  • in "J.N. Warren", in Northwestern Iowa: Its History and Tradition, vol. 3:
    Dr. John Nelson Warren, one of the best known and most highly respected residents of Sioux City, where he has made his home during the past thirty-eight years, has been an active representative of the medical profession for fifty-six years and has specialized in surgery since 1892. His birth occurred in Dewitt, Iowa, on the 30th of April, 1846, his parents being Monroe and Betsey Ann Warren, the former born on a farm in the Western Reserve of Ohio. The father was of English descent, while the mother came of English and French lineage.
    John N. Warren acquired his early education as a public school pupil at the place of his nativity and during the year 1862 pursued academic studies in Mount Carroll Seminary of Mount Carroll, Illinois. He entered Cornell College at Mount Vernon, Iowa, for the session of 1863 and in March, 1864, enlisted for service in the Union army, becoming a member of Company F, Forty-fourth Iowa Infantry. Having determined upon the practice of medicine as a life work, he entered upon preparation therefore in the medical department of the University of Michigan, which he attended in 1869 and 1870, and on the 1st of March, 1871, he was graduated from the medical department of Miami University of Ohio.
    His initial experience in the field of his chosen profession was gained at Dewitt, Clinton county, Iowa, where he remained until March, 1878, when he moved to Storm Lake. It was on the 1st of November, 1889, that he took up his abode in Sioux City, Iowa, where he has resided continuously to the present time and where he has been accorded a practice of steadily growing volume and importance.
    As above indicated, he began specializing in surgery thirty-five years ago, and his success in this field of professional science has been pronounced. For a period covering more than a half century he has effectively utilized his knowledge to the best possible advantage in his efforts to alleviate suffering and check the ravages of disease, and he has long enjoyed an enviable reputation among his professional colleagues as well as the laity.
    On the 27th of June, 1877, at Lyndon, Illinois, Dr. Warren was united in marriage to Mary V. M. Hubbard, who was there born on the 3d of February, 1846. They became the parents of two sons and a daughter, namely: Dr. Alexis M. Warren, who married Beatrice Orton and resides at Bellingham, Washington; Nelson J. Warren, also living at Bellingham, Washington; and Mrs. R. M. Jordon, of Winside, Nebraska.
    Dr. Warren gives his political allegiance to the republican party, believing its principles most conducive to good government. In Masonry he has attained the thirty-second degree of the Scottish Rite, belonging to the lodge, chapter, commandery, consistory and Shrine. Though now an octogenarian, he is still an active factor in the world's work and may look back with justifiable pride upon a long, honorable and useful career.
