A. W. Underwood, a 19th-century African-American, achieved minor celebrity status with the purported ability to set items ablaze. Magicians and scientists have suggested concealed pieces of phosphorus may have instead been responsible. The phosphorus could be readily ignited by breath or rubbing. Skeptical investigator Joe Nickell has written that Underwood may have used a "chemical-combustion technique, and still other means. Whatever the exact method — and the phosphorus trick might be the most likely — the possibilities of deception far outweigh any occult powers hinted at by Charles Fort or others."
