The 1964-65 World's Fair in Flushing Meadows Corona Park was a curious episode in American cultural history. Planned and executed during a period of intense global unrest, the Fair presented a program of unbridled technocratic optimism and unprecedented corporate sponsorship. Among the legacies of the Fair was a powerful, if temporary, surge of radical architectural and urban innovation. A colossal production, the spectacle of the Fair was marked by a combination of precisely honed logistical and constructional efficiency coupled with a wealth of fantastical experimentation. As quickly as it emerged, the city that was the Fair descended back into fiction, along with the wealth of innovations that could barely be appreciated during their existence. Unraveling the intricacies of this hallucinatory landscape intertwined with the utterly pragmatic concerns of its realization, this submission for the Pamphlet Architecture series seeks to articulate a new urban history of this ephemeral moment.
