William Bernbach was an American advertising creative director. He was one of the three founders in 1949 of the international advertising agency Doyle Dane Bernbach (DDB). He directed many of the firm's breakthrough ad campaigns and had a lasting impact on the creative team structures now commonly used by ad agencies.

Juan Valdez is a fictional character who has appeared in advertisements for the National Federation of Coffee Growers of Colombia since 1958, representing a Colombian coffee farmer. The advertisements were designed by the Doyle Dane Bernbach ad agency, with the goal of distinguishing 100%-Colombian coffee from coffee blended with beans from other countries. He typically appears with his donkey Conchita, carrying sacks of harvested coffee beans. He has become an icon for Colombia as well as coffee in general, and Juan Valdez's iconic appearance is frequently mimicked or parodied in television and other media.
