When the gates of the 1964–1965 New York World's Fair swung open on April 24, 1964, the first of more than 51 million lucky visitors entered, ready to witness the cutting edge of worldwide technology and progress. Faced with a disappointing lack of foreign participants due to political contention, the fair instead showcased the best of American industry and science. While multimillion-dollar pavilions predicted colonies on the moon and hotels under the ocean, other forecasts, such as the promises of computer technology, have surpassed even the most optimistic predictions of the fair. The 1964–1965 New York World's Fair: Creation and Legacy uses rare, previously unpublished photographs to examine the creation of the fair and the legacies left behind for future generations.
