Louis B. Livingston chronicles the relationship between Theodore Roosevelt and the Marquis de Mores during their time together as cattle ranchers in the Dakota Badlands. Livingston focuses on the controversy as to whether the two seriously contemplated a duel to settle their differences, and he charts their divergent paths once they left the West after the ruin of their ranches. Livingston details de Mores’s obsession with antisemitism which he argues helped precipitate the notorious Dreyfus Affair in France, and he documents Roosevelt’s outspoken opposition to antisemitism during his political career.

Six photographs supplement the article, including two of de Mores and three of Roosevelt during their ranching years. A text box with the mission statement of the Theodore Roosevelt Association appears at the end of the article.
