Fernando Ortiz is recognized today as one of the most influential Latin American authors of the 20th century. Amazingly prolific, his publications written between the 1890s and the mid-1950s engage with a vast array of subjects and disciplines. Perhaps Ortiz’s most significant accomplishments were the creation of the field of Afro-Cuban studies and major early contributions to the emergent field of Afro-diasporic studies. Almost everyone else associated with similar research began their investigations decades after Ortiz and in dialogue with his work. Ortiz was one of the first to seriously examine slave and post-abolition black cultures in Cuba. His studies became central to new and more positive discourses surrounding African-derived expression in the mid-20th century that embraced it as national expression for the first time in Latin America. This essay considers Ortiz’s academic career and legacy as regards Afro-Cuban musical study beginning in the early 20th century (when his views were quite dated, even racist) and gradual, progressive changes in his attitudes. Ortiz’s work on music and dance have been underrepresented in existing academic literature, despite the fact that most of his late publications focus on such topics and are considered among his most valuable works. His writings on black heritage provide insight into the struggles within New World societies to overcome the racial/evolutionist ideologies that justified colonial subjugation. His scholarship resonates with broader debates throughout the Americas over the meanings of racial pluralism and the legacy of slavery. And his changing views over the years outline the trajectory of modern Western thought as regards Africa and race, specifically the contributions of Afro-diasporic peoples, histories, and cultures to New World societies.
