Arthur Preuss (1871–1934) was a German-American journalist, editor and writer. He is noted for editing the Fortnightly Review and for opposing Freemasonry, Marxism, and eugenics. He was a conservative intellectual whose father, Eduard Friedrich Reinhold Preuss, had also edited a Catholic newspaper.^[1]

Preuss was a layman in St Louis. His Fortnightly Review was a major conservative voice in English and read closely by church leaders and intellectuals from 1894 to 1934. He also edited Amerika, a Catholic newspaper in St. Louis, serving also as managing editor. Amerika was published without interruption in St. Louis, in German, from 1872 until 1921; at the time of closing, it had a circulation of 25,000 copies. Preuss had succeeded his father Edward as editor.^[2]

Intensely loyal to the Vatican, Preuss upheld the German Catholic community, denounced the heresy of Americanism, promoted the Catholic University of America, and anguished over anti-German sentiment during World War I. He provided lengthy commentary regarding the National Catholic Welfare Conference, the anti-Catholic factor in the presidential campaign of 1928, the hardships of the Great Depression, and the liberalism of the New Deal.^[3][4]
