Rae B. Carl, 81, chairman of the board of Call Carl Inc., a Washington automboile towing and repair firm, died Friday at her home at Lauderdale-by-the Sea, Fla., following a stroke.

Mrs. Carl became chairman of the company in 1970 following the death in 1969 of her husband, Edmund O. Carl, who had founded the company.

Mrs. Carl, who maintained homes in Bethesda and Florida, was born in Washington. She graduated from old Business High School. She was the corporate secretary of Call Carl before becoming board chairman.

In addition to her business activities, Mrs. Carl was a member of the Lottie Hessick Circle of the Florence Crittenton Home, Lebanon Chapter No. 25 of the Order of the Eastern Star, the Ladies Auxiliary of the Metropolitan Police Voys Club, and Congressional Country Club.

She also had been a member of the old Central Presbyterian Church in Washington.

Survivors include a son, Edmund O. Jr., of Olney; a daugher, Ruth Irminger, of Lauderdale-by-the-Sea; two sisters, Katherine Morris of Olney, and Nettie Stringer, of Deale, Md,; nine grandchildren, and two great-grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to Heroes, Inc, 722 10th St. NW, Washington, 20001.
