Bio: Katherine Burton (born Katherine Kurz, circa March 1890, near Cleveland, Ohio) was an American Roman Catholic convert who became renowned in her post-conversion years as a religious biographer. She was also a prominent social activist campaigning for family rights, a poet and a short story writer.

Burton was, even before her conversion, interested in the problems women faced with large families, and even before it become the only method of birth control approved by the Church, she was a developer and advocate of the rhythm method of contraception, having known about the fertile and infertile periods of the menstrual cycle ever since her days at college during the 1900s. She also believed that most Roman Catholic writers of her time were stylistically flawed because they were "too arrogant and preachy", with the result that she wrote biographies that read more like fiction.
