Dunbar, John B., son of the above, was born at Bellevue, in what is now the State of Nebraska, April 3, 1841. He received his early instruction from his father, after which he spent one year at the Hopkins Academy, Hadley, Mass., and graduated at Amherst College in 1864, after he had served as private, sergeant and lieutenant in a light artillery company for three and a half years. From 1869 to 1878 he was professor of Latin and Greek languages in Washburn College at Topeka, and in 1872-73 he assisted Father Gaillard of St. Mary's mission in the preparation of a Pottawatomie grammar and dictionary. Later he compiled a brief grammar and partial vocabulary of the Pawnee language, but it was never published. On Aug. 22, 1876, he married Miss Alida S. Cook, whose parents were at that time connected with Washburn College. After leaving Topeka Prof. Dunbar was connected with the public schools at Deposit and Brooklyn, N. Y., and Bloomfield, N. J., where he still resides. In early life he became interested in the French and Spanish explorations in the southwest, and his library is rich in books and manuscripts relating to this subject. In Jan., 1885, he was elected a corresponding member of the Kansas Historical Society, and among his contributions to that society may be mentioned a translation of a French manuscript bearing on the Bourgmont expedition; an account of the Villazur expedition of 1720; and a bibliography of early French and Spanish authorities on the Southwest. He has contributed to the Magazine of American History and other publications, and has aided such writers as Shea and Brinton, but the greater part of his work is still in manuscript form.
