The seven Fisher brothers, who owned the automotive company Fisher Body, essentially gave architect Kahn a blank check to design and build the "most beautiful building in the world." This was the Fisher Building (1927) which, with its detailed work, has been called the city's "largest art object." Its opulent three-story, barrel-vaulted lobby is constructed with forty different kinds of marble. Albert Kahn Associates chief architect for the Fisher Building was Joseph Nathaniel French. The Fisher Building and Cadillac Place are among the National Historic Landmarks in Detroit anchoring the city's historic New Center.
