Prudence B. Saur (b. Belden) (c. 1838-1918) was born and died in Amherst, Ohio. Saur attended Oberlin College in 1857 and married John C. Saur, a businessman and druggist, in Fremont, Ohio, in 1864. She graduated from the Woman's Medical College of Pennsylvania in 1871 and worked as a physician in Chicago, Illinois. Saur studied Christian Science with Bradford Sherman, a student of Mary Baker Eddy, and then taught her cousin, Antoinette "Nettie" P. Belden, in May 1886. Sherman later heard that Saur did not accept statements in Christian Science as taught by Eddy or her students. Around 1886, the Saurs divorced, however Prudence kept using the last name professionally for the rest of her life. In 1895, she married Warren Wilkie, a professor, in Milwaukee, Wisconsin. Saur was also an author and known for her books Maternity: a book for every wife and mother (1889) and Our mothers' guide book: a manual of health, beauty and happiness (1896).
