Verne got the name. James A.M.Whistler is the answer. The room is the multi shelved, paneled, and shuttered peacock room which has been transported to the Smithsonian's Freer Gallery in Washington, D.C., which also has his pictures there, and also in the American Art Museum. As one of the most famous rooms ever, the peacock room is not as it was supposed to be. It was supposed to be completely different colors to highlight shipping magnate, a Mr. Leyland�s blue and white Chinese porcelain collection. Whistler got in a tiff and not only changed the room without permission, but painted symbolic peacocks for Mr. Leyland, entertained Mr. Leyland�s wife, and the then in Leyland�s absence had parties to show off the room (and charged admission) to others. These and other transgressions got him fired. As to the footrest it is plainly seen in the Whistler�s Mother portrait (actually named Arrangement in Grey and Black: Portrait of the Painter's Mother). Whistler it turns out was one of the first room decorators hired for that purpose although he didn�t much listen to the client (so what has changed?). More on Whistler on the link above.
