Initially, Einstein had few loyal supporters. It was difficult for other people, even his fellow colleagues to comprehend his theories. However, as more and more of his theories were proven and understood, Einstein rose rapidly in position among the physics community.

It was only a matter of time before Einstein won the Nobel Prize in physics in 1922. He also acquired numerous other awards and honors from various scientific communities.

In 1939, Einstein together with various other prominent physicists wrote a letter to President Franklin D. Roosevelt, which pointed out the probability of creating an atomic bomb as well as the possibility that Germany was indeed embarking on such an enterprise. The letter with Einstein's signature did urge the United States of America to build the atomic bomb. Although Einstein played no role in the creation of the bomb himself and knew nothing about it, his insights on physics did made its creation possible. He greatly regretted this.
