Nella C. Manes, the former chief executive of Ehrlich-Manes Associates, a Washington advertising agency, died Dec. 10 at her home in Boca Raton, Fla. She was 93.
The cause was congestive heart failure, said a sister, Juanita Campitelli.
For more than 35 years, Mrs. Manes worked in advertising in Washington, beginning just after World War II as a buyer of broadcast time slots for Kal, Ehrlich & Merrick, where she eventually became vice president for media.
In 1968, she and Alvin Q. Ehrlich formed Ehrlich-Manes. By the late 1980s, Mrs. Manes was chief executive of the business, which had more than $40 million in annual billing and a staff of 60. She retired in the early 1990s and moved from Chevy Chase to Florida.
Nella Cellini was born in Steubenville, Ohio. She came to Washington in the early 1940s and was a procurement specialist with the Army Quartermaster Corps.
She chaired the membership committee of Friends of the National Zoo and was a member of the steering committee for communications of the Washington Board of Trade.
Her marriage to Robert Manes ended in divorce.
Survivors include a daughter, Michele Broadfoot of Boca Raton; four sisters; two brothers, two grandchildren; and four great-grandchildren.
