The temple-pedimented bookcase has a fretwork frieze and waist molding taken from a design by William Pain illustrated with designs for chimneypieces in The Builder's Companion and Workman's General Assistant, 1758, pl. 62. Similar rounded cupboard door panels appear on a design for a library bookcase by Thomas Chippdendale published in The Gentleman and Cabinet-Maker's Director, 1st ed., 1754, pl. LXVII. Chippendale also introduced fretwork friezes topped by urns on the flanking elements of a bookcases he designed in 1759, published in the third edition of his Director, 1762.
This bookcase belonged to Margaret Phipps Boegner, the grand-daughter of Henry Phipps, who in 1861 joined Andrew Carnegie in the steel venture that became a core part of the United States Steel Corporation at its founding in 1901. Her parents, John and Margarita Phipps, built an English Restoration-style manor house called Westbury House in central Nassau County and furnished it with eighteenth-century antiques. The manor house and gardens at Old Westbury are open to the public.
