The U.S. military needed skilled operators to handle the telephones in World War I. Known as the Hello Girls, 223 U.S. women served in France. Some worked near the front lines with Gen. John "Black Jack" Pershing, the top U.S. commander. Here, the women work in Seine, France, in 1918. Their story was largely forgotten, but is being recognized on the 100th anniversary of the end of the war.
