Lewis Lichtenstein Strauss was an American government official, businessman, philanthropist and naval officer. He was one of the original members of the United States Atomic Energy Commission (AEC) in 1946 and he served as the commission's chair in the 1950s. Strauss was a major figure in the development of nuclear weapons after World War II, nuclear energy policy and nuclear power in the United States.

The United States Atomic Energy Commission (AEC) was an agency of the United States government established after World War II by the U.S. Congress to foster and control the peacetime development of atomic science and technology. President Harry S. Truman signed the McMahon/Atomic Energy Act on August 1, 1946, transferring the control of atomic energy from military to civilian hands, effective on January 1, 1947. This shift gave the members of the AEC complete control of the plants, laboratories, equipment, and personnel assembled during the war to produce the atomic bomb.
