In 1954, St. Paul Hospital became the first in Dallas to give courtesy privileges to African-American physicians to practice in the hospital. African-Americans could not join the medical staff of St. Paul or any other Dallas hospital until the Texas Medical Association (TMA) voted in 1955 to admit them to membership, because membership in the Dallas County Medical Society (DCMS) was required, and DCMS members were required to be TMA members. The seated physician is Dr. Lee G. Pinkston. Standing, left to right, the physicians are: Dr. Frank H. Jordan, Dr. Joseph R. Williams, Dr. William H. Flowers, and Dr. George L. Shelton. In 1957, St. Paul admitted seven African-American physicians to the staff. Racial segregation of patients at St. Paul lasted until 1959.
