René Marqués
He wrote theater plays, short stories, and essays.   His most famous play is "The Oxcart (1956)" or "La Carreta" (which means "The Wagon"). It is the story of a Puerto Rican family who move from Puerto Rican countryside to New York City for a better life. The family has a hard time becoming like their neighbors. They go back home to live on a farm in Puerto Rico, but they find it is hard to go back to the way they were.
