The observation tower erected by the American DeForest Wireless Telegraph Company was brought to the Fair when it became a hazard near Niagara Falls and needed to be removed because in the wintertime, ice from the fall's mist would form on the steel structure, and eventually fall onto the buildings below. It served as a communications platform for Lee DeForest's work in wireless telegraphy and a platform to view the fair. As Niagara Falls was near Buffalo New York, it was also called the Buffalo Tower After the World's Fair, it was moved to Creve Coeur Lake to be part of that park.
