The Chicago History Museum has announced that their Chief Historian Emeritus and Trustee Emeritus Russell Lewis passed away today. Lewis was an eminent World’s Columbian Exposition historian, authoring significant collections such as Historic Photos of the Chicago World’s Fair (Turner, 2010) and Remembering the Chicago World’s Fair (Turner, 2011). His recent article “A Wheel With a View” in Summer 2017 issue of Chicago History described the Ferris Wheel. We delighted in, and were enriched by, his presentations on the World’s Fair and other aspects of Chicago history at the Museum and around the city.
