California Institute of Numerical Research

L. Dow Balliett published a series of books from the turn of the twentieth century on what she called the vibration of numbers and of names, in the general New Thought idiom of the period, in which a name and a birth date were held to carry a character that could be read off. Her material was suggestive rather than systematic: it asserted correspondences without laying down a single procedure that two practitioners would follow identically.

The Institute, founded in California in 1931, is where the procedure was laid down. Juno Jordan, who had studied with Balliett, led it for decades, and its publications and courses fixed the elements that modern English language numerology now treats as given: the assignment of the numbers one to nine to the letters of the Latin alphabet in order, the rule that a total is reduced by adding its digits until a single figure remains, the exemption of the master numbers eleven and twenty-two from that reduction, and the standard set of readings calculated from a birth date and a birth name.

Those calculations, the life path from the date, the expression from the full name, the soul urge from its vowels and the personality from its consonants, are the ordinary furniture of numerology as it is taught and sold today, and they were standardised here rather than inherited from anywhere older.

The system the Institute standardised is almost always sold as the Pythagorean method, and the label is worth examining because it is doing a lot of work. The Pythagoreans held numerical doctrines and the ancient world did practise isopsephy in Greek and gematria in Hebrew, in which the letters of an alphabet already carried numeral values as part of the writing system itself. That is a genuine tradition with a real history.

What the Institute standardised is different in kind. It assigns one to nine to the twenty-six letters of the modern Latin alphabet in sequence, and applies that to names spelled in modern English orthography. Neither the alphabet, nor the orthography, nor the sequence has any connection to Pythagoras, and a name transliterated differently produces a different reading. The label attaches an ancient pedigree to an arrangement fixed in California in the twentieth century.

The Institute was a private teaching and publishing body. It set examinations for its own certificates, published its own textbooks, and had no external membership requirement, peer review or independent testing of any kind, and no controlled study of its claims was ever undertaken by anyone outside it. Underwood Dudley's survey of numerological systems examines the arithmetic and the claims made for it directly. What survives today is not the Institute but its table, which is now the default in the popular literature.
