Professor Thornton comes face-to-face with segregation, which he accepts passively but with hurt pride. On long trips he sometimes dodges the problem by taking a more expensive but un-segregated plane. His salary as a professor is $6,600 a year and he could live quite comfortably were it not for his determination to put his own three children through college. Because their ages are such that they can go through one at a time, he thinks he can do it.” Gordon Parks/Courtesy The Gordon Parks FoundationAirline Terminal, Atlanta, Georgia, 1956.
