A University of Texas historian devoted to keeping alive the stories of long-dead victims of racial violence along the Texas-Mexico border is among this year's MacArthur fellows and recipients of "genius grants." The Chicago-based John D. and Catherine T. MacArthur Foundation on Tuesday announced the 25 recipients, who will each receive $625,000. UT's Monica Muñoz Martinez is part of an eclectic group of grant winners this year that includes scientists, economists, poets and filmmakers.
