In the fourth of our series of programs on the World’s Fair Expo Milano 2015, host Mitchell Davis (Executive Vice President of the James Beard Foundation and Chief Creative Officer of the USA Pavilion) is joined by historian and Associate Professor of History at Drexel University Scott Knowles to discuss the history of the World’s Fair. From the World’s Fair’s origins in London, to Paris, to Chicago, and finally to New York in 1939 and 1964, learn how the pavilions have evolved over the years to reflect changes in society across the globe and what the future of the World’s Fair might hold.
