Tremayne Hubbard, Dyess African-American Heritage committee president, unveil a historical marker Feb. 22, 2016, at Dyess Elementary in Abilene, Texas. In January 2015, Hubbard started researching integration in the Abilene Independent School District and applied for a historical marker to be placed at the elementary since it was the first school in Abilene ISD to become racially integrated in 1963.
