Join author and photo historian Richard Cahan as he discusses his new book Un-American: The Incarceration of Japanese Americans During World War II. In 1942, the United States sent 109,000 residents of Japanese ancestry to live in detention centers for the duration of WWII and hired famed photographers Dorothea Lange, Ansel Adams, and others to document the expulsion. Cahan's book—coauthored with Michael Williams—showcases 170 of these never-before-seen photographs, many of which were impounded by the U.S. Army.  Combined with primary source government documents and firsthand recollections of Japanese American survivors, Un-American was described by Booklist as "an intensely revelatory and profoundly resonant book of beauty and strength, history and caution."
