Louis Thomas McFadden (July 25, 1876 – October 1, 1936) was a Republican member of the United States House of Representatives from Pennsylvania, serving from 1915 to 1935.

[3] McFadden later became a "vociferous foe of the Federal Reserve",[4] which he claimed was created and operated by Jewish banking interests who conspired to economically control the United States.

After the expulsion from Washington, D.C., of the veteran petitioners of the Bonus Army, which he called "the greatest crime in modern history", McFadden moved to impeach President Herbert Hoover in 1932,[8] and he also introduced a resolution bringing conspiracy charges against the Board of Governors of the Federal Reserve.

"[4][9] The Central Press Association reported that he was "virtually read out of his party ... [had] his committee posts ... taken away from him…was ostracized by Republicans [and] called crazy ...".

[12] In 1934, he made several anti-Semitic comments from the floor of the House and in newsletters to his constituents wherein he cited the Protocols of the Elders of Zion, claimed the Roosevelt administration was controlled by Jews, and objected to Henry Morgenthau Jr., who was Jewish, becoming Secretary of the Treasury.

[13][14][15][16][17] Drew Pearson claimed in his "Washington Merry-Go-Round" column that, in a publication by the American fascist Silver Shirts, McFadden had been "extensively" quoted "in support of Adolf Hitler".

He was in New York City visiting with his wife and son in late September 1936, when he was taken ill at his hotel and died of coronary thrombosis[26][27] shortly thereafter in the Hospital for Ruptured and Crippled, in Manhattan.
