Joseph Carter Corbin: Arkansas's "Profound Mathematician''

This is a historical article on J. C. Corbin, a nineteenth century mathematician and the founding president of the Historically Black University of Arkansas at Pine Bluff. This version omits the figures that appeared in the published edition. It also includes a lengthier bibliography and a new section ("Added after publication") which addresses some historical points. Updated the section "Added after publication" in response to feedback from Dr. Gladys Turner Finney.
