Final answer:
Albert Einstein, a German-born scientist, was important in the development of the Atomic Bomb due to his foundational work in modern nuclear physics.
Step-by-step explanation:
The German-born scientist who was important in the development of the Atomic Bomb was Albert Einstein. Although Einstein did not directly contribute to the development of the bomb, his groundbreaking theories in physics, particularly the theory of relativity, laid the foundation for modern nuclear physics. Einstein's famous equation, E=mc², unlocked the understanding of the immense energy contained in atomic nuclei and provided the scientific basis for the development of atomic weapons.
