Mary Fabyan Windeatt lived from 1910-1979 and grew up in Saskatchewan, Canada. The Mount Saint Vincent College awarded her a Licentiate of Music degree when she was just seventeen, and she began writing Catholic works when she was about twenty-four. Later she sent one of her stories to a Catholic magazine, and after it was accepted, she continued to write. In total she composed at least twenty-one children's books, as well as periodical children's pages written for The Torch, a monthly Dominican magazine.

Mary Windeatt is most renowned for her many novels of the saints, which she wrote specifically for children, including lives on the Children of Fatima, Cure of Ars, St. Thomas Aquinas, St. Rose of Lima and many others. After living with her mother in St. Meinrad, Indiana, she died on the twentieth of November, 1979.
