Urso Chappell founded ExpoMuseum 1998, with the ultimate dream of seeing ExpoMuseum become a physical museum dedicated to the history of all world expositions - in much the same spirit as the Olympic Museum in Lausanne, Switzerland.
Ever since attending his first world's fair in 1982, Urso was fascinated by nearly every aspect of them. He continued to be inspired by the potential of future expos and their enormous capacity to educate and inspire the public to see beyond everyday life. Combining his interest in design, architecture, culture, history, internationalism and communication, the potential of world's fairs became a passion for Urso which eventually led to the creation of ExpoMuseum, the preeminent online world's fair source. Over the years, he attended eleven international expositions, wrote for various publications, consulted on Expo bids, and worked with Milan's Expo 2015 to create the Expo 2015+100 Archive.
Sadly, in December 2020, Urso Chappell passed away. A group of friends and colleagues took over ExpoMuseum to keep his legacy alive.
