Abstract：
:This brief celebration of the work of Francisco Guerra (1916-2011) highlights his role as mentor for an international community, his study of local events in the context of global developments, and his contributions to the understanding of the medical history of Puerto Rico. A selective review of Francisco Guerra's methods and publications shows that his principal works are characterized by their vast scope and exhaustive coverage of ancient and modern published sources, coupled with clarity and conciseness of exposition. At least eight of his books (presented here) provide important information on events and personalities in Puerto Rico up to about 1940. Guerra, through his clinical experience, profound scholarship, and personal contacts, recovered the local medical developments of peripheral areas and incorporated them to a global context.
