He Fought for Civil Rights
During his time as president of Kappa Sigma, Prentiss Willson made waves at the Occidental College campus. One wave in particular was when a black student, Greg Gigsby, wanted to join the national fraternity union and was denied solely based on the color of his skin. Unable to accept such blatant racism, Willson fought for Kappa Sigma to quit the national fraternity union and become an independent chapter— which they did. Greg Gigsby was allowed into Kappa Sigma shortly after.
