James Wesley Silver (June 28, 1907–July 25, 1988) was an American historian and professor. He taught at the University of Mississippi, later at the University of Notre Dame, and then at the University of South Florida.
He is best remembered for Mississippi: The Closed Society, a forceful study of segregation and power in Mississippi. His public support for civil rights, including during the conflict over James Meredith's enrollment at Ole Miss, made him a controversial figure in the state.
Although your note says "b. 1890," the reliable source I found for this author gives a birth year of 1907. I could not confirm a suitable portrait image from the sources available here, so I have left that blank.
