Wilbert Helde Timmons was born in 1915 in Springfield, Missouri. After serving in the United States Navy as an officer during World War II, he attended The University of Texas at Austin, where he received a Ph. D. in Latin American History in 1949. That same year, W.H. Timmons arrived in El Paso to teach history at Texas Western College, now the University of Texas at El Paso (UTEP). During his years at the university, Dr. Timmons was an avid researcher and writer on Mexican and Texan history, particularly El Paso history. He published many articles and scholarly works, as well as several books, including Morelos of México, Tadeo Ortiz, Mexican Colonizer and Reformer. His most popular and well-known work is El Paso: A Borderlands History. The Wilbert H. Timmons papers (1584-1992, bulk 1949 – 1990) are composed primarily of the research papers used by Dr. Timmons during his decades of study of the El Paso, Texas and Ciudad Juarez, Chihuahua area. These documents include photocopies and photostats of published material, maps, transparencies, transcriptions of letters, official documents, oral histories, newspaper clippings, student papers, theses, computer disks, and photographs. The collection is organized into six series.
