Timothy Huebner, a professor of history at Rhodes College, speaks at the unveiling of the historical marker that now stands at the site of a slave market operated by Nathan Bedford Forrest in Memphis, on April 4, 2018. Huebner is a member of Calvary Episcopal Church. When he learned that the church's parking lot was once the site of the slave market, Huebner and his students began to research the slave trade in Memphis in order to create the historical marker.
