The shipping of Japanese-Americans to prison camps during World War II is not one of the prouder episodes in American history. But it is a well-documented episode.
Some of the best-known American photographers of the time, including Dorothea Lange and Ansel Adams, captured images of American citizens held captive in the name of security.
A new collection of the photographs is offered in the book Un-American. Photo historians Richard Cahan and Michael Williams assembled the collection. They visit to talk about the project, and some of the stunning images they curated.
