Memorial book fund at the Frick

Because the Frick Art Reference Library in New York City was a precious resource for Richard Weisberg’s research and a place where he always felt at home, a book purchase fund has been established in his memory by his wife Kathryn Annette Clark to aid scholars and students for years to come.  Anyone wishing to add to the Richard E. Weisberg Book Fund may send a tax-deductible contribution to The Development Office, The Frick Collection at 1 East 70th Street, New York, NY 10021.  Please direct any inquiries about the Fund to The Andrew W. Mellon Chief Librarian at the Frick Art Reference Library, 10 East 71st Street, New York, NY 10021.
