"The entrance hall provided an appropriately impressive area for receiving visitors. Leon Marcotte of New York and Paris carved the entrance hall’s ornamental detail when the house was built. In 1881, the interior design firm of Louis C. Tiffany & Co., Associated Artists, was hired to stencil the room’s original wainscoting in silver, and paint the walls and ceiling red with patterns of black and silver. They drew inspiration from the other cultures such as the Middle East and Asia to form a cohesive design scheme that flowed throughout the first floor and public spaces of the house."
