He entered Washington College, Pa., and in 1822 commenced his theological studies under the direction of Rev. Benjamin Kurtz, Hagerstown, Md., and continued them under Rev. Dr. Lochiman. He was licensed to preach at Reading, Pa., in 1825, and served as itinerant missionary until Feb. 25, 1827, when he accepted a call from the united churches of Lewistown and vicinity. In 1829 he accepted a call from Hanover, where he labored for eight years. In December, 1837, he assumed charge of the Church at Lebanon, Pa., which he served with great fidelity until 1849, when he was prostrated by disease, which terminated his life, July 23, 1850. Mr. Ruthrauff was of a kind and genial nature; his preaching, which was in both German and English, was eminently practical and pungent. See Sprague, Annals of the Amer. Pulpit, 9, 175.
