From wikipedia:
Juan José Arreola Zúñiga (September 21, 1918 – December 3, 2001) was a Mexican writer and academic. He is considered Mexico’s premier experimental short story writer of the twentieth century. Arreola is recognized as one of the first Latin American writers to abandon realism; he uses elements of fantasy to underscore existentialist and absurdist ideas in his work. Although he is little known outside his native country, Arreola has served as the literary inspiration for a legion of Mexican writers who have sought to transform their country’s realistic literary tradition by introducing elements of magical realism, satire, and allegory. Alongside Jorge Luis Borges, he is considered one of the masters of the hybrid subgenre of the essay-story. He published only one novel, La feria (The Fair; 1963).
