Of all the changes that the university experienced in the past 75 years, none have been as significant as desegregation. A. Tennyson Miller, a black educator from Port Arthur, entered graduate school in 1954. In June 1955, Joe L. Atkins of Dallas applied for admission as an undergraduate student. He was refused entrance and brought a suit in the United States District Court, Fifth Circuit. During the time the suit was pending Mr. Atkins began his studies at another institution. Mrs. I. E. L. Sephas of Fort Worth became the first African American undergraduate when she enrolled in February 1956. By summer more than fifty African Americans were enrolled.
