About WWI

Grace Banker was the Chief Operator of the U.S. Signal Corps’ women telephone operators.

Edith Cavell was a British nurse who operated a medical clinic and nursing school in Brussels at the start of the war in August 1914.

At the outset of World War I, women in the United States did not have the right to vote in national elections and could not serve in the military.

On Nov. 11, 1918, after more than four years of horrific fighting and the loss of millions of lives, the guns on the Western Front fell silent. 

Formally opened on Jan. 18, 1919, the Paris Peace Conference was the international meeting that established the terms of peace after World War I. 

With millions of men away from home, women filled manufacturing and agricultural positions on the home front.
