Carls wrote the preeminent book on the life of Louis Loucheur. Stephen Schuker of the University of Virginia called it "a superb biography of one of the most fascinating and forward-looking leaders of the Third Republic." "[Carls] offers a highly original and important contribution to the study of modernization in twentieth-century France." In this book called Louis Loucheur and the Shaping of Modern France Carls proposes that Loucheur, a World War I weapons manufacturer who turned to politics, was a first-generation technocrat and a major player in France’s postwar industrialization and modernization. An expanded version of the book was published in France under the title Louis Loucheur: Ingénieur, homme d’état, modernisateur de la France 1872-1931.
