But Perez y Martina — which tells the tale of a romance between a cockroach and a mouse — isn't just any children's story. When it was published in 1932, it was the first Spanish language book for children published by a mainstream U.S. press. And its author, Pura Belpré, was the first Puerto Rican librarian in New York's public library system at a time when the city's Puerto Rican population was swelling. Belpré could not find any books for kids in Spanish — so she wrote them herself.
Back in 1921, Belpré was a college student at the University of Puerto Rico.
