Lourdes Casal (1936–1981), award-winning poet, fiction writer, editor, social psychologist, and activist, contributed to the articulation of multiple interdisciplinary fields including Cuban studies, Latina/o, Latin American, black, and women’s studies, yet her work has not received the attention it deserves because she published different kinds of writing in two languages, each directed to disparate, sometimes conflicting or overlapping, audiences. Alternatively, it could be said that her writing addresses an emergent readership more visible today decades after her death, who see—as she did—the need for dialogue across disciplinary, linguistic, and political divisions. Although Casal has remained in print primarily in Latina/o literary anthologies, Casal made her living as a social scientist and a psychology professor, and she remained engaged with Cuba through editorial work and what scholars call today “publicly engaged scholarship.” Casal’s work exemplifies a transnational attention to both homeland (Cuba) and residence (New York) that has become a distinguishing quality of Latina/o literature. In 1978, Lourdes Casal defined herself in “Memories of a Black Cuban Childhood” as learning to assert herself as an “Hispanic Black” (p. 62). In an interview with Margaret Randall that prefaces translations of her poetry into English, she defines herself as a “Latina,” and she asserts her claim to speak as a Cuban, despite living outside the island. During the Cold War, this combination of identifiers constituted a paradox, which Casal asserted both against the mainstream of the Cuban exile community and against heteronormative cultural nationalisms. Casal’s bilingualism and skillful diplomacy provided her with the salvoconducto to weave across multiple borders, despite the walls that became almost impossible to scale after the United States broke off diplomatic relations with Cuba in 1961 and Cuba began relocating people to the Military Units to Aid Production (UMAP) camps in the mid-1960s. A queer feminist of African, Chinese, and European descent, Casal’s writings and editorial projects map the participation of a diverse group of Cuban exiles in the articulation of latinidad; yet even as she becomes legible in certain ways, she remains largely illegible, precisely because she ventured into uncharted, sometimes life-threatening, border spaces, in step with an unexpected ideological itinerary.
