Over the past four years, The Frick Collection has renovated its galleries and public spaces through a succession of critically acclaimed initiatives. Availing itself of advances in lighting technology, the Frick has improved dramatically the illumination of its paintings, sculpture, and decorative arts. Following a three-month closure, the Boucher Room recently reopened to the public, having been refurbished and relit, the first such extensivetreatment ofthis jewelbox of a gallery in almost thirty years. The long West Gallery—home to masterpieces by Rembrandt, Hals, Turner, and Vermeer, as well as Renaissance bronzes and furniture and considered by many to be the centerpiece of the museum—is undergoing the first substantial relighting since the Frick opened to the public seventy-five years ago. While an upgrade of existing auxiliary lights occurred more than twenty years ago in this gallery, the 2010 project relies on a new custom system and represents a major rethinking of the illumination of the room and the collectionsshown there.
