By the mid-1950s, Justice Reed was dissenting more and more frequently from court rulings. His first full dissent had come in 1939, nearly a year after his tenure on the court began. Initially, his dissents "were only when, with Hughes, Brandeis, Stone or Roberts—like himself, lawyers of deep experience—he could not go along with what he considered the judge-made amendments of the Constitution implicit in the opinions of Hugo Black, Felix Frankfurter, William O. Douglas and Frank Murphy, whom Roosevelt had sent to follow Black and Reed on the court." But by 1955, Reed was dissenting much more frequently. Reed began to feel that the Court's jurisprudential center had shifted too far away from him and that he was losing his effectiveness.
