Lydia C. Roberts Graduate and Traveling Fellowships
The Lydia C. Roberts Graduate and Traveling Fellowships were established in 1920 and limited to students born in Iowa and "of the Caucasian race". Needless to say, this doesn't go down as well as it (somehow) did in 1920, but it has taken the university until 2013 to begin the process of amending the fellowship's racial restriction.
