Bernard worked as an iron-ore miner at the Spruce Mine from 1910 to 1916 or 1917. In 1916 or 1917, Bernard enlisted in the Army and served on the Mexican border. During World War I, he served as an Army corporal in the 125th Field Artillery. He then became a civilian employee in the Army and Navy Intelligence from 1917 to 1919. He served overseas fifteen months overseas. After leaving the armed forces and returning home, Bernard found himself blacklisted from the mines because of earlier efforts to unionize workers. Instead, he became a city fireman from 1920 to 1936.
Bernard met Josephine Dinois while working for naval intelligence in France. They married in 1928 and had at least one child, Marie. Bernard moved to Long Beach, Calif., where he lived until his death there on August 6, 1983.
Communism
Bernard's single congressional term is notable for his casting the sole vote against an arms embargo against Spain during the Spanish Civil War:
Minnesota Congressman John T. Bernard fought throughout his life for working people against strong opposition. His outspoken and uncompromising views led him, on his second day in office, to cast the single "no" vote in Congress against the Spanish arms embargo. Bernard's vote proved farsighted as the Spanish Civil War became, in many ways, a "dress rehearsal" for World War II.
Less known years later were his strong support for the Communist-backed Popular Front:
Bernard won election in the Farmer-Labor landslide of 1936... and quickly became the most enthusiastic and outspoken advocate of the Popular Front in Congress. Not even other Congressmen who sympathized with the Popular Front underlined their links to the Communist Party by inserting, as Bernard did, articles from the Communist Party's Daily Worker into the Congressional Record.
While in office, Bernard's personal secretary in Washington was Marion Bachrach, sister of John Abt, chief counsel of the Communist Party. Whittaker Chambers named both Bacharach and Abt among others as members of the Ware Group during his testimony under subpoena to HUAC on August 3, 1948. That testimony led to the Hiss Case during 1949 and Hiss' conviction in January 1950. Bernard also employed Herman Griffith on his congressional staff. Griffith was a leading Popular Front activist and self-announced CPUSA member. In 1952, Bernard testified under subpoena before HUAC. For most questions, he asserted his Fifth Amendment privilege. He also asserted his loyalty to America and willingness to defend it. In 1977, Bernard accepted membership in the Communist Party USA.
