Alice Scott Hyatt, 80, an official with the U.S. Children's Bureau for more than 30 years, died of a circulatory disorder Sept. 29 at her home in Rockville.

Mrs. Hyatt joined the Children's Bureau in 1924 after working on child welfare matters in Ohio for several years. In 1956, she received the Superior Service Award of the Department of Health, Education and Welfare, of which the Children's Bureau is now a part, and retired the following year.

She was a member of a commission for the revision of a Standard Juvenile Court Act, a member of the U.S. working group to the United Nations on juvenile delinquency, and a consultant to the juvenile court of Montgomery County.

Mrs. Hyatt was the widow of Judge Carl B. Hyatt, himself an expert in juvenile welfare.

Her professional affiliations included membership in the National Association of Social Workers, the American Public Welfare Association, and the National Probation and Parole Association.

Mrs. Hyatt was born in England and educated at Oberlin College and Western Reserve University in Ohio. She worked in Youngstown and Cleveland before moving to Washington and joining the federal government.
