The mansion during Keene's time, 1902-1930's
Foxhall Keene and William Luttgen on the driveway of Rosemary Hall.
Since the origin of the car determined the entry's representation, American-born Keene and his Mercedes drove for Germany. Regardless, spectators cheered wildly when Keene and his #5 racer reached to the 1905 Mineola starting line on Jericho Turnpike.
Keene suffered an injury when he crashed his car into a telegraph pole during that year's Vanderbilt Cup Race with Keene's mechanician William Luttgen pinned under the car. Luckily neither was seriously injured.
A 1913 NYTimes article mentions that Keene had broken his collar bone four times. He had "twice been carried from the polo field for dead. He has had falls as an amateur steeplechase rider, been blown up from an automobile, nearly drowned on a sinking yacht, dragged by runaway horses and bitten by dogs". (I surely hope he had excellent medical coverage!)
He retired in 1931 and moved to Canada to live with his sister, passing away in 1941

That’s “Rosemary Hall”, home of Vanderbilt Cup racer Foxhall P. Keene who participated in the 1905 and 1908 races but did not finish in either one. It is still standing and is currently a private residence on Mansion Drive in Old Westbury. Traditional legend has it that Delmonico’s restaurant in NYC named a new dish “Chicken a La Keene” after it was suggested to the chef by Foxhall. The menu item has evolved into “Chicken a La King”. However, according to Delmonico’s website, it was actually suggested by Foxhall’s father, James R. Keene (see attached).
The estate is called “Deepdale” located in Lake Success, the home is still standing and is located at 10 Westcliff Drive, Lake Success.
The home was built by William K. Vanderbilt II, and is the founder of the Vanderbilt Cup Race.

This is Rosemary Hall built by Foxhall Parker Keene who is credited with the creation of Chicken al a King. He was a driver in the Vanderbilt cup races. The estate’s property has been subdivided and is located at the end of mansion Drive in Old Westbury. I was involved with a renovation that took place there about 20 years ago.
This is “Rosemary Hall” on Mansion Drive in Old Westbury, built for Foxhall P. Keene who was a part of the 1905 Vanderbilt Cup Race. Chicken à la King was derived from his name.
The estate was called Harbor Hill- it was located in Roslyn/East Hills NY overlooking Hempstead Harbor.
It was torn down in 1947.
The owner was Industrialist and chairman of the Postal Telegraph and Commercial Cable company Clarence Mackay.
Mackay was friends with William K. Vanderbilt Jr., and a director of the Motor Parkway. Mackay would often attend the Vanderbilt Cup Races and entertain guests and dignitaries at his estate after the races.
The dish named after him was “Cotelettes de Volaille Clarence Mackay” a fancy chicken dish.
Rosemary Hall, yes still standing.

The estate called “Deepdale” was owned by William K. Vanderbilt II. The home is
self, still exists at 10 Westcliff Road, Lake Success, N.Y.
The estate also housed a golf course with a clubhouse, which is now owned by the Village of Lake Success. The original Deepdale golf course and clubhouse has been split, and what is presently called Deepdale is not what the village owns. Although decades later in 1954, the region began transitioning into suburbia, and the Long Island Expressway embedded itself right through the northern part of the course. After a failed attempt to reengineer the course, the club purchased the W.R Grace estate, which was located in close proximity. The current Deepdale course and club in Manhasset is the relocated Deepdale, but the Lake Success course and club will forever stand as a reminder for what once was.
The original owner, William K. Vanderbilt II was also the founder of the
Vanderbilt cup races.
