Donald Hiss

Alger Hiss's younger brother, Donald Hiss was also alleged by Whittaker Chambers to have been a member of the Communist underground. Donald Hiss (shown here with his son Bosley) denied the charges before HUAC and later testified for the defense at both trials. He was never indicted or prosecuted for asserting his own or his brother's innocence. 

Donald Hiss, like his brother, was a New Dealer. He, too, served as a secretary to Oliver Wendell Holmes. During the New Deal, Donald Hiss served in both the Labor Department and the State Department. In later years, Hiss was a partner at Covington & Burling, the Washington D.C. law firm where Dean Acheson also became a partner after leaving the government.
