Charles Bierstadt (1819 - 1903), brother of renowned landscape painter Albert Bierstadt and commercial photographer Edward Bierstadt, traveled extensively across California and the American West in the early 1870s. Drawing upon the same keen eye for dramatic scale, light, and composition that made his brother Albert world-famous, Charles’ stereo views of Yosemite helped define the sublime visual iconography of the Valley for an eager East Coast and international public.
