Women have been always affected by wars. After World War I, activities outside the home were mobilized and carried out, such as the employment of jobs in all sectors to bridge the gap left by the men called up; they also carried out health and humanitarian care; in some countries they were also on the war front.
Violetta Thurstan is one of them, who was noted for his health and other rearguard duties in World War I, the Spanish Civil War and World War II. In the field of health care, the physicians Elsie Inglis and Frances Ivens were appointed during the First World War. Surgeries Garret, Murray and Buckley were immortalized by painter Francis Dodd while operating at Endell Street Military Hospital in London. The Scottish Women's Hospitals for Foreign Service with its medicalized ambulances provided medical services on the Allied fronts. Marie Curie, supported by the Red Cross and the Women's Union of France, equipped a car with a portable X-ray apparatus and assisted wounded soldiers on the lines of combat.
After World War I, humanitarian aid continued in a destroyed Europe. Save The Children Fund was created in 1919 on the initiative of Eglantyne and Dorothy Jebb to help boys and girls without distinction between victors and vanquished.
During the Spanish Civil War, the international nature of the conflict led to international volunteers (many integrated into the International Brigades) working as doctors, nurses, ambulance drivers, war correspondents, photographers, etc. There were organizations that supported both sides; others collaborated only with the Republican side as the International Red Relief; and, for their part, in the rebel zone acted Social Auxilio founded by Mercedes Sanz-Bachiller and White Relief led by Mª. Rosa Urraca. There were women who volunteered as Elisabeth Eidenbenz herself. Other anti-fascist women in this context include Dolores Ibárruri, Margarita Nelken, Matilde Cantos, Lina Ódena, Encarnación Fuyola and Emilia Elías.
At the outbreak of the Second World War, there is again the mobilisation of women in both humanistic and fighting aspects. And Elisabeth Eidenbenz continued to do healthcare work, as did Lillian Gutteridge, Augusta Chiwy, Elsie Ott, Reba Whittle, etc.
