It is also an important example of the private residences of architect William B. Tuthill, known for Carnegie Hall, and is considered his finest private home design.","narrative":"Built between 1907 and 1909 at the corner of Riverside Drive and 107th Street, this white marble mansion was commissioned by Morris Schinasi, a partner in Schinasi Bros., Inc., maker of \"Natural\" brand cigarettes. Architect William Burnett Tuthill, who had trained under Richard Morris Hunt and later designed Carnegie Hall, produced what is regarded as his finest private residence. The two-and-a-half-story house has projecting and recessed wall sections, stone balconies, copper oriels, and boldly projecting dormers with curvilinear pediments above a green terra-cotta tile roof. Inside, the marble vestibule with mosaic tile, the coffered oak ceiling in the stairhall, carved dining room panelling and stained glass remain, though upper floors were altered for classrooms. The house matters as a reminder of the era when private mansions were expected to rival Fifth Avenue, before apartment buildings came to line the drive.","period_of_significance":"1907-09","architect_builder":"William B.
