"All in all, and in spite of the few criticisms mentioned above, it is hard not to be impressed by the depth of research and the precise presentation of facts and analysis contained in Maul's book. It certainly succeeds in its main aim of offering a comprehensive national and transnational case study of the complex interplay between fundraising and spiritual values, pacifism and militarism, and corporatism and idealism during the "humanitarian turn" (Aufbruch) of the first half of the twentieth century."
