Paul Mellon (1907–1999) was an unparalleled collector of British art. His collection, now at Yale in the museum and study center he founded to house it, rivals those in Britain’s national museums and is unquestionably the most comprehensive representation of British art held outside of the United Kingdom. This book and the exhibition that it accompanies celebrate the centenary of his birth. Five introductory essays examine Mellon’s extraordinary collecting activity, as well as his role in creating both the Yale Center for British Art and the Paul Mellon Centre for Studies in British Art in London as gifts to his alma mater (Yale 1929). A lavishly illustrated catalogue section showcases 148 of the most exquisite and important paintings, watercolors, drawings, prints, sculpture, rare books, and manuscript material in the Yale Center’s collection, including major works by Thomas Gainsborough, Joshua Reynolds, George Stubbs, John Constable, and J. M. W. Turner.
