Albert Einstein did not directly contribute to the development of the atomic bomb. However, his famous equation E=mc^2 laid the theoretical groundwork for understanding the energy released in nuclear reactions, which was crucial for the development of the atomic bomb by scientists like J. Robert Oppenheimer and others involved in the Manhattan Project.
