Before the Deluge is a wonderful, compelling social history of Berlin between the wars. It explores the fascinating social, cultural, and scientific developments in Berlin as the political drama of Nazism plays out in the background. In these pages you will meet some of the 20th century's greatest politicians, artists, filmmakers, scientists, etc. who meet in the crossroads of Central Europe. Where else can you get Karajan, Einstein, Isherwood, Hitler, Weil, Garbo, and Lang in the same book........And, if you like this book, also try Olympia: Paris in the Age of Manet or City of Nets: A Portrait of Hollywood in the 1940's - both by Friedrich: both of them are equally good.
