Polly Pommer Slayton, 83, a resident of Annapolis since 1919 and active in business and Navy affairs there, died Wednesday at Anne Arundel General Hospital in Annapolis.

She was the widow of retired Navy Capt. Charles Churchill Slayton. In 1940, she and her husband opened the Annapolis Travel Service. She continued to operate it for three years after his death in 1956.

Born in New York City, Mrs. Slayton attended a teacher's college there and taught in Brooklyn elementary schools until her marriage in 1919.

After moving to Annapolis, she taught mentally retarded children in Glen Burnie for a number of years.

Mrs. Slayton had been chairman of the fine arts committee of the Maryland League of Women Voters. She was founder of the Naval Academy Women's Club and a member of the Naval Academy Chapel Guild.

An accomplished contralto, she had been director of a women's choral group in Annapolis and also had sung as a soloist at several churches. She was a member of St. Anne's Episcopal Church. She also belonged to Zonta, a businesswoman's club.

She is survived by a daughter, Mrs. Bradley Slayton Weyman, of Orange, Calif.; a stepson, retired Navy Capt. Morgan Slayton, of Greenbelt, and a step-daughter, Nancy Alton Slayton, of San Francisco.
