Abraham "Abe" Fortas was a U.S. Supreme Court associate justice from 1965 to 1969. Originally from Tennessee, Fortas became a law professor at Yale, and subsequently advised the Securities and Exchange Commission. He then worked at the Interior Department under Franklin D. Roosevelt, and subsequently Harry Truman appointed him to delegations that helped set up the United Nations. Later, in private practice, Fortas represented Lyndon Johnson in the hotly contested 1948 Democratic Senatorial Second Primary electoral dispute, and formed close ties with the president-to-be. Fortas also represented Clarence Earl Gideon before the U.S. Supreme Court, in a case involving the right to counsel. As a Johnson appointee to the Court, Fortas maintained a close working relationship with the president, and in 1968 Johnson tried to elevate Fortas to the position of Chief Justice, but that nomination faced a filibuster due at least in part to ethics problems that later caused him to step down from the Court. Fortas returned to private practice, sometimes appearing before the judges with whom he had served.
