One of the more poetic interiors at any American Museum is the fireplace and doorway from the library of the Curtis and Nellie Lee Bok House in Radnor, Pennsylvania. The father of the Furniture Studio Movement, Wharton Esherick crafted and carved this ensemble in 1936. Considered as one of his finest early work, its angular design was inspired by German Expressionism and Czech Cubism. The spectacular corkscrew-like spiral staircase that Esherick did for the same house, is a part of the collection of the Wolfsonian today. While the bottom step forms a circle, the top step forms a triangle and the steps intermediate progressively from the bottom to top step.
