Frank Stephens (naturalist)

Frank Stephens (1849–1937) was an American naturalist and the first director of the San Diego Natural History Museum. He was considered the pioneer naturalist of the Southwest, studying the mammals and birds of California, Arizona, and Baja California. His personal specimen collection of 2,000 birds and mammals, donated in 1910, was the foundation of the San Diego Natural History Museum's Birds & Mammals Department, now a major resource on bird and mammal species of western North America, including Baja California.
