Teófilo Villavicencio Marxuach [note 1] (October 2, 1912 – February 29, 1992) was a pioneer in Puerto Rican radio broadcasting.
Joaquín Agusty Ramírez, Rafael Quiñones Vidal, and Villavicencio are considered (in that order) the three most important Puerto Rican pioneers of radio broadcasting.
He was the official on air voice of the informational and entertainment programs sponsored by the West Indies Advertising Company, his programs served as the permanent radio home of popular local orchestras such as those headed by the Brothers Morales, Mario Dumont, Rafael Petitón Guzmán, and Carmelo Díaz Soler.
He was also host on various occasions to native artists such as Arturo Somohano, Emilio Bouret, Daniel Capa, Arturo Cortés, Lolita Cuevas, Alfonso López Prado, Ernestico Mantilla, Armando Ríos Araujo, Rafael Seijo, Lolita Traviso and Germán Vázquez, as well as to international stars (including Pedro Vargas, Hugo del Carril, the Argentine Paulina Singerman, and Carlos Gardel).
Villavicencio Marxuach was a member of the Puerto Rican Independence Party and a follower of independence advocates Pedro Albizu Campos and Luis Lloréns Torres, an interest which resulted in the 1977 publication of Luis Lloréns Torres, maestro en lo sencillo.
