Fred C. Allison (July 4, 1882 – August 2, 1974) was an American physicist. He developed a magneto-optic spectroscopy method that became known as the Allison magneto-optic method. He claimed to have discovered two new elements (later discredited) using this method. He taught at the Auburn University Physics Department for more than thirty years.
