- Frank Ewers was a Catholic physician in Ottowa, Illinois, who was concerned about patients who wished to limit their families but found the rhythm method unreliable. Learning about research into tests for sugar in the mucus of the uterus, Dr. Ewers imagined that this work might lead to a general test for ovulation. He and several Catholic laymen then founded Weston Laboratories, to market the product.
