A Is for Atom is a 14-minute animated promotional documentary short made in 1953 by John Sutherland and sponsored by General Electric. It introduces viewers to the atom and to the way nuclear energy is released from certain kinds of atoms. A narrator, joined by the caricatured Dr. Atom (a character with an atom for a head), compares atomic structure to the Solar System and describes protons, neutrons and electrons. The film also covers the peacetime uses of nuclear power and the by-products of nuclear fission. It is now in the public domain and is Sutherland's most-decorated film, with numerous festival honors. It opened theatrically in Los Angeles on July 2, 1953, distributed free of charge by Al O. Bondy.
