In 1933, architect Alfred Hopkins (noted for his work on Louis Comfort Tiffany's Laurelton Hall Farm on Long Island) designed and built himself this stone Gothic on a leafy street in Princeton, N.J. While Hopkins was a talented architect (a retrospective look at his work was presented at NYC's Metropolitan Museum of Art in 2007), his fame pales in comparison to that of his friend and frequent house guest, Albert Einstein. According to listing agent Peggy Henderson, the brainy physicist regularly practiced the violin in the $2.65M home's inner cloister. Even if you don't buy these claims, that fireplace-cum-doorway is a stroke of genius all its own.
