The town of Ferney, where Voltaire lived out the last 20 years of his life, was officially named Ferney-Voltaire in honor of its most famous resident, in 1878. His "château" is a museum. Voltaire's library is preserved intact in the National Library of Russia at Saint Petersburg. In the Zurich of 1916, the theatre and performance group who would become the early avant-garde Dada movement named their theater the Cabaret Voltaire. A late-20th-century industrial music group later adopted the same name. Astronomers have bestowed his name on the Voltaire crater on Deimos and the asteroid 5676 Voltaire.
