I had the pleasure of viewing the Joseph Urban exhibit at the Flagler Museum in Palm Beach a few weeks ago. You can see some of the piece on display, including rendering for Ziegfeld, Metropolitan Opera and Palm Beach Paramount, at this link http://www.flaglermuseum.us/exhibits. The exhibit includes a piece of the ceiling mural from the Ziegfeld.
The book written by John Loring has even more wonderful material http://www.amazon.com/Joseph-Urban-John-Loring/dp/0810990261
If you have a good Internet connection you can see and hear John Loring’s lecture here: http://www.opal-online.org/Flagler20110220Urban/. Alll the lectures this year were about architecture and are viewable on-line - The Architects Who Designed Palm Beach’s Iconic Buildings.
Last year I got to attend several events relating to the 2010 Whitehall Lecture Series – Popular Entertainment During the Gilded Age – which are still available on-line. Great coverage of the subject including Nikelodeon City: The Origins of the Movie Industry. See the lectures here:
