Stevie Ruiz, a professor at California State University, Northridge, has published a book examining how immigrant labor shaped the environment of the American West. The work details the historical contributions of figures like chef Tie Sing in the development of the National Park Service.
Why it matters
The book reframes the history of the American West by documenting how immigrant communities managed the land and facilitated early conservation efforts. It highlights the essential role of marginalized groups in establishing the region's public lands.
During the late 1800s, Tie Sing provided fine dining for U.S. Geological Survey expeditions in Yosemite. This logistical feat supported the surveyors who eventually lobbied Congress to establish the National Park Service.
