was stricken while on his way to visit his son, Dr. E. D. Vinogradoff, who is teaching in the Aegean School of Anthropology on the island of Naxos.

Dr. Vinogradoff had retired from the bureau of employment security in 1970 after more than 30 years with the Labor Department.

Born in Moscow, he fled from Russia with his father the day before the family made its way through Siberia to Vancouver, British Columbia, and then to New York.

Dr. Vinogradoff was educated as an electrical engineer at the Carnegie Institute of Technology and earned his doctorate in economics from the University of Pittsburgh.

He joined the Labor Department here in 1936. His work contributed to the development of the Dictionary of Occupational Titles. He also designed the means for collecting data, which the department used for many years as forecast measurements of unemployment.

He was a former executive director of the President's Committee on Scientists and Engineers.

After retiring, Dr. Vinogradoff was a consultant on employment matters in South America, the Far East and North Africa.

In addition to his son, he is survived by a daughter, Dr. Vera Burley, of Evergreen, Colo., and a sister, Vera Vacquier, of LaJolla, Calif.
