Alec Kritini, 61, a retired information specialist for the Department of Health, Education and Welfare who later worked as a communications consultant, died of cancer Wednesday at the Chevy Chase Nursing and Convalescent Center.

A resident of Gaithersburg, Mr. Kritini came to this area after World War II. He worked in communications for a number of federal agencies, including the Public TPUBLIC Health Service and the National Institutes of Health, before joining HEW. He was assigned to HEW's engineering and environmental divisions before retiring in 1971.

He then began working as a consultant for the National Institute for Alcohol Abuse and Alcoholism, Montgomery County's Office of Comprehensive Health Planning and the Health News Services division of Capitol Publications Inc. in Washington.

Mr. Kritini was born in Rome. He came to this country as an infant with his mother, Russian Countess Galini Kritini, who died in 1958.

During World War II, he was an air operations specialist with the Army Air Corps in Europe, Africa and the Mideast.

He studied communications at American University.

Survivors include his wife, the former Clara Fielder, of the home in Gaithersburg; three daughters, Susan, of San Diego, Calif., Claudia, of Richmond, and Chantal Paradiso, of Annapolis, and one grandson.

The family suggests that expressions of sympathy be in the form of contributions to the American Cancer Society. CAPTION: Picture, ALEC KRITINI
