Barbara Betteridge was born in Santa Barbara, California in 1913, the year after The Calendar of the Soul was first published. She joined the Anthroposophical Society when she was twenty-one, and dedicated the rest of her life to Anthroposophy: serving as secretary to the Los Angeles branch of the Anthroposophical Society for many years; translating Rudolf Steiner's lectures and verse; and through free-lance writing, especially on the Soul Calendar and the Gemut.
