Alfred Lewis Levitt

 was a writer on Bewitched. He and his wife, Helen Slote Levitt, co-wrote the fourth season episode, Samantha's Thanksgiving to Remember (1967). He was credited as Tom August.

Levitt was blacklisted for his involvement with the Communist Party by the House Un-American Activities Committee in 1951, but was not charged with any crime. The subpoena was so damaging to his career, however, that he used an assumed name, Tom August, for almost twenty years after his hearing. Later, he led the effort to restore blacklisted writers' original names to film credits.
