McKean,[3] who had been an art student at Tiffany's Laurelton Hall estate in 1930, remembered Jeannette's exact words at the scene of the devastation: "Let's buy everything that is left and try to save it."

Among these acquisitions were parts of Tiffany's 1893 chapel for the World's Columbian Exposition; award-winning leaded glass windows; and major architectural elements such as the poppy loggia, which was donated to the Metropolitan Museum of Art and installed in the Charles Englehart Court.

In February 2011, the Morse opened a wing that provided for 6,000 square feet (560 m2) gallery space for the permanent exhibition of its collection of art and architectural objects from Tiffany’s Long Island country estate, Laurelton Hall.

[6] Other leaded-glass windows in the collection include work by William Morris, Louis Sullivan, Frank Lloyd Wright, John LaFarge and Arthur J. Nash.

Prints include work by some of the same artists as well as Grant Wood, Mary Cassatt, Paul Cézanne, Childe Hassam, John Steuart Curry, and Edward Hopper.
