Gropius House
A Modern Call System
The Electric Annunciator
An electric call box system facilitated communication between the Eustises and their staff. A family member would push a wall-mounted button in one of twenty spaces throughout the house, causing the bell at the top of the call box to ring and the specific room that was calling to be indicated. Depending on the room, a parlor maid, chamber maid, waitress, or other staff member would attend to the family member calling.
