Founding by Llewellyn George

Llewellyn George, a Welsh born astrologer who had emigrated to the United States in the late nineteenth century, founded his publishing company in Portland, Oregon in 1901, concentrating initially and almost exclusively on astrology in the form of instructional books and annual almanacs aimed at practicing and aspiring astrologers. George also founded the Portland School of Astrology alongside the press, giving the business a combined publishing and teaching identity from the start, and his 1910 book The A to Z Horoscope Maker and Delineator became one of the standard English language astrological reference works of the early twentieth century.

The Moon Sign Book, first issued in 1905 as an annual almanac keyed to lunar positions for gardening, weather prediction and other folk astrological purposes, became one of the company's best known and most durable publications, continuing publication annually for more than a century. George relocated the growing company from Portland to Los Angeles in 1920 to be closer to a larger astrological readership and community, and he continued to run it as a specialist astrological publisher until his death in 1954, after which the company briefly passed into the hands of a printing firm before being offered for sale.
