Which of the following Physicists aided Nazi Germany in their production of a nuclear weapon?

Werner Heisenberg aided Nazi Germany in their production of a nuclear weapon due to his expertise and involvement in the German nuclear research project during World War II. Heisenberg, known for his contributions to quantum mechanics and the uncertainty principle, was appointed the head of the German nuclear research project, also known as the Uranverein. While Heisenberg did not ultimately succeed in developing a working nuclear weapon for Germany, his efforts and collaboration with the Nazi regime were aimed at achieving this goal during that time.
