[11] Man Ray, who had recently relocated from Hollywood to Paris, introduced her to the artist and art patron William Copley whom she married on December 31, 1953.

[13] The Copleys acquired an estate in Longpont-sur-Orge, outside of Paris, which became a magnet for members of the Parisian interwar avant-garde who had dispersed during the war.

[15] During this period, the couple expanded their collection, building upon works Bill had acquired in the course of running the Copley Galleries in Hollywood in 1947–48.

[16] The collection included iconic works by such 20th-century masters as Man Ray, Duchamp, Giorgio de Chirico, Hans Arp, René Magritte, Max Ernst, and Yves Tanguy.

[4] In 1954, the couple launched the William and Noma Copley Foundation, dedicated to helping emerging artists and composers through grants.

The foundation gave grants to such emerging composers as John Cage and Benjamin Lees, and artists Joseph Cornell, Vija Celmins,[18] Joseph Kosuth, Dieter Roth, Carolee Schneeman, Bruce Naumann, Christo, and Pop art pioneers Eduardo Paolozzi and Richard Hamilton.

The Sotheby Parke Bernet auction of the Copley collection in New York on November 5–6, 1979 set records for many of the artists in the sale.

[24] A review of her work in the Los Angeles Times described her “Pop-surreal” jewelry as consisting of “beautifully wrought objects that reflect not only wit and sophistication but a highly individualistic spirit.

[35] Papers and correspondence related to her activities with the William and Noma Copley Foundation and with Marcia Tucker are located in the Getty Research Institute, Los Angeles.
