Ami C. Stewart, 81, founder and former publisher and editor of The Georgetowner, died Monday at the Wisconsin Avenue Nursing Home, where she had lived for the past two years.

She established the biweekly newspaper in 1954 to present Georgetown news and advertising to its residents.

The first issue of about eight pages came off the press on Oct. 7, 1954. Today the tabloid, reportedly the oldest in the city, average 24 to 28 pages and has a circulation of about 20,000.

The newsroom is located on the second floor of 1203 28th St. NW. The paper is published with offset printing.

Mrs. Stewart, who was born in Portsmouth, Ohio, attended an art school in New York. She was an artist there before coming to Washington in the early 1950s, when her husband, Murray Stewart, took a job with the government. They settled in Georgetown.

He died a short time after they came here. She continued to live in Georgetown and began selling advertising from Georgetown merchants to The Evening Star. She then developed her own newspaper, and it expanded along with the growth of Georgetown.

Two or three persons eventually formed a staff to help her, with Carol Watson providing most of the assistance for 10 years.

Mrs. Steward did most of the interviewing and quite a bit of the writing. The paper provided information on civic meetings, shopping news and profile on Georgetown personalities. These included John F. Kennedy and other senators, congressmen, diplomats and other Georgetown residents.

Mrs. Stewart was active in many Georgetown causes, including preservation of the historic aspects of the area. She fought overdevelopment and pushed the work of the Citizens Association of Georgetown.

She remained active on the newspaper until about five years ago. The present editor is David Roffman, who joined her in 1968. He now has a staff of about 10 full-and part-time employees.

Mrs. Stewart is survived by a sister, Mary Crawford, of Silver Spring.
