Providing a rare glimpse into one of the finest private art collections in the world, this book presents the extraordinary collection of the Neue Galerie's co-founder, Ronald S. Lauder. This book accompanies an exhibition of the Lauder collection at the Neue Galerie, which celebrates its tenth anniversary in the fall of 2011. The book focuses on six areas: medieval art, arms and armor, Old Master paintings, nineteenth- and twentieth century drawings, fine and decorative art of turn-of the twentieth-century Vienna, and modern and contemporary art. It features works by Constantin Brancusi, Paul C zanne, Vasily Kandinsky, Ellsworth Kelly, Gustav Klimt, Jackson Pollock, Piet Mondrian, and Pablo Picasso, among many others. Essays by medieval art specialist William Wixom; Stuart Phyrr, arms and armor curator, Metropolitan Museum of Art; esteemed drawings collector Eugene Thaw; independent scholars Christian Witt-Dorring and Alessandra Comini; and Ann Temkin, chief curator of painting and sculpture, The Museum of Modern Art, discuss how the Lauder collection was assembled and round out this generously illustrated volume. Encompassing a broad range of masterworks, this book offers an in-depth look at the Lauder collection through numerous illustrations and scholarly essays.
