George Washington Maher was a contemporary of Frank Lloyd Wright's, and utilized many of the same elements in his houses, but with markedly different results.  Whereas Wright's architecture could be characterized by an overt geometry, Maher's was somewhat softer, relying on the accumulation of various decorative materials to give his interiors a more conventional Arts & Crafts feeling.  His sources could be as diverse as the architecture of English architect CFA Voysey or the plans and drawings by Harvey Ellis, which Maher would have seen in the various magazines of the period.  Like Wright, however, Maher's architecture has a consistency to it that speaks of an organizing intellect that was involved in every aspect of a project, from large to small. If the project allowed, Maher would design furniture, lighting, windows and various other items for his houses, repeating a specially-selected motif, or group of motifs, that were intended to symbolize the essential character of the client.
This window was designed for the Arthur Stone house, originally in Kalamazoo, Mi, but now demolished.  The flower is a rare white bluebell, recently introduced in the period from Russia.
