LOST LA brings Southern California history to life by marrying archival materials from the L.A. as Subject research alliance with innovative forms of documentary storytelling. Hosted by public historian Nathan Masters of USC Libraries, each episode of LOST LA brings the primary sources of Los Angeles history to the screen in surprising new ways. Much of L.A.'s past is lost to history - but through the region's archives we can rediscover a forgotten L.A. that preceded the arrival of Anglo settlers and learn how it transformed so quickly into a sprawling, culturally diverse metropolis.
