Jack Daniel’s heir Laura Lee Brown and husband Steve Wilson, the mega-art collectors behind Louisville’s boutique 21c Museum Hotel, are expanding the concept, and their collection of 2,500 artworks, to 13 more locations. Brown — an heiress to the Brown-Forman liquor conglomerate which also owns Southern Comfort — and Wilson’s 21c is a 90-room boutique hotel and museum that’s played home to work by Chuck Close, Kara Walker, Tony Oursler, Andres Serrano and Sam Taylor- Wood, plus projects by Mikhail Baryshnikov and John Waters. Like their first 21c, the new locations’ museums will be free of charge and open ’round the clock. Construction is under way in Cincinnati; Lexington, Ky.; and Bentonville, Ark. Brown and Wilson hope to expand the concept to 10 more cities over the next year, and there are plans for one close to New York. Their Louisville base houses a hotel, museum and restaurant in a series of redesigned 19th-century warehouses.
