Suttner was the author of the novel "Die Waffen nieder" (Lay Down Your Arms), the most important antiwar novel of the period. She was the founder and president of the Austrian Peace Society (1891), and she contributed to the foundation of the Permanent International Peace Bureau (1891). Suttner was nominated for her contribution to the international peace movement.
Ducommun was the unpaid leader of the Permanent International Peace Bureau, and his work was therefore closely connected to it. He actively started working for peace in 1867 when he participated at the foundation of Ligue de la Paix et de la Liberté. Ducommun advocated a pragmatic and practical approach to peace work, and he promoted international arbitration.
