The heroism of D-Day is immortalized in history books, but far less attention is given to the individuals who worked undercover to prevent Germany from developing an atomic bomb during WWII. In his new book, The Bastard Brigade: The True Story of the Renegade Scientists and Spies Who Sabotaged the Nazi Atomic Bomb, science writer Sam Kean tells the stories of the men and women who made up the Alsos Mission, or the “Bastard Brigade.” They worked tirelessly to make sure Germany’s (impressive) scientific discoveries wouldn’t change the course of the war.
