LACMA's Unframed blog is reporting that the museum has (finally) acquired a long-coveted Arthur Heygate Mackmurdo chair, as a joint acquisition with the Huntington. The c. 1883 mahogany and leather seating is billed as the chair that started Art Nouveau. To curator Wendy Kaplan, it was simply "That Chair." It's one of five known chairs from a set, the others at the Victoria and Albert Museum, the William Morris Collection, London (which has two), and the Virginia Museum of Fine Arts. The Huntington will show it first, for a two-year period starting next month.
