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.
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.
