23 Feb. 1832–2 Sept. 1902
Benbow's success in business continued for the next twenty years. Of greatest significance in his career between 1872 and 1892 was his role as civic leader and generous benefactor. As an alderman in the mid-1870s, he campaigned, against strong opposition, for graded schools both white and black and for a city market. When educators were struggling to establish the school that later became Bennett College for black women, he assisted with both money and leadership. Similarly, he rescued the white Greensboro Female College. During reconstruction of its fire-gutted main building, the work superintendent died in a fall, and a bank failure deprived the institution of most of its funds. Benbow immediately took charge of the work and paid all wages and bills.
Beginning in 1879, Benbow called for the establishment of a school to train young women as teachers in the public schools. Twelve years later a crusade led by Sidney M. Finger, Edwin A. Alderman, Charles D. McIver, and Benbow culminated in the establishment of the Normal and Industrial School for White Girls. In this instance and in that of the Agricultural and Mechanical College for Negroes, established the same year, 1891, Greensboro outbid other cities for the schools. Benbow was the acknowledged leader of both efforts. In launching his campaign, he made what his friends regarded as "the speech of his life." He rallied businessmen and other citizens to subscribe privately $30,000 for the Normal School and $8,000 for the A. & M. College, so that Greensboro would get these institutions even if the required bond issues failed to pass. This kind of support so pleased the people that their approval at the ballot box was almost unanimous.
From 1881, Benbow served as a trustee of the Quaker school that evolved into Guilford College, and in 1891 he was present at the establishment of the Greensboro Monthly Meeting of Friends. He was one of five incorporators of the Guilford Battleground Company. In politics he affiliated with the Republicans.
By 1892, Benbow's fortune was estimated at about half a million dollars. In addition to various other enterprises, he had invested in the North State Improvement Company, which undertook to build the Cape Fear and Yadkin Valley Railroad. Though the railroad did benefit Greensboro and the rest of its territory, the company was ruined by the financial panic of that time. The principal men, involved in a desperate move, decided to endorse notes individually, and this decision was their undoing. For ten years, Benbow defended himself against various lawsuits, most of which were eventually compromised, but the strain and his age took their toll. One consolation there was, nevertheless: he lived to supervise the building of a new Benbow House, to see his son operate it, and to reside there himself. It was altogether fitting that, when he died, the services were conducted at the new Benbow by two Friends ministers. Burial was at Greene Hill Cemetery.
Mary Elizabeth Scott, whom Benbow married on 30 Nov. 1857, had died five years earlier. Three of their children survived them: Charles D., who became closely associated with his father's business interests and who later played a part in the development of St. Petersburg, Fla.; Mrs. Mary B. Crawford; and Lily.
