The Yeomenettes greatly expanded the opportunities for women in the Navy. One job the women learned was telegraphy, using a telegraph to send messages via wires over long distances using Morse Code. The Morse telegraph was invented in the United States in 1936, and by 1861, telegraph cables stretched not only across the United States but also under the Atlantic Ocean to Europe.
In this photograph, new enlistees receive training in telegraphy from a Chief Petty Officer, at the Naval Training Center, Great Lakes, Illinois, in 1917. Some of these women are in uniform while others are still wearing civilian attire.
