Born in Millersburg, Holmes County, Ohio, on the 14th of February, 1825, and there remained until he was about eighteen years of age, received his education in the common school, and afterward was initiated into the technique of farming. About 1843 he removed with his parents to Farmington, Iowa, where his education was finished in the common school. Our subject enlisted in the army July 4, 1817, as a private, but it was not long before he was promoted, and received the commission of Lieutenant. He was mustered out at Ft. Leavenworth. While our subject was residing in Farmington, Iowa, previous to his military life, he had studied medicine, and to these studies he returned, and remained until the opening of lectures at Rock Island, where he attended the course of 1848-49. He graduated in 1850 from medical college at Davenport, Iowa. Before beginning the practice of medicine Dr. Craig was united in marriage with Miss Susan M Dunning, upon the 28th of March, 1850. They removed to Van Buren County, Iowa, and settled upon a farm. In 1853 he removed to Keokuk, and entered into partnership with his former preceptor until the fall of 1855, when he gave up the practice of medicine. Upon retiring from his profession our subject removed to Council Bluffs and engaged in real-estate and mercantile transactions. Here he was appointed to fill a vacancy in the Sheriff's office. In 1867 our subject was elected by the Republican Party to the Legislature. He was in the session of 1867-68, which was one of the most important and exciting, because of the subject under discussion being the resuming of land grants and reletting of the land. The Legislature finally settled the matter by resuming the land and reletting it under additional conditions. Upon returning from the Legislature our subject went to Council Bluffs, and engaged in obtaining right of way, depot privileges, subscriptions, etc., for the St. Joseph & Council Bluffs Railroad Company. In 1872 he was elected Warden of the Iowa Penitentiary at Ft. Madison, and continued to hold the same for three terms. The term of our subject as Warden expired in the spring of 1878. He then purchased a farm in Fremont County, Iowa, and engaged in general farming, but also gave much thought and attention to the higher grades of stock, including horses, cattle and hogs. Dr. Craig's enthusiastic patriotism and military experiences lead him to a prominent position in the G. A. R., with which he is connected, he is also identified with the I. O. O. F., Knights of Pythias, and in the Masonic fraternity has taken the degree of a Knight Templar.
