his series was one of several DC Comics based superhero cartoons that formed part of the 60-minute compilation program, The Superman/Aquaman Hour of Adventure. Only three, seven-minute episodes of The Atom were produced.

Atomic physicist Ray Palmer had the power to shrink from normal to microscopic size or anywhere in between. When evil threatened, he faced his adversaries in his dual identity as The Atom. As a member of Ivy University's science faculty, he always happened to be in the presence of fellow professors when danger struck and was therefore burdened with the additional task of keeping his alter ego secret. But no task was too big for the tiny Atom, and he overcame his opponents and the suspicions of his colleagues with equal success.

The Atom was also a member of the concurrent series, Justice League of America, and later appeared in The All-New Super Friends Hour and The Super Friends Hour.
