The Manuel and David Macias papers date from 1890 to 1972. They consist primarily of digital images scanned from three binders arranged by Pete Macias, Manuel Macias' son. The first binder focuses on Manuel Macias, and contains photographs of the Macias family, newspaper clippings, community newsletters, biographical information, and ephemera. Two binders illuminate the contribution of Rudolph "Rudy" Macias, another son of Manuel Macias, to World War II. Rudy Macias served as a scout in the 7th Cavalry and 1st Cavalry in the Pacific and Asiatic Theaters and was one of the last of the horse-mounted soldiers to serve in the military. The binders include photographs of Rudy Macias on horseback and telegrams home to his parents in Iowa. The fourth and final binder focuses on the musical career of Pete Macias. Plays and music written by Manuel Macias throughout his life, as well as a small number of newsletters produced by the Muscatine council of the Midwest La Raza Unida, complete the collection. The full extent of the Manuel and David Macias collection is preserved in the Iowa Digital Library.
