Marvin Santiago (December 26, 1947 - October 6, 2004) was a Puerto Rican salsa singer who became famous all across Latin America during the 1970s. He was also a part-time comedian on Puerto Rican television. His brother, Billiván Santiago, had some success in Puerto Rico as a plena singer. Santiago was born in San Juan. After residing in various neighborhoods in the city he moved to the Nemesio Canales public housing project in his youth; he was eventually nicknamed "El Grifo de Canales" ("The kinky-haired, fair-skinned-one of Nemesio Canales") by close friends and fans. He was diagnosed with type 1 diabetes at a young age. Santiago was groomed as a bolero singer (a genre he didn't feel comfortable with) and was a struggling salsa singer (at one time he sang with Rafael Cortijo) until 1971, when he joined Bobby Valentín, another type 1 diabetic, as a duo. Their first LP, "Rompecabezas", ("Puzzle") sold well, and their second LP, "Soy Boricua" ("I'm a Boricua") is considered by many to be a salsa classic and an informal patriotic anthem for Puerto Ricans. That album's title song and the Tite Curet Alonso-written "Pirata de la Mar" ("Pirate of the Seas"), both sung by Santiago, became major international hits.
