Cremer established the International Arbitration League in 1870. He initiated an arbitration treaty between Great Britain and the USA. Cremer organized and promoted inter-parliamentary peace conferences, and he was editor of the journal "The Arbitrator". He was the only labor leader in the peace movement and he promoted brotherhood between the working classes in England and France.
Cremer was also one of the founders of the Inter-Parliamentary Union.
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.
Cremer and Suttner were the nominators' primary choice, but as an alternative they suggested a divided prize between Gobat and Ducommun. Beckman submitted a nomination in which he suggested Cremer as his primary choice.
The nominators included Hedin, Wavrinsky, Beckman, Hedlund and Elowson.
