The three buildings are New York City designated landmarks, and the entire ensemble was added as a group to the National Register of Historic Places in 1982.

[1] In early 1916, stockbroker Francis Fletcher Palmer (1874–1923)[2] bought a lot in Manhattan on the northwest corner of East 93rd Street and Park Avenue, which as recently as 1913 had been occupied by a Roman Catholic school for girls, run by nuns of the Ursuline order.

[3] To facilitate construction of a new house, Palmer (or the previous owner of the property) demolished the two school buildings on the site.

[4] Palmer engaged the architects Delano & Aldrich, who designed a neoclassical house with a handsome white-marble balustrade, separating a three-story brick facade from a two-story slate mansard roof.

He died of pneumonia in April 1923,[5] and in May 1926, his heirs sold the house to financier George Fisher Baker Jr. (1878–1937).

In a memo dated September 1927, Percival Gallagher (1874–1934), a landscape architect with Olmsted Associates,[10] advised Mrs. Baker, "The fountain is in rather bad condition.

"[11] In 1930, following completion of construction work adjacent to the garden, the Bakers bought a bronze triton fountain created by the Swedish sculptor Carl Milles.

[12] In September 1930, George Baker bought the twenty-two-foot wide lot at 67 East 93rd Street, immediately west of his garage building.

(Before doing so, she donated two antique chandeliers from the ballroom, each with about eighty rock crystal prisms, for use in the White House.)

[17] After a public hearing on November 10, 1966, the Landmarks Preservation Commission voted on January 14, 1969 to designate 75 East 93rd Street a landmark, declaring it to be "an outstanding example of a modified Federal style...one of the finest works in New York City, by the architects, Delano and Aldrich."

Eddie Ulmann was a graduate of Phillips Exeter and Columbia College; an eight-time amateur national racquets doubles champion; member of numerous gentlemen's clubs; and author of a gossip column for the magazine Quest, written under the pseudonymous by-line, "Corinthus.

In November 2018, the Classical American Homes Preservation Trust, a foundation created by Jenrette, acquired the house.

69 East 93rd Street...I liked the light and the height of the ceilings, but the house lacked a grand ceremonial entrance staircase as I had enjoyed next door at No.

67 East 93rd Street...I even went so far as to commission Michael Dwyer, my favorite young neo-classical architect in Manhattan, to design a new interior layout.

His plan 'borrowed' half the six-car garage on the first floor and would have created an elegant entrance hall and elliptical staircase ascending to the piano nobile..."[29]: 161 In 1996, Jenrette moved back to No.
