Cornelia Ramondt-Hirschmann (29 July 1871 – 20 November 1957) was a Dutch teacher, feminist, pacifist and theosophist active in the first half of the twentieth century.

Along with Emily Greene Balch, Chrystal Macmillan, Rosika Schwimmer, and Julia Grace Wales, Ramondt-Hirschmann formed the group[2] speaking to peaceful nations.

In war, most diplomats refused to make definitive statements, and encouraged by this development, the group, without Schwimmer, who as a Hungarian could not enter Russia, made plans to go to Petrograd.

[5] After several days they managed to secure an interview with the Foreign Minister Sergei Sazonov, who despite his view that nothing would come of such a meeting, wrote a statement that Russia would not oppose a neutral mediating conference.

[10] Lord Crewe refused to "accept" a proposal, stating only that Britain would not place obstacles to such a meeting or object to a conference if it actually came to fruition.

[9] In the meantime, while the delegates were abroad, Aletta Jacobs was putting pressure on the Dutch Prime Minister Pieter Cort van der Linden to host the conference at the Hague.

Van der Linden wanted assurances that President Woodrow Wilson would favor conference and sent Jacobs on an official inquiry mission.

[13] In 1919, Ramondt-Hirschmann traveled with Jacobs and Mien van Wulfften Palthe to the ICWPP meeting in Zürich, where the organization changed its name to the Women's International League for Peace and Freedom (WILPF).

[1] Between 1924 and 1926, she toured various cities in the United States, making speeches about peace,[17][18][19] while her daughter was completing post graduate work at Bryn Mawr College.

[22] During 1936, she served on the Supervisory Board of the Central Peace Bureau and began her participation in collecting relief funds for those in need due to the Spanish Civil War.
