A friend recommended to see, during my visit in NYC, the beautiful house of Duveen. He said that this is near Central Park, but does not remember well.
I could not find any thing on net about this, I saw that a big building (where Duveen had offices) on 5th Avenue had been demolished in 1952.

Can somebody help with more info?

Not sure - he helped design the interiors of the Frick - I believe.

Yes Sue, you are right. But I asked about his house.

Sorry - can't help - lots of other interesting material about him on the net.

Perhaps your friend was thinking of the Frick Collection, since it is located in what was Frick's house. It is opposite Central Park.

(I've lived in NYC for 35 years and have never heard of Duveen's house.)

Thanks, Ellen, I visited Frick house; I have to ask my friend and if he is right, I'll post here the location.

This is a quote from Christopher Gray's article about mansions in the NY Times Sunday.

Others built their own art shrines: The art dealer Joseph Duveen put up a chunky neo-Classical box designed by John Russell Pope. Built in the 1920s, it was adjacent to his house at 15 East 91st Street; both have since been demolished. In the same period the sculptor George Grey Barnard assembled a gallery from antique architectural elements, later razed to become the nucleus of the Cloisters museum.

This is or was between my neighborhood and the Park.

Sue, I have not enough words to thank you for this link. It is very intersting and comes exactly at the right time (in three weeks my vacation will start !!!).

Regarding Duveen houses, I found in internet two addresses, 720 5th Ave at corner with 56 Street and another, 15 East 91st street at corner with Madison Ave; both buildings have been demolished. So, my friend, who was sure that two years ago saw Duveen's houses, is very disappointed!

He probably saw the Morgan and the Frick - am sure Duveen had a hand in both

Yes, you are right, Duveen helped them to make their art collections.
My friend did not refered to these museums, but to the houses where Duveen had his galleries or where he lived.
