What did Hitler’s rise to power mean for Americans working in 1930s Berlin? We’ll look back this hour to 1933 and the experiences of U.S. Ambassador to Germany William E. Dodd with bestselling nonfiction author Erik Larson, whose new book is “In the Garden of Beasts: Love, Terror, and an American Family in Hitler’s Berlin” (Crown, 2011). Larson will address the Dallas Museum of Art’s Arts & Letters Live series tonight.
