The United States Atomic Energy Commission (AEC) was an agency of the
United States government established after World War ll by Congress for the
peace time development and control of atomic science and technology. It began
when President Harry S.Truman signed the McMahon/Atomic Energy Act (above)
on August 1, 1946, transferring control of atomic energy from military to civilian
control, to be effective on January 1, 1947. President Truman appointed David
Lilienthal (below) as the first Chairman of the AEC. The AEC was reassigned into
two new agencies in 1974, the Energy Research and Development Administration
and the Nuclear Regulatory Commission.

The Sonny & Cher Comedy Hour was a variety show based on the married
couple of pop-singer Cher and her husband, Sonny Bono. The show ran on
CBS when it premiered on August 1, 1971. It was canceled May 29, 1974,
due to the couple’s divorce, though the duo would reunite in 1976 for the
identically-formatted The Sonny & Cher Show (a title sporadically used
during the run of the Comedy Hour), which ran until 1977. The show, which
consisted of comedy skits mixed in with musical numbers, was a Top 20 hit
in the ratings for its entire run.
