 Several of the rooms also included Tiffany glass lamps or fixtures that were designed by de Forest and created in the Tiffany Studios.In the 1894–1896 renovations to the Deanery, Lockwood de Forest transformed the original living room into a study for M. Carey Thomas, which came to be known as the "Blue Room," referring to the room's dark blue walls.The decoration of the Blue Room was inspired by Japanese art, a departure from the East Indian influence that permeates the majority of de Forest's designs in the Deanery.
