Erwin Kempton Mapes (9 June 1884 – 18 February 1961) was an American scholar of Spanish-American literature and Hispanist, renowned for his work on the Hispanic Modernists.
Born in Gilman, Illinois, Mapes received his bachelors from Cornell College in Mount Vernon, Iowa, in 1909.
He then went to Harvard University and studied Hispanic Studies under Jeremiah D.
He was for many years considered the highest authority in these subjects.
Almost all of his work was published in American and French journals.
He also published a few textbooks, such as Y va de cuento (1943), in collaboration with Juan LĂłpez-Morillas (who married his daughter Frances, who would become an important Spanish-English translator).
