Raul Cuadra Chamberlain (1924–1974) was a Nicaraguan musician and advertising pioneer.
In the 1940s, he traveled through Nicaragua and the rest of Central America with his orchestra, El Champu de Carino.
To contribute to the expense of traveling, he started to advertise various products and services of different businesses during the intermissions of Champu de Carino shows.
In 1950, he founded one of the first advertising agencies in the country - Publicidad Cuadra Chamberlain,[2] just as Nicaragua was experiencing a post World War II economic boom.
