The Fondation Louis Vuitton by Frank O. Gehry rises from the Bois de Boulogne as a new landmark in the Parisian skyline. Gehry's dynamic architecture is both glittering and multifaceted: is it a sailing vessel, an iceberg, or a sea monster? It fascinates with its wealth of references and, at the same time, escapes any clear-cut definition. Three outstanding representatives of different generations of art history, James S. Ackerman (†), Irving Lavin, and Horst Bredekamp have together paid a visit to the Fondation Louis Vuitton. They explore the building in three richly illustrated essays that try to fathom the floating architecture of the "magician" Gehry in the context of both art and architectural history.
