Sweatt v. Painter. Sweatt v. Painter, 339 U.S. 629 (1950), was a U.S. Supreme Court case that successfully challenged the separate but equal doctrine of racial segregation established by the 1896 case Plessy v. Ferguson. The case was influential in the landmark case of Brown v. Board of Education four years later. The case involved a black man, Heman Marion Sweatt, who was refused admission to the School of Law of the University of Texas, whose president was Theophilus Painter, on the grounds that the Texas State Constitution prohibited integrated education.
