Architecture and the built environment are formed by many collaborators and events. Sometimes ideas remain on paper and unrealized. Often, these behind-the-scenes stories are little known.

John C. Guenther, FAIA, LEED AP, will present an unrealized ultimate plan by Cass Gilbert for the St. Louis Art Museum, discuss the meaning of the ornamentation of the façades of the Wainwright Building, describe the search by Principia College for a new college campus, review how the sculptural form of the Gateway Arch evolved,  reveal how the Missouri Botanical Garden might have been home to a symphony hall, show where AIA Gold Medalist, César Pelli, FAIA, architect of the 88-story Petronas Towers in Kuala Lumpur, designed three early projects in St. Louis, share an important home designed by the great modern designer, Charles Eames, who returned home to St. Louis, and reveal how the St. Louis Zoo Monument – the sculptural stone column alongside Highway 40 – came to be.
