Federico Wulff was a German-American engineer born in San Antonio and educated in Hanover, Germany. He lived and worked in Torreon, Coahuila, for most of his adult life, serving for part of that time as the German consul. He moved to Torreon in the 1890s with his family (who also lived for a time in San Antonio) and experienced the disruption of the Mexican Revolution. The photo collection contains photographs of his family that included several small children; street scenes and dam construction in Coahuila; events from the Mexican Revolution in and around Torreon; and some images from San Antonio and El Paso. The collection consists of negatives and prints from the early twentieth century, including some glass plate negatives--some stereo images or panoramic photographs. Collection was donated by his daughter Tulitas Jamieson, who wrote an autobiographical memoir, Tulitas of Torreon.
