San Juan is the birthplace of artists and musicians who have significantly influenced Puerto Rican culture. During the 20th century, the musical aspect of the city was influenced by performers including Afro-Caribbean dancer and choreographer Sylvia del Villard and José Enrique Pedreira who became a composer of Puerto Rican ''Danzas''. International musicians such as opera singer Justino Díaz and Grammy Award winners Ramón Ayala (Daddy Yankee) and Ricky Martin were born in the city. Other notable residents include writers Giannina Braschi and Tomas Blanco, award-winning actors Raul Julia and Benicio del Toro, and comedian José Miguel Agrelot. Rafael Cordero (1790–1868), was influential in the development of Puerto Rican education and has been once renowned as "The Father of Public Education in Puerto Rico".
