Santiago Rafael Armada Suárez or Santiago Armada was a Cuban artist and designer. He was born in June 1937 in Palma Soriano in the current province of Santiago de Cuba and died in Havana in 1995. He was also known by the nickname Chago.
Armada entered the Havana Professional School of Business in 1954 where he studied bookkeeping. In May 1958 he created the cartoon character Julito 26, which later appeared in the El Cubano Libre newspaper. During the revolutionary insurrection he stood in the Sierra Maestra, while very young, and formed part of the José Martí Column 1.
Armada composed several songs that were aired on the then newly opened Radio Rebelde station.
In 1961 he co-founded the Union of Writers and Artists of Cuba (known by its acronym UNEAC) and in 1962 became a member of the Union of Journalists of Cuba (UPEC). He is considered, together with Servando Cabrera Moreno, Raul Martinez and Antonia Eiritz Humberto Peña, as a participant in the visual artistic avant garde of the 60's decade.
Armada published his first humorous comics in the Mercurio and Ahora magazines. While taking part in the 1950s revolutionary movement against Batista in the Sierra Maestra, he began working on the editorial staff of the clandestine newspaper, El Cubano Libre. He was responsible for the humour supplement of the newspaper. It was here that he first revealed the humorous comic character Julito 26 (in May, 1958). to the readership of El Cubano Libre. Later, after the 1959 revolution, Julito 26 began to be published in the Revolución magazine. 
In 1960 he founded the magazine, El Pitirre, which produced weekly humour. He also corroborated on other periodicals such as Bohemia and Palante.  In 1961 he created another cartoon figure, Salomón for La Revolución newspaper.
