Antonio Pedreira's Insularismo

Four decades into American rule, a University of Puerto Rico professor sat down and asked a question the island had never really had to answer under Spain: with Taíno, African, and Spanish roots all folded into a new American colonial arrangement, what really makes someone Puerto Rican?

Dr. Antonio S. Pedreira was born in San Juan in 1899, the same year the Foraker Act took effect, a coincidence of dates that fits the arc of his work almost too neatly. In 1920 he studied medicine for a time at Columbia University in New York, where the racism he encountered there was one of several experiences that pushed him toward Puerto Rican nationalism.

He returned to the island, earned a Bachelor of Arts in 1925 and a Master of Arts in Letters in 1928 at the University of Puerto Rico, then a doctorate in Philosophy and Letters at the Central University of Madrid in 1932, giving him formal academic footing on both sides of the Atlantic.

Back home, he became a professor of Spanish literature and later director of the Department of Hispanic Studies at the University of Puerto Rico, while also writing a long-running column, "Aclaraciones y críticas," in the newspaper El Mundo.

In 1934 he published his most influential work, Insularismo, a wide-ranging study of what it meant to be Puerto Rican, tracing the interweaving of Spanish, Taíno, and African cultural roots and examining how Puerto Rican identity had survived the 1898 American invasion at all, a question few scholars had approached with such depth before him.

Pedreira died of pneumonia on October 23, 1939 in San Juan, barely five years after Insularismo's publication. His work anchored what is often called the "Generation of 1930," a generation of Puerto Rican writers wrestling in print with exactly the identity questions his book had raised, under a U.S. rule that showed no signs of ending soon.
