In December, the DeGolyer Library was the recipient of another generous donation from Elmer and Diane Powell in addition to the thousands of items donated in 2014! Of great historical importance in the study of the Mexican Revolution, the Powell Collection includes many rare materials: real photographic postcards, photographs, prints, original artwork, broadsides, currency, periodicals, books and manuscripts related to the Mexican Revolution. The Powell collection covers the pre-revolution years of president Porfirio Diaz to the post-revolution era in Mexico. Particularly strong in photography, included are images related to such Federal and revolutionary leaders as Diaz, Madero, Huerta, Carranza, Obregon, Villa, and Zapata. There are many pictures by important but little-known photographers of battle sites, executions, street scenes, the Decena Tragica, and locations throughout Mexico and on the U.S. border during the ten year conflict.
