Bernice E. Hornung, 82, a former home economics teacher who worked as a Red Cross volunteer and as a tutor for World War II veterans, died Thursday at the National Orthopaedic and Rehabilitation Hospital in Arlington. Seh underwent hip surgery in August and recently had suffered cardiac arrest.

During World War II, Mrs. Hornung was in charge of a Red Cross canteen in Washington. She later worked as a volunteer teacher at the old Mount Alto Veterans Hospital.

She came to Washington in 1942 with her husband, Timothy G. Hornung, an Agriculture Department economist who died in 1975.

Mrs. Hornung was born in Springfield, Neb. She earned a bachelor's degree in foods and nutrition from the University of Nebraska and taught on the faculties of the Universities of Nebraska, Tennessee and Wyoming before her marriage in 1932.

She lived in Alexandria and was a member of the Order of the Eastern Star, the P.E.O., the Extension Wives Club, the American Home Economists and the First Presbyterian Church of Arlington.

Survivors include two brothers, John A. Elwell, of Mesa, Ariz. and George L. Elwell, of Garwin, Iowa; and four sisters, Mabel Stacy, of Lincoln, Neb.; Mildred Schobert, of Sidney, Neb., Ruth Christianson, of Bellevue, Iowa, and Margaret Storm, of Phoenix.

The family suggests that expressions of sympathy be in the form of contributions to the P.E.O. Education Loan Fund, P.E.O. Executive Office, 3700 Grand Avenue, Des Moines, Iowa, 50312.
