Bettin Stalling, former chief of the Veterans Administration loan program and a former president of the Federal Bar Association, died of cancer Tuesday at Georgetown University Hospital. He was 80.

Mr. Stalling was a lawyer who specialized in housing throughout much of a government career that spanned 25 years. He began with the Home Owners Loan Corp. in 1934, and remained with that organization in Washington and Chicago for 14 years. In 1948, he moved to the Veterans Administration, and in 1950 became chief of the direct loan operations that helped thousands of World War II servicemen buy their own homes. Mr. Stalling remained in that job until 1954.

In that year, Mr. Stalling was elected presented of the Federal Bar Association, which now has about 15,000 members. They include government lawyers and other who practice before Federal agencies.

After two years at the General Accounting Office, Mr. Stalling went to Spain as a counsel for the Navy. He remained there for five years, and retired from the government in 1961.

Since then, he had remained active in community affairs and in private law practice. In the early 1960s, he represented the Adams - Morgan Planning Committee and Community Council, a group that sought to preserve the "international flarvor" of the neighborhood.

Later, he served on the Municipal Planning Council of the District of Columbia and on the Mayor's Economic Advisory Committee.

Mr. Stalling was born in Lexington, Mo. He earned a law degree from the University of Chicago and practiced there before entering federal service.

He was a member of the Cosmos Club and the National Lawyers Club.

Survivors include his wife, Lucy Ruth, of the home in Washington; a son, Dr. Richard B. Stalling, of Peoria, Ill.; two sisters, Mrs. W. H. Cohrs and Mrs. Hubert Simpson, both of Lexington, and two grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the Butterfield Youth Ranch, Marshall, M o.
