Andrés Antonio ("Tony") Ramos Mattei (5 November 1941 – 11 February 1988) was a Puerto Rican sugar industry historian. He is considered the "undisputed authority" on the subject of Puerto Rico's sugar industry. Early life Ramos Mattei was born in Ponce, Puerto Rico, in 1941. Career Ramos Mattei is considered by his professional peers "a major figure in the world of sugar history...one of its most skillful and accomplished craftsmen...a force among historians of Puerto Rico and the Caribbean, and a scholar of stature among students of the sugar industry". Ramos Mattei's career was a multifaceted one, as were his scholarly writings. A student of Puerto Rico in general, he approached insular issues in the broadest possible perspective. His work was often explicitly comparative but with a regional, Caribbean-wide twist in its implications. He was an active member of the Association of Caribbean Historians, where he was instrumental in establishing fruitful interaction between his fellow historians in Puerto Rico and those of other Caribbean nations. Political interests Ramos Mattei's intellectual passion revolved around the peculiar historical processes of his native Puerto Rican society where he wrote about its enduring and perplexing colonial drama. In this regard, he was most interested in the life and thought of Ramon Emeterio Betances, the Puerto Rican abolitionist, revolutionary, and "father of the Puerto Rican nation". Ramos' contributions in this field was almost as intense as his contributions to the history of the sugar cane industry. Works Ramos Mattei is best known for his work on the transition from the hacienda to the modern land-and-factory combination in Puerto Rico's sugar sector. His book titled "La hacienda azucarera" is a landmark study, based on an investigation into the Serralles plantation archives in Ponce.
