History

The DuPont-Guest Estate, now known as De Seversky Mansion, is a historic estate located at Brookville in Nassau County, New York. 

The home, originally called "White Eagle", was built between 1916 and 1918 for Alicia Heyward (née Bradford) Maddox, the second wife of Alfred I. du Pont and daughter of Judge Edward Bradford. It was designed by the architectural firm of Carrère and Hastings in the Georgian Revival style and the interiors were designed by Charles of London. The residence is two stories plus a basement level, with a red brick façade, white marble and limestone embellishments, and a gabled, slate roof.

Alicia du Pont died in January 1920 before the home was finished.
The estate consists of the residence, surrounding landscaping, and garage. It adjoined Harbor Hill, the country seat of Clarence Mackay (to the north), and the home of Harry Payne Whitney (who married Gertrude Vanderbilt) (to the south). It was near to the "homes of many of America's leading financiers, including Nicholas F. Brady, Otto H. Kahn, J. Pierpont Morgan, Thomas H. Hitchcock, Elbert H. Gary and Ormond G. Smith."

In 1921, the estate (which had been completed and fully furnished in January 1921, but never lived in), which was valued at over $1,500,000, was to be sold at public auction conducted by Arthur C. Sheridan for the benefit of Mrs. du Pont's child by her first marriage, Alicia Maddox, who had been adopted by Alfred du Pont. It was sold for $470,000 to David T. Layman Jr., who was understood to be acting for Howard C. Phipps of the Phipps family.
The property was purchased in the 1920s by Frederick Guest (husband of Amy Phipps) and his family, who called it "Templeton". It was listed on the National Register of Historic Places in 2009.

Even with its modern updates, exploring the mansion's historic interior is like stepping back in time. The main ballroom, with its hand-carved wood-paneled walls and large stone fireplace, originally served as the living room. The Library was once a study, the Pub was a breakfast room, and the Terrace Room had a previous life as the formal dining room, where such illustrious guests as Truman Capote, Salvador Dali, and the Duke and Duchess of Windsor were entertained.

Precautions

The DeSeversky Mansion has implemented several new policies and procedures, which follow recommendations from the U.S. Centers for Disease Control and Prevention (CDC). The Mansion is in constant communication with their employees to reinforce our sanitization safety procedures in both guest-facing and back-of-house areas. The mansion is ensuring high-traffic public areas are sanitized at an increased frequency.

Hand sanitizers are located throughout the front-of-house and back-of-house locations. Sanitizers are refilled and checked regularly. Public touch points, such as handrails, door handles, and knobs are sanitized by their housekeeping department at least hourly during high-traffic times throughout the day. The bars will be disinfected each hour to include bar tops, refrigerators, and bottles. All surfaces and equipment in the kitchen and back of the house are sprayed down directly with a food-safe disinfectant solution throughout the shift. Stemware, flatware, and china, once cleaned and sanitized, will not come in direct contact with Mansion employees before being set. The Mansion has implemented hand washing or sanitizing procedures to take place multiple times during their employees shifts.

All employees at the Mansion are instructed each day on correct hand sanitizing procedures and also instructed to inform guests on locations of sanitizing stations. Individual employees at the Mansion have also been equipped with disinfectant wipes to be used. Their employees are instructed to wash hands before and after every task performed. Proper procedures and CDC guidelines are posted in all back-of-house work areas. All employees of the Mansion are prohibited from reporting to work with a respiratory illness.
