Hello Girls was the colloquial name for American female switchboard operators in World War I, formally known as the Signal Corps Female Telephone Operators Unit. During World War I, these switchboard operators were sworn into the U.S. Army Signal Corps.
The “Hello Girls” fought with skill and cutting edge technology — well, cutting edge for the early 1900s. The Hello Girls were the first women to be sent to war by the U.S. Army, working as telephone switchboard operators and connecting 26 million calls throughout the First World War.
Filmmaker Jim Theres tells the story of America's first female soldiers. In 1918 the U.S. Army Signal Corps sent 223 women to France as telephone operators to help win the Great War. But you've probably never heard of them. Now you will!
