Heisenberg wasn’t Jewish.
"Soon after Hitler came to power, the regime began to dismiss Jews and political opponents from civil service positions, which included academic positions at all levels. During the same period, Nazi physicists, such as the Nobel-Prize-winning Johannes Stark, began an attack on modern theoretical physics, including relativity theory and quantum mechanics, calling it "Jewish physics." Heisenberg and other leaders of the physics profession attempted to oppose these developments, but without much long-term success. (emphasis added)"
If the Nazis listened to Heisenberg, they might have had an atom bomb before the Americans. With all the fantastic weapons the Nazis did make; e.g., Me262 (sparrow}, the buzz bomb, and the V2 weapon; etc. I am quite thankful the Germans' work on the atom bomb was not as sucessful.
