Well, I haven't been able to find out for certain who the first African-American brother in the fraternity was, but I *have* been able to verify that there was at least one African American brother in the Fraternity *prior* to the chartering of the first chapter at an HBCU.
Delta Eta chapter at Oregon State University which chartered June 9, 1946 included William Tebeau would would be Oregon State's first male African-American graduate among its charterers.
Delta Phi chapter at Johnson C. Smith University chartered April 17, 1947.
