Memento of the Telephone Operating Units Signal Corps (1918)
📖 Review & Summary
The Memento of the Telephone Operating Units – Signal Corps (1918) is one of the most evocative surviving artifacts of the “Hello Girls,” the pioneering U.S. Army Signal Corps female telephone operators who served in France during World War I. Published at Christmas 1918 by the American Expeditionary Forces, the booklet was a combined souvenir and commendation volume presented to the operators as a token of gratitude for their exceptional service under wartime conditions.
Each copy included messages of appreciation from commanding generals, portraits of officers and operators, and candid photographs taken in field exchanges across France. The production quality, bound in simple brown board with a string tie, reflected both wartime austerity and sincere recognition. Within its pages, these women were addressed not as clerks or contractors, but as fellow soldiers who had “braved the dangers of the sea and faced the vicissitudes and discomforts of service on a distant foreign shore.”
Beyond its rarity, the Memento stands as a vital link between wartime experience and postwar memory. It documents a moment when the Army itself, despite later bureaucratic denial, informally acknowledged the women’s military identity. For teachers and students, it serves as a tangible case study of how artifacts preserve the lived reality of service members whose official records did not reflect their sacrifice.
The booklet’s later rediscovery and inclusion in museum and archival collections—often accompanied by personalized copies like that of Operator Delta E. Hagan—has helped historians trace the human story behind the legislative recognition of the Hello Girls in 1977. Today, the Memento continues to remind us that acknowledgment may come late, but preservation ensures it is never forgotten.

Back Story
During WWI, General "Black Jack" Pershing realized that his communications were severely hampered by not having English-speaking phone operators. He advertised in major American newspapers the need for female telephone operators.
The selection criteria were a college degree, the ability to speak French, and being unmarried. The women were recruited from the American Telephone & Telegraph Company (AT&T). Over 7,000 applied, and 450 were selected.
They were trained in basic military radio procedures at Camp Franklin, Maryland, now Ft Meade. After training, the women purchased their Army regulation uniform complete with "U. S" crests, Signal Corps crests, and "dog tags". In the spring of 1918, the first thirty-three operators were en route to Europe. They were issued gas masks and steel helmets.
After the Armistice, and upon their return to the U.S., the operators realized that all Army regulations were worded in the 'male' gender, so the women were denied veteran status. Despite wearing regulation uniforms and following all regulations, they were considered civilians working for the Army.
The Chief Telephone Operator, Grace Banker, received the Distinguished Service Medal from the United States Congress.
For years, legislation had been introduced into Congress, but the bills were always buried in committee. One of the operators, Mearle Eagan Anderson, lobbied for 50 years to secure legislation to award the operators veteran's status.
Their struggle for recognition was a long and arduous one. In 1978, President Jimmy Carter signed the bill giving women their deserved recognition and full military benefits, finally serving the justice they had long awaited. (U. S. Army Signal Corps Museum. )

🏛️ Legacy & Recognition
The Memento of the Telephone Operating Units – Signal Corps stands as both a celebration of service and a symbol of an injustice that would take nearly sixty years to correct. Each copy was distributed to the U.S. Army’s female telephone operators at Christmas 1918 in France — a gesture of gratitude from the Signal Corps officers who regarded them as comrades in uniform.
Yet, when these same women returned home, they discovered that their Army oath and uniforms did not entitle them to military recognition. For decades they were denied veteran benefits and burial rights, despite having served under military command, in uniform, and under fire.
In 1977, after years of advocacy by surviving operators such as Merle Egan Anderson, Congress passed legislation recognizing the Signal Corps Female Telephone Operators Unit as part of the U.S. Army. President Jimmy Carter signed the bill into law in 1978, finally granting the “Hello Girls” the veteran status they had earned in 1918.
Today, the Memento serves not only as a rare artifact of wartime communication but also as a reminder of perseverance — proof that courage in service often precedes recognition in history.

Who were the Hello Girls?
- Unit: Officially known as the Signal Corps Female Telephone Operators Unit, they were a group of about 400 American women recruited during WWI.
- Recruitment: With few exceptions, the operators had to be fluent in both French and English.
- Service: Many worked near the front lines in France, maintaining critical telephone communications for the military. They often worked long hours in hazardous conditions, including enduring artillery attacks.
- Disputed status: Despite being sworn into the Army, wearing uniforms, and being subject to military control, the women were retroactively classified as civilians and denied veteran benefits at the end of the war.
- Veteran status: After a decades-long struggle led by operator Merle Egan Anderson and others, surviving Hello Girls were finally granted veteran status in 1978 when President Jimmy Carter signed the necessary legislation.
✨ Most Engaging Content
The most engaging aspect of the Memento of the Telephone Operating Units – Signal Corps is its dual purpose — part souvenir, part official commendation. Within its pages, officers of the American Expeditionary Forces addressed the women directly, expressing respect and gratitude in a tone rarely extended to female personnel at the time.
Each inscription reads as both farewell and validation: an acknowledgment that these women had shared the same dangers, lived under the same orders, and upheld the same discipline as their male counterparts. The inclusion of personal photographs, rosters, and signed notes from operators like Miss Delta E. Hagan transforms what could have been a standard Army report into a deeply human document — a collective remembrance of service, friendship, and pride.
This blend of military formality and heartfelt gratitude makes the Memento a uniquely personal window into the wartime experience of the “Hello Girls,” bridging the gap between official record and lived history.
