UT History professor Ernie Freeberg speaks with UT historian Dr. Shellen Wu, a specialist in modern Chinese history. She helps us understand the origin and legacy of the fair’s most popular exhibit, the pavilion hosted by the People’s Republic of China.

In our first episode, UT History professor Ernie Freeberg speaks with historian Michael Camp, who has written a book on energy policy in the 1970s and 80s. Camp says that the long lines at the gas pumps caused by the energy crisis of 1973/74 set the stage for the Carter administration’s focus on energy conservation—and inspired its support for Knoxville’s proposal to host an international energy exposition almost a decade later.
