From Wikipedia Elsie Janis (March 16, 1889 – February 26, 1956) was an American singer, songwriter, actress, and screenwriter. Entertaining the troops during World War I immortalized her as "the sweetheart of the AEF" (American Expeditionary Force).

Janis was a tireless advocate for British and American soldiers fighting in World War I. She raised funds for Liberty Bonds. Janis also took her act on the road, entertaining troops stationed near the front lines - one of the first popular American artists to do so in a war fought on foreign soil.
