Studs Terkel, a master of the interview, talks with a wide variety of people and learns about their opinions and experiences regarding World War Two - how it affected the lives of those who lived or were born during that period of human history.
Studs Terkel's collection of interviews with various populations of the USA in The Good War is a good antidote to overromanticization of World War 2 conditions.
I've been reading Studs Terkel's The Good War, an oral history of WW2, and there are some incredible interviews with members of the Manhattan Project in it. At least at the beginning, they really thought Germany would beat them to the bomb.
