David Rein

In March 1938, like his friend Forer, Rein began work for the National Labor Relations Board (NLRB) through late 1941 or early 1942. After spending a few months in the Office of Price Administration, he joined the United States Marine Corps at yearend 1942 and served through October 1945, when he returned to the NLRB.[2]

In mid-year 1946, David Rein joined Joseph Forer as private practice law partners in Washington, DC. Together, they "represented more than 100 persons who had been termed 'unfriendly' witnesses by the House Committee on Un-American Activities, the Senate Internal Security Subcommittee of the Senate subcommittee headed by the late senator Joseph McCarthy."[5]

As historian Joan Quigley describes:

In the late 1940s, while Congress and the executive branch trawled for evidence of disloyalty and subversion, Rein and Forer immersed themselves in difficult and disfavored causes: opposing the Mundt-Nixon Bill; defending labor unions and alleged Communists; upholding the Bill of Rights. Rein ... represented Gerhard Eisler ... As progressives and New Deal veterans, Forer and Rein also nurtured ties to the National Lawyers Guild, which HUAC had branded a Communist front in 1944.[6]

Attorney Victor Rabinowitz recalled in his memoir that Rein's circle of communist-supportive lawyers stretched to New York City (headquarters of the National Lawyers Guild). They included Harry Sacher, Abe Unger, David Freeman, Forer, and Rabinowitz himself, "all lawyers active in the representation of witnesses before congressional committees." He explained:

Unger and Freeman were attorneys for the (Communist) Party; Sacher had been lead defense in the prosecution of Communist party leaders under the Smith Act; I was a member of the Party and the others were close to it if not members. We certainly weren't making Party policy, but our views would have some influence on the Party and its members.[7]

In May 1949, Dr. Mary Church Terrell decided to take on the issue of desegregation head-on. She consulted Forer. Forer led the National Lawyers Guild's DC chapter in submitting an opinion in their favor. With such advice, Dr. Terrell and colleagues Clark F. King, Essie Thompson, and Arthur F. Elmer entered the segregated Thompson's Restaurant, next door to the offices of Forer and Rein's office at 711 14th Street NW, in Washington, DC, between H an G Streets cut by New York Avenue and across the street from the Trans-Lux Theatre. When refused service, Terrell & Co. sued.

Attorney Ringgold Hart, representing Thompson, argued on April 1, 1950, that District laws were unconstitutional. Regardless, Forer's research found that the U.S. Congress had jurisdiction over DC and so could overrule segregation; Charles H. Houston, dean of Howard University Law School concurred.

Supreme Court of the United States.

The case District of Columbia v. John R. Thompson Co. reached the U.S. Supreme Court. Forer and Rein argued the case. On June 8, 1953, the court ruled that segregated eating places in Washington, DC, were unconstitutional.[1]

The Washington Post recounted in 1985, "Four days after the Supreme Court ruled, Mary Terrell and the three other original complainants went back to Thompson's. Joe Forer followed them in. As he recalls the moment, the manager, himself, came over and personally, even obsequiously, carried Mary Terrell's tray to the table."[4][8][9][6]

As a civil liberties lawyer, Rein argued cases before the United States Supreme Court, including some major cases involving First Amendment rights, include:

• 1951: Joint Anti-Fascist Refugee Committee v. McGrath
• 1952: Harisiades v. Shaughnessy
• 1967: W.E.B. DuBois Clubs of America v. Clark
• 1976: Secretary of the Navy v. Avrech[3]

Forer & Rein represented communists including Gerhart Eisler and William Gropper.[1] They argued for the rights of striking workers, foreign-born aliens (with leftist leanings, e.g., Eisler), and servicemen. They won for the National Council for American-Soviet Friendship the right to contest in court its designation by the attorney general as a "subversive organization." They also represented members of the press on strike against the Washington Post in 1975.[1]

In 1955, Rein and his wife testified before HUAC but refused to answer questions as to communist affiliation.[1][2]

In 1977, a release of internal memos of the FBI revealed, according to the Washington Post, that:

An Oct. 4, 1951 memo to Hoover said that a search of trash at the Washington offices of guild lawyers Joseph Forer and David Rein had uncovered a draft resolution urging President Truman to authorize a citizens' investigation of the FBI because of its alleged excesses in loyalty checks.[10]

When Forer retired from practice with Rein in July 1978, Rein reformed the practice as Rein, Garfinkel & Dranitske.[1] Presently, the firm is Liotta, Dranitzke & Engel.[11][12]
