"[3] It was designed to be only six stories tall by the architects, A. Stewart Walker and Alfred Easton Poor, to allow light to reach the nearby Carlyle Hotel.

[8] In March 1966 Peregrine Pollen, then president of Sotheby Parke Bernet, used the building for a concert by pianist Philippe Entremont.

[10] On June 9, 1987, Sotheby Parke-Bernet announced that it was closing the galleries, causing an uproar in the New York City art community.

I think a lot of the glamour that has characterized the art market in New York over the last 20 years is going to disappear when Sotheby's leaves the premises.''

[8] The building was then divided into small rooms for tenants and included in the Upper East Side Historic District.

Also in 1987, Larry Gagosian leased a small office there, gradually growing into it a multi-floor operation that eventually spanned nearly half the entire building.

[2][12] The tower was designed by Norman Foster[13] and supported by prominent figures such as Jeff Koons, Tory Burch, and Ronald Perelman.

[20] Rosen's company, RFR Holding, obtained a $238 million commercial mortgage-backed security loan for the building in 2021.

[23] RFR proposed leasing 85 percent of the building's space to Bloomberg Philanthropies in October 2023, displacing Gagosian from the site.
