Harold Buchman was a 20th-Century American Communist attorney, "the most important communist member" of the Progressive Citizens of America (founded by former vice president Henry A. Wallace, president of the Roosevelt Democratic Party Club, and treasurer for the Screen Writers Guild.
His name appeared in the earliest Hollywood blacklist: a list of Communist sympathizers along with Dalton Trumbo, Maurice Rapf, Lester Cole, Howard Koch, John Wexley, Ring Lardner Jr., Harold Salemson, Henry Meyers, Theodore Strauss, and John Howard Lawson.
In January 1948, Buchman announced the Wallace for President Committee. In February 1948, he became new executive secretary and Maryland state director of the Progressive Party. In Summer 1948, when the Maryland attorney general rejected all filings by Progressive candidates for failure to sign loyalty oaths, Buch announced he would file a suit.
In June-July 1951, Buchman counseled the follow out of more than 40 people subpoena-ed by HUAC: Joseph Henderson and Philip Gran (June 21, 1951), Robert W. Lee (June 26, 1951), Irving Kandel (June 27, 1951), Sam Fox and Howard Bernard Silverberg (June 28, 1951), Louis Julius Shub (July 12, 1951), and Milton Seif and Irving Winker (July 13, 1951).
In March 1952, Buchman defended: Maurice Braverman, George Meyers, Roy Wood, Dorothy Rose Blumberg (wife of Albert Blumberg), Philip Frankfeld, and Regina Frankfeld (all members of the Communist Party branch of Maryland and the District of Columbia).
In 1971, Buchman defended Arthur F. Turco, Jr., a New York lawyer charged in connection with the 1969 torture and murder of a suspected Black Panthers police informer.
