Modern numerology has various antecedents. Ruth A. Drayer's book, "Numerology, The Power in Numbers" says that around the start of the 20th century Mrs. L. Dow Balliett combined Pythagoras' work with Biblical reference. Balliett's student, Juno Jordan, helped numerology become the system known today as Pythagorean, although Pythagoras himself had nothing to do with the system, by publishing "The Romance in Your Name" in 1965, provided a system for identifying what he called key numerological influences in names and birth dates that remains used today. Other 'numerologists' including Florence Campbell (1931), Lynn Buess (1978), Mark Gruner (1979), Faith Javane and Dusty Bunker (1979), Kathleen Roquemore (1985) expanded on the use of numerology for assessing personality or events. These different schools of numerology give various methods for using numerology.
