Sam Apple's biography of Otto Warburg reveals a Jewish scientist who defied the Nazis

Sam Apple's biography 'Der Kaiser von Dahlem' explores the life of Otto Warburg, a Nobel Prize-winning biochemist who was Jewish and homosexual yet remained in Nazi Germany as a leading cancer researcher. Warburg, who won the Nobel Prize in 1931, refused to comply with Nazi policies, banning the swastika and Hitler salute at his institute and protecting Jewish staff. Protected by Hitler due to his research value, Warburg was allowed to work until the war's end. Apple's book delves into Warburg's complex character, his privileged life in Dahlem, and his controversial decision to stay in Germany, offering insights into the scientific community of the early 20th century.
